title: Android Google plus Sign out button looks different from sign in button in Google tutorial docs
body: <p>I am following the steps mentioned in Google developers site to implement sign in and sign out in my app.</p>
  
  <p>The code to add the sign-in and sign-out button as mentioned there is:</p>
  
  <pre><code>&lt;!-- sign-in button --&gt;
  &lt;com.google.android.gms.common.SignInButton
      android:id="@+id/sign_in_button"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content" /&gt;
  
  &lt;!-- sign-out button --&gt;
  &lt;Button
      android:id="@+id/sign_out_button"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:text="Sign Out"
      android:visibility="gone" /&gt;
  </code></pre>
  
  <p>In the sample mentioned over there, the sign out button looks very different(and odd) from the sign out button.</p>
  
  <p>Is this because the sign out button is not taken from <code>com.google.android.gms</code>?</p>
  
  <p>Is there a proper sign-out button available in com.<code>google.android.gms</code>?</p>
