Cannot update user profile specially photo in firebase android - firebase

Question

I am trying to update my user profile (specifically the photo) by making intent for choosepicker to select image from my gallery and upload it to my firebase authenticated storage. It's working almost fine: pics are getting uploaded to the path I describe.
The problem is I cannot retreive it back as I want. I want to update user profile pic and use UpdateProfileRequest but it's just not updating anything, nor can I retrieve anything.
Here's the code:
final ImageView photo = (ImageView) findViewById(R.id.photoURI);
if (photoUri == null) {
photo.setImageResource(R.drawable.user);
Toast.makeText(LoginActivity.this,"DP is Empty",Toast.LENGTH_SHORT).show();
} else {
photo.setImageURI(photoUri);
}
Button editPhoto = (Button) findViewById(R.id.edit_photo);
editPhoto.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("image/jpeg");
intent.putExtra(Intent.EXTRA_LOCAL_ONLY, true);
startActivityForResult(Intent.createChooser(intent, "Complete action using"), RC_PHOTO_PICKER);
}
});
Here is my activity result code
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RC_PHOTO_PICKER && resultCode == RESULT_OK) {
final Uri selectedImageUri = data.getData();
// Get a reference to store file at User_photos/<FILENAME>
StorageReference photoRef = storageReference.child(userID).child(selectedImageUri.getLastPathSegment());
// Upload file to firebase Storage
photoRef.putFile(selectedImageUri).addOnSuccessListener(this, new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
Uri downloadUrl = taskSnapshot.getDownloadUrl();
String imageUrl = downloadUrl.toString();
User user = new User(imageUrl);
databaseReferencenew.child(userID).child("Profile_Pic_URL").setValue(user);
FirebaseUser user2 = FirebaseAuth.getInstance().getCurrentUser();
UserProfileChangeRequest profileUpdates = new UserProfileChangeRequest.Builder()
.setDisplayName(mName)
.setPhotoUri(selectedImageUri)
.build();
user2.updateProfile(profileUpdates).addOnCompleteListener(new OnCompleteListener<Void>() {
#Override
public void onComplete(#NonNull Task<Void> task) {
Log.d(TAG, "User profile updated.");
Toast.makeText(LoginActivity.this,"User profile updated.",Toast.LENGTH_SHORT).show();
}
});
}
});
}
}
