# builder

@JvmStatic
fun builder(): UserControllerBuilder

### Deprecated

Build and start SinchClient directly, instead of registering the user via UserController

Returns a UserControllerBuilder instance that can be used to create a new UserController, which is used to register new user and its Push token for the Sinch Managed Push to allow receiving incoming calls via push for this specified user on this very device. The UserControllerBuilder requires that a os.android.Looper is attached to the current thread on which the build methods invoked or CallbackHandler is provided via an optional parameter.

#### Return

A UserControllerBuilder instance.
