I am trying to make my Service running in foreground. I tried to use this example (please look for the section "Running a Service in the Foreground"), but startForeground() does not actually show my notification. And no exceptions is thrown. To make it shown, I need to use NotificationManager like here explained. With NotificationManager my notification works, but i'm not sure that my Service is foreground after this "silent" call to startForeground().

What can be wrong?

EDIT: I just tested this sample project that should demonstrate startForeground(), but it does not work! I use API v7.0, I tested it both on emulator and real device (SE Xperia Neo). Notification does not appear.

EDIT2: if i try to call setForeground() then i got a warning setForeground: ignoring old API call.

I also tried to use startForegroundCompat() as described here, but effect is absolutelly the same. I check if my service is foreground using ActivityManager.RunningServiceInfo as described here, and I see that my service is not foreground.

I just noticed that startForeground() doesn't show the notification icon if the id parameter is set to 0...

startForeground(0, notification); // Doesn't work...

startForeground(1, notification); // Works!!!

I hope that it could help someone stuck on this.

DMitry. I have just suffered your problem and found the cause.

If your app is changing state of a COMPONENT PackageManager.setComponentEnabledSetting()) Android removes the service from foregraound and its notification icon.

  • Since you elected to not provide source code, it will be difficult to help you directly. Here is a sample project that uses startForeground() successfully.
  • I did not provide source code because of my code is exactly the same as in example i provided: goo.gl/xXIvc . Thanks for the sample project.
  • I tested this sample project, it does not work! I use API v7.0, i tested it both on emulator and real device (SE Xperia Neo). Notification does not appear.
  • The sample project works perfectly fine -- I just re-tested it on a Nexus One, Galaxy Nexus, Nexus S, HTC Desire S, and the "API v7.0" emulator. To start the service and display the Notification, press the "Start the Player" button.
  • @CommonsWare, thanks for your time. And, of course, i pressed the "Start the Player" button =). Very strange, but it does not work for me on SE Xperia Neo and and API v7.0 emulator. Tomorrow i will test it on some kind of Acer, but i think the problem is in some different place, but i have absolutely no idea what could be wrong.
  • Wow that was a total surprise. Fixed it for me. Thanks!
  • and yet the documentation is woefully vague about what this id value even does... I am totally frustrated with the (IMO) poor documentation -_-
  • And I had 123 which didn't work, changed to 1 and it works!
  • @HerrGrumps The docs have been updated and now have a warning: "The integer ID you give to startForeground() must not be 0." (developer.android.com/guide/components/services.html). Better later than never =P
  • Do not use too big integers like 1337 , 13377331 , 137 . Just use 0x3, 0x1
  • Worked for me as well
  • Thanks for this. This isn't mentioned as required in the services documentation, but it certainly should be!
  • <Rant>Android's official documentation covers 10% of the subject.</Rant>
