Set text in AccessibilityNodeInfo

Question

I'm developing an Android Accessibility Service. I got an AccessibilityNodeInfo that represents an EditText. Is possibile to edit the contained text?

I tried with mynode.setText("aaa") but i get IllegalStateException as described in official documentation http://developer.android.com/reference/android/view/accessibility/AccessibilityNodeInfo.html

Any ideas? Thanks

You can use ACTION_SET_TEXT for >= android 21. Here is the example of it:

AccessibilityNodeInfo source = event.getSource();
if (source != null & event.getClassName().equals("android.widget.EditText")) {
    Bundle arguments = new Bundle();
    arguments.putCharSequence(AccessibilityNodeInfo
            .ACTION_ARGUMENT_SET_TEXT_CHARSEQUENCE, "android");
    source.performAction(AccessibilityNodeInfo.ACTION_SET_TEXT, arguments);
}
