Answer 1

    Settings.System.ALWAYS_FINISH_ACTIVITIES 

now is deprecated so you should use

    Settings.Global.ALWAYS_FINISH_ACTIVITIES.equals("1")

to check if this option is enabled

update(thanks Aviv Ben Shabat comment):

to handle all sdk versions I've created a method:

  public static boolean isFinishActivitiesOptionEnabled(Context context) {
    int result;
    if (Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN_MR1) {
        result = Settings.System.getInt(context.getContentResolver(), Settings.System.ALWAYS_FINISH_ACTIVITIES, 0);
    } else {
        result = Settings.Global.getInt(context.getContentResolver(), Settings.Global.ALWAYS_FINISH_ACTIVITIES, 0);
    }

    return result == 1;
}
