Go back to debugging after created release version with react-native bundle (Android)

问题

So I have created my Application using React native and just produced my first release-build. My problem now is that I can't get back to react natives debug-mode.

By following the documentation, this is what i did.

react-native bundle --platform android --dev false --entry-file index.android.js --bundle-output android/app/src/main/assets/

This code generated the bundled index.android.bundle and index.android.bundle.meta

Now every time I execute react-native run-android, the javascript code-base wont update the application and I am not able to access the development(shake) menu in my app.

If I run react-native bundle again, the code will update.

I guess this is a simple issue, but can't find any information how to return so the app isn't using the bundled version anymore.

回答1:

• Delete assets folder in app/src/main/
• Remove this import line if exist : "import com.facebook.react.BuildConfig;" in MainApplication.java
• Run "react-native run-android"

And boom!

回答2:

My quickest way is openning the file: $projectRoot\android\app\src\main\java\com\movies\MainApplication.java, going to the code like:

public boolean getUseDeveloperSupport() {
 return false; //it was changed to false from BuildConfig.DEBUG when released
}

then changing the false to true to make the debug menu available again.

It happens with wrong import statement in MainApplication.java, You have to check if any statement like import com.facebook.react.BuildConfig; is in the imports. If so, remove that and run react-native run-android

No need to delete assets folder
