title: Set text in AccessibilityNodeInfo
body: <p>I'm developing an Android Accessibility Service. I got an <a href="http://developer.android.com/reference/android/view/accessibility/AccessibilityNodeInfo.html" rel="noreferrer">AccessibilityNodeInfo</a> that represents an EditText. Is possibile to edit the contained text?</p>
  
  <p>I tried with <code>mynode.setText("aaa")</code> but i get <code>IllegalStateException</code> as described in official documentation <a href="http://developer.android.com/reference/android/view/accessibility/AccessibilityNodeInfo.html" rel="noreferrer">http://developer.android.com/reference/android/view/accessibility/AccessibilityNodeInfo.html</a></p>
  
  <p>Any ideas?
  Thanks</p>
