activity class calling this

import android.content.context; import android.content.intent; import android.os.bundle; import android.support.design.widget.floatingactionbutton; import android.support.v4.app.fragment; import android.view.layoutinflater; import android.view.view; import android.view.viewgroup; import android.widget.textview;   /**  * simple {@link fragment} subclass.  */ public class accountsettingfragment extends fragment {     floatingactionbutton fabedit;     databaseadaptor databaseadaptor=null;     textview patientid;     private context context;       public accountsettingfragment() {         // required empty public constructor     }       @override     public view oncreateview(layoutinflater inflater, viewgroup container,                              bundle savedinstancestate) {         // inflate layout fragment         view view=inflater.inflate(r.layout.fragment_account_setting, container, false);          fabedit=(floatingactionbutton)view.findviewbyid(r.id.btnfabedit);         patientid=(textview)view.findviewbyid(r.id.patientid);         context=getactivity();         databaseadaptor=new databaseadaptor(context);        databaseadaptor.pullaccsett();         fabedit.setonclicklistener(new view.onclicklistener() {             @override             public void onclick(view v) {                 intent intent = new intent(getactivity(), accountssettingedit.class);                 getactivity().startactivity(intent);             }         });           return view;     }   } 

message class

import android.content.context; import android.widget.toast;  /**  * created frnds on 3/2/2016.  */ public class message {     public static void message(context context,string message){         toast.maketext(context,message,toast.length_long).show();     } } 

and when call pullaccsett(); app hangs , goes not responding. , log cat shows message: package has posted 50 toasts. not showing more. reason behind this.

your while loop thinks runs infinite time. because every time true , have no break statement. change code this.

try {     if (acccursor.movetofirst()) {         while (acccursor.movetonext()) {         //code fetch data cursor         }     }      acccursor.close(); }catch (exception e) {     log.e("getdata", e.getmessage(), e); }
