In your home activity, which I'm assuming is presented when the home button is clicked from somewhere else in the app, you can catch the back button press and exit the app. The following will show a dialog asking if the user really wants to exit.

@Override
public boolean onKeyDown(int keyCode, KeyEvent event)
{
    if (keyCode == KeyEvent.KEYCODE_BACK)
        showDialog(DIALOG_REALLY_EXIT_ID);

    return false;
}

@Override
protected Dialog onCreateDialog(int id)
{
    final Dialog dialog;

    switch(id)
    {
        case DIALOG_REALLY_EXIT_ID:
            dialog = new AlertDialog.Builder(this)
                .setIcon(R.drawable.icon)
                .setMessage("Are you sure you want to exit?")
                .setCancelable(false)
                .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int id) {
                        Home.this.finish();
                    }
                })
                .setNegativeButton("No", new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int id) {
                        dialog.cancel();
                    }
                }).create();
            break;
        default:
            dialog = null;
    }

    return dialog;
}
