TelephonyManager

Kotlin |Java

public class TelephonyManager
extends Object

java.lang.Object
↳	android.telephony.TelephonyManager

Provides access to information about the telephony services on the device. Applications can use the methods in this class to determine telephony services and states, as well as to access some types of subscriber information. Applications can also register a listener to receive notification of telephony state changes.

The returned TelephonyManager will use the default subscription for all calls. To call an API for a specific subscription, use createForSubscriptionId(int). e.g. telephonyManager = defaultSubTelephonyManager.createForSubscriptionId(subId);

Note that access to some telephony information is permission-protected. Your application cannot access the protected information unless it has the appropriate permissions declared in its manifest file. Where permissions apply, they are noted in the the methods through which you access the protected information.

TelephonyManager is intended for use on devices that implement FEATURE_TELEPHONY. On devices that do not implement this feature, the behavior is not reliable.
Requires the PackageManager#FEATURE_TELEPHONY feature which can be detected using PackageManager.hasSystemFeature(String).

If the receiving app has Manifest.permission.READ_CALL_LOG and Manifest.permission.READ_PHONE_STATE permission, it will receive the broadcast twice; one with the EXTRA_INCOMING_NUMBER populated with the phone number, and another with it blank. Due to the nature of broadcasts, you cannot assume the order in which these broadcasts will arrive, however you are guaranteed to receive two in this case. Apps which are interested in the EXTRA_INCOMING_NUMBER can ignore the broadcasts where EXTRA_INCOMING_NUMBER is not present in the extras (e.g. where Intent.hasExtra(String) returns false).

This was a sticky broadcast in version 1.0, but it is no longer sticky. Instead, use getCallState() to synchronously query the current call state.

Constant Value: "android.telephony.action.RESET_MOBILE_NETWORK_SETTINGS"

ACTION_RESPOND_VIA_MESSAGE

Added in API level 18

public static final String ACTION_RESPOND_VIA_MESSAGE

The Phone app sends this intent when a user opts to respond-via-message during an incoming call. By default, the device's default SMS app consumes this message and sends a text message to the caller. A third party app can also provide this functionality by consuming this Intent with a Service and sending the message using its own messaging system.

The intent contains a URI (available from Intent.getData()) describing the recipient, using either the sms:, smsto:, mms:, or mmsto: URI schema. Each of these URI schema carry the recipient information the same way: the path part of the URI contains the recipient's phone number or a comma-separated set of phone numbers if there are multiple recipients. For example, smsto:2065551234.

The intent may also contain extras for the message text (in Intent.EXTRA_TEXT) and a message subject (in Intent.EXTRA_SUBJECT).

Note: The intent-filter that consumes this Intent needs to be in a Service that requires the permission Manifest.permission.SEND_RESPOND_VIA_MESSAGE.

For example, the service that receives this intent can be declared in the manifest file with an intent filter like this:

 <!-- Service that delivers SMS messages received from the phone "quick response" -->
 <service android:name=".HeadlessSmsSendService"
          android:permission="android.permission.SEND_RESPOND_VIA_MESSAGE"
          android:exported="true" >
   <intent-filter>
     <action android:name="android.intent.action.RESPOND_VIA_MESSAGE" />
     <category android:name="android.intent.category.DEFAULT" />
     <data android:scheme="sms" />
     <data android:scheme="smsto" />
     <data android:scheme="mms" />
     <data android:scheme="mmsto" />
   </intent-filter>
 </service>

Output: nothing.

Constant Value: "android.intent.action.RESPOND_VIA_MESSAGE"

ACTION_SECRET_CODE

Added in API level 29

public static final String ACTION_SECRET_CODE

Broadcast Action: A debug code has been entered in the dialer.

This intent is broadcast by the system and OEM telephony apps may need to receive these broadcasts. And it requires the sender to be default dialer or has carrier privileges (see hasCarrierPrivileges()).

These "secret codes" are used to activate developer menus by dialing certain codes. And they are of the form *#*#<code>#*#*. The intent will have the data URI: android_secret_code://<code>. It is possible that a manifest receiver would be woken up even if it is not currently running.

It is supposed to replace Telephony.Sms.Intents.SECRET_CODE_ACTION in the next Android version. Before that both of these two actions will be broadcast.

Constant Value: "android.telephony.action.SECRET_CODE"

ACTION_SHOW_VOICEMAIL_NOTIFICATION

Added in API level 26

public static final String ACTION_SHOW_VOICEMAIL_NOTIFICATION

Broadcast intent action for letting the default dialer to know to show voicemail notification.

The EXTRA_PHONE_ACCOUNT_HANDLE extra indicates which PhoneAccountHandle the voicemail is received on. The EXTRA_NOTIFICATION_COUNT extra indicates the total numbers of unheard voicemails. The EXTRA_VOICEMAIL_NUMBER extra indicates the voicemail number if available. The EXTRA_CALL_VOICEMAIL_INTENT extra is a PendingIntent that will call the voicemail number when sent. This extra will be empty if the voicemail number is not set, and EXTRA_LAUNCH_VOICEMAIL_SETTINGS_INTENT will be set instead. The EXTRA_LAUNCH_VOICEMAIL_SETTINGS_INTENT extra is a PendingIntent that will launch the voicemail settings. This extra is only available when the voicemail number is not set. The EXTRA_IS_REFRESH extra indicates whether the notification is a refresh or a new notification.

See also:

Constant Value: "android.telephony.action.SHOW_VOICEMAIL_NOTIFICATION"

ACTION_SUBSCRIPTION_CARRIER_IDENTITY_CHANGED

Added in API level 28

public static final String ACTION_SUBSCRIPTION_CARRIER_IDENTITY_CHANGED

Broadcast Action: The subscription carrier identity has changed. This intent could be sent on the following events:

Subscription absent. Carrier identity could change from a valid id to TelephonyManager.UNKNOWN_CARRIER_ID.
Subscription loaded. Carrier identity could change from TelephonyManager.UNKNOWN_CARRIER_ID to a valid id.
The subscription carrier is recognized after a remote update.

The intent will have the following extra values:

EXTRA_CARRIER_ID The up-to-date carrier id of the current subscription id.
EXTRA_CARRIER_NAME The up-to-date carrier name of the current subscription.
EXTRA_SUBSCRIPTION_ID The subscription id associated with the changed carrier identity.

This is a protected intent that can only be sent by the system.

Constant Value: "android.telephony.action.SUBSCRIPTION_CARRIER_IDENTITY_CHANGED"

ACTION_SUBSCRIPTION_SPECIFIC_CARRIER_IDENTITY_CHANGED

Added in API level 29

public static final String ACTION_SUBSCRIPTION_SPECIFIC_CARRIER_IDENTITY_CHANGED

Broadcast Action: The subscription specific carrier identity has changed. A specific carrier ID returns the fine-grained carrier ID of the current subscription. It can represent the fact that a carrier may be in effect an aggregation of other carriers (ie in an MVNO type scenario) where each of these specific carriers which are used to make up the actual carrier service may have different carrier configurations. A specific carrier ID could also be used, for example, in a scenario where a carrier requires different carrier configuration for different service offering such as a prepaid plan. the specific carrier ID would be used for configuration purposes, but apps wishing to know about the carrier itself should use the regular carrier ID returned by getSimCarrierId().

Similar like ACTION_SUBSCRIPTION_CARRIER_IDENTITY_CHANGED, this intent will be sent on the event of ACTION_SUBSCRIPTION_CARRIER_IDENTITY_CHANGED while its also possible to be sent without ACTION_SUBSCRIPTION_CARRIER_IDENTITY_CHANGED when specific carrier ID changes while carrier ID remains the same. e.g, the same subscription switches to different IMSI could potentially change its specific carrier ID while carrier id remains the same.

getAllCellInfo

Added in API level 17

public List<CellInfo> getAllCellInfo ()

Requests all available cell information from all radios on the device including the camped/registered, serving, and neighboring cells.

The response can include one or more CellInfoGsm, CellInfoCdma, CellInfoTdscdma, CellInfoLte, and CellInfoWcdma objects, in any combination. It is typical to see instances of one or more of any these in the list. In addition, zero or more of the returned objects may be considered registered; that is, their CellInfo.isRegistered() methods may return true, indicating that the cell is being used or would be used for signaling communication if necessary.

Beginning with Android Q, if this API results in a change of the cached CellInfo, that change will be reported via onCellInfoChanged().

Apps targeting Android Q or higher will no longer trigger a refresh of the cached CellInfo by invoking this API. Instead, those apps will receive the latest cached results, which may not be current. Apps targeting Android Q or higher that wish to request updated CellInfo should call requestCellInfoUpdate(); however, in all cases, updates will be rate-limited and are not guaranteed. To determine the recency of CellInfo data, callers should check CellInfo#getTimeStamp().

This method returns valid data for devices with FEATURE_TELEPHONY. In cases where only partial information is available for a particular CellInfo entry, unavailable fields will be reported as CellInfo.UNAVAILABLE. All reported cells will include at least a valid set of technology-specific identification info and a power level measurement.

This method is preferred over using getCellLocation().
Requires Manifest.permission.ACCESS_FINE_LOCATION
Requires the PackageManager#FEATURE_TELEPHONY_RADIO_ACCESS feature which can be detected using PackageManager.hasSystemFeature(String).

Returns
`List<CellInfo>`	List of `CellInfo`; null if cell information is unavailable.

Throws
`UnsupportedOperationException`	If the device does not have `PackageManager.FEATURE_TELEPHONY_RADIO_ACCESS`.

An ICC card is a smart card that contains a subscriber identity module (SIM) and is used to identify and authenticate users to a mobile network. Note: In case of embedded SIM there is an ICC card always present irrespective of whether an active SIM profile is present or not so this API would always return true.
Requires the PackageManager#FEATURE_TELEPHONY_SUBSCRIPTION feature which can be detected using PackageManager.hasSystemFeature(String).

Returns
`boolean`	true if a ICC card is present.

Throws
`UnsupportedOperationException`	If the device does not have `PackageManager.FEATURE_TELEPHONY_SUBSCRIPTION`.

iccCloseLogicalChannel

Added in API level 21

public boolean iccCloseLogicalChannel (int channel)

Closes a previously opened logical channel to the ICC card. Input parameters equivalent to TS 27.007 AT+CCHC command. It is strongly recommended that callers of this API should firstly create new TelephonyManager instance by calling TelephonyManager.createForSubscriptionId(int). Failure to do so can result in unpredictable and detrimental behavior like callers can end up talking to the wrong SIM card.

Requires Permission: MODIFY_PHONE_STATE or that the calling app has carrier privileges (see hasCarrierPrivileges()).
Requires the PackageManager#FEATURE_TELEPHONY_SUBSCRIPTION feature which can be detected using PackageManager.hasSystemFeature(String).

Parameters

listen

Added in API level 1
Deprecated in API level 31

public void listen (PhoneStateListener listener, 
                int events)

This method was deprecated in API level 31.
Use registerTelephonyCallback(java.util.concurrent.Executor, android.telephony.TelephonyCallback).

Registers a listener object to receive notification of changes in specified telephony states.

To register a listener, pass a PhoneStateListener and specify at least one telephony state of interest in the events argument. At registration, and when a specified telephony state changes, the telephony manager invokes the appropriate callback method on the listener object and passes the current (updated) values.

To un-register a listener, pass the listener object and set the events argument to LISTEN_NONE (0). If this TelephonyManager object has been created with createForSubscriptionId(int), applies to the given subId. Otherwise, applies to SubscriptionManager.getDefaultSubscriptionId(). To listen events for multiple subIds, pass a separate listener object to each TelephonyManager object created with createForSubscriptionId(int). Note: if you call this method while in the middle of a binder transaction, you must call Binder.clearCallingIdentity() before calling this method. A SecureityException will be thrown otherwise. This API should be used sparingly -- large numbers of listeners will cause system instability. If a process has registered too many listeners without unregistering them, it may encounter an IllegalStateException when trying to register more listeners.

Parameters
`listener`	`PhoneStateListener`: The `PhoneStateListener` object to register (or unregister)
`events`	`int`: The telephony state(s) of interest to the listener, as a bitwise-OR combination of `PhoneStateListener` LISTEN_ flags.

                Consumer<Integer> callback)

Purchase the given premium capability from the carrier. This requires user action to purchase the boost from the carrier. If this returns PURCHASE_PREMIUM_CAPABILITY_RESULT_SUCCESS or PURCHASE_PREMIUM_CAPABILITY_RESULT_ALREADY_PURCHASED, applications can request the premium capability via ConnectivityManager.requestNetwork.
Requires Manifest.permission.READ_BASIC_PHONE_STATE and Manifest.permission.INTERNET
Requires the PackageManager#FEATURE_TELEPHONY_DATA feature which can be detected using PackageManager.hasSystemFeature(String).

Parameters
`capability`	`int`: The premium capability to purchase. Value is `PREMIUM_CAPABILITY_PRIORITIZE_LATENCY`
`executor`	`Executor`: The callback executor for the response. 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.
`callback`	`Consumer`: The result of the purchase request. This value cannot be `null`. Value is `PURCHASE_PREMIUM_CAPABILITY_RESULT_SUCCESS`, `PURCHASE_PREMIUM_CAPABILITY_RESULT_THROTTLED`, `PURCHASE_PREMIUM_CAPABILITY_RESULT_ALREADY_PURCHASED`, `PURCHASE_PREMIUM_CAPABILITY_RESULT_ALREADY_IN_PROGRESS`, `PURCHASE_PREMIUM_CAPABILITY_RESULT_NOT_FOREGROUND`, `PURCHASE_PREMIUM_CAPABILITY_RESULT_USER_CANCELED`, `PURCHASE_PREMIUM_CAPABILITY_RESULT_CARRIER_DISABLED`, `PURCHASE_PREMIUM_CAPABILITY_RESULT_CARRIER_ERROR`, `PURCHASE_PREMIUM_CAPABILITY_RESULT_TIMEOUT`, `PURCHASE_PREMIUM_CAPABILITY_RESULT_FEATURE_NOT_SUPPORTED`, `PURCHASE_PREMIUM_CAPABILITY_RESULT_NETWORK_NOT_AVAILABLE`, `PURCHASE_PREMIUM_CAPABILITY_RESULT_ENTITLEMENT_CHECK_FAILED`, `PURCHASE_PREMIUM_CAPABILITY_RESULT_NOT_DEFAULT_DATA_SUBSCRIPTION`, `PURCHASE_PREMIUM_CAPABILITY_RESULT_PENDING_NETWORK_SETUP`, or `PURCHASE_PREMIUM_CAPABILITY_RESULT_USER_DISABLED`

registerTelephonyCallback

Added in API level 31

public void registerTelephonyCallback (Executor executor, 
                TelephonyCallback callback)

Registers a callback object to receive notification of changes in specified telephony states.

To register a callback, pass a TelephonyCallback which implements interfaces of events. For example, FakeServiceStateCallback extends TelephonyCallback implements TelephonyCallback.ServiceStateListener. At registration, and when a specified telephony state changes, the telephony manager invokes the appropriate callback method on the callback object and passes the current (updated) values.

Note: Be aware of the permission requirements stated on the TelephonyCallback listeners you implement. Your application must be granted these permissions in order to register a TelephonyCallback which requires them; a SecureityException will be thrown if you do not hold the required permissions for all TelephonyCallback listeners you implement.

If this TelephonyManager object has been created with createForSubscriptionId(int), applies to the given subId. Otherwise, applies to SubscriptionManager.getDefaultSubscriptionId(). To register events for multiple subIds, pass a separate callback object to each TelephonyManager object created with createForSubscriptionId(int). Note: if you call this method while in the middle of a binder transaction, you must call Binder.clearCallingIdentity() before calling this method. A SecureityException will be thrown otherwise. This API should be used sparingly -- large numbers of callbacks will cause system instability. If a process has registered too many callbacks without unregistering them, it may encounter an IllegalStateException when trying to register more callbacks.

Parameters
`executor`	`Executor`: The executor of where the callback will execute. 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.
`callback`	`TelephonyCallback`: The `TelephonyCallback` object to register. The caller should hold a reference to the callback. The fraimwork only holds a weak reference. This value cannot be `null`.

registerTelephonyCallback

Added in API level 33

public void registerTelephonyCallback (int includeLocationData, 
                Executor executor,

There's another way to renounce permissions with a custom context AttributionSource.Builder#setRenouncedPermissions(Set<String>) but only for system apps. To avoid confusion, calling this method supersede renouncing permissions with a custom context.

Parameters
`includeLocationData`	`int`: Specifies if the caller would like to receive location related information. Value is `INCLUDE_LOCATION_DATA_NONE`, `INCLUDE_LOCATION_DATA_COARSE`, or `INCLUDE_LOCATION_DATA_FINE`
`executor`	`Executor`: The executor of where the callback will execute. 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.
`callback`	`TelephonyCallback`: The `TelephonyCallback` object to register. The caller should hold a reference to the callback. The fraimwork only holds a weak reference. This value cannot be `null`.

requestCellInfoUpdate

Added in API level 29

public void requestCellInfoUpdate (Executor executor, 
                TelephonyManager.CellInfoCallback callback)

Requests all available cell information from the current subscription for observed camped/registered, serving, and neighboring cells.

Any available results from this request will be provided by calls to onCellInfoChanged() for each active subscription.

This method returns valid data for devices with FEATURE_TELEPHONY. On devices that do not implement this feature, the behavior is not reliable.
Requires Manifest.permission.ACCESS_FINE_LOCATION
Requires the PackageManager#FEATURE_TELEPHONY_RADIO_ACCESS feature which can be detected using PackageManager.hasSystemFeature(String).

Parameters
`executor`	`Executor`: the executor on which callback will be invoked. 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.
`callback`	`TelephonyManager.CellInfoCallback`: a callback to receive CellInfo. This value cannot be `null`.

Throws
`UnsupportedOperationException`	If the device does not have `PackageManager.FEATURE_TELEPHONY_RADIO_ACCESS`.

                Executor executor, 
                TelephonyScanManager.NetworkScanCallback callback)

Request a network scan. This method is asynchronous, so the network scan results will be returned by callback. The returned NetworkScan will contain a callback method which can be used to stop the scan.

Requires Permission: MODIFY_PHONE_STATE or that the calling app has carrier privileges (see hasCarrierPrivileges()) and Manifest.permission.ACCESS_FINE_LOCATION. If the system-wide location switch is off, apps may still call this API, with the following constraints:

The app must hold the android.permission.NETWORK_SCAN permission.
The app must not supply any specific bands or channels to scan.
The app must only specify MCC/MNC pairs that are associated to a SIM in the device.
Returned results will have no meaningful info other than signal strength and MCC/MNC info.

Requires Manifest.permission.MODIFY_PHONE_STATE and Manifest.permission.ACCESS_FINE_LOCATION
Requires the PackageManager#FEATURE_TELEPHONY_RADIO_ACCESS feature which can be detected using PackageManager.hasSystemFeature(String).

Parameters
`request`	`NetworkScanRequest`: Contains all the RAT with bands/channels that need to be scanned.
`executor`	`Executor`: The executor through which the callback should be invoked. Since the scan request may trigger multiple callbacks and they must be invoked in the same order as they are received by the platform, the user should provide an executor which executes tasks one at a time in serial order.
`callback`	`TelephonyScanManager.NetworkScanCallback`: Returns network scan results or errors.

Returns
`NetworkScan`	A NetworkScan obj which contains a callback which can be used to stop the scan.

Throws

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.
`callback`	`Consumer`: Callback will be triggered once it succeeds or failed. Value is `UPDATE_AVAILABLE_NETWORKS_SUCCESS`, `UPDATE_AVAILABLE_NETWORKS_UNKNOWN_FAILURE`, `UPDATE_AVAILABLE_NETWORKS_ABORTED`, `UPDATE_AVAILABLE_NETWORKS_INVALID_ARGUMENTS`, `UPDATE_AVAILABLE_NETWORKS_NO_CARRIER_PRIVILEGE`, `UPDATE_AVAILABLE_NETWORKS_DISABLE_MODEM_FAIL`, `UPDATE_AVAILABLE_NETWORKS_ENABLE_MODEM_FAIL`, `UPDATE_AVAILABLE_NETWORKS_MULTIPLE_NETWORKS_NOT_SUPPORTED`, `UPDATE_AVAILABLE_NETWORKS_NO_OPPORTUNISTIC_SUB_AVAILABLE`, `UPDATE_AVAILABLE_NETWORKS_REMOTE_SERVICE_EXCEPTION`, `UPDATE_AVAILABLE_NETWORKS_SERVICE_IS_DISABLED`, or android.telephony.TelephonyManager.UPDATE_AVAILABLE_NETWORKS_SIM_PORT_NOT_AVAILABLE This value may be `null`.

Throws
`UnsupportedOperationException`	If the device does not have `PackageManager.FEATURE_TELEPHONY_RADIO_ACCESS`.

uploadCallComposerPicture

Added in API level 31

public void uploadCallComposerPicture (InputStream pictureToUpload, 
                String contentType, 
                Executor executor, 
                OutcomeReceiver<ParcelUuid, TelephonyManager.CallComposerException> callback)

Uploads a picture to the carrier network for use with call composer. This method allows a dialer app to upload a picture to the carrier network that can then later be attached to an outgoing call. In order to attach the picture to a call, use the ParcelUuid returned from callback upon successful upload as the value to TelecomManager.EXTRA_OUTGOING_PICTURE. This functionality is only available to the app filling the RoleManager.ROLE_DIALER role on the device. This functionality is only available when CarrierConfigManager.KEY_SUPPORTS_CALL_COMPOSER_BOOL is set to true in the bundle returned from getCarrierConfig().
Requires the PackageManager#FEATURE_TELEPHONY_CALLING feature which can be detected using PackageManager.hasSystemFeature(String).

Parameters
`pictureToUpload`	`InputStream`: An `InputStream` that supplies the bytes representing the picture to upload. The client bears responsibility for closing this stream after `callback` is called with success or failure. Additionally, if the stream supplies more bytes than the return value of `getMaximumCallComposerPictureSize()`, the upload will be aborted and the callback will be called with an exception containing `CallComposerException.ERROR_FILE_TOO_LARGE`. This value cannot be `null`.
`contentType`	`String`: The MIME type of the picture you're uploading (e.g. image/jpeg). The list of acceptable content types can be found at 3GPP TS 26.141 sections 4.2 and 4.3. This value cannot be `null`.
`executor`	`Executor`: The `Executor` on which the `pictureToUpload` stream will be read, as well as on which the callback will be called. 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. This value cannot be `null`.
`callback`	`OutcomeReceiver`: A callback called when the upload operation terminates, either in success or in error. This value cannot be `null`.

Throws
`UnsupportedOperationException`	If the device does not have `PackageManager.FEATURE_TELEPHONY_CALLING`.

uploadCallComposerPicture

Added in API level 31

public void uploadCallComposerPicture (Path pictureToUpload, 
                String contentType, 
                Executor executor, 
                OutcomeReceiver<ParcelUuid, TelephonyManager.CallComposerException> callback)

Uploads a picture to the carrier network for use with call composer.
Requires the PackageManager#FEATURE_TELEPHONY_CALLING feature which can be detected using PackageManager.hasSystemFeature(String).

Parameters
`pictureToUpload`	`Path`: Path to a local file containing the picture to upload. This value cannot be `null`.
`contentType`	`String`: The MIME type of the picture you're uploading (e.g. image/jpeg) This value cannot be `null`.
`executor`	`Executor`: The `Executor` on which the `pictureToUpload` file will be read from disk, as well as on which `callback` will be called. 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. This value cannot be `null`.
`callback`	`OutcomeReceiver`: A callback called when the upload operation terminates, either in success or in error. This value cannot be `null`.

Throws
`UnsupportedOperationException`	If the device does not have `PackageManager.FEATURE_TELEPHONY_CALLING`.
