I was developing a Livewallpaper which uses a open-source game engine called Andengine(andengine.org), it works fine now except sometimes when user set my Livewallpaper as wall paper, an Exception will be thrown saying "Failed to register input channel. Check logs for details.", but the werid thing is the Livewallpaper still works and did not exit.

Any idea what maybe causing this problem , or how I can fix it?

  • (1) Did you check "the logs"? (2) Do you have a second round in the stack trace that starts with "caused by:"? – Aleadam Apr 24 '11 at 05:52
  • @Aleadam No there is only one round of stack trace. And the only logs I found related to this issue is " call to OpenGL ES API with no current context (logged once per thread)" as I list above – CarlLee Apr 24 '11 at 06:01
  • @Aleadam also " Input channel is not initialized" – CarlLee Apr 24 '11 at 06:02
  • @Aleadam I found out it was because I was using launcher pro for test, it doesn't release the hardware OpenGL ES was currently using when the user clicks "Set wallpaper" button – CarlLee Apr 24 '11 at 06:22

Sorry, I could only find that the InputQueue "provides a mechanism for an application to receive incoming input events. Currently only usable from native code".

Check the GLSurfaceView class in andengine. That may give you a clue of what is wrong with your wallpaper

You may also want to check why this is happening:

    Thank you very much, I figured out it has something to do with Launcher Pro, which didn't release the hardware after user set me as wallpaper fast enough. If I change to android original Home Screen the Exception is gone. – CarlLee Apr 24 '11 at 06:25
  • Launcher Pro has its issues. I've seen some weird bugs with it (although IMHO is still the best launcher out there). I would consider sending them a bug report so they might try to to fix it and release the hw sooner. – Aleadam Apr 24 '11 at 06:32
  • Yes, but I am not sure what the cause is, but it's definitely their issue, so I'll send them a bug report. – CarlLee Apr 24 '11 at 07:25
