java - Parse "no results found for query (code 101)". Can't get object id -

i've installed example parse server (https://github.com/parseplatform/parse-server-example) on desktop , made simple app test it.

my app saves object server, gets object , sets mtextview's value value of object.

the problem is, when try code data server works:

    query.getinbackground("5k7n8a8dmd", new getcallback<parseobject>() ... 

(got object id curl)

but when try (to object id w/o using curl):

            gamescore.saveinbackground(new savecallback() {             public void done(parseexception e) {                 if (e == null) {                     objectid = gamescore.getobjectid();                 } else {                     log.e("saveinbackground", geterrormessage(e));                 }             }         });  ...      query.getinbackground(objectid, new getcallback<parseobject>() ... 

it doesn't work.

logcat:

e/getinbackground﹕ no results found query - code: 101

constants.java

    public class constants {     public static string server_url = "http://192.168.1.14:1337/parse/";     public static string app_id = "myappid"; } 

thanks in advance.

try this

parsequery<parseobject> query = parsequery.getquery("_foo1234"); query.whereequalto("objectid","wfbb0gpckp"); query.findinbackground(new findcallback<parseobject>() {     public void done(list<parseobject> objects, parseexception e) {         if (e == null) {             // row of object id "wfbb0gpckp"         } else {             // error         }     } }); 

also change

parsequery<parseobject> query = parsequery.getquery("foo1234"); 

to

parsequery<parseobject> query = parsequery.getquery("_foo1234");  

see if works.
