Unable to use local version of React Native

[MarkOSullivan94]

• I have reviewed the documentation
• I have searched existing issues
• I am using the latest React Native version

Currently trying to make changes to the React Native source to help improve the share functionality for Android (or at least try to).

Was following this guide: https://facebook.github.io/react-native/docs/building-from-source.html#3-adding-the-reactandroid-project

I got to this step: https://facebook.github.io/react-native/docs/building-from-source.html#3-adding-the-reactandroid-project

Unfortunately after running react-native run-android, I was no longer getting a successful build.

app build.gradle - https://github.com/MarkOSullivan94/ReactNativeShareExample/blob/master/android/app/build.gradle

settings.gradle - https://github.com/MarkOSullivan94/ReactNativeShareExample/blob/master/android/settings.gradle

Environment

Environment:
OS: macOS High Sierra 10.13.3
Node: 10.1.0
Yarn: Not Found
npm: 5.6.0
Watchman: 4.9.0
Xcode: Xcode 9.2 Build version 9C40b
Android Studio: Not Found

Packages: (wanted => installed)
react: 16.3.1 => 16.3.1
react-native: github:MarkOSullivan94/react-native#master => 1000.0.0

Steps to Reproduce

Clone my example project which I was building to test out the changes to the RN source: https://github.com/MarkOSullivan94/ReactNativeShareExample

Then run it with react-native run-android.

Expected Behavior

The app would build successfully.

Actual Behavior

 react-native run-android

Still requires community attention

Perhaps @dulmandakh or @gengjiawen can help.

[gengjiawen]

@MarkOSullivan94 Can you upgrade the project to to 0.57.rc3. The forked react-native now is not working on windows.

[gengjiawen]

Okay, using circleci find out the reason, in setting.gradle line 6, it should be , not =

project(':ReactAndroid').projectDir = new File(
    rootProject.projectDir = '../node_modules/react-native/android'
)

[gengjiawen]

Actually you project has inconsistency. You may need to cleanup. For your project now, You need to add to build.gradle

        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }
