Unable to display images from Firebase(using glide)

Before adding material design it was working, but after changing my layout(Nothing changed about imageview) I am unable show images.

public class DownloadFile extends AppCompatActivity {

ImageView imageview;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_download_file);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);

FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Snackbar.make(view, "Wait for the action", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
yukle();
}
});


}

public void yukle(){
FirebaseStorage storage = FirebaseStorage.getInstance();
StorageReference storageRef = storage.getReference();
StorageReference riversRef = storageRef.child("images/pic.jpg");

imageview=(ImageView)findViewById(R.id.imageView);


Glide.with(this)
.using(new FirebaseImageLoader())
.load(riversRef)
.into(imageview);
}
}


I am getting the error below

At Firebase side here is my rules

service firebase.storage {
match /b/{bucket}/o {
match /{allPaths=**} {
allow read: if true;
allow write: if true;
}
}
}

Well as your stacktrace indicates the imageview you are passing in Glide is null. So the id that you set as a parameter in findViewById must be wrong. Ensure that you pass the correct id, otherwise post your xml so we have more info.
