(INFO | Storing crashdata in: C:\Users\<>\AppData Problems running react-native android, caused by the emulator. (Windows)

[PedroEliasCS]

Description

With the update with the emulator, it is returning undue information, causing an error when giving the command to activate it.

1. Install latest version of Android Studio.
2. Create any Android emulator.
3. Run the command npx @react-native-community/cli@latest init AwesomeProject in your cmd
4. cd AwesomeProject
5. yarn or npm install (Confirm correct installation.)
6. yarn start
   I get the error:
   Failed to launch emulator. Reason: INFO | Storing crashdata in: C:\Users\<>\AppData\Local\Temp\\AndroidEmulator\emu-crash-34.2.15.db, detection is enabled for process: 15122

The reason for receiving it is an error in the latest version of the emulator that is caught by the react function:

const emulatorCommand =
  process.env.ANDROID_HOME != null
    ? `${process.env.ANDROID_HOME}/emulator/emulator`
    : 'emulator';

const getEmulators = () => {
  const emulatorsOutput = exec(`${emulatorCommand} -list-avds`).stdout;
  return emulatorsOutput.split(os.EOL).filter(name => name !== '');
};

Could anyone help me with this?

Steps to reproduce

1. Install latest version of Android Studio.
2. Create any Android emulator.
3. Run the command npx @react-native-community/cli@latest init AwesomeProject in your cmd
4. cd AwesomeProject
5. yarn or npm install (Confirm correct installation.)
6. npx react-native doctor
7. At this point it will say that there is no ADB configured.
8. By pressing F, we will see the problem there is a ghost emulator configured.

This is the script we use for release testing and is not the code is executed when you run yarn android. That code lives inside

https://github.com/react-native-community/cli

So please open this issue against:
https://github.com/react-native-community/cli/issues

Also in this last error screenshot, you can see that the error it says is "No connected devices". So it means your system is not configured properly for Android development.

Are you able to see your device if your adb devices in a console?

I'm closing as this is not a bug in React Native. You can get better support on https://github.com/react-native-community/cli/issues or StackOverflow
