            choose.setonclicklistener(new view.onclicklistener() {                 @override                 public void onclick(view v) { //i want confirm end user, did                 final alertdialog.builder builder = new alertdialog.builder(getapplication());                 builder.setmessage("are sure this?")                         .settitle("alert");                 builder.setpositivebutton("ok", new dialoginterface.onclicklistener() {                     @override                     public void onclick(dialoginterface dialog, int which) {                     }                 }); alertdialog dialog = builder.create();  // data insert db      }             });

what should do?

$badtokenexception: unable add window -- token null not application

because passing application context using getapplication() in alertdialog.builder.

to show alert current activity running pass car.this or v.getcontext() in alertdialog.builder
