Expo v31 Android release build would not load JS bundle ( iOS build works on both debug and release configs)

Environment

Expo CLI 2.6.14 environment info: System: OS: macOS 10.14.2 Shell: 5.3 - /bin/zsh Binaries: Node: 8.11.4 - /usr/local/bin/node Yarn: 1.9.4 - /usr/local/bin/yarn npm: 5.6.0 - /usr/local/bin/npm Watchman: 4.9.0 - /usr/local/bin/watchman IDEs: Android Studio: 3.2 AI-181.5540.7.32.5056338 Xcode: 10.1/10B61 - /usr/bin/xcodebuild npmPackages: @storybook/react-native: ^3.2.5 => 3.4.11 expo: ^31.0.4 => 31.0.6 react: 16.5.0 => 16.5.0 react-native: https://github.com/expo/react-native/archive/sdk-31.0.1.tar.gz => 0.57.1 react-navigation: v1.0.0-beta.26 => 1.0.0-beta.26 npmGlobalPackages: expo-cli: 2.6.14

Steps to Reproduce

We have detached version of app that uses Expo v31.0.0. In iOS App works fine. (Both debug and release versions). But in Android, only debug version works. When we try to run a release build, App woudln’t load. Apparently the JS bundle is not loading. We have correctly set up release-config.

(Write your steps here:)

1. Published JS bundle usingexp publishcommand (we tried expo publish too)
2. Created an APK and launched on an Android device.

Expected Behavior

App should load.

(Write what you thought would happen.)

Actual Behavior

Only splash screen loads, then this error pops up.

Any idea why ?

I’m having the same issue after upgrading to EXPO 31. Seems like this is a know issue without any exact solution and I also tried EXPO 32 as well.

Changed PUBLISHED_URL after completed expo publish, I have updated expo-cli version to 2.6.14 but nothing works for me. Couldn’t find proper solution for this issue. It would be a great help to get an input from expo contributors to fix this issue.

Problem, in my case is that publishedUrl() method in MainActivity.java was returning the wrong value. I was previously logged in as another user, so it was most likely a leftover from that time. Not really sure.

  public String publishedUrl() {
    return "exp://exp.host/@wrong_user/project";
  }
