Kotlin |Java

open class TelecomManager

kotlin.Any
↳	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 android.content.Context#getSystemService.

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).

static val METADATA_INCLUDE_EXTERNAL_CALLS: String

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.

Value: "android.telecom.INCLUDE_EXTERNAL_CALLS"

METADATA_INCLUDE_SELF_MANAGED_CALLS

Added in API level 26

static val METADATA_INCLUDE_SELF_MANAGED_CALLS: String

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.

acceptHandover

Added in API level 28

open fun acceptHandover(
    srcAddr: Uri!, 
    videoState: Int, 
    destAcct: PhoneAccountHandle!
): Unit

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 android.telecom.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 android.telecom.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 and the user must have enabled the corresponding PhoneAccount. This can be checked using getPhoneAccount. Self-managed ConnectionServices must have android.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 android.Manifest.permission#MANAGE_OWN_CALLS.

Parameters
srcAddr	Uri!: The android.net.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 android.telecom.VideoProfile#STATE_AUDIO_ONLY, android.telecom.VideoProfile#STATE_TX_ENABLED, android.telecom.VideoProfile#STATE_RX_ENABLED, android.telecom.VideoProfile#STATE_BIDIRECTIONAL, and android.telecom.VideoProfile#STATE_PAUSED
destAcct	PhoneAccountHandle!: The PhoneAccountHandle registered to the calling package.

acceptRingingCall

Added in API level 26
Deprecated in API level 29

open fun acceptRingingCall(): Unit

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 android.Manifest.permission#ANSWER_PHONE_CALLS or android.Manifest.permission#MODIFY_PHONE_STATE

acceptRingingCall

Added in API level 26
Deprecated in API level 29

open fun acceptRingingCall(videoState: Int): Unit

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 android.Manifest.permission#ANSWER_PHONE_CALLS or android.Manifest.permission#MODIFY_PHONE_STATE

Parameters
videoState	Int: The desired video state to answer the call with.

addCall

Added in API level 34

open fun addCall(
    callAttributes: CallAttributes, 
    executor: Executor, 
    pendingControl: OutcomeReceiver<CallControl!, CallException!>, 
    handshakes: CallControlCallback, 
    events: CallEventCallback
): Unit

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 android.app.Notification.CallStyle notification should be posted and when the call is ready to be disconnected, use CallControl.disconnect(DisconnectCause, 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 android.app.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 android.app.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) )
                               }

• PhoneAccount does not have property PhoneAccount.CAPABILITY_SELF_MANAGED set (i.e. it is a managed ConnectionService), and the active, held or ringing call limit has been reached.
• PhoneAccount has property PhoneAccount.CAPABILITY_SELF_MANAGED set (i.e. it is a self-managed ConnectionService and there is an ongoing call in another ConnectionService.
• There is an ongoing emergency call.

Parameters
phoneAccountHandle	PhoneAccountHandle!: The PhoneAccountHandle the call will be added for.

Return
Boolean	true if telecom will permit an outgoing call to be placed, false otherwise.

isTtySupported

Added in API level 28

open fun isTtySupported(): Boolean

Returns whether TTY is supported on this device.
Requires android.Manifest.permission.READ_PRIVILEGED_PHONE_STATE or android.Manifest.permission#READ_PHONE_STATE

isVoiceMailNumber

Added in API level 23

open fun isVoiceMailNumber(
    accountHandle: PhoneAccountHandle!, 
    number: String!
): Boolean

Return whether a given phone number is the configured voicemail number for a particular phone account.
Requires android.Manifest.permission#READ_PHONE_STATE

Parameters
accountHandle	PhoneAccountHandle!: The handle for the account to check the voicemail number against
number	String!: The number to look up.

placeCall

Added in API level 23

open fun placeCall(
    address: Uri!, 
    extras: Bundle!
): Unit

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: android.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 android.telecom.PhoneAccountHandle. Self-managed ConnectionServices require permission android.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: android.app.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.
Requires android.Manifest.permission#CALL_PHONE or android.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

open fun registerPhoneAccount(account: PhoneAccount!): Unit

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.

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

open fun showInCallScreen(showDialpad: Boolean): Unit

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 android.Manifest.permission#READ_PHONE_STATE permission.

Requires android.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

open fun silenceRinger(): Unit

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

startConference

Added in API level 31

open fun startConference(
    participants: MutableList<Uri!>, 
    extras: Bundle
): Unit

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 android.telecom.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 android.Manifest.permission#CALL_PHONE

Parameters
participants	MutableList<Uri!>: 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.

unregisterPhoneAccount

Added in API level 23

open fun unregisterPhoneAccount(accountHandle: PhoneAccountHandle!): Unit

Remove a PhoneAccount registration from the system.

Parameters
accountHandle	PhoneAccountHandle!: A PhoneAccountHandle for the PhoneAccount to unregister.
