When running Android with Expo - ReactInstanceManager is null

[adam-stasiak]

Description

In my case everything is working fine for iOS but for Android I have white screen displayed and next app turn off. I noticed that DetoxServerUrl is different inside first log and the another (adb command).

Steps to Reproduce

Follow the official guide for Android. Run tests from command line when Expo XDE is on.

@LeoNatan Could you give any advice how to workaround this issue? Huge blocker for my team.

Sorry, I am the iOS guy. 😜
We are having some major Android issues and are looking into them. We have not had time to explore Expo, so I cannot say wether those issues are related or not. Pinging @rotemmiz
