Make sure you have an Android emulator running or a device connected and have
set up your Android development environment:
https://facebook.github.io/react-native/docs/getting-started.html
error Command failed: gradlew.bat app:installDebug. Run CLI with --verbose flag for more details.
First of all you should update your node.js
Then run the installation's cammands and for Iranian it's better to use shecan.ir before running build run-android command instead of unworking vpn.
I did these steps and the problem solved.

I have a problem with building react native app on android emulator. I tried to crate app with Expo and everything works great on android device, android emulator(Android studio) and web. But when I try to create with React Native CLI a have a build error.

What can be wrong? Thanks a lot.

since the port is mentioned it looks a little bit like you are not connected and need to reconnect your adb server to the application on metro. To do so you need to install adb tools (I believe it was via brew, but google will help) and then run(in 2nd Terminal beside metro):
adb reverse tcp:8081 tcp:8081
When it shows 8081 in the new terminal, you can try again.
I use macbook m1 and set sdk in android studio.
I follow all the process: https://reactnative.dev/docs/environment-setup.
But I couldn't understand above process.
when I run this command line from terminal. It says
zsh: command not found: sdkmanager
So I pass that process.
Except for that, I installed all as doc says.
But when I run npx react-native run-android.
Error message below appears.
what is the problem?

You should connect a physical device or launch simulator from android studio, before running
react-native run-android
> com.android.builder.testing.api.DeviceException: No connected devices!
You should check if you enable the debug mode in your phone.
And follow this.
export PATH=~/Library/Android/sdk/tools:$PATH
export PATH=~/Library/Android/sdk/platform-tools:$PATH
adb reverse tcp:8081 tcp:8081
adb shell input keyevent 82
The first one enables adb in your terminal.
And the second onen enables 8081 port.
If you run the third one then you could see the developer menu in your app.
I tried changing option from 'charging this device' to 'transfer files' and now it's working fine. Thank you everyone!
I've got this issue. Here's my solution: the path to platform-tools in the environment variable must be in PATH and not in ANDROID_HOME!

react-native run-android is basically running ./gradlew installDebug. And the error says it all. There is no connected devices so it is not able to install the app.
There are not connected Android devices or emulators running.
If you are using an Android Emulator, make sure that your emulator is up and running. If you are running on a real device, make sure that the Developer Mode is enabled on your device and USB Debugging is enabled.
Run adb devices to see the list of currently connected Android instances.
Thank you very much for answering the question very soon.
