title: Remove the error indicator from a previously-validated EditText widget
body: <p>I am using an EditText widget, and I am validating it with the <code>setError()</code> method of EditText and it validates correctly. </p>
  
  <p>But I have an button in the same screen that redirects to another activity. And when I press back button and come back to the screen the validation still appears.</p>
  
  <p>So on the activity <code>OnPause</code> event I want to remove the validation of the EditText. How is it possible.</p>
