Question

I save all the tasks in the activity manager
by using this code

List<ActivityManager.RunningAppProcessInfo> list = am.getRunningAppProcesses();

now, I can get some information from this list like for example the pid of each task etc

but how can I find out how much memory each tasks uses? is it possible to do so from having obtained the above list?

thanks in advance

Use ActovityManager.getProcessMemoryInfo() and iterate the array.

ActivityManager activityManager = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
        for (ActivityManager.RunningAppProcessInfo info : activityManager.getRunningAppProcesses()) {
            Debug.MemoryInfo[] memInfo = activityManager.getProcessMemoryInfo(new int[]{info.pid});
            for (Debug.MemoryInfo memoryInfo : memInfo) {
                //
            }
        }
