Solution 1:

In your scenario before running react native application you need to create emulator using Android Studio. You can view official documentation about running application on device by here

Before running your project make sure you have installed adb drivers - More

First of all create AVD using Android Studio.

Open your project android folder using Android Studio.

1. Click AVD Manager from Android Studio2. Click Create Virtual Device3. Select your device from device list and click Next4. Select the android os version from the available version list and click Next5. On last keep default settings on device and click Finish

After that you can see your available android emulator device list from AVD Manager window.

* Before run your react native application make sure you have turn on and run the android emulator from android studio

After that run your project using react-native run-android

Solution 2:

You can run the command adb devices to check if there is any device attached. It should list atleast one device for it to work
