You could use custom LiveData like this:

class ActiveMutableLiveData : MutableLiveData() {

  private val values: Queue = LinkedList()

  private var isActive: Boolean = false

  override fun onActive() {
      isActive = true
      while (values.isNotEmpty()) {
          setValue(values.poll())
      }
  }

  override fun onInactive() {
      isActive = false
  }

  override fun setValue(value: T) {
      if (isActive) {
          super.setValue(value)
      } else {
          values.add(value)
      }
  }
}
