I wrote such a code for data transfer. The imagecropper, picasso library is used. the compiler and android studio does not reveal any errors. imagecropper is launched, I select a photo, then the progress dialog goes on, but nothing happens.
I've tried searching the forums and YouTube but haven't been able to find anything.I expected that the photo will be sent to firebase storage and from there to imageview but nothing happens.

I'm creating an app that display notes list in a recyclerView. I connected the app with firebase authentication and realtime database.
The Realtime Database JSON tree looks like this:
The problem is that I want "Notes" to be part of "Users" which is not the case, because when I login to my app, I found the same Notes in every user account. I want the notes to be displayed for a specific user when they create them.

Please I need help on how should I modify my code to display the notes for a specific user when they create them. documentation links will be much appreciated.
you simply need to change this line of code from AddNotesActivity.java
mDatabase.child("Notes").child(id)
to
mDatabase.child("Users").child(userID).child("Notes").child(id)
and don't forget to retrieve the data in NotesActivity.java
databaseReference = FirebaseDatabase.getInstance().getReference().child("Users").child(userID).child("Notes");

Here the screen shot to help more how I wanted
I put my comment in answer field because of this restriction: 'You must have 50 reputation to comment'.
Anyway, back to your question. One solution would be to save the current user 'key' to a SharedPreference file. In your new Activity, use that 'key' to retrieve the data from Firebase.
EDIT: Added solution
Quoted: "...and I want to show one of these image in my ViewHolder activity as you can see the text view (name and score are showing) which is coming from a ranking Fragment activity..."
Solution: Search for fixme. In RankingViewHolder class, add:
public class RankingViewHolder extends ...
//...
public TextView name_text, score_text;
public ImageView profileImageView; //fixme
//...
public RankingViewHolder(View itemView) {
//...
score_text = (TextView) itemView.findViewById(R.id.score_text);
profileImageView = (ImageView) itemView.findViewById(R.id.profile_image_view); //fixme
//...
Inside populateViewHolder()
viewHolder.score_text.setText(String.valueOf(model.getScore()));
Picasso.with(getContext()) //fixme
.load(Common.currentUser.getUrlProfilePic()) //fixme
.into(viewHolder.profileImageView); //fixme
Inside RankingFragment class, since you are already using Common.currentUser.getUserName(), might as well create another variable under it to store the url link to the user's profile picture, and retrieve the link via Common.currentUser.getUrlProfilePic().
EDIT#2:
The images stored in FB storage have this links:
gs://FIXME_FIREBASE.com/images/userName/userNameback.jpeg
gs://FIXME_FIREBASE.com/images/userName/userNameprofile.jpeg
However to use in Picasso, need this kind of links:
https://firebasestorage.googleapis.com/v0/b/FIXME/o/FIXME/images/userName/userNameback.jpeg?alt=media&token=FIXME
Question is how to get that?
One solution is that after you successfully upload the image, get the download url (example below).
The tricky part is that the download url is not immediately available, and you have to use .getMetadata(), .getDownloadUrl() to do that.
Once the url is received, you have to figure out how to save this link to the user's profile in your FB database.
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
StorageMetadata storageMetadata = taskSnapshot.getMetadata();
StorageReference reference = storageMetadata.getReference();
reference.getDownloadUrl() // Get the download URL for the file
.addOnSuccessListener(new OnSuccessListener<Uri>() {
#Override
public void onSuccess(Uri uri) {
Log.i(TAG, uri.toString()); //fixme: save this to user's profile
}
});
}
Inside populateViewHolder, you are using Ranking model that contains the username and score.
Modify that Ranking model class to add an additional String variable urlProfilePic that contains the url to the user's image (above result), and generate the getter for it called getUrlProfilePic(). Then you can use it in this way inside the populateViewHolder:
viewHolder.score_text.setText(String.valueOf(model.getScore()));
Picasso.with(getContext())
.load(model.getUrlProfilePic()) //fixme
.into(viewHolder.profileImageView);
I face a problem when I send a comment, that comment does not appear in RecyclerView, I have to go back and reopen Activity again to see my reply.

There are two comments. To see these comment I have to go back and reopen this Activity.
I'm not 100% sure about this, but I think you're missing the mReplayBlogList.notifyDataSetChanged(); after the line mReplayBlogList.setAdapter(mAdapter); in getfirebaseData().
Maybe you could give it a try. Let me know if it solved :)
My Database in firebase is in this format
I need that if a user login then for that particular UID I need his associated department name. So How to take the department name as a String.I use this code to fetch department name
String u_id=auth.getCurrentUser().getUid();
mdatabase=FirebaseDatabase.getInstance().getReference().child("Users").child(u_id).child("department");
user=mdatabase.getKey();
By this i don't get the result.Please provide solution

I'm currently working on a chat apps using Firebase. For Firebase auth, I'm using getImageUrl() to get image Uri from Firebase User,
but Picasso Library does not load any image to show also not getting any error, but when I use Direct link, it works perfectly.

profileImg= (ImageView) findViewById(R.id.profileImage);

#Override
public void onAuthStateChanged(#NonNull FirebaseAuth firebaseAuth) {
FirebaseUser user = firebaseAuth.getCurrentUser();
if (user != null) {
// User is signed in
TextView name = (TextView) findViewById(R.id.profilenameTv);
name.setText(user.getDisplayName());
profileImg = (ImageView) findViewById(R.id.profileImage);
Picasso.with(getApplicationContext()).load(user.getPhotoUrl()).fit().centerCrop().into(profileImg);
