I got this Error while trying to update Metadata of file using Firebase Storage.

The code for updating Metadata is:

FirebaseStorage storage = FirebaseStorage.getInstance();
    final StorageReference storageRefNonThumbs = storage.getReferenceFromUrl(constants.FIREBASE_STORAGE_URL + "/notice/nonThumbs");
    final StorageReference storageRefThumbs = storage.getReferenceFromUrl(constants.FIREBASE_STORAGE_URL + "/notice/thumbs");

    UploadTask uploadTaskThumb = storageRefThumbs.child(timestamp + EmailPref).putFile(DOCUri);
    final StorageMetadata metadata = new StorageMetadata.Builder()
            .setContentType(DocMiMEType)
            .build();

storageRefThumbs.updateMetadata(metadata).addOnSuccessListener(new OnSuccessListener<StorageMetadata>() {
        @Override
        public void onSuccess(StorageMetadata storageMetadata) {
            // Updated metadata is in storageMetadata
            storageRefNonThumbs.updateMetadata(metadata)
                    .addOnSuccessListener(new OnSuccessListener<StorageMetadata>() {
                        @Override
                        public void onSuccess(StorageMetadata storageMetadata) {
                            // Updated metadata is in storageMetadata
                            //  Uri downloadUrlNonThumb = taskSnapshot.getDownloadUrl();

                            // saveData(editText, null, downloadUrlThumb.toString(), mTime, timestamp, null, null, null, downloadUrlNonThumb.toString());
                            Log.e("SahajLOG98", "Success in MEtaData@@22***");
                        }
                    })
                    .addOnFailureListener(new OnFailureListener() {
                        @Override
                        public void onFailure(@NonNull Exception exception) {
                            // Uh-oh, an error occurred!
                        }
                    });
        }
    })

This is a known issue with Android versions <= 4.0 (Ice Cream Sandwich and below) and Firebase Storage. A fix is coming in a future version of the SDK.
