If we're in a message thread, it'll navigate back to the channel. The handler sends a BackButtonPressed event to the MessageListViewModel, which will decide how to handle this event. Steps 5 and 6: We create a back button handler, and set the same behavior for the MessageListHeaderView and the Activity's OnBackPressedDispatcher.The MessageInputView needs to know when you’re editing a message or when you enter a message thread, which is also a piece of useful information for MessageListHeaderView. Steps 3 and 4: We coordinate the MessageListView with both MessageListHeaderView and MessageInputView.This loose coupling between components makes it easy to customize things, or only use the components you find necessary. Step 2: We bind these ViewModels to their respective Views.MessageInputViewModel - Responsible for composing and sending new messages.

MessageListViewModel - Loads a channel's messages, while also providing useful information about the current state of the channel.

MessageListHeaderViewModel - Provides useful information about the channel.

Step 5: We bind our ChannelListView to the ChannelListViewModel by calling the bindView function.Ĭonfiguring ChannelActivity involves a few steps, so let's review what's going on.

The documentation about Querying Channels covers this in more detail.

For the filter, we’re specifying all channels of type messaging where the current user is a member. We’re using the default sort option which orders the channels by last_updated_at time, putting the most recently used channels on the top.

Step 4: We configure the ChannelListViewModelFactory with a filter and a sort option.

For more information, see the Tokens & Authentication page.

In a real-world application, your authentication backend would generate such a token at login / signup and hand it over to the mobile app.

Step 3: We create a User instance and pass it to the ChatClient's connectUser method, along with a pre-generated user token, in order to authenticate the user.

For a production app, we recommend initializing this ChatClient in your Application class. Next, we add the offlinePluginFactory to the ChatClient with withPlugin method for providing offline storage capabilities. This key points to a tutorial environment, but you can sign up for a free Chat trial to get your own later.

Step 2: We create a connection to Stream by initializing the ChatClient using an API key.

The OfflinePlugin class employs a new caching mechanism powered by side-effects we applied to ChatClient functions.

Step 1: We create a StreamOfflinePluginFactory to provide offline support.
