react-native run-android do not updating modified code.

[Anuj-786]

hey guys ! i have a problem with building the app when i run my app with react-native run-android it build successfully and install the app on emulator but does nor reflect the changes, it shows me the output of of default welcome page which comes on first run when we created the app.

[st0ffern]

have you tried react-native start --reset-cache ?

[Anuj-786]

@stoffern I tried this but my issues is not with this it works me fine. i want to create final apk by react-native run-android and want to install on another physical device not on emulator.

[st0ffern]

@Anuj-786 i dont quite understand what you are saying. If you want to generate a signed APK then follow this: https://facebook.github.io/react-native/docs/signed-apk-android.html if you want to deploy it to device and debug it on the computer follow this: https://facebook.github.io/react-native/docs/running-on-device-android.html

[Anuj-786]

thanks, @stoffern the problem was not properly finished but now i am able to run my app that you mentioned the link for adb devices. It works me fine thank you man.

I am having the same issue. The react-native is unable to detect any change for ios as well as android. I am using iginte boilerplate. Cleaned the project multiple times, deleted cache, re-built things, but looks like JS code is even compiled. Because when I took out whole JS code directory, the build still succeeded.

I am having the same issue. How can I solve this issue?? Only pre version is build in real device. On virtual device(Genymotion), this problem is not ocurred.

[mistypix]

everytime i make some change to app.js file, i have to rebuild the project again with npm start. why are the changes not appearing automatically when i save ? or is this the way it is supposed to be?

[vanskins]

I'm also facing this issue :( is there any fix for this ?

[hongsa]

On temporary, I use ./gradlew assembleRelease, move to real device to apk file.

[PetersonLian]

Any solutions?

[mistypix]

What i found was that you have to go to recent apps list in your android phone, and clear the Expo app from the list, and open the app again, then it will show the changes made in app.js file... i hope it helps

[klaszlo8207]

When I am run the app in the emulator the images updating. But when I run my app on a real device I get the old images on that. I just changed an image logo in the assets folder. Wtf happening?

[st0ffern]

Are the images located inside the project folder? Try restarting the watchdog

[raphcadiz]

Hi guys, any fix for this? After we deployed our app for production we got this problem. The changes I made is not longer reflecting on the application. I run command react-native run-android to test the android version

[debajyoti-thetaonelab]

Hi! Reloading(shake/dev menu and reload option) from android device isn't loading my new changes! But If I restart RN packager with --reset-cache and reloads from android, it works. Turning on hotreload doesn't works either! After saving code in VSCode rn hotreloads but it doesn't changes. (the changes includes style changes etc, no local resource require) I have tried to clear watchman cache watchman watch-del-all ; watchman shutdown-server

[Ilario17]

Any news? I also have this issue.

[Dhrupal]

Please help

[DrWongKC]

I have the same problem as well.

I have sort of the same issue today, the app on android suddenly keep an old version of the code and doesn't reflect any changes in the current code. Maybe it's affected by a lot of cache clean kinds of stuff I did yesterday.

1.I was looking around and found this bundle issue, it works for me https://stackoverflow.com/questions/44446523/unable-to-load-script-from-assets-index-android-bundle-on-windows/44476757#44476757

2. But after that, I got another issue with Development menu (Not able to open it) Here is the solution I found for that Open MainApplication.java in the android/app/src/main/java/{packagename} directory ,delete the following code if exist

import com.facebook.react.BuildConfig;

BuildConfig.DEBUG should be true in debug mode, while in com.facebook.react.BuildConfig it is always false.

Hope this is useful :)

[zengkm]

@poepanda It works for me .Thank you!

[klaszlo8207]

I just restarted the pc and worked again like a charm. It is sometimes frustrating.

[BipinAle]

This worked for me. I had same issue but solved exporting path

1. echo 'export ANDROID_HOME=/Users/$USER/Library/Android/sdk' >> ~/.bash_profile
2. echo 'export PATH=${PATH}:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools' >>~/.bash_profile then
3. source ~/.bash_profile

[jasmineelamblakatt]

Below code worked for me...

1. Perform adb reverse..check below got to platform-tools in cmd C:\SetUps\AndroidSetUp\sdk\platform-tools> adb reverse tcp:8081 tcp:8081
2. Then delete any bundle file if present in 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
3. react-native run-android

[Zedonboy]

@jasmineelamblakatt it only works for the time being. If i change any code in App.js, you dont expect a developer to go through those steps, in other to update the index.android.bundle file.

i have same issue, but i want it to automatically update index.android.bundle file

[fuyue111]

dev setting set the ip to 127.0.0.1:8081 worked for me.

[luizguilhermefr]

This bug is happening to me when using physical device on same wi-fi network.

This doesn't happen to me when using emulator on same host PC.

[deva11]

Follow the procedure first time.

mkdir android/app/src/main/assets

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

Execute the Following code every time when you run your code in physical device.

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

[totoro0103]

Thank @deva11 . It's work for me

[mistypix]

Moving to flutter.

_# ###SOLUTION

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

OUTPUT will be : c:\Users\lenger\Desktop\webrowser>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 Scanning folders for symlinks in c:\Users\lenger\Desktop\webrowser\node_modules (43ms) Scanning folders for symlinks in c:\Users\lenger\Desktop\webrowser\node_modules (38ms) Loading dependency graph, done. bundle: start bundle: finish bundle: Writing bundle output to: android/app/src/main/assets/index.android.bundle bundle: Done writing bundle output

and after

Run react-native run-android again, you will find your modification work.

I'm seeing this issue when running two physical Android devices via USB, 90% of the time if I switch branch in git, then run react-native run-android both devices will install the new apk successfully but only 1 device will have the updated js bundle :expressionless: Even uninstalling the APK from both devices and running watchman watch-del-all immediately after changing branch has no effect. Usually running react-native run-android once or twice more works. As you might imagine this is making code review painful because I have to guess if I'm actually running the latest changes or not...

[Etregoning]

I'm having this same issue. None of the solutions mentioned here or anywhere else have worked for me.
