I'm having this error where my Live Wallpaper freezes randomly. Sometimes it takes a few minutes, sometimes when the phone wakes or I do something fast. I've been looking for this and found others with similar problems like this one:

It pointed me to those 2 links:

https://github.com/markfguerra/GLWallpaperService/issues/7

https://github.com/markfguerra/GLWallpaperService/issues/11

Is it possible that we have the same issues as them?

Hi, We have this same problem a lot on an HTC Desire. I see a lot about this bug all around Internet. There seems to be no real solution, but a lot of tricks to reduce its chances of occuring. Here is the open bug in android: http://code.google.com/p/android/issues/detail?id=6478

Hi again, This issue is very problematic for us, we have it several time per days (like 5-10 times) on an HTC Desire and it forces the user to remove the battery of the phone to restart it and be able to unlock it ! This is a huge problem for any real application using AndEngine ! Here are a few links related to this issue, but I'm not good enough with the AndEngine OpenGL calls to be able to test the provided tricks... * https://groups.google.com/forum/?fromgroups=#!topic/android-developers/97axewT5PvM * http://www.mail-archive.com/[email protected]/msg110732.html * http://www.andengine.org/forums/post34505.html?hilit=rb_timestamp_wait_on_timestamp#p34505 * http://stackoverflow.com/questions/5018883/garbage-collector-hangs-opengl-on-htc-ev-es * http://stackoverflow.com/questions/8458404/android-cpu-may-be-pegged-bug * http://code.google.com/p/android/issues/detail?id=6478 * https://github.com/markfguerra/GLWallpaperService/issues/7 * https://developer.qualcomm.com/forum/qdevnet-forums/mobile-gaming-graphics-optimization-adreno/11525

Could someone help us on this one, please ? Regards
