How to get CPU usage by Running Apps

I am working on an App, where I need to show the CPU usage as per running applications(just like a Task manager).

I have followed this post, Get CPU usage, but it demonstrates the total CPU usage. Here it has used the following code to read the CPU stats,

RandomAccessFile reader = new RandomAccessFile("/proc/stat", "r");

I want to get cpu usage of all individually running apps. So far, I've been able to fetch the list of all running applications,

      ActivityManager activityManager = (ActivityManager)
                      getSystemService(ACTIVITY_SERVICE);

    List<RunningAppProcessInfo> listOfRunningProcess = activityManager
                    .getRunningAppProcesses();

Now I want to get the CPU usage for these applications.

Use top command and Execute it by using Runtime.execute("your top command") This will give you a String and you have to parse it to get each app CPU usages.

look at here for more on Top command.

Well you can use the linux top command to get the memory usage for each process (PID).

You can find the complete implementation here.
