Hackbod's is one of the best answers in SO. It throws light on a very obscure subject. It helped me a lot.

Another really helpful resource is this must-see video: [Google I/O 2011: Memory management for Android Apps][1]

**UPDATE:**

Process Stats, a service to discover how your app manages memory explained at this post by Dianne Hackborn: [http://android-developers.blogspot.com.es/2014/01/process-stats-understanding-how-your.html](http://android-developers.blogspot.com.es/2014/01/process-stats-understanding-how-your.html)

Well, you can check memory usage in Android with

getProcessMemoryInfo

function supported by Android.

ActivityManager activityManager = (ActivityManager)mContext.getSystemService(Context.ACTIVITY_SERVICE);
List<runningappprocessinfo> runningApps = activityManager.getRunningAppProcesses();
int pids[] = new int[runningApps.size()];
String processNames[] = new String[runningApps.size()];
int i = 0;
for(RunningAppProcessInfo app : runningApps) {
  pids[i] = app.pid;
  processNames[i] = app.processName;
  ++i;
}
android.os.Debug.MemoryInfo[] memInfos = activityManager.getProcessMemoryInfo(pids);
long totalPss = 0;
i = 0;
for (android.os.Debug.MemoryInfo info : memInfos) {
  Log.d(TAG, "[" + processNames[i] + "] total pss[KB] = " + info.getTotalPss());
  ++i;
  totalPss += info.getTotalPss();
}
Log.d(TAG, "TOTAL pss[KB] = " + totalPss);</runningappprocessinfo>
