React Native Build APK Generate release mode APK for React-Native project to publish on PlayStore

Good Day All! I hope you are doing Good.

From last couple of days, Me and my friends were doing comparative study of ionic3 and react-native. During that period, we were struggling to generate release mode APK for React-Native project.

Finally, we came across following solution:

Create and then copy a keystore file to android/app

keytool -genkey -v -keystore mykeystore.keystore -alias mykeyalias -keyalg RSA -keysize 2048 -validity 10000

Setup your gradle variables in android/gradle.properties

MYAPP_RELEASE_STORE_FILE=mykeystore.keystore
MYAPP_RELEASE_KEY_ALIAS=mykeyalias
MYAPP_RELEASE_STORE_PASSWORD=*****
MYAPP_RELEASE_KEY_PASSWORD=*****

Add signing config to android/app/build.gradle

android {
signingConfigs {
release {
storeFile file(MYAPP_RELEASE_STORE_FILE)
storePassword MYAPP_RELEASE_STORE_PASSWORD
keyAlias MYAPP_RELEASE_KEY_ALIAS
keyPassword MYAPP_RELEASE_KEY_PASSWORD
}
}
buildTypes {
release {
signingConfig signingConfigs.release
}
}
}

Generate your release APK:

cd android && ./gradlew assembleRelease

Your APK will get generated at: android/app/build/outputs/apk/app-release.apk

Thanks for the tutorial! I've put up an article containing several errors that I encounter when building a release APK for React Native pretty frequently.

 

I love your article, thanks

 

Thanks mrcflorian

 

Hi Zilu. Follow your instructions, obtain error:

Unable to load script. Make sure you're either running a Metro server (run 'react-native start') or that your bundle 'index.android.bundle' is packaged correctly for release.

 

don't run debug version, to create apk release version first you must run:
npx react-native run-android --variant=release
or
react-native run-android --variant=release

Then APK can be found in android/app/build/outputs/apk/release

 

You get this error after running which command?
Could you please provide more details.

 

Hello my friend, i did the procedure above, but dont work, it show me the next message :
"Deprecated Gradle features were used in this build, making it incompatible with Gradle 6.0"
Could you Please help me whit that.

 

Thanks for the article. The app was built without errors. But when I install it on my device and run the app, App keeps stopping with the message "App keeps stooping"

 

Hi Zilu,

If you are in Windows the last command is cd android && gradlew assembleRelease

whitout the "./"
