It is one of the ironies of Java that though it is harder to write a memory leak than in C++, once you do manage it, it is harder to debug than in C++;)
IBM developerworks has some good articles on it. So, for example, though the article is old, and mentions rather dated GC technology, I do believe that the hints in http://www.ibm.com/developerworks/java/library/j-leaks/ are still pretty up to date for finding memory leaks. Unfortunately, he talks about using Jprobe, which I don't think you can run on an Android phone. But http://kohlerm.blogspot.com/2009/04/analyzing-memory-usage-off-your-android.html suggests using the hprof-conv tool and describes how to do that.
