How do I detect the heap size usage of an android application

Question

I would like to know the amount of heap space used by my android application in two ways: - programmatically - through DDMS.

I have referred to this post, prior to posting here. In that post, it is mentioned that, Debug.getNativeHeapSize() returns the heapsize. Is this the exact method I should use, in order to programmatically detect the heap size? If so, where should I log it in order to get the correct heapsize usage of my application?

here's what I use:

public static void logHeap() {         Double allocated = new Double(Debug.getNativeHeapAllocatedSize())/new Double((1048576));         Double available = new Double(Debug.getNativeHeapSize())/1048576.0;         Double free = new Double(Debug.getNativeHeapFreeSize())/1048576.0;         DecimalFormat df = new DecimalFormat();         df.setMaximumFractionDigits(2);         df.setMinimumFractionDigits(2);          Log.d("tag", "debug. =================================");         Log.d("tag", "debug.heap native: allocated " + df.format(allocated) + "MB of " + df.format(available) + "MB (" + df.format(free) + "MB free)");         Log.d("tag", "debug.memory: allocated: " + df.format(new Double(Runtime.getRuntime().totalMemory()/1048576)) + "MB of " + df.format(new Double(Runtime.getRuntime().maxMemory()/1048576))+ "MB (" + df.format(new Double(Runtime.getRuntime().freeMemory()/1048576)) +"MB free)");     }
