Android app crashes right away in emulator/device. Error logs aren't helpful.

@grkemtneri This is not a good solution, you are generating code (index.android.bundle) inside source folder (android/app/src/) during build phase…

react.gradle tasks will generate it in build folder (build/generated/assets/react/…). But like @rahulson says, with latest version of com.android.tools.build:gradle, index.android.bundle is not copied inside APK. I downgraded to 'com.android.tools.build:gradle:4.0.2' & it’s works too.

@grkemtneri I faced same issue so I changed gradle plugin version in project gradle from 4.1.1 to 4.0.1 Then clean, rebuild and generate apk and now it is working fine

it;s a known issues that is fixed on RN version 0.63.4 https://github.com/react-native-community/releases/blob/master/CHANGELOG.md#v0634

Here is the commit with changes https://github.com/facebook/react-native/commit/53f55001afbf07494de0df064a92dfdd42f37c98

If. you don’t want to upgrade RN version just copy react.gradle file from node_modules in your project and apply that instead of the one from node_modules

react.gradle tasks will generate it in build folder (build/generated/assets/react/…). But like @rahulson says, with latest version of com.android.tools.build:gradle, index.android.bundle is not copied inside APK. I downgraded to 'com.android.tools.build:gradle:4.0.2' & it’s works too.

I have the same issue today but downgrading com.android.tools.build:gradle:4.0.2 gives me an error: No version of NDK matched the requested version

I am using com.android.tools.build:gradle:4.1.0 App build is successful but the app crashes upon start, app opens then close right away.

what to do?

thank you for your reply. I found solution npx react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle

@rahulson Thank you for your solution 😃. This worked for me. I did the same and it worked.

This is a simple cache issue. Invalidate caches from android studio and rebuild project properly. This worked for me everytime I faced this issue
