App Startup Initializers

The UI Components library relies on Jetpack App Startup Initializers to initialize certain components. These run automatically when you include the UI Components library and start your application.

In some cases, you might wish to prevent the automatic initialization, for example, to decrease your app’s initial startup time. You can do this by following the Manually initialize components guide from the Android Developers documentation.

Specifically, you’ll have to do the following:

1. Disable the auto-initialization of our components, by adding the following to your Manifest:

   <provider
       android:name="androidx.startup.InitializationProvider"
       android:authorities="${applicationId}.androidx-startup"
       android:exported="false"
       tools:node="merge">
       <meta-data
           android:name="com.getstream.sdk.chat.startup.ThreeTenInitializer"
           tools:node="remove"
       />
       <meta-data
           android:name="io.getstream.chat.android.ui.common.ChatUIInitializer"
           tools:node="remove"
       />
   </provider>
   

2. Initialize them manually, before any of the Stream UI Components are used in your application.

AppInitializer.getInstance(appContext).run {
    initializeComponent(ThreeTenInitializer::class.java)
    initializeComponent(ChatUIInitializer::class.java)
}

AppInitializer.getInstance(appContext).initializeComponent(ThreeTenInitializer.class);
AppInitializer.getInstance(appContext).initializeComponent(ChatUIInitializer.class);
