I am new to react native--new to app development in general in fact. I am trying to run a release build on Android emulator but the app just keeps crashing.
The debug version runs without any problem, and on iOS the same release build runs perfectly.
Here are what I did:
1.Cleaned the build folder
2.Created index.android.bundle at android/app/src/main/assets
3.Created release APK file
4.Ran on Android simulator, but keeps crashing.
I am lost here. Could someone help out and tell me where I possibly went wrong?
Here is by android/app/build.gradle:
