Expo app is not installing on Android emulator

Description

After creating a new project, I ran ‘yarn run android’ but instead of getting the expo app on the emulator I’m getting an error.

Expected Behavior

Expo app should be installed on my emulator and my app should be up and running.

Observed Behavior

I’m getting an error in the terminal while running the packager. Although I’m getting the QR code.

If there’s an error message, please paste the full terminal output and error message in this code block:

hello! try deleting the directory C:\Users\Rizwan\.expo\android-apk-cache and opening the project on android again

I had the same problem (on macOS), can confirm that deleting the .expo/android-apk-cache directory and re-running yarn start android fixed it for me
