Error:Execution failed for task \':app:bundleReleaseJsAndAsse         


        

Answer 1

I did it like this and it works:

• Removed node modules (you can do it by running this command rm -rf node_modules)
• Run npm installl or yarn install
• Then run ./gradlew clean && ./gradlew app:assembleRelease or ./gradlew app:assembleDebug

Answer 2

First:

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

finally build:

./gradlew assembleRelease -x bundleReleaseJsAndAssets

Answer 3

Looks like you haven't made a js bundle so please make a bundle first by using command :-

 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

then in your project directory

 cd android 

Clean your gradle

 ./gradlew clean

and make a build finally

./gradlew assembleDebug

Try this. Hope it will helps you.

I was using the wrong image size (i.e image@5x.png) which caused me this problem. When I deleted that image@5x.png file...it worked!!

Answer 5

Just using ./gradlew --stop and then ./gradlew assembleRelease worked for me.

Answer 6

As of RN 0.58, for CI builds the commands is as follows:

First create directories:

mkdir -p app/build/generated/assets/react/production/release/ && mkdir -p app/build/generated/res/react/production/release

Next:

node ../node_modules/react-native/local-cli/cli.js bundle --platform android --dev false --entry-file index.android.js --bundle-output app/build/generated/assets/react/production/release/index.android.bundle --assets-dest app/build/generated/res/react/production/release --max-workers 1 --reset-cache

Also you may also want to add for your production builds according to this;

--minify true

Taken from RN's source

NOTE: We added --max-workers 1 not to deplete CI resources since they are limited to lower numbers (mem&cpu).
