title: Issue with black box appearing on Android app screen
body: <p>Attached is a screen of my android app. It usually works perfect, but sometimes when I press an item on the menu, I get a small black box appearing (toast?).</p>
  
  <p>Does anyone know why this occurs and how can I make it not appear again?</p>
  
  <p>Here is the screenshot of the issue.
