Code for logging native heap usage on Android

nativeHeap.java

public static void logHeap(Class clazz) {
	    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);
	    String APP = "Bitmap";
	    
	    Log.d(APP, "debug. =================================");
	    Log.d(APP, "debug.heap native: allocated " + df.format(allocated) + "MB of " + df.format(available) + "MB (" + df.format(free) + "MB free) in [" + clazz.getName().replaceAll("com.myapp.android.","") + "]");
	    Log.d(APP, "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)");
