After I upgraded to Android Studio 3.0 Canary 1, the logcat tab in the Android Studio don't work properly. It continuously output the following error log. I don't know what's wrong.
05-19 18:05:18.676 10029-10072/com.example.chansoncc.bodypractice E/GRPC: tcp_client_posix.c:176] failed to connect to 'ipv4:127.0.0.1:12389': socket error: connection refused
Can anyone help?
