Bring task to front on android.intent.action.USER_PRESENT

Question

BACKGROUND
I have a task (i.e. app) with multiple activities.

QUESTION
How do I bring a task to the front w/o re-ordering

Answer 1

Ok, I was able to get this to work by adding a static global variable in my main activity (activity_A). In onCreate I set isRunning = true, and onDestory = false. Then in my IntentReceiver class I check the isRunning to determine which activity to start:

            :
    if (intent.getAction().equals(Intent.ACTION_USER_PRESENT)) {
        if (GlobalVariables.isRunning) {
            activityClass = BringToFront.class;
        } else {
            activityClass = activity_A.class;
        }
    } else if (intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)) {
        activityClass = activity_A.class;
    }
            :
