title: Autocomplete Google maps API returns NULL
body: <p>I am a newbie to android and google maps. Basically, I want to provide a search bar besided my mapview to users. The search bar should enable user to search for restaurants. 
  I tried using the google autocomplete API . However, when I type one character to it, it returns null . </p>
  
  <p>The code for my layout xml is : </p>
  
  <pre><code>&lt;fragment
          android:id="@+id/place_autocomplete_fragment"
          android:layout_width="match_parent"
          android:layout_height="wrap_content"    android:name="com.google.android.gms.location.places.ui.PlaceAutocompleteFragment"/&gt;
  </code></pre>
  
  <p>And I am simply loading this xml from my fragment class. 
  Do I need to do anything in my fragment class to make this work?</p>
  
  <p>Thanks a lot.</p>
