when I run my project I cannot see the bundler running, it just loads and builds successfully but then disconnects. what is the problem?
I recommend these steps:
make sure you have a compatible version of SDK build-tools, try to keep only one. (Also, SDK 11 might be better than SDK 14), Gradle version might have to be downgraded to 6.3, and start with Marshmellow (API 23), (that is what React Native page recommends).
Try this option if you cannot connect to the development server:
create assets folder if you cannot find it in:
cd android/app/src/main/assets
then cd to project folder and 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
some people say that react-native-cli might cause some issues, so try uninstalling it.

I'm trying to implement the video conference functionality by using the react-native-jitsi-meet library. But app is being crashed without showing any issue.
I have used added the package and implemented the android process for the react version > 0.60 as mentioned in the document(https://github.com/skrafft/react-native-jitsi-meet) unable to find the issue. Haven't added any code in the JS file too.
I have tried react-native-jitsi-meet module not found also but still the issue continues.
As it is specified in documentation we already changed the app.bundle as rename and it is bundling incorrectly so do this changes.
Remove the following file
android/app/src/main/assets/index.android.bundle
npx react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/app.bundle --assets-dest android/app/src/main/res/ && cd android && ./gradlew assembleDebug
I built a new APK after I added react-redux and persist. The debug build is working perfect but the release one seems it didn't get the new code cause its working like before.
I'm not sure, why it's happening?. I tried ./gradlew clean too but it didn't help.
Delete the build folder from the android/app directory. Delete Node Modules and do a fresh install. If this does not work then run metro bundler using the below command.
react-native start --reset-cache
The solution was to run 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/ and then building the apk again
I created the app by working on the following tasks for the launch of the Android app.
react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle
After that, I tried to build the app again in development mode (react-native run-android), but the app continues to be built in release mode. How do you build it development mode like before?
react-native run-android
When I do this react-native run-android, Metro Bundle does not run and just build the release app on my device.
I want the Metro Bundle to be turned on and built in development mode when I execute this.
I had the same problem, it was fixed by deleting the line:
import com.facebook.react.BuildConfig;
from the MainApplication.java
Below can clear your thoughts about the metro server and development mode
When you are in development mode and need to debug the application
live by changing the content of the code the you should always do:
react-native run-android, it will always run the metro server and
you have the feature to live reload the application whenever the code
changes. Note: This will work for both the emulator and phones
connected to your pc through cables or by server.
Now, in case you want to build an apk and wanted to test on a real
device which enables you to discard the consoles and for the further
testing the application before making it live then you should always
run the below command
Bundle first all the files, by going inside your project
structure
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, create a bundle apk by going inside the android folder and run the below command./gradlew assembleDebug
Note : it will create the apk in you build folder inside this
directory project_name\android\app\build\outputs\apk\debug
I hope this helps....Thanks :)
I created AwesomeProject and run react-native run-android in root directly of my project, message in android simulator is as follows:
Unable to load script.Make sure you are either running a Metro server or that your bundle 'index.android.bundle' is packaged correctly for release.
To fix this err i try to run :
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/
but it didn't work.message in android simulator
You have to start the bundler first, run
npm start
or
react-native start
in the root of your project.
I made some styling changes to my react native app. Everything looks good in debug so I tried to run the release variant using 'react-native run-android --variant=release' and none of that changes in debug show up. I made sure I wasn't crazy and removed the background image. The release variant didn't change at all. I then tried generating the signed apk and installing it manually. Same thing.
I can't seem to find anything on google. Has anyone had this problem before or have suggestions on what to try? I've combed through all the config files and everything seems right. I know its hard without being able to look at the code but I can't share it since its for internal company use only.
For anyone still struggling with this, updating index.android.bundle usually solves this issue:
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/
1 - Perform adb reverse..check below got to platform-tools in cmd
C:\Users\username\AppData\Local\Android\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 - run --> react-native run-android --variant=release
or react-native run-android
