title: PlaceAutoComplete not working in signed apk
body: <p>I have a very strange issue. PlaceAutoComplete was working fine in my debug apk. But now in my signed apk, the autocomplete fragement shows, but if i type anything it just returns back to the previous screen without doing anything. Here is the snippet from my MainActivity:</p>
  
  <pre><code>                    try {
  
                          Intent intent =
                                  new PlaceAutocomplete.IntentBuilder(PlaceAutocomplete.MODE_FULLSCREEN)
                                          .build(MainActivity.this);
  
                          startActivityForResult(intent, PLACE_AUTOCOMPLETE_REQUEST_START);
                      }catch(GooglePlayServicesRepairableException e){
                          // TODO: Handle the error.
                          Toast.makeText(MainActivity.this, "Error in GooglePlayServicesRepairable", Toast.LENGTH_LONG).show();
                      }catch(GooglePlayServicesNotAvailableException e){
  
                          Toast.makeText(MainActivity.this, "Error in PlayServiesNotAvbl", Toast.LENGTH_LONG).show();
                          // TODO: Handle the error.
                      }
  </code></pre>
  
  <p>Btw, none of the Toast messages are coming, so I'm not sure if the problem is there.</p>
  
  <p>My AndroidManifest file is as below for the permissions</p>
  
  <pre><code>&lt;uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /&gt;
  &lt;uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /&gt;
  &lt;uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/&gt;
  &lt;uses-permission android:name="android.permission.INTERNET" /&gt;
  &lt;uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/&gt;
  </code></pre>
  
  <p>(Not sure if ACCESS_NETWORK_STATE and READ_GSERVICES are required. I added these 2 after reading here on StackOverflow that it solved some users problem</p>
  
  <p>This is really driving me nuts. Is there any library that I need to add to my production apk? The size seems almost 1 mb less than the debug one....</p>
  
  <p>Thanks in advance</p>
  
  <p>Note that API key is fine as the same works in debug mode</p>
