android - why is BroadcastReceiver called twice from the OnPostExecute in asystask? -

the question simple created broadcaster class in fragrment class. , call asystask class perform. after execute class (on onpostexecute method), send broadcaster intent fragment class once.

however, result got onreiver method 2 times. (i verified using log got onpostexecute method , send broadcaster once, onreiver method triggered twice). can give me help. bugs me , wasted time. thank you

public class fragment extends fragment{   @override   public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) {        currentview = inflater.inflate(r.layout.left_panel, container, false);       mcontext = currentview.getcontext();       init();       return currentview;   }    @override   public void onresume(){       super.onresume();       localbroadcastmanager.getinstance(getactivity()).registerreceiver(albumlistbroadcaster, new intentfilter(commonutilities.broadcasterofalbumtitlelist));   }    private void init(){        albumlistbroadcaster = new albumlistbroadcaster();        setonclickbuttonsevent();       clearbtn();   }    public void setonclickbuttonsevent(){       //modifybtn.setonclicklistener(new modifyaccountbtnlistener());       modifybtn.setonclicklistener(new onclicklistener() {             @override             public void onclick(view v) {                  intent intent = new intent(mcontext, webactivity.class);                 startactivityforresult(intent, requestcode);             }         });   }      @override     public void onactivityresult(int requestcode, int resultcode, intent intentdata) {       // todo auto-generated method stub         if(requestcode == requestcode){             if(resultcode == result_ok){                 //sendbroadcaster();                 data = this.getactivity().getsharedpreferences(commonutilities.sharedpreferenceurl, 0);                 string userttoken = data.getstring("usertoken", "");                 string mobileuserid = data.getstring("mobileuserid", "");                 string services = intentdata.getstringextra("servicesjsonarray");                  try {                     jsonarray socialmedias = new jsonarray(services);                     log.d("socialmedias", socialmedias.tostring());                     clearbtn();                     //jsonarray accountinfo = new jsonarray(services);                     mdisplaypiconalbumfragment.ondisplaypiconalbumfragment(new jsonarray());                     if(socialmedias.length() > 0){                          totalarrayforalbum = new jsonarray();                         int lastnum = socialmedias.length();                          for(int = 0;i< lastnum;i++){                             jsonobject 1 = socialmedias.getjsonobject(i);                             string socialname = one.getstring("service_display_name");                             activatebtn(i,socialname);                             string servicename = one.getstring("service_name");                             map <string,string> map = new hashmap<string,string>();                             map.put("usertoken", userttoken);                             map.put("userid", mobileuserid);                             map.put("servicename", servicename);                             new requestalbums(map,getactivity()).execute(commonutilities.albumlisturl);                          }                     }else{                         arraylist<string> emptyarr = new arraylist<string>();                         emptyarr.add(getstring(r.string.emptylist));                         createmenu(emptyarr);                      }                 } catch (jsonexception e) {                     // todo auto-generated catch block                     e.printstacktrace();                 }              }         }      super.onactivityresult(requestcode, resultcode, intentdata); }   public class albumlistbroadcaster extends broadcastreceiver{      string title = "";      @override     public void onreceive(context context, intent intent) {         log.d("onrecive","i here");         }  }      public class requestalbums extends asynctask<object,object,string>{  private httpentity httpentity; private httpget httpget; private httpclient httpclient; private inputstream inputstream; private httpresponse httpresponse; private map<string,string> param; private context mcontext;  public requestalbums(map<string,string> param,context c){     this.param = param;     mcontext = c; }  @override protected void onpreexecute(){     // todo auto-generated method stub     super.onpreexecute(); }   @override  protected void onpostexecute(string result) {         // todo auto-gworkenerated method stub       log.d("background", result);       arraylist<string> resultarr = getonlytitle(result);       intent intent = new intent(commonutilities.broadcasterofalbumtitlelist);       intent.putstringarraylistextra("titlelist", resultarr);       intent.putextra("resultinfo", result);       //intent.putextra("titlelist", resultarr.tostring());        localbroadcastmanager.getinstance(mcontext).sendbroadcast(intent);       //super.onpostexecute(result); }  @override protected string doinbackground(object... input) {      --- }     }  

have noticed have sendbroadcast() function being called in onactivityresult?

@override public void onactivityresult(int requestcode, int resultcode, intent intentdata) {   // todo auto-generated method stub     if(requestcode == requestcode){         if(resultcode == result_ok){             sendbroadcaster();
