PLEASE HELP GUYS PLEASE
It took me three days to figure out what's the problem in my code. After knowing my mistake i am feeling very ashamed as well as happy that i figured, it out.
the mistake is in the adapter code,
in.putExtra(" videourl", post.getVideourl());
String ttr = in.getStringExtra("videourl");
the difference between above two code line is the, in first line there is space before the videourl and in the second line there is no space before videourl, and that's a problem. :-)

Where the RecyclerView is handled adapterName.notifyDataSetChanged (); you need to run.
In your case, the data is collected statically. The place where the data is processed is a different Activity.
After switching to the new screen and adding data, you will need to update your adapter in onResume if you want the relevant data to appear when you come back. Recyclerview will appear blank since there is no data in its initial state.
#Override
public void onResume() {
super.onResume();
adapter.notifyDataSetChanged();
}
im trying to retrieve data from firebase to detail activity. On the listview, it show perfectly. But when i click, the detail activity opened but still empty.

Here is the logcat when i click the task listview
And this is my database
I am trying to set up notification, but I can't add what I want: I would like the notification coming with sound/vibration, changing also the notification button logo.
Can anyone help me to setup notification? I am trying but it's not working.
The code below is working fine: no error. All notifications are shown, but with no sound / vibration.

If what you are trying to make is an in-app notification system, you can try ringing the sound on your own using RingtoneManager and Ringtone class as :
// to play sound for your custom notification on its arrival
Uri notificationToneUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
Ringtone notificationTone = RingtoneManager.getRingtone(this, notificationToneUri);
notificationTone.play();
//to stop
notificationTone.stop();
See this link for vibration
