| /** |
| * 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> |
