OK/Cancel dialog for Back Button

I am trying to make a dialog button that pops up when i am on the main activity and asks the user if they are sure they want to close the program. I'm not sure what to add in the //Action for the Yes button... Is there a better way to do this?

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {



    if (keyCode == KeyEvent.KEYCODE_BACK && event.getRepeatCount() == 0) {  
           AlertDialog.Builder alt_bld = new AlertDialog.Builder(this);
            alt_bld.setMessage("Are you sure you want to exit?")
            .setCancelable(false)
            .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int id) {
                // Action for 'Yes' Button



                }
            })
            .setNegativeButton("No", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int id) {
                //  Action for 'NO' Button

                    dialog.cancel();
                }
            });
            AlertDialog alert = alt_bld.create();
            // Title for AlertDialog
            alert.setTitle("Exit Game?");
            // Icon for AlertDialog
            alert.setIcon(R.drawable.icon);
            alert.show();


    return true;
    }

    return super.onKeyDown(keyCode, event);
}

you can use simple finish() statement in you action of yes Button to exit from activity

and you can also override onBackPressed method for that

You can finish Your Activity for example. calling finish() method.

Apart from that consider using DialogFragments (if You use compatibility library) or showDialog() method in Activity - this will prevent leakage of windows.
