Android- start activity from service by sending already running process to background

I have a background service BGService , it displays an Activity BGServActivity when certain event occurs. I have override onBackPressed to finish the displayed Activity BGServActivity.

Suppose, UI of Application App_XYZ is currently displaying. And my service BGService is triggered by the event and BGServActivity is displayed. And When i press back it closes the current Activity BGServActivity and displays the previous UI from Application App_XYZ .

But i want the UI from App_XYZ to be sent to background when i start BGServActivity from my BGService.

My question is

Is there any special flag or something that i can do to send the previously displaying UI from another activity to sent to background before starting My BGServActivity from My service BGService.

I think i got solution.

First show the HOME Screen as goto10's solution

Intent intent = new Intent(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_HOME);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);

Then-after open my Activity BGServActivity

        Intent i = new Intent();
        i.setClass(getBaseContext(), BGServActivity.class);
        Bundle b = new Bundle();
        b.putBoolean("IS_FROM_SERVICE", true);
        //add extras
        i.putExtras(b);
        startActivity(i);

And its working... :D

If you want to force the user to go to the Home screen when your Activity closes, you can do this:

Intent intent = new Intent(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_HOME);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);

I advise against this though. The standard behavior when closing an activity should be to return to the previously viewed activity.
