my app webview app. when user turn on app, app must check net connection. , display dialog box if no network , app must close after showing dialog.

or

i don't want users see "webpage not available" page, if there no net connection, app must close after showing dialog box 1 button 'close'. or there way redirect users text in directory shows no net connection?

i need code only; other codes have been done , working properly.

just invoke finish() destroy activity in onclick() function of dialog. like:

... builder.setmessage('there no connection!! please close activity!') .setpositivebutton('close', new dialoginterface.onclicklistener() { public void onclick(dialoginterface dialog, int id) { finish(); } }) ...
