How to get process memory consumption in Android

Question

I want to know the memory consumption of an application A through Application B. I am aware of all the techniques that have been discussed on this website. However, none of them are working for me. My scenario is, I have already implemented a code that can monitor CPU consumption of any specific application through top command. However, the top command only provides VSS and RSS, while i am interested in PSS and USS. One way to get these values is through procrank. However, I am not sure if procrank command can be executed on smartphone as I have tried process p2 = Runtime.getRuntime().exec("procrank"); but its not working. (EDIT: Works on Android emulator (not smartphone). Can someone please guide me how to get PSS and USS through Application id or name, which I have already taken through top command.

Dianne Hackborn, who is on the Android team at Google, answers this question really well [here](http://stackoverflow.com/questions/2298208/how-to-discover-memory-usage-of-my-application-in-android/2299813#2299813). — Michael, Mar 10 '13 at 22:29
Yes, I have read this article and provided a reference in my post. I am looking for some code that can provide me PSS and USS info, using memeoryinfo() or procrank on android. Can you help? — atta, Mar 10 '13 at 23:04
You might be better off explaining why you want to get the memory usage info for another app. I suspect there's a better tool for your use-case than whatever you're trying to do. — Michael, Mar 11 '13 at 05:50
Actually I am creating a profiler that will monitor applications CPU, Memory, Energy consumption and perform some actions accordingly. — atta, Mar 11 '13 at 21:25

I know the question is old, I will suggest something..

Firstly get root privilege in console with

Process process = Runtime.getRuntime().exec("su");

Then write your command with root access
```
su <--command-->
```

Read stream output

try {
  Process process = Runtime.getRuntime().exec("su");         
  DataOutputStream dataOutputStream = 
                           new DataOutputStream(process.getOutputStream());
  if (dataOutputStream != null) {
      dataOutputStream.writeBytes("procrank\n");             
      dataOutputStream.flush();
      BufferedInputStream bufferedInputStream = 
                           new BufferedInputStream(process.getInputStream());
      byte[] bff = new byte[bufferedInputStream.available()];
      bufferedInputStream.read(bff);
  }
} catch (Exception e) {
}
