android - Realm doesn't write the data in IntentService -

i have realm database in app. when app active have no problem writing data if start intentservice , close app, have nothing in realm database.

my intentservice:

@override protected void onhandleintent(intent intent) {              realmresults<hashtagobject> hashtags;             subscriberobject subscriber = new subscriberobject();              realm realmforthisthread = realm.getdefaultinstance();             hashtags = realmforthisthread.where(hashtagobject.class).findall();             for(int i=0;i<hashtags.size();i++){                 getrecentlytag(constants.api_url);             }             realmforthisthread.begintransaction();              (map.entry entry : hm.entryset()) {                 if(realmforthisthread.where(subscriberobject.class)                         .equalto(subscriberobject.id,entry.getkey().tostring()).findall().isempty()) {                     subscriber.setid(entry.getkey().tostring());                     subscriber.setusername(entry.getvalue().tostring());                     subscriber.setdate(mdate.gettime());                     realmforthisthread.insert(subscriber);                 }             }             realmforthisthread.committransaction();             realmforthisthread.close(); } 

private void getrecentlytag(string path,final string tagname){

            httpurlconnection urlconnection = null;             try {                 thread.sleep(10000);                 url url = new url(path);                 urlconnection = (httpurlconnection) url                         .openconnection();                 urlconnection.setrequestmethod("get");                 urlconnection.setdoinput(true);                 urlconnection.connect();                 string response = tools.streamtostring(urlconnection                         .getinputstream());                 jsonobject jsonobj = (jsonobject) new jsontokener(response)                         .nextvalue();                 for(int i=0;i<jsonobj.getjsonarray("data").length();i++) {                     jsonobject json = (jsonobject) jsonobj.getjsonarray("data").get(i);                    hm.put(json.getjsonobject("user").getstring("id"),json.getjsonobject("user").getstring("username"));                 }              }catch(exception exc){                 exc.printstacktrace();             }finally {                 if(urlconnection!=null){                     try{                         urlconnection.disconnect();                     }catch(exception e){                         e.printstacktrace();                     }                 }             } } 

i using:

classpath "io.realm:realm-gradle-plugin:2.0.2" // top-level build file compile 'io.realm:android-adapters:1.3.0' //app gradle  

starts intentservice in fragment like:

    @onclick(r.id.find_users)     public void startclick(){         intent intent = new intent(getactivity(), subscribersgathering.class);         getactivity().startservice(intent);     } 

realm cofigs in application class:

    realm.init(this);     realmconfiguration realmconfiguration = new realmconfiguration.builder()             .deleterealmifmigrationneeded()             .build();     realm.setdefaultconfiguration(realmconfiguration);
