How to Generate/Build React Native Debug APK
What’s the difference between Debug APK and Release APK:
- Debug APK is only for testing and installable other devices by sending APK file directly, it cannot be published to Play Store
- Release AAB/APK can be published to Play Store
Option 1: for normal React Native app:
react-native bundle --dev false --platform android --entry-file index.js --bundle-output ./android/app/build/intermediates/assets/debug/index.android.bundle --assets-dest ./android/app/build/intermediates/res/merged/debug (cd android && ./gradlew assembleDebug)
Option 2: for Rocket.Chat.ReactNative:
yarn react-native bundle --dev false --platform android --entry-file index.js --bundle-output ./android/app/build/intermediates/merged_assets/debug/out/index.android.bundle --assets-dest ./android/app/build/intermediates/res/merged/debug (cd android && ./gradlew assembleDebug)
Output APK will be in
Now you can install app manually or use
adb install android/app/build/outputs/apk/debug/app-debug.apk
Info: The Debug Key is generated as follows:
Keystore name: "debug.keystore" Keystore password: "android" Key alias: "androiddebugkey" Key password: "android" CN: "CN=Android Debug,O=Android,C=US"
We use app signing by Google Play and to ensure support for Android App Bundles, so we use an upload key and not an app signing key.
- Get the upload key keystore (or, if not yet exist, generate then save it)
Note: This needs to be done only once per organization. Soluvas already have a
soluvas-upload.keystore with a password, stored in Soluvas’s Google Drive.
keytool -genkey -v -keystore soluvas-upload.keystore -alias upload -keyalg RSA -keysize 2048 -validity 10000
2. Add upload key keystore file to project
soluvas-upload.keystore (must be gitignore-d!) into the
android/app directory in your React Native project folder.
3. Set ./android/gradle.properties
KEY_PASSWORD on ./android/gradle.properties with your credentials:
KEYSTORE=soluvas-upload.keystore KEY_ALIAS=upload KEYSTORE_PASSWORD=*** KEY_PASSWORD=***
4. Generate release AAB / APK
Recently, AAB is recommended over APK.
# or: bundlePlayRelease (cd android && ./gradlew bundleRelease)
If you want to generate APK instead of AAB:
(cd android && ./gradlew assembleRelease)
If that’s succesful, the release AAB/APK creation process is done. You can find the generated:
- AAB at
- APK at
This is the actual app, which you can send to your phone or upload to the Google Play Store. Congratulations, you’ve just generated a React Native Release Build AAB/APK for Android.

Future Development in Flutter
Currently Lovia & Miluv uses React Native because Rocket.Chat mobile client is in React Native (Electron desktop client also uses React). We will be migrating to Flutter in the future.
Play Store Warnings & Best Practices
This APK contains Java/Kotlin code, which might be obfuscated. We recommend you upload a deobfuscation file to make your crashes and ANRs easier to analyze and debug. Learn More
