 ### 8. Test Butler Support (Optional)
 
-If, when [setting up your work environment](Introduction.AndroidDevEnv.md), you've selected Google emulators with an AOSP image as the test target - as recommended, **we strongly encourage** you would also integrate [Test Butler](https://github.com/linkedin/test-butler): in the very least - in order to supress crash & ANR's dialogs. They are a soft spot in UI testing on Android, all around, as - when displayed, they make the UI entirely inaccessible (and thus cause tests to fail in bulks).

-By default, Detox is designed to ignore `setInterval` and will only wait for `setTimeout` of up to 1.5 seconds. If you have an endless polling loop with short intervals implemented with `setTimeout`, switch the implementation to `setInterval`. If possible, avoid agressive polling in your app altogether, the poor single JavaScript thread we have doesn't like it.
