TelecomManager

Kotlin |Java

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.
Requires the PackageManager#FEATURE_TELECOM feature which can be detected using PackageManager.hasSystemFeature(String).

Public methods

acceptHandover

Added in API level 28

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 ConnectionServices, 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 ConnectionServices 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\u2019s `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

Added in API level 26
Deprecated in API level 29

public void acceptRingingCall (int videoState)

This method was deprecated in API level 29.
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

Added in API level 26
Deprecated in API level 29

public void acceptRingingCall ()

This method was deprecated in API level 29.
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. If the ringing incoming call is self-managed, this method will only accept the call if the caller of this method is privileged (i.e. system, shell, or root) or system UI.
Requires Manifest.permission.ANSWER_PHONE_CALLS or Manifest.permission.MODIFY_PHONE_STATE

addCall

Added in API level 34

public void addCall (CallAttributes callAttributes, 
                Executor executor, 
                OutcomeReceiver<CallControl, CallException> pendingControl, 
                CallControlCallback handshakes, 
                CallEventCallback events)

Add a call to the Android system service Telecom. This allows the system to start tracking an incoming or outgoing call with the specified CallAttributes. Once a call is added, a Notification.CallStyle notification should be posted and when the call is ready to be disconnected, use CallControl.disconnect(DisconnectCause, Executor, OutcomeReceiver) which is provided by the pendingControl#onResult(CallControl).

Call Lifecycle: Your app is given foreground execution priority as long as you have a valid call and are posting a Notification.CallStyle notification. When your application is given foreground execution priority, your app is treated as a foreground service. Foreground execution priority will prevent the ActivityManager from killing your application when it is placed the background. Foreground execution priority is removed from your app when all of your app's calls terminate or your app no longer posts a valid notification.

Note: Only packages that register with PhoneAccount.CAPABILITY_SUPPORTS_TRANSACTIONAL_OPERATIONS can utilize this API. PhoneAccounts that set the capabilities PhoneAccount.CAPABILITY_SIM_SUBSCRIPTION, PhoneAccount.CAPABILITY_CALL_PROVIDER, PhoneAccount.CAPABILITY_CONNECTION_MANAGER are not supported and will cause an exception to be thrown.

Usage example:

  // Its up to your app on how you want to wrap the objects. One such implementation can be:
  class MyVoipCall {
    ...
      public CallControlCallEventCallback handshakes = new  CallControlCallback() {
                         ...
                        }

      public CallEventCallback events = new CallEventCallback() {
                         ...
                        }

      public MyVoipCall(String id){
          ...
      }
  }

 MyVoipCall myFirstOutgoingCall = new MyVoipCall("1");

 telecomManager.addCall(callAttributes,
                        Runnable::run,
                        new OutcomeReceiver() {
                              public void onResult(CallControl callControl) {
                                 // The call has been added successfully. For demonstration
                                 // purposes, the call is disconnected immediately ...
                                 callControl.disconnect(
                                                 new DisconnectCause(DisconnectCause.LOCAL) )
                              }
                           },
                           myFirstOutgoingCall.handshakes,
                           myFirstOutgoingCall.events);

Requires Manifest.permission.MANAGE_OWN_CALLS

Parameters
`callAttributes`	`CallAttributes`: attributes of the new call (incoming or outgoing, address, etc.) This value cannot be `null`.
`executor`	`Executor`: execution context to run `CallControlCallback` updates on This value cannot be `null`. Callback and listener events are dispatched through this `Executor`, providing an easy way to control which thread is used. To dispatch events through the main thread of your application, you can use `Context.getMainExecutor()`. Otherwise, provide an `Executor` that dispatches to an appropriate thread.
`pendingControl`	`OutcomeReceiver`: Receives the result of addCall transaction. Upon success, a CallControl object is provided which can be used to do things like disconnect the call that was added. This value cannot be `null`.
`handshakes`	`CallControlCallback`: callback that receives actionable updates that originate from Telecom. This value cannot be `null`.
`events`	`CallEventCallback`: callback that receives non-actionable updates that originate from Telecom. This value cannot be `null`.

addNewIncomingCall

Added in API level 23

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 ConnectionServices, 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 ConnectionServices must have Manifest.permission.MANAGE_OWN_CALLS to add a new incoming call.

Specify the address associated with the incoming call using EXTRA_INCOMING_CALL_ADDRESS. If an incoming call is from an anonymous source, omit this extra and ensure you specify a valid number presentation via Connection.setAddress(Uri, int) on the Connection instance you return in your ConnectionService.onCreateIncomingConnection(PhoneAccountHandle, ConnectionRequest) implementation.

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.

Note: Notification.CallStyle notifications should be posted after the call is added to Telecom in order for the notification to be non-dismissible.

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

placeCall

Added in API level 23

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.

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 ConnectionServices 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.

Note: Notification.CallStyle notifications should be posted after the call is placed in order for the notification to be non-dismissible.

Note: Call Forwarding MMI codes can only be dialed by applications that are configured as the user defined default dialer or system dialer role. If a call containing a call forwarding MMI code is placed by an application that is not in one of these roles, the dialer will be launched with a UI showing the MMI code already populated so that the user can confirm the action before the call is placed.

Note: The dialer application may set the URI parameter of address to specify a call log record. This allows the dialer to launch a related application to initiate a callback for a specific call log entry. The dialer must have the READ_CALL_LOGS permission to access call log records. The ContentUri for a specific call log record can be obtained by ERROR(/android.content.ContentUri#withAppendedId(CallLog.Calls.CONTENT_URI, callLogId)), where callLogId is the BaseColumns._ID of the call log record.
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

Added in API level 23

public void registerPhoneAccount (PhoneAccount account)

Register a PhoneAccount for use by the system that will be stored in Device Encrypted storage. When registering PhoneAccounts, 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.

Note: Each package is limited to 10 PhoneAccount registrations.

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.

A IllegalArgumentException will be thrown if an app tries to register a PhoneAccount when the upper bound limit, 10, has already been reached.

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

Throws

UnsupportedOperationException if the caller cannot modify phone state and the device does not have the Telecom feature.

Throws
`UnsupportedOperationException`	if the caller cannot modify phone state and the device does not have the Telecom feature.
`SecurityException`	if: the caller cannot modify phone state and the phone account doesn't belong to the calling user. the caller is registering a self-managed phone and either they are not allowed to manage their own calls or if the account is call capable, a connection manager, or a sim account. the caller is registering a sim account without the ability to do so. the caller is registering a multi-user phone account but isn't a system app. the account can make SIM-based voice calls but the caller cannot register sim accounts or isn't a sim call manager. the account defines the EXTRA_SKIP_CALL_FILTERING extra but the caller isn't able to modify the phone state. the caller is registering an account for a different user but isn't able to interact across users. if simultaneous calling is available and the phone account package name doesn't correspond to the simultaneous calling accounts associated with this phone account.

SecurityException

if:

the caller cannot modify phone state and the phone account doesn't belong to the calling user.
the caller is registering a self-managed phone and either they are not allowed to manage their own calls or if the account is call capable, a connection manager, or a sim account.
the caller is registering a sim account without the ability to do so.
the caller is registering a multi-user phone account but isn't a system app.
the account can make SIM-based voice calls but the caller cannot register sim accounts or isn't a sim call manager.
the account defines the EXTRA_SKIP_CALL_FILTERING extra but the caller isn't able to modify the phone state.
the caller is registering an account for a different user but isn't able to interact across users.
if simultaneous calling is available and the phone account package name doesn't correspond to the simultaneous calling accounts associated with this phone account.

showInCallScreen

Added in API level 21

public void showInCallScreen (boolean showDialpad)

Brings the in-call screen to the foreground if there is an ongoing call. If there is currently no ongoing call, then this method does nothing.

Requires that the method-caller be set as the system dialer app or have the Manifest.permission.READ_PHONE_STATE permission.

Requires Manifest.permission.READ_PHONE_STATE

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

silenceRinger

Added in API level 23

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

Added in API level 31

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.

Requires Manifest.permission.CALL_PHONE

Parameters
`participants`	`List`: List of participants to start conference with This value cannot be `null`.
`extras`	`Bundle`: Bundle of extras to use with the call This value cannot be `null`.
