<ImageView
            android:id = "@+id/imageView"
            android:layout_width = "wrap_content"
            android:layout_height = "wrap_content" />
        ImageView imageView = findViewById(R.id.imageView);

        RequestOptions options = new RequestOptions()
                .placeholder(R.drawable.ic_launcher_background)
                .error(R.drawable.ic_launcher_background);

        Glide.with(this).load("https://www.tutorialspoint.com/images/tp-logo-diamond.png").apply(options).into(imageView);

Answer

Add .apply(new RequestOptions() to continue with latest version. Just Replace below code:

Glide
 .with(this)
 .load(R.drawable.image_default_profile_picture)
 .apply(new RequestOptions()
 .placeholder(R.mipmap.ic_launcher_background)
 .fitCenter())
 .into(imageView);
