CallbackReference

fun interface CallbackReference

A reference to a Mobile Payments SDK Callback that can be cleared to prevent memory leaks. It is recommended to clear the reference any time a lifecycle destroy event occurs (e.g. android.app.Activity.onDestroy or ViewModel.onCleared()). It can also be cleared when the Callback is no longer needed and should not be invoked.
