Monitoring heap in java android app

Question

The screen shot below shows DDMS in Eclipse monitoring the heap in an Android app (top, in red rectangle). In the LogCat window at the bottom, I have output of this statement:
Log.e("HEAP", "native, " + android.os.Debug.getNativeHeapSize() + " allocated, " + android.os.Debug.getNativeHeapAllocatedSize());
I would have expected these numbers to be the same, but they are not, so clearly my expectations are incorrect. Can you tell me what these numbers really are?
