Set timeout function with AsyncTask [Android] -

in case, button pressed , process timeout. when button clicked verify accno web services, if verification (progressdialog) on 5 seconds stop , display alertdialog notice user "timeout".

but have not idea when in testing 1 milliseconds, in logically pause in alertdialog until pressed, display dialog in milliseconds auto dismiss , intent next activity. here code:

@override protected void oncreate(final bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_information3);  btn_next.setonclicklistener(new view.onclicklistener() {         @override         public void onclick(view v) {             if (title.gettext().tostring().equals("info")) {                 infoasynctask infoasynctask = new infoasynctask();                 try {                     infoasynctask.execute().get(1, timeunit.milliseconds);                 } catch (interruptedexception e) {                     e.printstacktrace();                 } catch (executionexception e) {                     e.printstacktrace();

                    alertdialog.setmessage("verify timeout. please try again.");                      alertdialog.setpositivebutton(android.r.string.yes, new dialoginterface.onclicklistener() {                         @override                         public void onclick(dialoginterface dialog, int which) {                             dialog.dismiss();

get() method block ui thread , guess don't want this.

you should implement cancel mechanics in doinbackground , call asynctask.cancel() timeout [like that](https://developer.android.com/reference/android/os/handler.html#postdelayed(java.lang.runnable, long))

final handler handler = new handler();     handler.postdelayed(new runnable() {       @override       public void run() {         asynctask.cancel();       }     }, 1); 

be aware there many gotchas asynctask, check article.
