My upload() function and fetching uploaded data from Firebase storage :

private void upload() {

    if (filePath!=null) {

        final ProgressDialog progressDialog = new ProgressDialog(this);

        progressDialog.setTitle("Uploading...");

        progressDialog.show();



        final StorageReference ref = storageReference.child(new StringBuilder("images/").append(UUID.randomUUID().toString()).toString());

        uploadTask = ref.putFile(filePath);



        Task<Uri> urlTask = uploadTask.continueWithTask(new Continuation<UploadTask.TaskSnapshot, Task<Uri>>() {

            @Override

            public Task<Uri> then(@NonNull Task<UploadTask.TaskSnapshot> task) throws Exception {

                if (!task.isSuccessful()) {

                    throw task.getException();

                }



                return ref.getDownloadUrl();

            }

        }).addOnCompleteListener(new OnCompleteListener<Uri>() {

            @Override

            public void onComplete(@NonNull Task<Uri> task) {

                if (task.isSuccessful()) {

                    Uri downloadUri = task.getResult();

                    progressDialog.dismiss();

                    // Continue with the task to get the download URL

                    saveUrlToCategory(downloadUri.toString(),categoryIdSelect);

                } else {

                    Toast.makeText(UploadWallpaper.this, "Fail UPLOAD", Toast.LENGTH_SHORT).show();

                }

            }

        }).addOnSuccessListener(new OnSuccessListener<Uri>() {

            @Override

            public void onSuccess(Uri uri) {

                progressDialog.setMessage("Uploaded: ");

            }

        }).addOnFailureListener(new OnFailureListener() {

            @Override

            public void onFailure(@NonNull Exception e) {

                progressDialog.dismiss();

                Toast.makeText(UploadWallpaper.this, "" + e.getMessage(), Toast.LENGTH_SHORT).show();

            }

        });

    }

}

FOR THOSE WHO ARE USING LATEST FIREBASE VERSION taskSnapshot.getDownloadUrl() method is DEPRECATED or OBSOLETE !!

Try Using this it will download the image from FireBase storage

FireBase Libraries versions 16.0.1

Task<Uri> result = taskSnapshot.getMetadata().getReference().getDownloadUrl();

result.addOnSuccessListener(new OnSuccessListener<Uri>() {

      @Override

      public void onSuccess(Uri uri) {

             String photoStringLink = uri.toString();

      }

});

taskSnapshot.**getDownloadUrl**().toString(); //deprecated and removed

use below code for downloading Url

 StorageReference profileImageRef= FirebaseStorage.getInstance().getReference("profilepics/" +` abc_10123 + ".jpg");



profileImageRef.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>()

        {

            @Override

            public void onSuccess(Uri downloadUrl) 

            {                

               //do something with downloadurl

            } 

        });

for latest version try

profileImageUrl = taskSnapshot.getStorage().getDownloadUrl().toString();

Try using this:

taskSnapshot.getMetadata().getReference().getDownloadUrl().toString()

You wont get the download url of image now using

profileImageUrl = taskSnapshot.**getDownloadUrl**().toString();

this method is deprecated.

Instead you can use the below method

    uniqueId = UUID.randomUUID().toString();

    ur_firebase_reference = storageReference.child("user_photos/" + uniqueId);



    Uri file = Uri.fromFile(new File(mphotofile.getAbsolutePath()));

    UploadTask uploadTask = ur_firebase_reference.putFile(file);



    Task<Uri> urlTask = uploadTask.continueWithTask(new Continuation<UploadTask.TaskSnapshot, Task<Uri>>() {

        @Override

        public Task<Uri> then(@NonNull Task<UploadTask.TaskSnapshot> task) throws Exception {

            if (!task.isSuccessful()) {

                throw task.getException();

            }



            // Continue with the task to get the download URL

            return ur_firebase_reference.getDownloadUrl();

        }

    }).addOnCompleteListener(new OnCompleteListener<Uri>() {

        @Override

        public void onComplete(@NonNull Task<Uri> task) {

            if (task.isSuccessful()) {

                Uri downloadUri = task.getResult();

                System.out.println("Upload " + downloadUri);

                Toast.makeText(mActivity, "Successfully uploaded", Toast.LENGTH_SHORT).show();

                if (downloadUri != null) {



                    String photoStringLink = downloadUri.toString(); //YOU WILL GET THE DOWNLOAD URL HERE !!!!

                    System.out.println("Upload " + photoStringLink);



                }



            } else {

                // Handle failures

                // ...

            }

        }

    });

I still having this error. What might be wrong? I already changed the permissions, and users to anonymous.
