title: Viewing and Modifying all TextViews across the device?
body: <p>Sorry for the poorly worded title, allow me to explain.</p>
  
  <p>I have an idea for a translator app that will translate any text across all apps. Is it possible to create a listener that can watch all apps, and whenever a TextView is created, modify the content if the content contains a certain keyword?</p>
  
  <p>Thanks!</p>
