I have add the key in app.json but still this error occurs. "API key not found. Check that com.google.android.geo.API_KEY"
I have added the key and SHA-1 in google credentials but still error is not resolved. Please provide the solution.
Rebuild development build through expo with
eas build --profile development --platform android
or whatever build you use and try again.
The api key changes aren't updated when you hot reload the app, you need to rebuild it. I had the same issue and that's how I solved it. Your app.json seems fine.
