It can be possible to generate an unsigned apk version for testing purpose so you can run on your mobile.

Initially i got the red screen errors as most mentioned here. but i followed the same which was mentioned here and it worked for me.

On your console from working directory, run these four commands

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

gradlew assembleRelease

And then APK file will produce on : android\app\build\outputs\apk\debug\app-debug.apk

With me  in the project directory run the following commands   For react native old version  you will see index android js in root    mkdir -p android app src main assets  amp  amp  rm -rf android app build  amp  amp  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  amp  amp  cd android  amp  amp    gradlew clean assembleRelease  amp  amp  cd       For react native new version  you just see index js in root    mkdir -p android app src main assets  amp  amp  rm -rf android app build  amp  amp  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  amp  amp  cd android  amp  amp    gradlew clean assembleRelease  amp  amp  cd       The apk file will be generated at    Gradle  lt  3 0  android app build outputs apk  Gradle 3 0   android app build outputs apk release

There are two extensions you can use for this  This is added to react-native for setting these   disableDevInDebug  true  Disables dev server in debug buildType bundleInDebug  true  Adds jsbundle to debug buildType   So  your final project ext react in android app build gradle should look like below project ext react         enableHermes  false      clean and rebuild if changing     devDisabledInDev  true     Disable dev server in dev release     bundleInDev  true     add bundle to dev apk

Please follow those steps   Bundle your js   if you have index android js in project root then run   react-native bundle --dev false --platform android --entry-file index android js --bundle-output   android app build intermediates assets debug index android bundle --assets-dest   android app build intermediates res merged debug   if you have index js in project root then 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   Create debug apk   cd android    gradlew assembleDebug   Then You can find your apk here   cd app build outputs apk

Generate debug APK without dev-server If you really want to generate a debug APK  for testing purpose  that can run without the development server  Congrats  here I am to help you     Everyone is saying that we need to run two commands react-native bundle     and then gradlew assembleDebug but the generated APK still doesnot work without development server  After many research  amp  try I figured out that we need to change in the gradle file  as in step-2   Just follow these steps   In your react native project go to  android app src main create a folder assets edit android  gt  app  gt  build gradle  project ext react                 bundleInDebug  true     add this line     run this command at the root directory of your react native 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   Now  go into the android folder  cd android And  run this command  gradlew assembleDebug  if build failed  try building assembleDebug from android studio   This will create app-debug apk file in android app build outputs apk debug directory  which you can install  amp  run without dev-server

You need to manually create the bundle for a debug build   Bundle debug build    React-Native 0 59 react-native bundle --dev false --platform android --entry-file index js --bundle-output   android app src main assets index android bundle --assets-dest   android app src main res   React-Native 0 49 0  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   React-Native 0-0 49 0 react-native bundle --dev false --platform android --entry-file index android js --bundle-output   android app build intermediates assets debug index android bundle --assets-dest   android app build intermediates res merged debug   Then to build the APK s after bundling     cd android  Create debug build      gradlew assembleDebug  Create release build      gradlew assembleRelease  Generated  apk  will be located at  android app build outputs apk    P S  Another approach might be to modify gradle scripts

React Version 0 62 1 In your root project directory Make sure you have already directory android app src main assets   if not create directory  after that create new file and save as index android bundle and put your file in like this android app src main assets index android bundle After that run this 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  amp  amp    gradlew assembleDebug  Then you can get apk in app build outputs apk debug app-debug apk

As of react-native 0 57  none of the previously provided answers will work anymore  as the directories in which gradle expects to find the bundle and the assets have changed    Simple way without react-native bundle  The simplest way to build a debug build is without using the react-native bundle command at all  but by simply modifying your app build gradle file   Inside the project ext react map in the app build gradle file  add the bundleInDebug  true entry  If you want it to not be a --dev build  no warnings and minified bundle  then you should also add the devDisabledInDebug  true entry to the same map   With react-native bundle  If for some reason you need to or want to use the react-native bundle command to create the bundle and then the   gradlew assembleDebug to create the APK with the bundle and the assets you have to make sure to put the bundle and the assets in the correct paths  where gradle can find them    As of react-native 0 57 those paths are android app build generated assets react debug index android js for the bundle  and android app build generated res react debug for the assets  So the full commands for manually bundling and building the APK with the bundle and assets are   react-native bundle --dev false --platform android --entry-file index js --bundle-output   android app build generated assets react debug index android bundle --assets-dest   android app build res react debug  and then    gradlew assembleDebug  Bundle and assets path  Note that that paths where gradle looks for the bundle and the assets might be subject to change  To find out where those paths are  look at the react gradle file in your node modules react-native directory  The lines starting with def jsBundleDir   and def resourcesDir   specify the directories where gradle looks for the bundle and the assets respectively

I m on react native 0 55 4  basically i had to bundle manually   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   Then connect your device via usb  enable usb debugging  Verify the connected device with adb devices   Lastly run react-native run-android which will install the debug apk on your phone and you can run it fine with the dev server  Note    From 0 49 0  the entrypoint is a single index js gradlew assembleRelease only generates the release-unsigned apks which cannot be installed
