React Native + Android：发布版本“无法获取BatchedBridge”吗？

Question

I'm trying to prepare my app for release, but when I run adb install android/app/app-release.apk or download my Beta build from the app store, it complains about with Unfortunately App, has stopped

I ran adb logcat and I see this:

01-13 22:46:03.949 13326 13351 E         : Unable to load script from assets: index.android.bundle

Is this because my release build is trying to run in debug mode?? I thought it would only show that error if it's still trying to look for localhost:8081.

Looks like I had to run cd android && ./gradlew assembleRelease first

Notes: releasing android builds 1) cd android && ./gradlew assembleRelease 2) build > generate signed APK 3) connect your phone 4) run adb install android/app/app-release.apk to test that the release build works on a device 5) run adb logcat to view the log in case anything is broken
