Android studio 尝试调用虚拟方法'；com.google.android.gms.location.LocationRequest

公共视图onCreateView（@NonNull layoutiner充气机， 视图组容器，捆绑包savedInstanceState）{ homeViewModel= 新建ViewModelProvider（this.get）（HomeViewModel.class）； 视图根=充气机。充气（R.layout.fragment\u home，container，false）； //这里 init（）； mapFragment=（SupportMapFragment）getChildFragmentManager（）.findFragmentById（R.id.map）； getMapAsync（这个）； 返回根； }

您好，欢迎来到SO:），请在问题主体中添加一点解释

private void init() {
    locationCallback = new LocationCallback();
    locationRequest.setSmallestDisplacement(10f);
    locationRequest.setInterval(5000);
    locationRequest.setFastestInterval(3000);
    locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);

    locationCallback = new LocationCallback() {
        @Override
        public void onLocationResult(LocationResult locationResult) {
            super.onLocationResult(locationResult);
            LatLng newposition = new LatLng(locationResult.getLastLocation().getLatitude(),
                    locationResult.getLastLocation().getLatitude());
            mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(newposition, 18f));
        }
