android - Error on ruOnUiThread inside asychtask -
i trying parse data server , compare data data in database... seems working fine... except getting same value comparing data change... i'll explain code...
in below code, there textviews tv3 , tv4... comparing data ie, shopid changed, shows value first array of json...
when tried debug, found the run() inside runonuithread calling after 2-3 loops... donno whats happening here... please somone ,e sort out issue...
edit: while debugging when skip each line not showing error... when try skip breakpoints using f9 shows error...
edit: 2: since code litle bit long, juz deleted som unwanted part...

} } there not need use runonuithread or other thread...because asynctask you..doinbackground work run on bgthread , onpostexecute work on mainuithread..
just check code...i haven't check..but work sure....
