remove runonuithread
runonuithread(new runnable() { public void run() { your doinbackground invoked on background thread. don't need runonuithread network operation.
and return result in doinbackground , startactivity in onpostexecute.
edit:
as suggest prosper k upadate ui in onpostexecute not in doinbackground
loginerrormsg1.settext("invalid code"); also text edittext in activity , pass string doinbackground
btnlogin.setonclicklistener(new view.onclicklistener() { public void onclick(view view) { string code = inputcode.gettext().tostring(); new logintask_1().execute(code); } }); then
protected string doinbackground(string... args) { string value = args[0];
