@Taiti77 that's really not enough information to debug this problem, please provide some steps for how to reproduce and information on what you have tried already.

taskSnapshot.getDownloadUrl() is deprecated, which is used in NewPostUploadTaskFragement.java class.
getDownloadUrl() shown in red color.

@Taiti77 ah yes you're right. That's a bug in this code. getDownloadUrl used to return a Uri but now returns a Task because it's async. So we will have to change that.

[Taiti77]

Aah, ok.

Hey guys I see the issue but If you gonna update to firebase 15.0.0 or above its again changed so better do the final version that looks like this

UploadTask uploadTask = imageRef.putBytes(data);
            uploadTask.continueWithTask(new Continuation<UploadTask.TaskSnapshot, Task<Uri>>() {
                @Override
                public Task<Uri> then(@NonNull Task<UploadTask.TaskSnapshot> task) throws Exception {
                    if (!task.isSuccessful()) {
                        completionHandler.onFailure("");
                    }
                    return imageRef.getDownloadUrl();
                    // Continue with the task to get the download URL
                }
            }).addOnCompleteListener(new OnCompleteListener<Uri>() {
                @Override
                public void onComplete(@NonNull Task<Uri> task) {
                    if (task.isSuccessful()) {
           // -> URL             Uri downloadUrl = task.getResult();
                        updateRoomImage(roomId, downloadUrl.toString());
                        completionHandler.onSuccess(downloadUrl.toString(), 
                        FirebaseObserverType.CHILD_ADDED);
                    } else {
                        completionHandler.onFailure("");
                    }
                }
            });
