`public static final class AppUriAuthenticationPolicy.Builder`
`extends Object` ``

java.lang.Object
↳ | android.security.AppUriAuthenticationPolicy.Builder

Builder class for `AppUriAuthenticationPolicy` objects.

## Summary

### Public constructors
`Builder()` Initialize a new Builder to construct an `AppUriAuthenticationPolicy`.

### Public methods
`AppUriAuthenticationPolicy.Builder` | `addAppAndUriMapping(String appPackageName, Uri uri, String alias)` Adds mappings from an app and URI to an alias, which will be used for authentication.
`AppUriAuthenticationPolicy` | `build()` Combines all of the attributes that have been set on the `Builder`

### Inherited methods
From class `java.lang.Object`
`Object` | `clone()` Creates and returns a copy of this object.
`boolean` | `equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void` | `finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>` | `getClass()` Returns the runtime class of this `Object`.
`int` | `hashCode()` Returns a hash code value for the object.
`final void` | `notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void` | `notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String` | `toString()` Returns a string representation of the object.
`final void` | `wait(long timeout, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void` | `wait(long timeout)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void` | `wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.

## Public constructors

### Builder

    public Builder ()

Initialize a new Builder to construct an `AppUriAuthenticationPolicy`.

## Public methods

### addAppAndUriMapping

    public AppUriAuthenticationPolicy.Builder addAppAndUriMapping (String appPackageName,
                    Uri uri,
                    String alias)

Adds mappings from an app and URI to an alias, which will be used for authentication.

If this method is called with a package name and URI that was previously added, the previous alias will be overwritten.

When the system tries to determine which alias to return to a requesting app calling `KeyChain.choosePrivateKeyAlias`, it will choose the alias whose associated URI exactly matches the URI provided in `KeyChain#choosePrivateKeyAlias( Activity, KeyChainAliasCallback, String[], Principal[], Uri, String)` or the URI built from the host and port provided in `KeyChain#choosePrivateKeyAlias( Activity, KeyChainAliasCallback, String[], Principal[], String, int, String)`.

Parameters
`appPackageName` | `String`: The app's package name to authenticate the user to. This value cannot be `null`.
`uri` | `Uri`: The URI to authenticate the user to. This value cannot be `null`.
`alias` | `String`: The alias which will be used for authentication. This value cannot be `null`.

Returns
`AppUriAuthenticationPolicy.Builder` | the same Builder instance. This value cannot be `null`.

### build

    public AppUriAuthenticationPolicy build ()

Combines all of the attributes that have been set on the `Builder`

Returns
`AppUriAuthenticationPolicy` | a new `AppUriAuthenticationPolicy` object. This value cannot be `null`.
