Unable to load script from assets index.android.bundle on windows

Question

I\'m trying to run my first React Native project for first time on my device (Android 4.2.2).

And I get:

unable to load script from assets in

Answer 1

For this problem I just solve it by running:

react-native start

then

adb reverse tcp:8081 tcp:8081

on command line. And then i can run:

react-native run-android

So i will not waste my time to 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

every time.
