I am installing React Native according to this website
https://reactnative.dev/docs/environment-setup
it's very useful until I run the command react-native run-android, this is the error I receive:
Failed to launch emulator. Reason: Emulator exited before boot..
warn Please launch an emulator manually or connect a device. Otherwise app may fail to launch.
after i launch an emulator manually project build successfully but application is installed but not open?
create new emulator
increase space of emulator
wipe data of emulator
cold boot emulator
uninstall application
clean gradle

I go to start emulator on my mac m1 and it'll bring up the phone emulator however my project is not uploaded to the phone.
I am getting this error in the terminal:
› Opening on Android...

The ios emulator seems to be working fine
I just solved this issue for myself, it appears your emulator doesn't have enough storage assigned to it.
Here's how you can increase the storage on your emulator
For my emulator I increased the device Internal Storage to 8GB and enabled No SDCard. This has allowed me to emulate my expo react-native app on Android while running on my M1 silicon chip MacBook.
I currently using react-native 0.65.
But crashes does not show on ms appcenter
I followed these instruction
https://learn.microsoft.com/en-us/appcenter/sdk/getting-started/react-native#3-add-the-app-center-sdk-modules
https://learn.microsoft.com/en-us/appcenter/sdk/crashes/react-native
I build an APK throwing an error
Then installed it on a device.
The app crashed but no item log registered on appcenter.
Any solutions for this?
Thank you
When I run "npm start" and then 'a'/ "sudo expo start --android" the connection to the android emulator fails.
the error I get is:
Couldn't start project on Android: Error running adb: No Android connected device found, and no emulators could be started automatically.
Please connect a device or create an emulator (https://docs.expo.io/workflow/android-studio-emulator).
Then follow the instructions here to enable USB debugging:
https://developer.android.com/studio/run/device.html#developer-device-options. If you are using Genymotion go to Settings -> ADB, select "Use custom Android SDK tools", and point it at your Android SDK directory.
While trying to debug it I found:
The app is running on web browser
While launching the AVD on emulator on android-studio I get on android studio events:
Emulator: E0810 10:41:04.480101550 89662 socket_utils_common_posix.cc:201] check for SO_REUSEPORT: {"created":"#1597045264.480085451","description":"SO_REUSEPORT unavailable on compiling system","file":"/mnt/tmpfs/src/android/emu-master-dev/external/grpc/src/core/lib/iomgr/socket_utils_common_posix.cc","file_line":169}
I Made sure that .bashrc includes the right SDK path: "export ANDROID_SDK=/home/user/Android/Sdk", and followed this link
I'll mention that the emulator already ran my app, I'm not sure what changed the configuration and made the app not running on android-studio emulator. I re-install android-studio but it's still have no connction
I build up a simple app with react native and its nicely work in my emulator. Then i tried to run it in smartphone using USB debug option. I can see the app in my phone under apps list, but when i try to open it for further developments its shows this error. Any idea what i am missing for react-native run-android in a physical device? I am working in a windows PC
