android ps 출력이 제대로 될까?

android 에서 ps를 호출하여 어떤 프로세서들이 동작하는지 확인 할 수 있을까?
권한이 없는건 아닐까 테스트 해보았습니다.

ps 의 경우 user버전에서 동작할까?

결론 : 잘 동작함

private void test100()
{
 Utils.RunExec("ps");  
}

     public static String RunExec(String cmd)
     {
      String result = null;
      Runtime runtime = Runtime.getRuntime(); 
      java.lang.Process process; 
      try { 
              process = runtime.exec(cmd); 
              BufferedReader br = new BufferedReader(new InputStreamReader(process.getInputStream())); 
              String line ; 
              while ((line = br.readLine()) != null) { 
               Log.i("test",line);
               if( result == null ) result = line;
               else result = result + line;
              } 
      } catch (Exception e) { 
              e.fillInStackTrace(); 
              Log.e("Process Manager", "Unable to execute top command"); 
      }
      return result;
     }
