i think 1 related ..

public class myarrayadapter extends arrayadapter<string> {      private final activity context;     private final string[] alisttext;     private final string [] meaningtext;      public myarrayadapter(activity context, string[] wordtext, string[] meaningtext) {         super(context, r.layout.desclist2, wordtext);         this.context=context;         this.alisttext= wordtext;         this.meaningtext=meaningtext;     } } // .....   @override public void onrestart(){     super.onrestart();     clickflag = false;     clickwordflag = false;     myarrayadapter.notifydatasetchanged();  <-- line 685 } handler handler = new handler(){  <-- line 709     @override     public void handlemessage(message msg){         progressdialog.dismiss();          if{ ....         }else{             myarrayadapter = new myarrayadapter(worddescription.this, wordarray, meaningarray);             listview.setadapter(myarrayadapter);         }      }

change

myarrayadapter.notifydatasetchanged();

to

if(myarrayadapter != null)       myarrayadapter.notifydatasetchanged();

i suggest vipul shah told in comment.
