and handler code

 private handler handler = new handler() {     public void handlemessage(message msg) {         count += 1;         if(count<=3){             try{                 log.e("@@","inside handler try count="+count);                 if(myprogressdialog.isshowing())                     myprogressdialog.dismiss();             }catch(exception e){                 e.printstacktrace();             }             //new checkloginstatus().execute();             sendsms();             if(!myprogressdialog.isshowing()){                 myprogressdialog=new progressdialog(myclass.this);                 myprogressdialog.settitle("my message\nstep 2 of 4");                 myprogressdialog.setmessage("me message\n" +                         "please wait... attempt "+(count));                 myprogressdialog.setcancelable(false);                 myprogressdialog.show();             }         }else if(count == 4){             try{                 log.e("@@","inside handler else "+count);                 if(myprogressdialog.isshowing())                     myprogressdialog.dismiss();             }catch(exception e){                 e.printstacktrace();             }             count = 1;                final textview message = new textview(getbasecontext());              final spannablestring s = new spannablestring(getbasecontext().gettext(r.string.sms_not_received));             linkify.addlinks(s, linkify.web_urls);             message.settext(s);             message.setpadding(10, 0, 4, 0);             message.setgravity(gravity.clip_horizontal);             message.setmovementmethod(linkmovementmethod.getinstance());                new alertdialog.builder(myclass.this)                .settitle("my message\nerror")                .setview(message)             .setpositivebutton(r.string.ok_text,new dialoginterface.onclicklistener() {                    public void onclick(dialoginterface dialog, int whichbutton) {                        finish();                 }                }).setcancelable(false).show();         }     } }; 

i think problem statement linkify.addlinks(s, linkify.web_urls);

earlier used work without statement. please help

if handler inside activity class, use class context instead of getbasecontext() when creating textview.

that use activity context , make problem disappear.
