问题
I'm trying to implement notification in Android.
Now I have a problem, I don't want to have a PendingIntent that user will open any Activity. How can I do that?
回答1:
PendingIntent contentIntent = PendingIntent.getActivity(
    getApplicationContext(),
    0,
    new Intent(), // add this
    PendingIntent.FLAG_UPDATE_CURRENT);
    回答2:
The following works and seems more straightforward:
PendingIntent pi = PendingIntent.getActivity(context, 0, null, 0);
Having a notification without launching a subsequent Activity seems quite sensible to me - eg "Its time to get up!.
