### INSTALL_SCENARIO_BULK

    public static final int INSTALL_SCENARIO_BULK

Installation scenario indicating a bulk operation with the desired result of a fully optimized application. If the system is busy or resources are scarce the system will perform less work to avoid impacting system health. Examples of bulk installation scenarios might include device restore, background updates of multiple applications, or user-triggered updates for all applications. The decision to use BULK or BULK_SECONDARY should be based on the desired user experience. BULK_SECONDARY operations may take less time to complete but, when they do, will produce less optimized applications. The device state (e.g. memory usage or battery status) should not be considered when making this decision as those factors are taken into account by the Package Manager when acting on the installation scenario.

Constant Value: 2 (0x00000002)

### INSTALL_SCENARIO_BULK_SECONDARY

    public static final int INSTALL_SCENARIO_BULK_SECONDARY

Installation scenario indicating a bulk operation that prioritizes minimal system health impact over application optimization.

### MATCH_DIRECT_BOOT_AUTO

    public static final int MATCH_DIRECT_BOOT_AUTO

Querying flag: automatically match components based on their Direct Boot awareness and the current user state.

Since the default behavior is to automatically apply the current user state, this is effectively a sentinel value that doesn't change the output of any queries based on its presence or absence.

Instead, this value can be useful in conjunction with `StrictMode.VmPolicy.Builder.detectImplicitDirectBoot()` to detect when a caller is relying on implicit automatic matching, instead of confirming the explicit behavior they want, using a combination of these flags:

- `MATCH_DIRECT_BOOT_AWARE`
- `MATCH_DIRECT_BOOT_UNAWARE`
- `MATCH_DIRECT_BOOT_AUTO`

Constant Value: 268435456 (0x10000000)

### MATCH_DIRECT_BOOT_AWARE

    public static final int MATCH_DIRECT_BOOT_AWARE

Querying flag: match components which are direct boot aware in the returned info, regardless of the current user state.

When neither `MATCH_DIRECT_BOOT_AWARE` nor `MATCH_DIRECT_BOOT_UNAWARE` are specified, the default behavior is to match only runnable components based on the user state. For example, when a user is started but credentials have not been presented yet, the user is running "locked" and only `MATCH_DIRECT_BOOT_AWARE` components are returned. Once the user credentials have been presented, the user is running "unlocked" and both `MATCH_DIRECT_BOOT_AWARE` and `MATCH_DIRECT_BOOT_UNAWARE` components are returned.

See also:

- `UserManager.isUserUnlocked()`

Constant Value: 524288 (0x00080000)

### MATCH_DIRECT_BOOT_UNAWARE

    public static final int MATCH_DIRECT_BOOT_UNAWARE

Querying flag: match components which are direct boot unaware in the returned info, regardless of the current user state.

When neither `MATCH_DIRECT_BOOT_AWARE` nor `MATCH_DIRECT_BOOT_UNAWARE` are specified, the default behavior is to match only runnable components based on the user state. For example, when a user is started but credentials have not been presented yet, the user is running "locked" and only `MATCH_DIRECT_BOOT_AWARE` components are returned. Once the user credentials have been presented, the user is running "unlocked" and both `MATCH_DIRECT_BOOT_AWARE` and `MATCH_DIRECT_BOOT_UNAWARE` components are returned.

See also:

- `UserManager.isUserUnlocked()`

Constant Value: 262144 (0x00040000)

### MATCH_DISABLED_COMPONENTS

    public static final int MATCH_DISABLED_COMPONENTS

Constant Value: 512 (0x00000200)

### MATCH_DISABLED_UNTIL_USED_COMPONENTS

    public static final int MATCH_DISABLED_UNTIL_USED_COMPONENTS

`PackageInfo` flag: include disabled components which are in that state only because of `COMPONENT_ENABLED_STATE_DISABLED_UNTIL_USED` in the returned info. Note that if you set this flag, applications that are in this disabled state will be reported as enabled.

Constant Value: 32768 (0x00008000)

### MATCH_SYSTEM_ONLY

    public static final int MATCH_SYSTEM_ONLY

Querying flag: include only components from applications that are marked with `ApplicationInfo#FLAG_SYSTEM`.

Constant Value: 1048576 (0x00100000)

### MATCH_UNINSTALLED_PACKAGES

    public static final int MATCH_UNINSTALLED_PACKAGES

Flag parameter to retrieve some information about all applications (even uninstalled ones) which have data directories. This state could have resulted if applications have been deleted with flag `DELETE_KEEP_DATA` with a possibility of being replaced or reinstalled in future.

Note: this flag may cause less information about currently installed applications to be returned.

Note: use of this flag requires the android.permission.QUERY_ALL_PACKAGES permission to see uninstalled packages.

Constant Value: 8192 (0x00002000)

### MAXIMUM_VERIFICATION_TIMEOUT

    public static final long MAXIMUM_VERIFICATION_TIMEOUT

Can be used as the `millisecondsToDelay` argument for `PackageManager#extendVerificationTimeout`. This is the maximum time `PackageManager` waits for the verification agent to return (in milliseconds).

## Public constructors

### PackageManager

    public PackageManager ()

This constructor is deprecated.
Do not instantiate or subclass - obtain an instance from `Context#getPackageManager`

## Public methods

### addPackageToPreferred

    public abstract void addPackageToPreferred (String packageName)

This method is deprecated.
This function no longer does anything. It is the platform's responsibility to assign preferred activities and this cannot be modified directly. To determine the activities resolved by the platform, use `resolveActivity(Intent, int)` or `queryIntentActivities(Intent, int)`. To configure an app to be responsible for a particular role and to check current role holders, see `RoleManager`.

Parameters
`packageName` | `String`: This value cannot be `null`.

### addPermission

    public abstract boolean addPermission (PermissionInfo info)

Add a new dynamic permission to the system. For this to work, your package must have defined a permission tree through the `<permission-tree>` tag in its manifest. A package can only add permissions to trees that were defined by either its own package or another with the same user id; a permission is in a tree if it matches the name of the permission tree + ".": for example, "com.foo.bar" is a member of the permission tree "com.foo".

It is good to make your permission tree name descriptive, because you are taking possession of that entire set of permission names. Thus, it must be under a domain you control, with a suffix that will not match any normal permissions that may be declared in any applications that are part of that domain.

New permissions must be added before any .apks are installed that use those permissions. Permissions you add through this method are remembered across reboots of the device. If the given permission already exists, the info you supply here will be used to update it.

Parameters
`info` | `PermissionInfo`: Description of the permission to be added. This value cannot be `null`.

Returns
`boolean` | Returns true if a new permission was created, false if an existing one was updated.

Throws
`SecurityException` | if you are not allowed to add the given permission name.

See also:

- `removePermission(String)`

### addPermissionAsync

    public abstract boolean addPermissionAsync (PermissionInfo info)

Like `addPermission(android.content.pm.PermissionInfo)` but asynchronously persists the package manager state after returning from the call, allowing it to return quicker and batch a series of adds at the expense of no guarantee the added permission will be retained if the device is rebooted before it is written.

Parameters
`info` | `PermissionInfo`: This value cannot be `null`.

Returns
`boolean` |

### addPreferredActivity

    public abstract void addPreferredActivity (IntentFilter filter,
                    int match,
                    ComponentName[] set,
                    ComponentName activity)

This method is deprecated.
This function no longer does anything. It is the platform's responsibility to assign preferred activities and this cannot be modified directly. To determine the activities resolved by the platform, use `resolveActivity(Intent, int)` or `queryIntentActivities(Intent, int)`. To configure an app to be responsible for a particular role and to check current role holders, see `RoleManager`.

Add a new preferred activity mapping to the system. This will be used to automatically select the given activity component when `Context.startActivity()` finds multiple matching activities and also matches the given filter.

Parameters
`filter` | `IntentFilter`: The set of intents under which this activity will be made preferred. This value cannot be `null`.
`match` | `int`: The IntentFilter match category that this preference applies to.
`set` | `ComponentName`: The set of activities that the user was picking from when this preference was made. This value may be `null`.
`activity` | `ComponentName`: The component name of the activity that is to be preferred. This value cannot be `null`.

### addWhitelistedRestrictedPermission

    public boolean addWhitelistedRestrictedPermission (String packageName,
                    String permName,
                    int whitelistFlags)

Adds a whitelisted restricted permission for an app.

Permissions can be hard restricted which means that the app cannot hold them or soft restricted where the app can hold the permission but in a weaker form. Whether a permission is `restricted` or `soft restricted` depends on the permission declaration. Whitelisting a hard restricted permission allows for the to hold that permission and whitelisting a soft restricted permission allows the app to hold the permission in its full, unrestricted form.

There are four whitelists:
1. one for cases where the system permission policy whitelists a permission This list corresponds to the `FLAG_PERMISSION_WHITELIST_SYSTEM` flag. Can only be modified by pre-installed holders of a dedicated permission.
2. one for cases where the system whitelists the permission when upgrading from an OS version in which the permission was not restricted to an OS version in which the permission is restricted. This list corresponds to the `FLAG_PERMISSION_WHITELIST_UPGRADE` flag. Can be modified by pre-installed holders of a dedicated permission. The installer on record can only remove permissions from this whitelist.
3. one for cases where the installer of the package whitelists a permission. This list corresponds to the `FLAG_PERMISSION_WHITELIST_INSTALLER` flag. Can be modified by pre-installed holders of a dedicated permission or the installer on record.

You need to specify the whitelists for which to set the whitelisted permissions which will clear the previous whitelisted permissions and replace them with the provided ones.

Note: In retrospect it would have been preferred to use more inclusive terminology when naming this API. Similar APIs added will refrain from using the term "whitelist".

Parameters
`packageName` | `String`: The app for which to get whitelisted permissions. This value cannot be `null`.
`permName` | `String`: The whitelisted permission to add. This value cannot be `null`.

### canRequestPackageInstalls

    public abstract boolean canRequestPackageInstalls ()

Checks whether the calling package is allowed to request package installs through package installer. Apps are encouraged to call this API before launching the package installer via intent `Intent.ACTION_INSTALL_PACKAGE`. Starting from Android O, the user can explicitly choose what external sources they trust to install apps on the device. If this API returns false, the install request will be blocked by the package installer and a dialog will be shown to the user with an option to launch settings to change their preference. An application must target Android O or higher and declare permission `Manifest.permission.REQUEST_INSTALL_PACKAGES` in order to use this API.

Returns
`boolean` | true if the calling package is trusted by the user to request install packages on the device, false otherwise.

See also:

- `Intent.ACTION_INSTALL_PACKAGE`
- `Settings.ACTION_MANAGE_UNKNOWN_APP_SOURCES`

### checkSignatures

    public abstract int checkSignatures (String packageName1,
                    String packageName2)

Parameters
`packageName1` | `String`: First package name whose signature will be compared. This value cannot be `null`.
`packageName2` | `String`: Second package name whose signature will be compared. This value cannot be `null`.

Returns
`int` | Returns an integer indicating whether all signatures on the two packages match. The value is >= 0 (`SIGNATURE_MATCH`) if all signatures match or < 0 if there is not a match (`SIGNATURE_NO_MATCH` or `SIGNATURE_UNKNOWN_PACKAGE`). Value is `SIGNATURE_MATCH`, `SIGNATURE_NEITHER_SIGNED`, `SIGNATURE_FIRST_NOT_SIGNED`, `SIGNATURE_SECOND_NOT_SIGNED`, `SIGNATURE_NO_MATCH`, or `SIGNATURE_UNKNOWN_PACKAGE`

This can be useful, for example, when doing the check in an IPC, where the UID is the only identity available. It is functionally identical to determining the package associated with the UIDs and checking their signatures.

Parameters
`uid1` | `int`: First UID whose signature will be compared.
`uid2` | `int`: Second UID whose signature will be compared.

Returns
`int` | Returns an integer indicating whether all signatures on the two packages match.

To determine the activities resolved by the platform, use `resolveActivity(Intent, int)` or `queryIntentActivities(Intent, int)`. To configure an app to be responsible for a particular role and to check current role holders, see `RoleManager`.

Remove all preferred activity mappings, previously added with `addPreferredActivity(IntentFilter, int, ComponentName[], ComponentName)`, from the system whose activities are implemented in the given package name. An application can only clear its own package(s).

Parameters
`packageName` | `String`: The name of the package whose preferred activity mappings are to be removed. This value cannot be `null`.

Allows a package listening to the `broadcast` to extend the default timeout for a response and declare what action to perform after the timeout occurs. The response must include the `verificationCodeAtTimeout` which is one of `PackageManager#VERIFICATION_ALLOW` or `PackageManager#VERIFICATION_REJECT`. This method may only be called once per package id. Additional calls will have no effect.

Parameters
`id` | `int`: pending package identifier as passed via the `PackageManager#EXTRA_VERIFICATION_ID` Intent extra.
`verificationCodeAtTimeout` | `int`: either `PackageManager#VERIFICATION_ALLOW` or `PackageManager#VERIFICATION_REJECT`.

                    Rect badgeLocation,
                    int badgeDensity)

If the target user is a managed profile of the calling user or the caller is itself a managed profile, then this returns a badged copy of the given drawable allowing the user to distinguish it from the original drawable. The caller can specify the location in the bounds of the drawable to be badged where the badge should be applied as well as the density of the badge to be used.

If the original drawable is a BitmapDrawable and the backing bitmap is mutable as per `Bitmap.isMutable()`, the badging is performed in place and the original drawable is returned.

Parameters
`drawable` | `Drawable`: The drawable to badge. This value cannot be `null`.
`user` | `UserHandle`: The target user. This value cannot be `null`.
`badgeLocation` | `Rect`: Where in the bounds of the badged drawable to place the badge. If it's `null`, the badge is applied on top of the entire drawable being badged. This value may be `null`.
`badgeDensity` | `int`: The optional desired density for the badge as per `DisplayMetrics.densityDpi`. If it's not positive, the density of the display is used.

Returns
`Drawable` | A drawable that combines the original drawable and a badge as determined by the system.

### getUserBadgedIcon

    public abstract Drawable getUserBadgedIcon (Drawable drawable,
                    UserHandle user)

If the target user is a managed profile, then this returns a badged copy of the given icon to be able to distinguish it from the original icon. For badging an arbitrary drawable use `getUserBadgedDrawableForDensity(android.graphics.drawable.Drawable, android.os.UserHandle, android.graphics.Rect, int)`.

If the original drawable is a BitmapDrawable and the backing bitmap is mutable as per `Bitmap.isMutable()`, the badging is performed in place and the original drawable is returned.

Parameters
`drawable` | `Drawable`: The drawable to badge. This value cannot be `null`.
`user` | `UserHandle`: The target user. This value cannot be `null`.

Returns
`Drawable` | A drawable that combines the original icon and a badge as determined by the system. This value cannot be `null`.

Parameters
`label` | `CharSequence`: The label to change. This value cannot be `null`.
`user` | `UserHandle`: The target user. This value cannot be `null`.

Returns
`CharSequence` | A label that combines the original label and a badge as determined by the system. This value cannot be `null`.

### getWhitelistedRestrictedPermissions

    public Set<String> getWhitelistedRestrictedPermissions (String packageName,
                    int whitelistFlag)

Gets the restricted permissions that have been whitelisted and the app is allowed to have them granted in their full form.

Permissions can be hard restricted which means that the app cannot hold them or soft restricted where the app can hold the permission but in a weaker form. Whether a permission is `restricted` or `soft restricted` depends on the permission declaration. Whitelisting a hard restricted permission allows for the to hold that permission and whitelisting a soft restricted permission allows the app to hold the permission in its full, unrestricted form.

There are four allowlists:
1. one for cases where the system permission policy whitelists a permission This list corresponds to the`FLAG_PERMISSION_WHITELIST_SYSTEM` flag. Can only be accessed by pre-installed holders of a dedicated permission.
2. one for cases where the system whitelists the permission when upgrading from an OS version in which the permission was not restricted to an OS version in which the permission is restricted. This list corresponds to the `FLAG_PERMISSION_WHITELIST_UPGRADE` flag. Can be accessed by pre-installed holders of a dedicated permission or the installer on record.
3. one for cases where the installer of the package whitelists a permission. This list corresponds to the `FLAG_PERMISSION_WHITELIST_INSTALLER` flag. Can be accessed by pre-installed holders of a dedicated permission or the installer on record.

Note: In retrospect it would have been preferred to use more inclusive terminology when naming this API. Similar APIs added will refrain from using the term "whitelist".

Parameters
`packageName` | `String`: The app for which to get whitelisted permissions. This value cannot be `null`.
`whitelistFlag` | `int`: The flag to determine which whitelist to query. Only one flag can be passed.s Value is either `0` or a combination of `FLAG_PERMISSION_WHITELIST_SYSTEM`, `FLAG_PERMISSION_WHITELIST_INSTALLER`, and `FLAG_PERMISSION_WHITELIST_UPGRADE`

Returns
`Set<String>` | The whitelisted permissions that are on any of the whitelists you query for. This value cannot be `null`.

Throws
`SecurityException` | if you try to access a whitelist that you have no access to.

### getXml

    public abstract XmlResourceParser getXml (String packageName,
                    int resid,
                    ApplicationInfo appInfo)

Retrieve an XML file from a package. This is a low-level API used to retrieve XML meta data.

Parameters
`packageName` | `String`: The name of the package that this xml is coming from. Cannot be null. This value cannot be `null`.
`resid` | `int`: The resource identifier of the desired xml. Cannot be 0.
`appInfo` | `ApplicationInfo`: Overall information about packageName. This may be null, in which case the application information will be retrieved for you if needed; if you already have this information around, it can be much more efficient to supply it here. This value may be `null`.

Returns
`XmlResourceParser` | Returns an XmlPullParser allowing you to parse out the XML data. Returns null if the xml resource could not be found for any reason.

### hasSigningCertificate

    public boolean hasSigningCertificate (int uid,
                    byte[] certificate,
                    int type)

Searches the set of signing certificates by which the package(s) for the given uid has proven to have been signed. For multiple packages sharing the same uid, this will return the signing certificates found in the signing history of the "newest" package, where "newest" indicates the package with the newest signing certificate in the shared uid group. This method should be used instead of `getPackageInfo` with `GET_SIGNATURES` since it takes into account the possibility of signing certificate rotation, except in the case of packages that are signed by multiple certificates, for which signing certificate rotation is not supported. This method is analogous to using `getPackagesForUid` followed by `getPackageInfo` with `GET_SIGNING_CERTIFICATES`, selecting the `PackageInfo` of the newest-signed bpackage , and finally searching through the resulting `signingInfo` field to see if the desired certificate is there.

Parameters
`uid` | `int`: uid whose signing certificates to check
`certificate` | `byte`: signing certificate for which to search This value cannot be `null`.
`type` | `int`: representation of the `certificate` Value is `CERT_INPUT_RAW_X509`, or `CERT_INPUT_SHA256`

Returns
`boolean` | true if this package was or is signed by exactly the certificate `certificate`

### hasSigningCertificate

    public boolean hasSigningCertificate (String packageName,
                    byte[] certificate,
                    int type)

Searches the set of signing certificates by which the given package has proven to have been signed. This should be used instead of `getPackageInfo` with `GET_SIGNATURES` since it takes into account the possibility of signing certificate rotation, except in the case of packages that are signed by multiple certificates, for which signing certificate rotation is not supported. This method is analogous to using `getPackageInfo` with `GET_SIGNING_CERTIFICATES` and then searching through the resulting `signingInfo` field to see if the desired certificate is present.

Parameters
`packageName` | `String`: package whose signing certificates to check This value cannot be `null`.
`certificate` | `byte`: signing certificate for which to search This value cannot be `null`.
`type` | `int`: representation of the `certificate` Value is `CERT_INPUT_RAW_X509`, or `CERT_INPUT_SHA256`

`version` | `int`

Returns
`boolean` | Returns true if the devices supports the feature, else false.

### isAutoRevokeWhitelisted

Note: In retrospect it would have been preferred to use more inclusive terminology when naming this API. Similar APIs added will refrain from using the term "whitelist".

Parameters
`packageName` | `String`: The app for which to set exemption. This value cannot be `null`.

Returns
`boolean` | Whether the app is whitelisted.

Throws
`PackageManager.NameNotFoundException` | if the package could not be found.

See also:

- `isPackageSuspended()`

### isPackageSuspended

    public boolean isPackageSuspended ()

Apps can query this to know if they have been suspended. A system app with the permission `android.permission.SUSPEND_APPS` can put any app on the device into a suspended state.

While in this state, the application's notifications will be hidden, any of its started activities will be stopped and it will not be able to show toasts or dialogs or play audio. When the user tries to launch a suspended app, the system will, instead, show a dialog to the user informing them that they cannot use this app while it is suspended.

When an app is put into this state, the broadcast action `Intent#ACTION_MY_PACKAGE_SUSPENDED` will be delivered to any of its broadcast receivers that included this action in their intent-filters, including manifest receivers. Similarly, a broadcast action `Intent#ACTION_MY_PACKAGE_UNSUSPENDED` is delivered when a previously suspended app is taken out of this state. Apps are expected to use these to gracefully deal with transitions to and from this state.

Returns
`boolean` | `true` if the calling package has been suspended, `false` otherwise.

See also:

- `getSuspendedPackageAppExtras()`
- `Intent.ACTION_MY_PACKAGE_SUSPENDED`
- `Intent.ACTION_MY_PACKAGE_UNSUSPENDED`

### removeWhitelistedRestrictedPermission

    public boolean removeWhitelistedRestrictedPermission (String packageName,
                    String permName,

Removes a whitelisted restricted permission for an app.

Permissions can be hard restricted which means that the app cannot hold them or soft restricted where the app can hold the permission but in a weaker form. Whether a permission is `restricted` or `soft restricted` depends on the permission declaration. Whitelisting a hard restricted permission allows for the to hold that permission and whitelisting a soft restricted permission allows the app to hold the permission in its full, unrestricted form.

There are four whitelists:
1. one for cases where the system permission policy whitelists a permission This list corresponds to the `FLAG_PERMISSION_WHITELIST_SYSTEM` flag. Can only be modified by pre-installed holders of a dedicated permission.
2. one for cases where the system whitelists the permission when upgrading from an OS version in which the permission was not restricted to an OS version in which the permission is restricted. This list corresponds to the `FLAG_PERMISSION_WHITELIST_UPGRADE` flag. Can be modified by pre-installed holders of a dedicated permission. The installer on record can only remove permissions from this whitelist.
3. one for cases where the installer of the package whitelists a permission. This list corresponds to the `FLAG_PERMISSION_WHITELIST_INSTALLER` flag. Can be modified by pre-installed holders of a dedicated permission or the installer on record.
4. one for cases where the system exempts the permission when upgrading from an OS version in which the permission was not restricted to an OS version in which the permission is restricted. This list corresponds to the `FLAG_PERMISSION_WHITELIST_UPGRADE` flag. Can be modified by pre-installed holders of a dedicated permission. The installer on record can only remove permissions from this allowlist.

You need to specify the whitelists for which to set the whitelisted permissions which will clear the previous whitelisted permissions and replace them with the provided ones.

Note: In retrospect it would have been preferred to use more inclusive terminology when naming this API. Similar APIs added will refrain from using the term "whitelist".

Parameters
`packageName` | `String`: The app for which to get whitelisted permissions. This value cannot be `null`.
`permName` | `String`: The whitelisted permission to remove. This value cannot be `null`.
`whitelistFlags` | `int`: The whitelists from which to remove. Passing multiple flags updates all specified whitelists. Value is either `0` or a combination of `FLAG_PERMISSION_WHITELIST_SYSTEM`, `FLAG_PERMISSION_WHITELIST_INSTALLER`, and `FLAG_PERMISSION_WHITELIST_UPGRADE`

Returns
`boolean` | Whether the permission was removed from the whitelist.

Throws
`SecurityException` | if you try to modify a whitelist that you have no access to.

### requestChecksums

    public void requestChecksums (String packageName,
                    boolean includeSplits,
                    int required,
                    List<Certificate> trustedInstallers,
                    PackageManager.OnChecksumsReadyListener onChecksumsReadyListener)

Requesting the checksums for APKs within a package. The checksums will be returned asynchronously via onChecksumsReadyListener. By default returns all readily available checksums: - enforced by platform, - enforced by installer. If caller needs a specific checksum kind, they can specify it as required. Caution: Android can not verify installer-provided checksums. Make sure you specify trusted installers.

Parameters
`packageName` | `String`: whose checksums to return. This value cannot be `null`.
`includeSplits` | `boolean`: whether to include checksums for non-base splits.
`required` | `int`: explicitly request the checksum types. May incur significant CPU/memory/disk usage. Value is either `0` or a combination of `Checksum.TYPE_WHOLE_MERKLE_ROOT_4K_SHA256`, `Checksum.TYPE_WHOLE_MD5`, `Checksum.TYPE_WHOLE_SHA1`, `Checksum.TYPE_WHOLE_SHA256`, `Checksum.TYPE_WHOLE_SHA512`, `Checksum.TYPE_PARTIAL_MERKLE_ROOT_1M_SHA256`, and `Checksum.TYPE_PARTIAL_MERKLE_ROOT_1M_SHA512`
`trustedInstallers` | `List`: for checksums enforced by installer, which installers are to be trusted. `TRUST_ALL` will return checksums from any installer, `TRUST_NONE` disables optimized installer-enforced checksums, otherwise the list has to be non-empty list of certificates. This value cannot be `null`.
`onChecksumsReadyListener` | `PackageManager.OnChecksumsReadyListener`: called once when the results are available. This value cannot be `null`.

Throws
`CertificateEncodingException` | if an encoding error occurs for trustedInstallers.
`IllegalArgumentException` | if the list of trusted installer certificates is empty.
`PackageManager.NameNotFoundException` | if a package with the given name cannot be found on the system.

### resolveActivity

    public abstract ResolveInfo resolveActivity (Intent intent,
                    int flags)

Determine the best action to perform for a given Intent. This is how `Intent#resolveActivity` finds an activity if a class has not been explicitly specified.

Note: if using an implicit Intent (without an explicit ComponentName specified), be sure to consider whether to set the `MATCH_DEFAULT_ONLY` only flag. You need to do so to resolve the activity in the same way that `Context.startActivity(Intent)` and `Intent.resolveActivity(PackageManager)` do.

Parameters
`intent` | `Intent`: An intent containing all of the desired specification (action, data, type, category, and/or component). This value cannot be `null`.
`flags` | `int`: Additional option flags to modify the data returned. The most important is `MATCH_DEFAULT_ONLY`, to limit the resolution to only those activities that support the `Intent.CATEGORY_DEFAULT`. Value is either `0` or a combination of `GET_META_DATA`, `GET_RESOLVED_FILTER`, `GET_SHARED_LIBRARY_FILES`, `MATCH_ALL`, android.content.pm.PackageManager.MATCH_DEBUG_TRIAGED_MISSING, `MATCH_DISABLED_COMPONENTS`, `MATCH_DISABLED_UNTIL_USED_COMPONENTS`, `MATCH_DEFAULT_ONLY`, `MATCH_DIRECT_BOOT_AUTO`, `MATCH_DIRECT_BOOT_AWARE`, `MATCH_DIRECT_BOOT_UNAWARE`, `MATCH_SYSTEM_ONLY`, `MATCH_UNINSTALLED_PACKAGES`, android.content.pm.PackageManager.MATCH_INSTANT, `GET_DISABLED_COMPONENTS`, `GET_DISABLED_UNTIL_USED_COMPONENTS`, and `GET_UNINSTALLED_PACKAGES`

Returns
`ResolveInfo` | Returns a ResolveInfo object containing the final activity intent that was determined to be the best action. Returns null if no matching activity was found. If multiple matching activities are found and there is no default set, returns a ResolveInfo object containing something else, such as the activity resolver.

### resolveContentProvider

    public abstract ProviderInfo resolveContentProvider (String authority,
                    int flags)

Find a single content provider by its authority.

Example:

Parameters
`authority` | `String`: The authority of the provider to find. This value cannot be `null`.
`flags` | `int`: Additional option flags to modify the data returned. Value is either `0` or a combination of `GET_META_DATA`, `GET_SHARED_LIBRARY_FILES`, `MATCH_ALL`, android.content.pm.PackageManager.MATCH_DEBUG_TRIAGED_MISSING, `MATCH_DEFAULT_ONLY`, `MATCH_DISABLED_COMPONENTS`, `MATCH_DISABLED_UNTIL_USED_COMPONENTS`, `MATCH_DIRECT_BOOT_AUTO`, `MATCH_DIRECT_BOOT_AWARE`, `MATCH_DIRECT_BOOT_UNAWARE`, `MATCH_SYSTEM_ONLY`, `MATCH_UNINSTALLED_PACKAGES`, android.content.pm.PackageManager.MATCH_INSTANT, android.content.pm.PackageManager.MATCH_STATIC_SHARED_LIBRARIES, `GET_DISABLED_COMPONENTS`, `GET_DISABLED_UNTIL_USED_COMPONENTS`, and `GET_UNINSTALLED_PACKAGES`

Returns
`ProviderInfo` | A `ProviderInfo` object containing information about the provider. If a provider was not found, returns null.

### resolveService

    public abstract ResolveInfo resolveService (Intent intent,
                    int flags)

Determine the best service to handle for a given Intent.

Parameters
`intent` | `Intent`: An intent containing all of the desired specification (action, data, type, category, and/or component). This value cannot be `null`.
`flags` | `int`: Additional option flags to modify the data returned. Value is either `0` or a combination of `GET_META_DATA`, `GET_RESOLVED_FILTER`, `GET_SHARED_LIBRARY_FILES`, `MATCH_ALL`, android.content.pm.PackageManager.MATCH_DEBUG_TRIAGED_MISSING, `MATCH_DISABLED_COMPONENTS`, `MATCH_DISABLED_UNTIL_USED_COMPONENTS`, `MATCH_DEFAULT_ONLY`, `MATCH_DIRECT_BOOT_AUTO`, `MATCH_DIRECT_BOOT_AWARE`, `MATCH_DIRECT_BOOT_UNAWARE`, `MATCH_SYSTEM_ONLY`, `MATCH_UNINSTALLED_PACKAGES`, android.content.pm.PackageManager.MATCH_INSTANT, `GET_DISABLED_COMPONENTS`, `GET_DISABLED_UNTIL_USED_COMPONENTS`, and `GET_UNINSTALLED_PACKAGES`

### setApplicationCategoryHint

    public abstract void setApplicationCategoryHint (String packageName,
                    int categoryHint)

Provide a hint of what the `ApplicationInfo#category` value should be for the given package.

This hint can only be set by the app which installed this package, as determined by `getInstallerPackageName(java.lang.String)`.

Parameters
`packageName` | `String`: the package to change the category hint for. This value cannot be `null`.
`categoryHint` | `int`: the category hint to set. Value is `ApplicationInfo.CATEGORY_UNDEFINED`, `ApplicationInfo.CATEGORY_GAME`, `ApplicationInfo.CATEGORY_AUDIO`, `ApplicationInfo.CATEGORY_VIDEO`, `ApplicationInfo.CATEGORY_IMAGE`, `ApplicationInfo.CATEGORY_SOCIAL`, `ApplicationInfo.CATEGORY_NEWS`, `ApplicationInfo.CATEGORY_MAPS`, `ApplicationInfo.CATEGORY_PRODUCTIVITY`, or `ApplicationInfo.CATEGORY_ACCESSIBILITY`

### setApplicationEnabledSetting

    public abstract void setApplicationEnabledSetting (String packageName,
                    int newState,
                    int flags)

Set the enabled setting for an application This setting will override any enabled state which may have been set by the application in its manifest. It also overrides the enabled state set in the manifest for any of the application's components. It does not override any enabled state set by `setComponentEnabledSetting(ComponentName, int, int)` for any of the application's components.

Parameters
`packageName` | `String`: The package name of the application to enable This value cannot be `null`.
`newState` | `int`: The new enabled state for the application. Value is `COMPONENT_ENABLED_STATE_DEFAULT`, `COMPONENT_ENABLED_STATE_ENABLED`, `COMPONENT_ENABLED_STATE_DISABLED`, `COMPONENT_ENABLED_STATE_DISABLED_USER`, or `COMPONENT_ENABLED_STATE_DISABLED_UNTIL_USED`

### setAutoRevokeWhitelisted

    public boolean setAutoRevokeWhitelisted (String packageName,
                    boolean whitelisted)

Marks an application exempt from having its permissions be automatically revoked when the app is unused for an extended period of time. Only the installer on record that installed the given package is allowed to call this. Packages start in whitelisted state, and it is the installer's responsibility to un-whitelist the packages it installs, unless auto-revoking permissions from that package would cause breakages beyond having to re-request the permission(s).

Note: In retrospect it would have been preferred to use more inclusive terminology when naming this API. Similar APIs added will refrain from using the term "whitelist".

Parameters
`packageName` | `String`: The app for which to set exemption. This value cannot be `null`.
`whitelisted` | `boolean`: Whether the app should be whitelisted.

Returns
`boolean` | whether any change took effect.

Throws
`SecurityException` | if you you have no access to modify this.

See also:

- `isAutoRevokeWhitelisted()`

### setComponentEnabledSetting

    public abstract void setComponentEnabledSetting (ComponentName componentName,
                    int newState,
                    int flags)

Set the enabled setting for a package component (activity, receiver, service, provider). This setting will override any enabled state which may have been set by the component in its manifest.

Parameters
`componentName` | `ComponentName`: The component to enable This value cannot be `null`.
`newState` | `int`: The new enabled state for the component. Value is `COMPONENT_ENABLED_STATE_DEFAULT`, `COMPONENT_ENABLED_STATE_ENABLED`, `COMPONENT_ENABLED_STATE_DISABLED`, `COMPONENT_ENABLED_STATE_DISABLED_USER`, or `COMPONENT_ENABLED_STATE_DISABLED_UNTIL_USED`
`flags` | `int`: Optional behavior flags. Value is either `0` or a combination of `DONT_KILL_APP`, and `SYNCHRONOUS`

### setInstallerPackageName

    public abstract void setInstallerPackageName (String targetPackage,
                    String installerPackageName)

Change the installer associated with a given package. There are limitations on how the installer package can be changed; in particular:

- A SecurityException will be thrown if installerPackageName is not signed with the same certificate as the calling application.
- A SecurityException will be thrown if targetPackage already has an installer package, and that installer package is not signed with the same certificate as the calling application.

Parameters
`targetPackage` | `String`: The installed package whose installer will be changed. This value cannot be `null`.
`installerPackageName` | `String`: The package name of the new installer. May be null to clear the association. This value may be `null`.

### setMimeGroup

    public void setMimeGroup (String mimeGroup,
                    Set<String> mimeTypes)

Sets MIME group's MIME types. Libraries should use a reverse-DNS prefix followed by a ':' character and library-specific group name to avoid namespace collisions, e.g. "com.example:myFeature".

Parameters
`mimeGroup` | `String`: MIME group to modify. This value cannot be `null`.
`mimeTypes` | `Set`: new MIME types contained by MIME group. This value cannot be `null`.

Throws
`IllegalArgumentException` | if the MIME group was not declared in the manifest.

### updateInstantAppCookie

    public abstract void updateInstantAppCookie (byte[] cookie)

Updates the instant application cookie for the calling app. Non instant apps and apps that were instant but were upgraded to normal apps can still access this API. For instant apps this cookie is cached for some time after uninstall while for normal apps the cookie is deleted after the app is uninstalled. The cookie is always present while the app is installed. The cookie size is limited by `getInstantAppCookieMaxBytes()`. Passing `null` or an empty array clears the cookie.

Parameters
`cookie` | `byte`: The cookie data. This value may be `null`.

Throws
`IllegalArgumentException` | if the array exceeds max cookie size.

- `isInstantApp()`
- `isInstantApp(String)`
- `getInstantAppCookieMaxBytes()`
- `getInstantAppCookie()`
- `clearInstantAppCookie()`

### verifyPendingInstall

    public abstract void verifyPendingInstall (int id,
                    int verificationCode)

Allows a package listening to the `broadcast` to respond to the package manager. The response must include the `verificationCode` which is one of `PackageManager#VERIFICATION_ALLOW` or `PackageManager#VERIFICATION_REJECT`.

Parameters
`id` | `int`: pending package identifier as passed via the `PackageManager#EXTRA_VERIFICATION_ID` Intent extra.
`verificationCode` | `int`: either `PackageManager#VERIFICATION_ALLOW` or `PackageManager#VERIFICATION_REJECT`.

Throws
`SecurityException` | if the caller does not have the PACKAGE_VERIFICATION_AGENT permission.
