I want to start a fullscreen activity automatically from a notification but I have trouble with the setFullScreenIntent. I followed this : https://developer.android.com/training/notify-user/time-sensitive and threads on internet but it's not workking for me. My notification appears but I have to press it to launch the activity.
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationManager notificationManager = this.getSystemService(NotificationManager.class);
if (notificationManager != null && notificationManager.getNotificationChannel(NOTIFICATION_CHANNEL_ID) == null) {
NotificationChannel channel = new NotificationChannel(NOTIFICATION_CHANNEL_ID, "channel_name", NotificationManager.IMPORTANCE_HIGH);
channel.setDescription("channel_description");
notificationManager.createNotificationChannel(channel);
}
}
Intent fullScreenIntent = new Intent(this, ResultActivity.class);
fullScreenIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
PendingIntent fullScreenPendingIntent = PendingIntent.getActivity(this, 0,
fullScreenIntent, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder notificationBuilder =
new NotificationCompat.Builder(this, NOTIFICATION_CHANNEL_ID)
.setSmallIcon(R.drawable.notification_icon)
.setContentTitle("Full Screen Notification")
.setContentText("Notification test text")
.setPriority(NotificationCompat.PRIORITY_HIGH)
.setCategory(NotificationCompat.CATEGORY_CALL)
.setDefaults(NotificationCompat.DEFAULT_ALL)
.setFullScreenIntent(fullScreenPendingIntent, true);
NotificationManagerCompat notificationManager = NotificationManagerCompat.from(this);
notificationManager.notify(12345, notificationBuilder.build());
Here my manifest :
<uses-permission android:name="android.permission.USE_FULL_SCREEN_INTENT" />
<activity
android:name=".ResultActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" /> -->
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
Thank you !
I am guessing that when you lock the phone, the Full-Screen Intent is shown properly, right?
What you are seeing is called heads-up notifications. As stated at the documentation, it's the normal behavior for high importance notifications and they appear when the device is unlocked.
What should you do?
Keep the full-screen intent for locked screens but also provide a custom layout to your notification which will present your feature in a better, contextual UI rather than the default notification.
Example:
The alarm application (on Pixel phones) has the following cases for triggered alarms:
