[Bug] [RN] [AD] index.android.bundle not found

For some reason I had import com.facebook.react.BuildConfig; in my MainAplication file (I guess due to some smart ass auto import fixing feature of IntelliJ), and therefore BuildConfig.DEBUG was set to false. Because of this:

    public boolean getUseDeveloperSupport() {
      return BuildConfig.DEBUG;
    }
React Native was always trying to load index.android.bundle from the app pacakge, not from the dev server. Removing the import com.facebook.react.BuildConfig line fixed the issue for me
