title: Does Timer run on a background thread? Inconsistent executions with timer.schedule()
body: <p>I've been working on an app to send sensor data via UDP. I have implemented a UDP client with an AsyncTask, and have created a Timer to execute this AsyncTask (send UDP packets) at a fixed interval.</p>
  
  <p>However, I've noticed that there is intermittent lag in outputting udp packets, indicating that the scheduled executions are being held up at times. I've noticed that if I play with the UI (slide the notification bar up and down/have a notification pop up), the scheduled executions are held up.</p>
  
  <p>This leads me to wonder if the Timer is indeed running on a background thread or not? The developer docs seem to indicate that it does, however it seems to get held up with UI events.</p>
  
  <p>My code is below, perhaps there is an issue with my implementation? My app is currently listening for sensor data, and outputting accel in X direction via udp. I am receiving the packets on a simple python server.</p>
