title: event.accuracy of SensorEvent is giving garbage values
body: <p>I am trying to log the accuracy of each sensorEvent that I receive. I am using below code to log it inside the method '<code>onSensorChanged(SensorEvent event)</code>'</p>
  
  <pre><code>Log.d(TAG, "onSensorChanged: " + event.accuracy);
  </code></pre>
  
  <p>But unfortunately I am getting the garbage values( some positive numbers and some negative numbers).</p>
  
  <p>As per the <a href="http://developer.android.com/reference/android/hardware/SensorManager.html#SENSOR_STATUS_ACCURACY_HIGH" rel="nofollow">android documentation</a>, I should be getting values in range [-1,3].</p>
  
  <p>Any idea why is this happening?</p>
