What version of the product are you using? On what operating system?

espresso-standalone/espresso-1.0-SNAPSHOT-bundled.jar
Nexus 4
Nexus 4 emulator image

Please provide any additional information below.

The problem was first observed running tests on an LG Nexus 4. The error was 
then reproduced in an emulator running the Nexus 4 preset (hardware keyboard 
not enabled).
Turning on the hardware keyboard option works around the crash (in the 
emulator). Using a different resolution emulator image (ex. 480x854) also seems 
to avoid the problem.

It appears that Espresso is not waiting for the completion of the 
closeSoftKeyboard() and the perform(click()) is being sent to the system UI 
view (soft keyboard) instead of the Button, as desired.

I am running into the same problem with the Nexus 5 and the softkeyboard being 
open, before the button click.  I enter text into the edit text field then 
closeSoftKeyboard then preform click.  I put a 100 ms sleep in now for a short 
term fix and the test now pass.

        onView(withId(R.id.face_amount)).perform(typeText(testFaceAmt), closeSoftKeyboard());

        try {
            Thread.sleep(100);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }

        onView(withId(R.id.calculate_button)).perform(click());

This is likely due to animations delaying the close of the soft keyboard. Our 
deployment instructions say:

To avoid flakiness, we highly recommend that you turn off system animations on 
the virtual or physical device(s) used for testing.

Please try that.

System animations were turned off. Bug happens regardless.
