Is there any way to handle OutOfMemoryException in Android while using Bitmap of large number of pictures. I tried all the solutions given in this site ie(GC, Bitmap.reset()). I just want to know whether any alert can be generated before the heap memory is going to full? so that i can handle it in a different way.

    Just a note: never ever catch OutOfMemoryException. That can lead to totally unexpected behaviour and is considered a bad practice. Commented Mar 14, 2011 at 9:24

In your Activity there is a callback function you can implement to be notified of low memory issues:

http://developer.android.com/reference/android/content/ComponentCallbacks.html#onLowMemory() 

@Override
public void onLowMemory() {
 super.onLowMemory();
 // Your memory releasing code
}

Note this applies to the overall system. It has almost no relation to a single app running out of managed heap space (which is what what cause an OOM).
-1. As fadden pointed out, this method won't get called even if your app is OOM.
