Я обновил код * не могу добавить в него никаких деталей. ниже приведен код onCreateView и код загрузки в мою базу данных. Пожалуйста, помогите очень нужно для моего проекта. Я пытался искать другие решения, которые на самом деле не работают.

Вот код в домашнем фрагменте:

imageFolder.putFile(saveUri)
    .addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
        @Override
        public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
            mDialog.dismiss();
            Toast.makeText(getActivity(), "Uploaded", Toast.LENGTH_SHORT).show();
            imageFolder.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
                @Override
                public void onSuccess(Uri uri) {
                    newBeach = new Beach();
                    newBeach.setDescription(beach_description.getText().toString());
                    newBeach.setImage(uri.toString());
                    newBeach.setName(beach_name.getText().toString());
                    newBeach.setPrice(beach_price.getText().toString());
                }
            });
        }
    })
    .addOnFailureListener(new OnFailureListener() {
        @Override
        public void onFailure(@NonNull Exception e) {
            mDialog.dismiss();
            Toast.makeText(getActivity(),""+e.getMessage(), Toast.LENGTH_SHORT).show();
        }
    })
    .addOnProgressListener(new OnProgressListener<UploadTask.TaskSnapshot>() {
        @Override
        public void onProgress(UploadTask.TaskSnapshot taskSnapshot) {
            double progress = (100.0 * taskSnapshot.getBytesTransferred() / taskSnapshot.getTotalByteCount());
            mDialog.setMessage("Uploaded " + progress + "%");
        }
    });

Вот onCreateView:

    @Nullable
@Override
public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {

    getActivity().setTitle("HOME");

    homeView= inflater.inflate(R.layout.fragment_home, container, false);

    recycler_menu = (RecyclerView)homeView.findViewById(R.id.recycler_menu);
    recycler_menu.setLayoutManager(new LinearLayoutManager(getContext()));


    database = FirebaseDatabase.getInstance();
    storage = FirebaseStorage.getInstance();
    storageReference = storage.getReference();
    beach =database.getReference("Beach Houses");
    cottages =database.getReference("Cottages");
    bigvenues =database.getReference("Big Venues");
    glamping =database.getReference("Glamping");


    beachHouseBTN = (Button) homeView.findViewById(R.id.beachHouseBTN);
    beachHouseBTN.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            menuID.equals("01");
            loadMenuBeach();

        }
    });

    cottagesBTN = (Button) homeView.findViewById(R.id.cottagesBTN);
    cottagesBTN.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            menuID.equals("02");
            loadMenuCottages();

        }
    });

    bigVenuesBTN = (Button) homeView.findViewById(R.id.bigVenuesBTN);
    bigVenuesBTN.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            menuID.equals("03");
            loadMenuBigVenues();

        }
    });


    return homeView;

}
