title: SensorEventListener in separate thread
body: <p>This seems like a basic question, but after searching for a while and playing with it, I've come to the point where some help would be appreciated.  I would like to have a SensorEventListener run in a separate thread from the UI, so that computations that need to occur when events come in won't slow down the UI.  </p>
  
  <p>My latest attempt looks like:</p>
  
  <pre><code>class SensorThread extends Thread {
      SensorManager mSensorManager;
      Sensor mSensor;
  
      public void run() {
          Log.d( "RunTag", Thread.currentThread().getName() ); // To display thread
          mSensorManager = (SensorManager)getSystemService( SENSOR_SERVICE  );
          mSensor = mSensorManager.getDefaultSensor( Sensor.TYPE_ACCELEROMETER );
          MySensorListener msl = new MySensorListener();
          mSensorManager.registerListener(msl, mSensor, SensorManager.SENSOR_DELAY_UI );
      }
  
      private class MySensorListener implements SensorEventListener {
          public void onAccuracyChanged (Sensor sensor, int accuracy) {}
          public void onSensorChanged(SensorEvent sensorEvent) {
              Log.d( "ListenerTag", Thread.currentThread().getName() ); // To display thread
          }
      }
  </code></pre>
  
  <p>In the activity's (or service's) onCreate(), I create a SensorThread object and call its start() method.  As you would expect, the debug log shows the "RunTag" entry in the new thread.  But onSensorChanged()'s "ListenerTag" is running in the main thread, even though its object is instantiated in the new thread.  How do I change that?  </p>
