title: Keyboard quickly hides and reappears on Android using Xamarin Forms
body: <p>We're trying to build a Chat App using Xamarin Forms, but we keep getting this annoying bug with the Android keyboard. Whenever the "Send" button is tapped, the focus on the Entry (text box for chatting) is lost and the keyboard disappears. That isn't what we wanted so we added this line to the TapGestureRecognizer:</p>
  
  <pre><code>messageEntry.Focus();
  </code></pre>
  
  <p>But for some reason, this doesn't happen fast enough, and often the keyboard goes down and immediately up again. This prevents users from quickly posting multiple message sequentially. Does anybody know how this can be fixed?</p>
