Android memory stat

I use the following code to get the memory usage. 

double allocated = Debug.getNativeHeapAllocatedSize() / (double) 1048576;
double available = Debug.getNativeHeapSize() / (double) 1048576.0;
double free = new Double(Debug.getNativeHeapFreeSize()) / (double) 1048576.0;

And I get the following log:

07-15 12:59:11.149: DEBUG/NKHeap(9363): debug.heap native: allocated 13,220MB of 16,059MB (0,108MB free)

My problem is that the free plus the allocated don't add up to the total. Am I missing something basic, or the is the precision I should expect?

To get the memory usage try something like:

Debug.MemoryInfo memoryInfo = new Debug.MemoryInfo();
Debug.getMemoryInfo(memoryInfo);

String memMessage = String.format("Memory: Pss=%.2f MB,
Private=%.2f MB, Shared=%.2f MB",
memoryInfo.getTotalPss() / 1024.0,
memoryInfo.getTotalPrivateDirty() / 1024.0,
memoryInfo.getTotalSharedDirty() / 1024.0);

You can read more about it in this blog here.
