parse-platform - 无法在解析中应用地理查询（解析框架）

Question

我试图在解析中应用地理点，但我无法进行查询。代码如下。

ParseObject placeObject = new ParseObject("placeObject");
ParseGeoPoint userLocation = (ParseGeoPoint) placeObject.get("location");

ParseQuery query = new ParseQuery("PlaceObject");
query.whereNear("location", userLocation);
query.setLimit(10);
query.findInBackground(new FindCallback() {
    public void done(List<ParseObject> Locaciones, ParseException e) {

        if (e == null) {

            Log.d("ERROR",Locaciones.toString());
            // object will be your game score
        } else {
            Log.d("ERROR",e.toString());
            // something went wrong
        }

    }
});

尝试这个：

ParseObject.registerSubclass(MasterEntity.class);
    ParseGeoPoint userLocation = new ParseGeoPoint(latitude,longitude);
    ParseQuery<MasterEntity> query = ParseQuery.getQuery("UserMaster");
    query.whereNear("location", userLocation);
    query.setLimit(30); 
    query.findInBackground(new FindCallback<MasterEntity>() {

        @Override
        public void done(List<MasterEntity> mlist, ParseException e) {
            dlg.dismiss();
            if (e==null) {


            for (int i = 0; i < mlist.size(); i++) {
                MasterEntity cc =  mlist.get(i);

                String s_email = cc.getEmail();
                String s_uname = cc.getuserName();
                String s_objid = cc.getObjectID();
                List<ParseObject> aryFollower = cc.getFollowers();
                List<ParseObject> aryFollowing = cc.getFollowing();


            }

            }
            else
            {
                 Alert.alertOneBtn(getActivity(),"Something went wrong.Please try again later");
            }
        }
    });
