android - JSONObject cannot be cast to com.parse.ParseGeoPoint -


i saving geopoint in jsonobject using:

        jsonobject obj=new jsonobject();         jsonarray ja=new jsonarray();          if(lx.size()==0){             toast.maketext(ctx, "no location upload now", toast.length_long).show();         }         else{             for(int uq=0;uq<lx.size();uq++){                 double latit=lx.get(uq).getlatit();                 double longit=lx.get(uq).getlongit();                 parsegeopoint pgpoint=new parsegeopoint(latit,longit);                 ja.put(pgpoint);               }             try {                 obj.put("locations",ja);             } catch (jsonexception e1) {                 // todo auto-generated catch block                 e1.printstacktrace();             }

after sending jsonobject parse cloud.

                po.put("historyfile", obj);                 po.saveinbackground(new savecallback() {

now tried this: 

            jsonarray locations;             parsegeopoint             locations = obj.getjsonarray("locations");             (int yx = 0; yx < locations.length(); yx++) {                 pg =(parsegeopoint)locations.get(yx);                 //draw geopoint on googlemap             }

firstly @ line:

             pg =(parsegeopoint)locations.get(yx);

i got error of type mismatch.when typecasted parse object ran fine;but when tried run apk got error:

            caused by: java.lang.classcastexception: org.json.jsonobject cannot cast com.parse.parsegeopoint

try go parse.com data page , copy paste jsonobject jsonlint.com, see pg looks once saved inside jsonobject. string value can treated jsonobject, there no way string, or jsonobject matter can cast directly parsegeopoint. @ best can dive in retrieve lat/lon values:

jsonarray locations; parsegeopoint locations = obj.getjsonarray("locations"); (int yx = 0; yx < locations.length(); yx++) {     pg = locations.getjsonobject(yx);     double lat = pg.getdouble("latitude")     double lon = pg.getdouble("longitude")     //draw geopoint on googlemap }

now havent tried save parsegeopoint jsonobject way do, not sure if above correct, example.

if need able store , retrieve location, do:

... for(int uq=0;uq<lx.size();uq++){     double latit=lx.get(uq).getlatit();     double longit=lx.get(uq).getlongit();     jsonobject jsonpos = new jsonobject()     json.put("lat", latit);     json.put("lon", longit);     ja.put(jsonpos); } ...

and 

jsonarray locations; parsegeopoint locations = obj.getjsonarray("locations"); (int yx = 0; yx < locations.length(); yx++) {     pg =locations.getjsonobject(yx);     double lat = pg.getdouble("lat")     double lon = pg.getdouble("lon")     //draw geopoint on googlemap }
