Process 'command 'npx.cmd'' Finished With Non-zero Exit Value 1 React Native Build Problem

I am working on react native. When i try to create a build of android using gradlew assembleRelease then getting an * What went wrong: Execution failed for task ':app:bundleRelea

Solution 1:

use cd android

after that use this ./gradlew clean

and for apk ./gradlew assembleRelease -x bundleReleaseJsAndAssets

or use this for aab ./gradlew bundleRelease -x bundleReleaseJsAndAssets

Try these commands and please tell me if it works

Solution 2:

For me, I had to run npm run android once and then ./gradlew assembleRelease worked

UPDATE: Run following command and see output log to find the bug

npx react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res

Solution 3:

Personally, I had to run the app form within Android Studio. That gave me a clearer error message which allowed me to fix the issue.

The error in my case had to do with entryFile: "index.android.js", inside app/build.gradle. I had to change it to index.js since that was the entry point in my RN project.
