Performing a click on an AlertDialog button throws "InjectEventSecurityException: Injecting to another application requires INJECT_EVENTS permission"

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create an activity with an AlertDialog. Don't give the button an ID. 
Instead, use the defaults, android.R.id.button1 and android.R.id.button2.

2. In the test, attempt to click on the negative button using

onView(withId(android.R.id.button2)).perform(click());

3. an Exception is thrown.

What is the expected output? What do you see instead?

I expect the dialog to dismiss itself, instead an Exception is thrown:

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

espresso-contrib-1.1-bundled.jar on Mac OS X version 10.9 running Android 4.4.2 
in an Intel x86 w/ HAXM emulator. Using Android Studio IDE.

Please provide any additional information below.

Adding the permission "android.permissions.INJECT_EVENTS", a warning is shown 
in the manifest "Permission is only granted to system apps" but compiles anyway.

Same error is shown (after many tests) when using,

onView(withText(R.string.cancel)).perform(click());

I'm facing this same issue intermittently with menu items in the action bar.

Same issue here, but with Robotium. This may be an issue of the x86 system 
image and not of espresso.

Same here on HW device with KitKat 4.4.2. Anims off.

This means that something (e.g. a system ANR dialog or keyguard) is blocking 
the view you're trying to click. This is outside Espresso scope and should be 
fixed on a device setup level.

At least in my case this only happens with menu items on the action bar. It's 
intermittent, but easily reproducible. I doubt there's any ANR involved, 
otherwise I'd probably see it with regular views. No?
