title: Alert user when EditText limit exceeded
body: <p>I'd like to limit an EditText field to 150 characters, which I can do quite easily. However, I also need to alert the user when they try to exceed that limit, either by typing (i.e. the 151st character) or by pasting more than 150 characters.</p>
  
  <p>What's the best way to go about this?</p>
