- io.realm.mongodb.AppConfiguration

```
public class AppConfiguration
extends Object
```
A AppConfiguration is used to setup a MongoDB Realm application.
Instances of a AppConfiguration can only created by using the AppConfiguration.Builder and calling its AppConfiguration.Builder.build() method.
Configuring a App is only required if the default settings are not enough. Otherwise calling new App("app-id") is sufficient.
