In search fragment the username and full name is not being shown only follow/following button shows up. Though when I click on username it jumps to profile section so it's working properly. @Bhismydv Can you have a look at it please?

I have added google play services json file but I keep getting this error
ERROR: Failed to resolve: com.github.shts:StoriesProgressView:3.0.0

When I go to upload an image the upload fails and I get this error code. the PostActivity code is exactly what is given in GitHub.

after adding feature of post visible on home fragment my app crashes

double post in story part.
I copied this from the video and incorporated it into my app.

I need to display notification on my phone when a user post new story, and posts. And also in the Notifications Fragment when there is a new message in notifications fragment like commented message, liked your post and started following you. Please tell me the code to write and tell me where to write.

Thank you for your great tutorial.

    DatabaseReference reference = FirebaseDatabase.getInstance().getReference("Users").child(profileid);
    reference.addValueEventListener(new ValueEventListener() {
        @Override
        public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
            if (getContext() == null){
                return;
            }
           User user = dataSnapshot.getValue(User.class);


            Glide.with(getContext()).load(user.getImageurl()).into(image_profile);
            username.setText(user.getUsername());
            fullname.setText(user.getFullname());
            bio.setText(user.getBio());

        }

        @Override
        public void onCancelled(DatabaseError databaseError) {
