I upload images using this code :

private void uploadFile(Bitmap bitmap) {
            FirebaseStorage storage = FirebaseStorage.getInstance();
            StorageReference storageRef = storage.getReferenceFromUrl("Your url for storage");
            StorageReference mountainImagesRef = storageRef.child("images/" + chat_id + Utils.getCurrentTimeStamp() + ".jpg");
            ByteArrayOutputStream baos = new ByteArrayOutputStream();
            bitmap.compress(Bitmap.CompressFormat.JPEG, 20, baos);
            byte[] data = baos.toByteArray();
            UploadTask uploadTask = mountainImagesRef.putBytes(data);
            uploadTask.addOnFailureListener(new OnFailureListener() {
                @Override
                public void onFailure(@NonNull Exception exception) {
                    // Handle unsuccessful uploads
                }
            }).addOnSuccessListener(new OnSuccessListener() {
                @Override
                public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                    // taskSnapshot.getMetadata() contains file metadata such as size, content-type, and download URL.
                    Uri downloadUrl = taskSnapshot.getDownloadUrl();
                    sendMsg("" + downloadUrl, 2);
                    Log.d("downloadUrl-->", "" + downloadUrl);
                }
            });

        }
