title: Facebook setInitialize is deprecated but removing it causes inflating error
body: <p>As suggested here:</p>
  
  <blockquote>
    <p>The Facebook SDK is now auto initialized on Application start. If you
    are using the Facebook SDK in the main process and don't need a
    callback on SDK initialization completion you can now remove calls to
    FacebookSDK.sdkInitialize. If you do need a callback, you should
    manually invoke the callback in your code.</p>
  </blockquote>
  
  <p><code>Facebook.setInitalizer(context)</code> is now deprecated. The problem is that when I remove the line: <code>Facebook.setInitalizer(context)</code> as suggested I get an Inflating error on: <code>com.facebook.login.widget.LoginButton</code>:</p>
  
  <pre><code>&lt;com.facebook.login.widget.LoginButton
      android:id="@+id/signin_activity_login_button_fb"
      android:layout_width="240dp"
      android:layout_height="wrap_content"
      ...
  /&gt;
  </code></pre>
  
  <p>Error:</p>
  
  <pre><code>android.view.InflateException: Binary XML file line #22: Binary XML file line #22: Error inflating class com.facebook.login.widget.LoginButton
  </code></pre>
  
  <p>When I return the initalizer the error is gone. What should I do.</p>
  
  <p>Also Gradle:</p>
  
  <pre><code>compile 'com.facebook.android:facebook-android-sdk:[4,5)'
  </code></pre>
