How to trace and debug external memory allocations in Android?

I am trying to fix a memory issue in an Android application.

I am convinced that the memory leak is not happening on the internal heap, as I have thoroughly investigated this possibility using the Memory Analyzer Tool, and the Heap/Allocation Tracker in DDMS.

I believe to find the source of the problem, I have to look at the allocations on the external heap, rather than the internal heap.

10-05 18:17:06.22开发者_开发百科1: DEBUG/dalvikvm(2559): GC_CONCURRENT freed 1137K, 47% free 4556K/8455K, external 1625K/2137K, paused 6ms+4ms

The external figure is the one that is ballooning out of control before a crash.

Is there a way to do this?

Cheers.

Have you used the MAT tool? It's very useful.

If you're having problems with memory due to Bitmaps, look into WeakReference or make sure to call recycle() on your bitmaps when you're done.
