Channel list Activity.

Channel list Adapter Standalone implementation that directly holds a ConversationListProvider without depending on a ProviderManager singleton.

Channel list Fragment Override entry points for subclasses:

• onCreateConversationListProvider — customize item rendering
• onCreateChannelListAdapter — customize Adapter
• onCreateViewModel — customize ViewModel
• subscribeUi — customize data binding
