From the developer document of Instant Apps

Installed apps can make themselves available to interact with instant through explicit intents.

And later, it is mentioned that instant apps cannot

Discover the list of installed apps on the device, unless the installed apps have made themselves discoverable to instant apps.

But I can't find the details about how to expose the component of an installed app or any part of an app, for that matter, to be visible (and accessible) by instant app. And any limitation on that? (supported component types and etc.)

At last, I figured out the syntax:

For Android O+, you can specify android:visibleToInstantApps="true" to the component.

For lower version of Android, add this meta-data to your <application> (not working for components):

<meta-data android:name="instantapps.clients.allowed" android:value="true" />
