title: change process priority in android
body: <p>How to change process priority in Android? I have found process description and description of it's priorities in android docs</p>
  
  <p><a href="http://developer.android.com/guide/topics/fundamentals/processes-and-threads.html" rel="noreferrer">process and thread description</a></p>
  
  <p><a href="http://developer.android.com/reference/android/app/ActivityManager.RunningAppProcessInfo.html#IMPORTANCE_BACKGROUND" rel="noreferrer">process priorities</a></p>
  
  <p>but I have found nothing on changing process priority by some method.</p>
  
  <p>ps: I need this to test only some feature of application which is connected with process priority and it won't be used in program.</p>
  
  <p>The only way I see is to try to change the priority via <strong>importance</strong> field, but it's a bad idea I guess.</p>
