How do I discover memory usage of my application in Android?

Question

How can I find the memory used on my Android application, programmatically?

I hope there is a way to do it. Plus, how do I get the free memory of the phone too?

Answer 1

1) I guess not, at least not from Java.
2)

ActivityManager activityManager = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
MemoryInfo mi = new MemoryInfo();
activityManager.getMemoryInfo(mi);
Log.i("memory free", "" + mi.availMem);
