Answer

This is normal error because the class ImageView doesn't contain a method setImageUrl, so you need to do a workaround for that by creating a class that extends ImageView and contains a method named setImageUrl that takes a String as parameter and set the image inside that method using Picasso library:

public class MyImageView extends ImageView {

    // ... here is the constructors
    public void setImageUrl(String url) {
        Picasso.get().load(url).into(this);
    }
}

and after that you can use it in the xml like this:

<com.yourPackage.MyImageView
    android:id="@+id/circleImageView"
    android:layout_width="100dp"
    android:layout_height="100dp"
    app:image_url="@{abc.picture.thumbnail}"
    />
