These methods have not been changed for a long while. Have you tried to change 
the index to 1 or 2 etc?

Ok there is a huge difference - I am testing a Dialog fragment view.
So the first step is click on  a button which launches the fragment (extends 
DialogFragment)
Then the rest is performed there.
Now solo.typeText(0, "testmed"); WORKS!!!
Why the solo.clearEditText(0); is not working ?
