I tried to generate an unsigned apk to install on my other device.
I tried
cd android
then
gradlew assembleRelease
I got an "app-release-unsigned.apk" at android\app\build\outputs\apk\release
I transfered this "app-release-unsigned.apk" to my other android device. Turned on the "install unknown apps". Then installed the "app-release-unsigned.apk", but I got error
App not installed.
Did I missed any steps? Why can't I install this app? I thought for a release, the apk should have everything it need to run my app.
Try this and make sure you have created assets folder :
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 \
&& cd android \
&& ./gradlew clean\
&& ./gradlew assembleDebug
After this you can find your debug apk in
/android/app/build/outputs/apk/debug
Hope it will work .

i can't build apk and I have this error
Try clean build:
Delete node_modules
npm cache clean –force
npm install
cd android
gradlew clean
gradlew assembleRelease -x bundleReleaseJsAndAssets
if this fails: in root of project:
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
You can track this issue here: https://github.com/facebook/react-native/issues/28510
I fixed it, it was because one of my folder had a space and it tryed to run it as a command
I have a react native project. it works fine on android. but can not create debug apk file of this project.
first run this command in your terminal
npm run 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/
after this go inside your android folder by running this command
cd android && ./gradlew assembleDebug
then you can get your apk from this location
app/build/outputs/apk/debug/app-debug.apk
I have tried making new bundle using command below but still no luck.
react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/shell-app.bundle --assets-dest android/app/src/main/res
My app is expo ejected app
I don't know about iOS , but on Android try the following
Clean your build
in your project directory execute
cd android && gradlew clean
Increase your build number.
go to {ProjectDirectory}/android/app/build.gradle
android {
defaultConfig {
versionCode 1 // increase this value by one
}}
finally build your release
in your project directory execute
cd android && gradlew assembleRelease
I am pretty new to react-native development, I have a project which run properly with iOS simulator, while on android (Emulator and device) it gives Unexpected token '>' error
Try to change "android" folder name to "android-backup"
And run following in the terminal:
$cd MyProjectFolder
$npm start
$react-native start
this work refresh your android project.
also you can clean gradlew with:
$cd android
$gradlew clean
try this
Open Terminal
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
react-native run-android
I perform offline bundling of my react-native project using CMD
react-native bundle --platform android --dev false --entry-file index.android.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res/
As bundinling is done offline i dont want JS server to start each time after running the command react-native run-android.
Is there any way out to avoid starting JS server
Internally, react-native run-android starts the packager and run installDebug task on gradlew.
To just run installDebug, on your project root directory run:
cd android && ./gradlew installDebug
