[android-developers] Re: Out of memory exception on setting wallpaper
Hi , Thanks for the help . The problem is resolved . I had used a ContentResolver for listening to contacts updated and dint unregister them in the onDestroy() method . Now have included the code changes and it seems to work fine . Im still in a doubt if this was the real problem for the out of memory exception. Any comments are welcome .

It is *very* easy for an application to leak or simply to use too much memory.

Sounds like the Drawable remains attached to a View between rotations.

[android-developers] Re: Out of memory exception on setting wallpaper
getWallpaper() is not leaking. The default Home app is using it and does not experience out of memory errors because of that. I am more than willing to fix any existing memory leak in the framework (and I did several times) or in the default apps (and I did several times) but developers should really stop assuming that out of memory errors are always caused by the framework. It is *very* easy for an application to leak or simply to use too much memory.
