Jetnews is a sample news reading app, built with Jetpack Compose. The goal of the sample is to showcase the current UI capabilities of Compose.
To try out this sample app, you need to use the Canary version of Android Studio 4.0, and import the project from the Android Samples following the steps here.
Compose is not available in earlier versions of Android Studio and downloading this github repo directly and opening it will most likely result in build errors.
This sample contains three screens: a list of articles, a detail page for articles, and a page to subscribe to topics of interest. The navigation from the the list of articles to the interests screen uses a navigation drawer.
JetnewsApp.kt arranges the different screens in the
NavDrawerLayout. It also implements a simple

See how to:

- Use elevation to make the

This screen dives into the Text API, showing how to use different fonts than the ones defined in
Typograhy. It also adds a bottom appbar, with custom actions.
This screens shows how to use Tabs and switch content depending on the selected tab. It
also includes a custom checkbox button, SelectTopicButton
that uses a
Toggleable composable function to provide
the on/off behaviour and semantics, while drawing a custom UI. The UI of the button is partly
drawn with low-level primitives and partly overlaying images. See also how to visualize
on and off, light and dark version in the Android Studio Preview.
