问题 I'm writing a program that should run every 10 minutes in the background. The code I have seems to work fine as long as I'm actively using my phone, but after a long period of time, say overnight, the process seems to stop on it's own. When my program is running as it should I can view it under the "cached process" on my device, but then it will stop showing in the list after awhile. I was reading about WakefulIntentService and was wondering if I need to use that. As I understand it, it will

问题 I need help about displaying the Now Playing Card in the Recommendations row. I read the post about it in the Android developers site, but that did not help me much. I have a service that streams the MP3 data without problems. I added the following code, but there's no Now Playing Card... @Override public void onCreate() { Log.i(TAG, "onCreate called"); mSession = new MediaSession(this, "MusicService"); mSession.setCallback(new MediaSessionCallback()); mSession.setFlags(MediaSession.FLAG

I have a service as part of an application which is running reasonably well, although there is an unusual bit of behaviour which I am trying to understand. To do this, I have been putting Log.d statement in various methods in classes to report state information at various points. All of these seem to be working (ie reporting the

问题 I have a Sticky Service and i'm stress testing the app by filling the phone's RAM. Once the RAM is full, the service is destroyed. Since it's a sticky service, it gets restarted automatically when the system has enough resources. But this happens only on stock android devices like Moto/Nexus. Devices like Xiaomi or Lava do not restart the sticky service, even on 5.1 Is anyone aware of such problems with heavily customized ROMs? Any workarounds to schedule a restart of my service when the

问题 I am making an app that creates tiny sprite animations that walk around your screen. I have a main activity, with a button "start service". This starts a service, which (in onCreate() ) creates a full-screen view and attaches it to the root window manager. This part works perfectly. It fills the screen, and you can leave the app, and the animations will still be visible over everything. The problem emerges when you rotate the device. Sprites have moved to the middle of the screen, but this is
