Espresso AppNotIdleException

I have tests made using Espresso and they stops in the begining, and I have no animation in my app. The exception points on the first test tasks when it has to type an email in EditText during registration. Maybe you know what is the problem?

The error log:

8862-8878/com.heimat.ahududu W/System.err: android.support.test.espresso.AppNotIdleException: Looped for 21 iterations over 60 SECONDS. The following Idle Conditions failed ASYNC_TASKS_HAVE_IDLED.
