title: Location object passed into onLocationChanged is null?
body: <p>I have an activity that implements LocationListener in my application and my onLocationChanged method has been working perfectly up until recently.  For some reason the Location object being passed into the method is null.  My question is, why is it null?  Does it pass in a null object if it cannot acquire a location?</p>
  
  <p>My GPS is on and I have it set to pull a location from the GPS, and I know my GPS can get a fix on me as I used Maps and had it locate me.</p>
  
  <p>Also, I have the permission for my app set as:</p>
  
  <pre><code>&lt;uses-permission android:name="android.permission.INTERNET" /&gt;
  &lt;uses-permission android:name="android.permission.CAMERA" /&gt;
  &lt;uses-permission android:name="android.permission.ACCESS_GPS" /&gt;
  &lt;uses-permission android:name="android.permission.ACCESS_LOCATION" /&gt;
  &lt;uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /&gt;
  &lt;uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /&gt;
  </code></pre>
  
  <p>I don't believe permissions is the issue though, as my activity was working beforehand and I have not altered the permissions since then.</p>
  
  <p>Here is the code that determines the provider of the location object:</p>
  
  <pre><code>String locationProvider = this.mLocationManager.getBestProvider(mLocationCriteria, true);
  this.onLocationChanged(this.mLocationManager.getLastKnownLocation(locationProvider));
  </code></pre>
  
  <p>Here is the LogCat output of the error:</p>

  <p><code>[UPDATE]</code> I have tested the same code on another device (an HTC MyTouch 3G to be precise) and it works flawlessly with the GPS, however on my Motorola Droid it crashes.</p>
