# TelecomManager

`public class TelecomManager`
`extends Object` ``

java.lang.Object
↳ | android.telecom.TelecomManager

Provides access to information about active calls and registration/call-management functionality. Apps can use methods in this class to determine the current call state.

Apps do not instantiate this class directly; instead, they retrieve a reference to an instance through `Context.getSystemService(Context.TELECOM_SERVICE)`.

Note that access to some telecom information is permission-protected. Your app cannot access the protected information or gain access to protected functionality unless it has the appropriate permissions declared in its manifest file. Where permissions apply, they are noted in the method descriptions.

    public static final String EXTRA_START_CALL_WITH_RTT

A boolean extra, which when set on the `Intent#ACTION_CALL` intent or on the bundle passed into `placeCall(android.net.Uri, android.os.Bundle)`, indicates that the call should be initiated with an RTT session open. See `Call.RttCall` for more information on RTT.

Constant Value: "android.telecom.extra.START_CALL_WITH_RTT"

### EXTRA_START_CALL_WITH_SPEAKERPHONE

    public static final String EXTRA_START_CALL_WITH_SPEAKERPHONE

Optional extra for `Intent.ACTION_CALL` containing a boolean that determines whether the speakerphone should be automatically turned on for an outgoing call.

Constant Value: "android.telecom.extra.START_CALL_WITH_SPEAKERPHONE"

### EXTRA_START_CALL_WITH_VIDEO_STATE

    public static final String EXTRA_START_CALL_WITH_VIDEO_STATE

Optional extra for `Intent.ACTION_CALL` containing an integer that determines the desired video state for an outgoing call. Valid options: `VideoProfile#STATE_AUDIO_ONLY`, `VideoProfile#STATE_BIDIRECTIONAL`, `VideoProfile#STATE_RX_ENABLED`, `VideoProfile#STATE_TX_ENABLED`.

Constant Value: "android.telecom.extra.START_CALL_WITH_VIDEO_STATE"

### EXTRA_USE_ASSISTED_DIALING

    public static final String EXTRA_USE_ASSISTED_DIALING

The boolean indicated by this extra controls whether or not a call is eligible to undergo assisted dialing. This extra is stored under `EXTRA_OUTGOING_CALL_EXTRAS`.

The call initiator can use this extra to indicate that a call used assisted dialing to help place the call. This is most commonly used by a Dialer app which provides the ability to automatically add dialing prefixes when placing international calls.

Setting this extra on the outgoing call extras will cause the `Connection#PROPERTY_ASSISTED_DIALING` property and `Call.Details#PROPERTY_ASSISTED_DIALING` property to be set on the `Connection`/`Call` in question. When the call is logged to the call log, the `CallLog.Calls.FEATURES_ASSISTED_DIALING_USED` call feature is set to indicate that assisted dialing was used for the call.

Constant Value: "android.telecom.extra.USE_ASSISTED_DIALING"

### GATEWAY_ORIGINAL_ADDRESS

    public static final String GATEWAY_ORIGINAL_ADDRESS

An optional `Intent.ACTION_CALL` intent extra corresponding to the original address to dial for the call. This is used when an alternative gateway address is provided to recall the original address. The value is a `Uri`. (See `GATEWAY_PROVIDER_PACKAGE` for details)

Constant Value: "android.telecom.extra.GATEWAY_ORIGINAL_ADDRESS"

### GATEWAY_PROVIDER_PACKAGE

    public static final String GATEWAY_PROVIDER_PACKAGE

An optional `Intent.ACTION_CALL` intent extra denoting the package name of the app specifying an alternative gateway for the call. The value is a string. (The following comment corresponds to the all GATEWAY_* extras) An app which sends the `Intent.ACTION_CALL` intent can specify an alternative address to dial which is different from the one specified and displayed to the user. This alternative address is referred to as the gateway address.

Constant Value: "android.telecom.extra.GATEWAY_PROVIDER_PACKAGE"

### METADATA_INCLUDE_EXTERNAL_CALLS

    public static final String METADATA_INCLUDE_EXTERNAL_CALLS

A boolean meta-data value indicating whether an `InCallService` wants to be informed of calls which have the `Call.Details#PROPERTY_IS_EXTERNAL_CALL` property. An external call is one which a `ConnectionService` knows about, but is not connected to directly. Dialer implementations (see `getDefaultDialerPackage()`) which would like to be informed of external calls should set this meta-data to `true` in the manifest registration of their `InCallService`. By default, the `InCallService` will NOT be informed of external calls.

Constant Value: "android.telecom.INCLUDE_EXTERNAL_CALLS"

### METADATA_INCLUDE_SELF_MANAGED_CALLS

    public static final String METADATA_INCLUDE_SELF_MANAGED_CALLS

A boolean meta-data value indicating whether an `InCallService` wants to be informed of calls which have the `Call.Details#PROPERTY_SELF_MANAGED` property. A self-managed call is one which originates from a self-managed `ConnectionService` which has chosen to implement its own call user interface. An `InCallService` implementation which would like to be informed of external calls should set this meta-data to `true` in the manifest registration of their `InCallService`. By default, the `InCallService` will NOT be informed about self-managed calls.

An `InCallService` which receives self-managed calls is free to view and control the state of calls in the self-managed `ConnectionService`. An example use-case is exposing these calls to an automotive device via its companion app.

This meta-data can only be set for an `InCallService` which also sets `METADATA_IN_CALL_SERVICE_UI`. Only the default phone/dialer app, or a car-mode `InCallService` can see self-managed calls.

See also `Connection#PROPERTY_SELF_MANAGED`.

Constant Value: "android.telecom.INCLUDE_SELF_MANAGED_CALLS"

### METADATA_IN_CALL_SERVICE_CAR_MODE_UI

    public static final String METADATA_IN_CALL_SERVICE_CAR_MODE_UI

### METADATA_IN_CALL_SERVICE_UI

    public static final String METADATA_IN_CALL_SERVICE_UI

A boolean meta-data value indicating whether an `InCallService` implements an in-call user interface. Dialer implementations (see `getDefaultDialerPackage()`) which would also like to replace the in-call interface should set this meta-data to `true` in the manifest registration of their `InCallService`.

Constant Value: "android.telecom.IN_CALL_SERVICE_UI"

### PRESENTATION_ALLOWED

    public static final int PRESENTATION_ALLOWED

Indicates that the address or number of a call is allowed to be displayed for caller ID.

Constant Value: 1 (0x00000001)

## Public methods

### acceptHandover

    public void acceptHandover (Uri srcAddr,
                    int videoState,
                    PhoneAccountHandle destAcct)

Called by an app to indicate that it wishes to accept the handover of an ongoing call to a `PhoneAccountHandle` it defines.

A call handover is the process where an ongoing call is transferred from one app (i.e. `ConnectionService` to another app. The user could, for example, choose to continue a mobile network call in a video calling app. The mobile network call via the Telephony stack is referred to as the source of the handover, and the video calling app is referred to as the destination.

When considering a handover scenario the initiating device is where a user initiated the handover process (e.g. by calling `Call.handoverTo(PhoneAccountHandle, int, Bundle)`, and the other device is considered the receiving device.

For a full discussion of the handover process and the APIs involved, see `Call.handoverTo(PhoneAccountHandle, int, Bundle)`.

This method is called from the receiving side of a handover to indicate a desire to accept the handover of an ongoing call to another `ConnectionService` identified by `PhoneAccountHandle` destAcct. For managed `ConnectionService`s, the specified `PhoneAccountHandle` must have been registered with `registerPhoneAccount(PhoneAccount)` and the user must have enabled the corresponding `PhoneAccount`. This can be checked using `getPhoneAccount(PhoneAccountHandle)`. Self-managed `ConnectionService`s must have `Manifest.permission.MANAGE_OWN_CALLS` to handover a call to it.

Once invoked, this method will cause the system to bind to the `ConnectionService` associated with the `PhoneAccountHandle` destAcct and call (See `ConnectionService#onCreateIncomingHandoverConnection`).

For a managed `ConnectionService`, a `SecurityException` will be thrown if either the `PhoneAccountHandle` destAcct does not correspond to a registered `PhoneAccount` or the associated `PhoneAccount` is not currently enabled by the user.

For a self-managed `ConnectionService`, a `SecurityException` will be thrown if the calling app does not have `Manifest.permission.MANAGE_OWN_CALLS`.

Parameters
`srcAddr` | `Uri`: The `Uri` of the ongoing call to handover to the caller’s `ConnectionService`.
`videoState` | `int`: Video state after the handover. Value is either `0` or a combination of `VideoProfile.STATE_AUDIO_ONLY`, `VideoProfile.STATE_TX_ENABLED`, `VideoProfile.STATE_RX_ENABLED`, `VideoProfile.STATE_BIDIRECTIONAL`, and `VideoProfile.STATE_PAUSED`
`destAcct` | `PhoneAccountHandle`: The `PhoneAccountHandle` registered to the calling package.

### acceptRingingCall

    public void acceptRingingCall (int videoState)

This method is deprecated.
Companion apps for wearable devices should use the `InCallService` API instead.

If there is a ringing incoming call, this method accepts the call on behalf of the user, with the specified video state.
Requires `Manifest.permission.ANSWER_PHONE_CALLS` or `Manifest.permission.MODIFY_PHONE_STATE`

Parameters
`videoState` | `int`: The desired video state to answer the call with.

### acceptRingingCall

    public void acceptRingingCall ()

This method is deprecated.
Companion apps for wearable devices should use the `InCallService` API instead.

If there is a ringing incoming call, this method accepts the call on behalf of the user. If the incoming call is a video call, the call will be answered with the same video state as the incoming call requests. This means, for example, that an incoming call requesting `VideoProfile#STATE_BIDIRECTIONAL` will be answered, accepting that state.
Requires `Manifest.permission.ANSWER_PHONE_CALLS` or `Manifest.permission.MODIFY_PHONE_STATE`

### addNewIncomingCall

    public void addNewIncomingCall (PhoneAccountHandle phoneAccount,
                    Bundle extras)

Registers a new incoming call. A `ConnectionService` should invoke this method when it has an incoming call. For managed `ConnectionService`s, the specified `PhoneAccountHandle` must have been registered with `registerPhoneAccount(PhoneAccount)` and the user must have enabled the corresponding `PhoneAccount`. This can be checked using `getPhoneAccount(PhoneAccountHandle)`. Self-managed `ConnectionService`s must have `Manifest.permission.MANAGE_OWN_CALLS` to add a new incoming call.

The incoming call you are adding is assumed to have a video state of `VideoProfile#STATE_AUDIO_ONLY`, unless the extra value `EXTRA_INCOMING_VIDEO_STATE` is specified.

Once invoked, this method will cause the system to bind to the `ConnectionService` associated with the `PhoneAccountHandle` and request additional information about the call (See `ConnectionService#onCreateIncomingConnection`) before starting the incoming call UI.

For a managed `ConnectionService`, a `SecurityException` will be thrown if either the `PhoneAccountHandle` does not correspond to a registered `PhoneAccount` or the associated `PhoneAccount` is not currently enabled by the user.

For a self-managed `ConnectionService`, a `SecurityException` will be thrown if the `PhoneAccount` has `PhoneAccount#CAPABILITY_SELF_MANAGED` and the calling app does not have `Manifest.permission.MANAGE_OWN_CALLS`.

Parameters
`phoneAccount` | `PhoneAccountHandle`: A `PhoneAccountHandle` registered with `registerPhoneAccount(PhoneAccount)`.
`extras` | `Bundle`: A bundle that will be passed through to `ConnectionService#onCreateIncomingConnection`.

### addNewIncomingConference

    public void addNewIncomingConference (PhoneAccountHandle phoneAccount,
                    Bundle extras)

Registers a new incoming conference. A `ConnectionService` should invoke this method when it has an incoming conference. An incoming `Conference` is an adhoc conference call initiated on another device which the user is being invited to join in. For managed `ConnectionService`s, the specified `PhoneAccountHandle` must have been registered with `registerPhoneAccount(PhoneAccount)` and the user must have enabled the corresponding `PhoneAccount`. This can be checked using `getPhoneAccount(android.telecom.PhoneAccountHandle)`. Self-managed `ConnectionService`s must have `Manifest.permission.MANAGE_OWN_CALLS` to add a new incoming call.

The incoming conference you are adding is assumed to have a video state of `VideoProfile#STATE_AUDIO_ONLY`, unless the extra value `EXTRA_INCOMING_VIDEO_STATE` is specified.

Once invoked, this method will cause the system to bind to the `ConnectionService` associated with the `PhoneAccountHandle` and request additional information about the call (See `ConnectionService#onCreateIncomingConference(PhoneAccountHandle, ConnectionRequest)`) before starting the incoming call UI.

For a managed `ConnectionService`, a `SecurityException` will be thrown if either the `PhoneAccountHandle` does not correspond to a registered `PhoneAccount` or the associated `PhoneAccount` is not currently enabled by the user.

Parameters
`phoneAccount` | `PhoneAccountHandle`: A `PhoneAccountHandle` registered with `registerPhoneAccount(PhoneAccount)`. This value cannot be `null`.

### placeCall

    public void placeCall (Uri address,
                    Bundle extras)

Places a new outgoing call to the provided address using the system telecom service with the specified extras. This method is equivalent to placing an outgoing call using `Intent#ACTION_CALL`, except that the outgoing call will always be sent via the system telecom service. If method-caller is either the user selected default dialer app or preloaded system dialer app, then emergency calls will also be allowed. Placing a call via a managed `ConnectionService` requires permission: `Manifest.permission.CALL_PHONE` Usage example:

     Uri uri = Uri.fromParts("tel", "12345", null);
     Bundle extras = new Bundle();
     extras.putBoolean(TelecomManager.EXTRA_START_CALL_WITH_SPEAKERPHONE, true);
     telecomManager.placeCall(uri, extras);

The following keys are supported in the supplied extras.

- `EXTRA_OUTGOING_CALL_EXTRAS`
- `EXTRA_PHONE_ACCOUNT_HANDLE`
- `EXTRA_START_CALL_WITH_SPEAKERPHONE`
- `EXTRA_START_CALL_WITH_VIDEO_STATE`

An app which implements the self-managed `ConnectionService` API uses `placeCall(android.net.Uri, android.os.Bundle)` to inform Telecom of a new outgoing call. A self-managed `ConnectionService` must include `EXTRA_PHONE_ACCOUNT_HANDLE` to specify its associated `PhoneAccountHandle`. Self-managed `ConnectionService`s require permission `Manifest.permission.MANAGE_OWN_CALLS`.

Note: If this method is used to place an emergency call, it is not guaranteed that the call will be placed on the `PhoneAccount` provided in the `EXTRA_PHONE_ACCOUNT_HANDLE` extra (if specified) and may be placed on another `PhoneAccount` with the `PhoneAccount#CAPABILITY_PLACE_EMERGENCY_CALLS` capability, depending on external factors, such as network conditions and Modem/SIM status.

Requires `Manifest.permission.CALL_PHONE` or `Manifest.permission.MANAGE_OWN_CALLS`

Parameters
`address` | `Uri`: The address to make the call to.
`extras` | `Bundle`: Bundle of extras to use with the call.

### registerPhoneAccount

    public void registerPhoneAccount (PhoneAccount account)

Register a `PhoneAccount` for use by the system that will be stored in Device Encrypted storage. When registering `PhoneAccount`s, existing registrations will be overwritten if the `PhoneAccountHandle` matches that of a `PhoneAccount` which is already registered. Once registered, the `PhoneAccount` is listed to the user as an option when placing calls. The user may still need to enable the `PhoneAccount` within the phone app settings before the account is usable.

A `SecurityException` will be thrown if an app tries to register a `PhoneAccountHandle` where the package name specified within `PhoneAccountHandle#getComponentName()` does not match the package name of the app.

Parameters
`account` | `PhoneAccount`: The complete `PhoneAccount`.

### showInCallScreen

    public void showInCallScreen (boolean showDialpad)

Parameters
`showDialpad` | `boolean`: Brings up the in-call dialpad as part of showing the in-call screen.

### silenceRinger

    public void silenceRinger ()

Silences the ringer if a ringing call exists.

This method can only be relied upon to stop the ringtone for a call if the ringtone has already started playing. It is intended to handle use-cases such as silencing a ringing call when the user presses the volume button during ringing.

If this method is called prior to when the ringtone begins playing, the ringtone will not be silenced. As such it is not intended as a means to avoid playing of a ringtone.

A dialer app which wants to have more control over ringtone playing should declare `TelecomManager#METADATA_IN_CALL_SERVICE_RINGING` in the manifest entry for their `InCallService` implementation to indicate that the app wants to be responsible for playing the ringtone for all incoming calls.

Requires permission: `Manifest.permission.MODIFY_PHONE_STATE` or that the app fills the dialer role (see `getDefaultDialerPackage()`).
Requires `Manifest.permission.MODIFY_PHONE_STATE`

### startConference

    public void startConference (List<Uri> participants,
                    Bundle extras)

Place a new adhoc conference call with the provided participants using the system telecom service. This method doesn't support placing of emergency calls. An adhoc conference call is established by providing a list of addresses to `TelecomManager#startConference(List<Uri>, int videoState)` where the `ConnectionService` is responsible for connecting all indicated participants to a conference simultaneously. This is in contrast to conferences formed by merging calls together (e.g. using `Call.mergeConference()`). The following keys are supported in the supplied extras.

- `EXTRA_PHONE_ACCOUNT_HANDLE`
- `EXTRA_START_CALL_WITH_SPEAKERPHONE`
- `EXTRA_START_CALL_WITH_VIDEO_STATE`

Requires `Manifest.permission.CALL_PHONE`
