Answer 1

I have just found a solution this issue: I created getPreviousIntent method and gave it to PendingIntent that`s all:

private Intent getPreviousIntent(Intent newIntent) {
    final ActivityManager am = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
    final List recentTaskInfos = am.getRecentTasks(1024,0);
    String myPkgNm = getPackageName();

    if (!recentTaskInfos.isEmpty()) {
        ActivityManager.RecentTaskInfo recentTaskInfo;
        for (int i = 0; i < recentTaskInfos.size(); i++) {
            recentTaskInfo = recentTaskInfos.get(i);
            if (recentTaskInfo.baseIntent.getComponent().getPackageName().equals(myPkgNm)) {
                newIntent = recentTaskInfo.baseIntent;
                newIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            }
        }
    }
    return newIntent;
}
