title: Android permissions in manifest
body: <p>I written 2 apps.</p>
  
  <p>First app has only service and second one has an Activity. I am starting the service in 1st app from activity in 2nd app. In Service I am modifying audio settings so, I need <code>android.permission.MODIFY_AUDIO_SETTINGS</code> in manifest.</p>
  
  <p>My question is <strong>in which manifest file I have to add this permission</strong>. Why I am asking because if I add this permission in Service app manifest I am getting warning <strong>Exported service does not require permission</strong>.</p>
  
  <p>If anybody know it, post the solution.</p>
