 If, when [setting up your work environment](Introduction.AndroidDevEnv.md), you&rsquo;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 suppress crash and ANR 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).

+Setting Test Butler up for working with Detox is a bit different than explained in their guides. The process, as a whole, is twofold:
 
 1. Preinstalling the test-butler-app APK onto the test device.
 1. Integrating the test-butler-lib into your own test APK, and initializing it in a custom test-runner (as explained).
 
 The library part can be easily achieved as explained there (i.e. by using Gradle&rsquo;s `androidTestImplementation`). Same goes for initialization. As for the APK, the suggested usage of Gradle&rsquo;s `androidTestUtil` is scarce when running with Detox (i.e. non-native instrumentation tests). Here&rsquo;s what to do instead.

 ##### Solution 1: Prebaked Images
 
 If you have control over the emulators' snapshots, simply download (see test-butler&rsquo;s guide) and install the test-butler APK once (e.g. use `adb install -r -t path/to/test-butler-app.apk`), and save an updated version of the snapshot. This is the best solution.
