This is not giving me the package bundle js what to do. and It's been a couple of days i stock in this problem i could not get help.

Below is the screencast of my code:

Thanks in Advance!

Your screenshot starting the server for react native debug.

The app in the debug mode will point to this server js then you can change your code for debug easily.

If you want to package the bundle file you can use these commands:


react-native bundle --platform android --dev false --entry-file --bundle-output android/app/src/main/assets/ --assets-dest android/app/src/main/res/


react-native bundle --platform ios --dev false --assets-dest ./ios --entry-file index.ios.js --bundle-output ios/main.jsbundle

Got Solution For me:

Go to your project directory and check if this folder exists android/app/src/main/assets

i) If it exists then delete two files viz and

ii) If the folder assets doesn’t exist then create the assets directory there.

  1. From your root project directory do

    cd android

    ./gradlew clean

  2. Finally, navigate back to the root directory and check

i) If there is only one file i.e. index.js then run following command

react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/ --assets-dest android/app/src/main/res

NOTE: That is one single command.

ii) If there are two files i.e and index.ios.js then run this:

react-native bundle --platform android --dev false --entry-file --bundle-output android/app/src/main/assets/ --assets-dest android/app/src/main/res

This is a single command too!

  1. Now run react-native run-android

I have just found why my react-native application is not building bundle js because of watchman and after uninstall previous watchman and installing new watchman.It working correctly thanks.
Using Following Code.

$ git clone
$ cd watchman/
$ git checkout v4.7.0
$ sudo apt-get install -y autoconf automake build-essential python-dev
$ ./ 
$ ./configure 
$ make
$ sudo make install

$ watchman --version
$ echo 999999 | sudo tee -a /proc/sys/fs/inotify/max_user_watches  && echo 999999 | sudo tee -a  /proc/sys/fs/inotify/max_queued_events && echo 999999 | sudo tee  -a /proc/sys/fs/inotify/max_user_instances && watchman  shutdown-server
