react-native-geolocation-service无法正常工作

Question

我的componentDidMount函数如下所示：

async componentDidMount() {

    const hasLocationPermission = await PermissionsAndroid.check( PermissionsAndroid.PERMISSIONS.ACCESS_FINE_LOCATION )
    console.log('hasLocationPermission ====> ', hasLocationPermission) //returns true
    if (hasLocationPermission) { 
        Geolocation.getCurrentPosition(
            console.log('1 ======> ')
            (position) => {
                console.log('2 ====================================================>')
                console.log(position);

            },
            (error) => {
                // See error code charts below.
                console.log('3 ====> ')
                console.log(error.code, error.message);
            },
            { enableHighAccuracy: true, timeout: 15000, maximumAge: 10000 }
        );
    }
    else
    {
        console.log('Does not have permission to access location')
    }

    }   

除了hasLocationPermission为true之外，没有任何控制台日志语句可以在其中打印。我觉得Geolocation.getCurrentPosition始终为null。我是React Native的新手，我在做错什么吗？请帮我在这里。谢谢！
