Answer 1

After trying @SmoggeR_js answer and still if you have the same problem try following (Assuming that you have created keys and already signed the apk)

1. Delete build inside android/app folder
2. Delete build inside android folder
3. run rm -rf $HOME/.gradle/caches/ to delete cache
4. Open build.gradle --> android/app/build.gradle
5. comment out this line apply from: "../../node_modules/react-native/react.gradle"
6. Delete index.android.bundle file from assets folder ( android/app/src/main/assets/index.android.bundle)
7. run following command 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
8. react-native run-android --variant=release (you have to generate signed keys and all the keys should updated in the gradle file ref (https://s-pace.github.io/react-native/docs/signed-apk-android.html)

In my case, deleting below line in gradle.properties solved it.

org.gradle.configureondemand = true

Assuming that you are in the right folder, try to do 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/

if you have index.android.js, do this instead:

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/

Then just execute react-native run-android.

Answer 4

In your project directory, there is package.json file. You can add following code snippet in that json file under scripts:. After that you can run application using one command that is npm run android-windows. To work fine you should add below code script.

"android-windows": "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"

Answer 5

Fix it in 3 steps:

1. Enable Live Reload
2. Disable Hot Reloading
3. In Dev Settings, uncheck JS Dev Mode

Now your app automatically updating everytime you made changes to your codes.

Answer 6

Silly mistake by me that not to save edits of App.js. After Saving data will reflect :)
