I am having problems matching a message with a toast in one of my actions. In others, it works without any problems, but it does not work in this. I do not know of any special layout changes that can cause this behavior.
I get the following exception:
java.lang.RuntimeException: Waited for the root of the view hierarchy to have window focus and not be requesting layout for over 10 seconds. If you specified a non default root matcher, it may be picking a root that never takes focus. Otherwise, something is seriously wrong.

I check the toast message as follows (which does NOT work):
onView(withText(R.string.act_preferences_context_empty)) .inRoot(withDecorView(not(is(mActivityRule.getActivity().getWindow().getDecorView())))) .check(matches(isDisplayed()));
However, when I check the toast like this, it works :
onView(withText(R.string.act_preferences_context_empty)) .inRoot(not(isFocusable())) .check(matches(isDisplayed()));
Can anyone explain this behavior? Thanks.
