# Vector Drawable crash in API < 21

In short, add this to the `onCreate` of `Application` class

```
AppCompatDelegate.setCompatVectorFromResourcesEnabled(true);
```

And use `ContextCompat`, `ResourcesCompat`, `AppCompatResources` or `VectorDrawableCompat` to load the vector image as drawable, don't use `ImageView.setImageResource()`. Sample example using Glide:

```
Drawable defaultAvatar = ContextCompat.getDrawable(context, R.drawable.ic_provider_default_circle);

Glide.with(viewHolder.iv_avatar)
      .load(imageURL)
      .apply(RequestOptions.circleCropTransform()
              .placeholder(defaultAvatar)
              .error(defaultAvatar))
      .transition(DrawableTransitionOptions.withCrossFade())
      .into(viewHolder.iv_avatar);
```
