Unable to run react native app after installing react native, chocolateyf

I’ve been to Slack and they could not help. There were issues with Java compiler. I found some youtube and react native solutions and now the error has changed to “com.android.builder.testing.api.DeviceException: No connected devices!”. Please see the full long results here:

That’s not really a Gradle question, other than you use Gradle to execute the build.
Your Android tools cannot find your device, or you did not have connected one.
I recommend you ask in some Android community instead where the Android development experts are hanging around and can answer non-Gradle questions. :slight_smile:
