Espresso: Appnotidleexception

I am continuously getting this error when I land on a page. What could be the solution to this? android.support.test.espresso.AppNotIdleException: Looped for 4539 iterations over 6

Solution 1:

It might occur due to any UI element which is creating itself infinitely. For example, you have a Custom ProgressBar or Snackbar which is set to invisible/gone in xml and you are setting it visible in java code. But it might re-paint itself in invisible/gone state also due to ill-written code. So, go through any Custom UI elements as well if you have any.

Solution 2:

It's very likely because you didn't turn off the following 3 settings in you developer options:

• Window animation scale
• Transition animation scale
• Animator duration scale

If that is not the case something seems to be interacting with your screen while the test is running.
