I have an object like so:

```
public class SubredditAddition extends RealmObject {

    @PrimaryKey
    private String mSubredditName;

    private ObservableArrayList<Keyword> mKeywords = new ObservableArrayList<>();
}

```

When I try to compile the program, I get the following error from Gradle:

```
Error:(13, 8) error: Field "mKeywords" of type "android.databinding.ObservableArrayList<Keyword>" is not supported.

Warning:Unclosed files for the types '[io.realm.SubredditAdditionRealmProxy]'; these types will not undergo annotation processing

```

Is there any way I can store an ObservableArrayList in realm?
