title: Can i start an android service without activity or GUI?
body: <p>My target Android is 4.1.2. I created an simple android service which will show Toast on boot. But this application should not have any GUI. I was success running this service only from an activity which show GUI on start.</p>
  
  <pre><code>public class MyServices extends Service {
  private MediaRecorder recorder = null;
  @Override
  public IBinder onBind(Intent intent) {
  
      return null;
  
  }
  public int onStartCommand(Intent intent, int flags, int StartId)
  {
  
      Toast.makeText(this, "Service Started", Toast.LENGTH_LONG).show();
  
  }
  }
  </code></pre>
