Issue running project in Android Studio after detaching


#1

Hi Everyone, I’ve been using XDE but need to detach now and having some major problems to getting it working now in android studio.

Env Details:
Windows: 10
Android Studio: 3.1.4
Node.js: 8.11.3
NPM: 5.6.0
expo: 1.1.0-beta.5
exp: 57.0.0

Steps to replicate issue

  1. Open upe Expo XDE and create new project
    -> Run and test that it works in simulator in android studio (yes it works)

  2. Open up app.json and add
    “android”: {
    “package”: “com.yourcompany.yourappname”
    }

  3. cmd line into project and ‘exp detach’

  4. ‘exp start’ (no errors given initially and gives url)

  5. Open project in Android Studio (takes time with “Building ‘android’ Gradle project info”)

    • Build completes successfully with all oks.
  6. Now in android studio I go to Run on the top menu, then select Run ‘app’

  • emulator screen goes white doesnt change and under the Run output I get these errors
  • Also once all this was done I looked back in the cm line where I ran exp start and it now says “Metro Bundler failed to start. (code: EPERM)”
