/**
|
|
* This service is implemented by an app that wishes to provide functionality for managing
|
|
* phone calls.
|
|
* <h2>Becoming the Default Phone App</h2>
|
|
* The default dialer/phone app is one which provides the in-call user interface while the device is
|
|
* in a call. It also provides the user with a means to initiate calls and see a history of calls
|
|
* on their device. A device is bundled with a system provided default dialer/phone app. The user
|
|
* may choose a single app to take over this role from the system app. An app which wishes to
|
|
* fulfill this role uses the {@link android.app.role.RoleManager} to request that they fill the
|
|
* {@link android.app.role.RoleManager#ROLE_DIALER} role.
|
|
* <p>
|
|
* The default phone app provides a user interface while the device is in a call, and the device is
|
|
* not in car mode (i.e. {@link UiModeManager#getCurrentModeType()} is not
|
|
* {@link android.content.res.Configuration#UI_MODE_TYPE_CAR}).
|
|
* <p>
|
|
* In order to fill the {@link android.app.role.RoleManager#ROLE_DIALER} role, an app must meet a
|
|
* number of requirements:
|
|
* <ul>
|
|
* <li>It must handle the {@link Intent#ACTION_DIAL} intent. This means the app must provide
|
|
* a dial pad UI for the user to initiate outgoing calls.</li>
|
|
* <li>It must fully implement the {@link InCallService} API and provide both an incoming call
|
|
* UI, as well as an ongoing call UI.</li>
|
|
* </ul>
|
|
* <p>
|
|
* Note: If the app filling the {@link android.app.role.RoleManager#ROLE_DIALER} returns a
|
|
* {@code null} {@link InCallService} during binding, the Telecom framework will automatically fall
|
|
* back to using the dialer app preloaded on the device. The system will display a notification to
|
|
* the user to let them know that their call was continued using the preloaded dialer app. Your
|
|
* app should never return a {@code null} binding; doing so means it does not fulfil the
|
|
* requirements of {@link android.app.role.RoleManager#ROLE_DIALER}.
|
|
* <p>
|
|
* Note: If your app fills {@link android.app.role.RoleManager#ROLE_DIALER} and makes changes at
|
|
* runtime which cause it to no longer fulfil the requirements of this role,
|
|
* {@link android.app.role.RoleManager} will automatically remove your app from the role and close
|
|
* your app. For example, if you use
|
|
* {@link android.content.pm.PackageManager#setComponentEnabledSetting(ComponentName, int, int)} to
|
|
* programmatically disable the {@link InCallService} your app declares in its manifest, your app
|
|
* will no longer fulfil the requirements expected of
|
|
* {@link android.app.role.RoleManager#ROLE_DIALER}.
|
|
* <p>
|
|
* The preloaded dialer will ALWAYS be used when the user places an emergency call, even if your
|
|
* app fills the {@link android.app.role.RoleManager#ROLE_DIALER} role. To ensure an optimal
|
|
* experience when placing an emergency call, the default dialer should ALWAYS use
|
|
* {@link android.telecom.TelecomManager#placeCall(Uri, Bundle)} to place calls (including
|
|
* emergency calls). This ensures that the platform is able to verify that the request came from
|
|
* the default dialer. If a non-preloaded dialer app uses {@link Intent#ACTION_CALL} to place an
|
|
* emergency call, it will be raised to the preloaded dialer app using {@link Intent#ACTION_DIAL}
|
|
* for confirmation; this is a suboptimal user experience.
|
|
* <p>
|
|
* Below is an example manifest registration for an {@code InCallService}. The meta-data
|
|
* {@link TelecomManager#METADATA_IN_CALL_SERVICE_UI} indicates that this particular
|
|
* {@code InCallService} implementation intends to replace the built-in in-call UI.
|
|
* The meta-data {@link TelecomManager#METADATA_IN_CALL_SERVICE_RINGING} indicates that this
|
|
* {@link InCallService} will play the ringtone for incoming calls. See
|
|
* <a href="#incomingCallNotification">below</a> for more information on showing the incoming call
|
|
* UI and playing the ringtone in your app.
|
|
* <pre>
|
|
* {@code
|
|
* <service android:name="your.package.YourInCallServiceImplementation"
|
|
* android:permission="android.permission.BIND_INCALL_SERVICE"
|
|
* android:exported="true">
|
|
* <meta-data android:name="android.telecom.IN_CALL_SERVICE_UI" android:value="true" />
|
|
* <meta-data android:name="android.telecom.IN_CALL_SERVICE_RINGING"
|
|
* android:value="true" />
|
|
* <intent-filter>
|
|
* <action android:name="android.telecom.InCallService"/>
|
|
* </intent-filter>
|
|
* </service>
|
|
* }
|
|
* </pre>
|
|
*
|
|
* <em>Note: You should NOT mark your {@link InCallService} with the attribute
|
|
* {@code android:exported="false"}; doing so can result in a failure to bind to your implementation
|
|
* during calls.</em>
|
|
* <p>
|
|
* In addition to implementing the {@link InCallService} API, you must also declare an activity in
|
|
* your manifest which handles the {@link Intent#ACTION_DIAL} intent. The example below illustrates
|
|
* how this is done:
|
|
* <pre>
|
|
* {@code
|
|
* <activity android:name="your.package.YourDialerActivity"
|
|
* android:label="@string/yourDialerActivityLabel">
|
|
* <intent-filter>
|
|
* <action android:name="android.intent.action.DIAL" />
|
|
* <category android:name="android.intent.category.DEFAULT" />
|
|
* </intent-filter>
|
|
* <intent-filter>
|
|
* <action android:name="android.intent.action.DIAL" />
|
|
* <category android:name="android.intent.category.DEFAULT" />
|
|
* <data android:scheme="tel" />
|
|
* </intent-filter>
|
|
* </activity>
|
|
* }
|
|
* </pre>
|
|
* <p>
|
|
* When a user installs your application and runs it for the first time, you should use the
|
|
* {@link android.app.role.RoleManager} to prompt the user to see if they would like your app to
|
|
* be the new default phone app.
|
|
* <p id="requestRole">
|
|
* The code below shows how your app can request to become the default phone/dialer app:
|
|
* <pre>
|
|
* {@code
|
|
* private static final int REQUEST_ID = 1;
|
|
*
|
|
* public void requestRole() {
|
|
* RoleManager roleManager = (RoleManager) getSystemService(ROLE_SERVICE);
|
|
* Intent intent = roleManager.createRequestRoleIntent(RoleManager.ROLE_DIALER);
|
|
* startActivityForResult(intent, REQUEST_ID);
|
|
* }
|
|
*
|
|
* @Override
|
|
* public void onActivityResult(int requestCode, int resultCode, Intent data) {
|
|
* if (requestCode == REQUEST_ID) {
|
|
* if (resultCode == android.app.Activity.RESULT_OK) {
|
|
* // Your app is now the default dialer app
|
|
* } else {
|
|
* // Your app is not the default dialer app
|
|
* }
|
|
* }
|
|
* }
|
|
* }
|
|
*
|
|
* </pre>
|
|
* <p id="companionInCallService">
|
|
* <h3>Access to InCallService for Wearable Devices</h3>
|
|
* <ol>
|
|
* If your app is a third-party companion app and wants to access InCallService APIs, what your
|
|
* app could do are:
|
|
* <p>
|
|
* <ol>
|
|
* <li> Declare MANAGE_ONGOING_CALLS permission in your manifest
|
|
* <li> Associate with a physical wearable device via the
|
|
* {@link android.companion.CompanionDeviceManager} API as a companion app. See:
|
|
* https://developer.android.com/guide/topics/connectivity/companion-device-pairing
|
|
* <li> Implement this InCallService with BIND_INCALL_SERVICE permission
|
|
* </ol>
|
|
* </ol>
|
|
* <p>
|
|
*
|
|
* </pre>
|
|
* <p id="incomingCallNotification">
|
|
* <h3>Showing the Incoming Call Notification</h3>
|
|
* When your app receives a new incoming call via {@link InCallService#onCallAdded(Call)}, it is
|
|
* responsible for displaying an incoming call UI for the incoming call. It should do this using
|
|
* {@link android.app.NotificationManager} APIs to post a new incoming call notification.
|
|
* <p>
|
|
* Where your app declares the meta-data {@link TelecomManager#METADATA_IN_CALL_SERVICE_RINGING}, it
|
|
* is responsible for playing the ringtone for incoming calls. Your app should create a
|
|
* {@link android.app.NotificationChannel} which specifies the desired ringtone. For example:
|
|
* <pre><code>
|
|
* NotificationChannel channel = new NotificationChannel(YOUR_CHANNEL_ID, "Incoming Calls",
|
|
* NotificationManager.IMPORTANCE_MAX);
|
|
* // other channel setup stuff goes here.
|
|
*
|
|
* // We'll use the default system ringtone for our incoming call notification channel. You can
|
|
* // use your own audio resource here.
|
|
* Uri ringtoneUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_RINGTONE);
|
|
* channel.setSound(ringtoneUri, new AudioAttributes.Builder()
|
|
* // Setting the AudioAttributes is important as it identifies the purpose of your
|
|
* // notification sound.
|
|
* .setUsage(AudioAttributes.USAGE_NOTIFICATION_RINGTONE)
|
|
* .setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
|
|
* .build());
|
|
*
|
|
* NotificationManager mgr = getSystemService(NotificationManager.class);
|
|
* mgr.createNotificationChannel(channel);
|
|
* </code></pre>
|
|
* <p>
|
|
* When your app receives a new incoming call, it creates a {@link android.app.Notification} for the
|
|
* incoming call and associates it with your incoming call notification channel. You can specify a
|
|
* {@link android.app.PendingIntent} on the notification which will launch your full screen
|
|
* incoming call UI. The notification manager framework will display your notification as a
|
|
* heads-up notification if the user is actively using the phone. When the user is not using the
|
|
* phone, your full-screen incoming call UI is used instead.
|
|
* For example:
|
|
* <pre><code>{@code
|
|
* // Create an intent which triggers your fullscreen incoming call user interface.
|
|
* Intent intent = new Intent(Intent.ACTION_MAIN, null);
|
|
* intent.setFlags(Intent.FLAG_ACTIVITY_NO_USER_ACTION | Intent.FLAG_ACTIVITY_NEW_TASK);
|
|
* intent.setClass(context, YourIncomingCallActivity.class);
|
|
* PendingIntent pendingIntent = PendingIntent.getActivity(context, 1, intent, PendingIntent.FLAG_MUTABLE_UNAUDITED);
|
|
*
|
|
* // Build the notification as an ongoing high priority item; this ensures it will show as
|
|
* // a heads up notification which slides down over top of the current content.
|
|
* final Notification.Builder builder = new Notification.Builder(context);
|
|
* builder.setOngoing(true);
|
|
* builder.setPriority(Notification.PRIORITY_HIGH);
|
|
*
|
|
* // Set notification content intent to take user to the fullscreen UI if user taps on the
|
|
* // notification body.
|
|
* builder.setContentIntent(pendingIntent);
|
|
* // Set full screen intent to trigger display of the fullscreen UI when the notification
|
|
* // manager deems it appropriate.
|
|
* builder.setFullScreenIntent(pendingIntent, true);
|
|
*
|
|
* // Setup notification content.
|
|
* builder.setSmallIcon( yourIconResourceId );
|
|
* builder.setContentTitle("Your notification title");
|
|
* builder.setContentText("Your notification content.");
|
|
*
|
|
* // Use builder.addAction(..) to add buttons to answer or reject the call.
|
|
*
|
|
* NotificationManager notificationManager = mContext.getSystemService(
|
|
* NotificationManager.class);
|
|
* notificationManager.notify(YOUR_CHANNEL_ID, YOUR_TAG, YOUR_ID, builder.build());
|
|
* }</pre>
