Glide not working with AppCompatActivity?

Hi, I am trying to use glide with an AppCompatActivity. It works well if I use an Activity. But if I am extending from an AppCompatActivity, the image is not loaded (there is only a completely transparent imageview).

Any idea how to fix it? I am using Glide 4.12.0 and this code for loading the image:
```
Glide.with(activity)
.load(DOMAIN+this.url)
.placeholder(placeholder)
.diskCacheStrategy(DiskCacheStrategy.DATA)
.into(this.view);

}
```

Activity is of type AppCompatActivity (extending from it).
