Unable to make my app location aware

Question

I am following the android tutorial on making your app location aware here
but when I run it in the emulator the below method

@Override
public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {
    Log.i("state", "Connection failed: ConnectionResult.getErrorCode() = " + connectionResult.getErrorCode());
}

shows in the Logcat:

Connection failed: ConnectionResult.getErrorCode() = 9

Does anyone know what ErrorCode 9 means?

Answer 1

public static final int SERVICE_INVALID

The version of the Google Play services installed on this device is not authentic.

Constant Value: 9

Source: ConnectionResult

Are you running the emulator that uses the Google APIs?
