Image not load in Google map marker

I am trying to load image in Google map that I have fetched from Firebase Storage in marker window. The thing is, when I try to load it with Glide or Picasso, it's not loading in Google map. Every log I have in the code is visible in logcat. Am I doing something wrong here?

Here is my code

public class MapInfoWindowAdapter implements GoogleMap.InfoWindowAdapter {

    Context context;
    LayoutInflater inflater;
    private DatabaseReference mDatabase;
    private StorageReference storageReference;
    private Chalet chalet;
    private boolean query;
    private ImageView img;
    private String lat;
    private String log;

    public MapInfoWindowAdapter(Context context, LayoutInflater inflater) {
        this.context = context;
        this.inflater = inflater;
    }

    @Override
    public View getInfoWindow(Marker marker) {
        return null;
    }

    @Override
    public View getInfoContents(final Marker marker) {

        mDatabase = FirebaseDatabase.getInstance().getReference().child("chalets");
        storageReference=FirebaseStorage.getInstance().getReference();

        inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        View v = inflater.inflate(R.layout.marker_tag,null);

       final LatLng latlng = marker.getPosition();
       Double doubleLat = latlng.latitude;

         lat = String.valueOf(latlng.latitude);
         log = String.valueOf(latlng.longitude);
        Log.i("MarkerPostion",lat);

        img = (ImageView) v.findViewById(R.id.chaletImg);

       // final TextView textView = (TextView) v.findViewById(R.id.markerText);
        final Semaphore semaphore = new Semaphore(0);
       mDatabase.addValueEventListener(new ValueEventListener() {

            @Override
            public void onDataChange(DataSnapshot dataSnapshot) {

                Log.i("MarkerPostion","112211");
                for (DataSnapshot snapm: dataSnapshot.getChildren()) {
                    Log.i("MarkerPostion",snapm.child("latitude").getValue().toString());
                    Log.i("Key",snapm.getKey());
                    if ( lat.equals(snapm.child("latitude").getValue().toString()) && log.equals(snapm.child("longitude").getValue().toString()) ){
                        chalet = snapm.getValue(Chalet.class);
                        Log.i("MarkerPostion","9999");
                        break;
                    }
                }

                storageReference = FirebaseStorage.getInstance().getReference().child(chalet.getOwnerID()).child(chalet.getChaletNm()).child("1");
                storageReference.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {

                    @Override
                    public void onSuccess(Uri uri) {
                        Picasso.with(context).load(uri).into(img);
                        Log.i("MarkerPostion","2222");
                    }
                });
            }

            @Override
            public void onCancelled(DatabaseError databaseError) {

            }
        });       

        return v;
    }
}

Here is my XML file:

            android:adjustViewBounds="true"
            android:scaleType="centerCrop"
             />

    </LinearLayout>
