How to quit the app from AlertDialog

I'm trying to do a very simple thing, show alert with only 1 button, if clicked I want the dialog to close and than the app to quit\finish()

currently I'm getting on the device the generic alert:

The application has stopped unexpectedly. Please try again

In the LogCat I get: Unable to pause activity

Here is the log:

                            dialog.dismiss();
                            finish();
                        }

AlertDialog.Builder dlg = new AlertDialog.Builder(context);
    dlg.setTitle(title);
    dlg.setMessage(message);
    dlg.setCancelable(false);
    dlg.setPositiveButton(buttonText, buttonClickListener);
    dlg.create();
    dlg.show();

Issue is you cannot finish activity from Pause mode.

Idea is to handle it with flag. Write the Exit code in Resume() method with the flag check. Enable the flag in Dialog.

Something like (below code is dummy),

boolean APP_EXIT_FLAG = false;
Resume(){

if(APP_EXIT_FLAG)
finish();

}

And your alert dialog code,

buttonClickListener = new AlertDialog.OnClickListener() {
                        public void onClick(DialogInterface dialog, int which) {

                           APP_EXIT_FLAG = true;
                            dialog.dismiss();
                        }

AlertDialog.Builder dlg = new AlertDialog.Builder(context);
    dlg.setTitle(title);
    dlg.setMessage(message);
    dlg.setCancelable(false);
    dlg.setPositiveButton(buttonText, buttonClickListener);
    dlg.create();
    dlg.show();

Hope it helps.
