I have added 2 more buildTypes in my build.gradle file staging & prestaging alongside with release. When I build and run the release buildType it works fine on the real device, but when I build and run staging or prestaging builds both crashes on startup. The crash report on the device shows the following error:
All the builds work without any issue on iOS
My staging and prestaging build failed because the bundle were not packaged correctly as the error says. This is because when building Android app react-native only add the bundle to the package if the buildType name contains the word release. The simple solution for this is to name the buildType's in such a way that the names contain the word release. I renamed the buildType's to stagingRelease and prestagingRelease.
