Jetnews sample

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, use the latest stable version of Android Studio. You can clone this repository or import the project from Android Studio following the steps here.

Screenshots

Screenshot

Features

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.

App scaffolding

Package com.example.jetnews.ui

JetnewsApp.kt arranges the different screens in the NavDrawerLayout.

JetnewsNavGraph.kt configures the navigation routes and actions in the app.

Main article list

Package com.example.jetnews.ui.home

This screen shows how to create different custom Composable functions and combine them in a list that scrolls vertically and horizontally.

See how to:

  • Use Rows and Columns to arrange the contents of the UI
  • Add a top app bar that elevates as the user scrolls
  • Use Material's Typography and ColorScheme to style the text
  • Use tonal elevation to make the Cards stand out from the background

Article detail

Package com.example.jetnews.ui.article

This screen dives into the Text API, showing how to use different fonts than the ones defined in Typography. It also adds a bottom app bar, with custom actions.

Interests screen

Package com.example.jetnews.ui.interests

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.

AppWidget powered by Glance

Package com.example.jetnews.glance

This package shows how to use Glance and write compose style code for AppWidgets.

See how to:

  • Use Row, Column, LazyColumn to arrange the contents of the UI
  • Use a repository from your existing app to load data for the widget and perform updates
  • Configure android:updatePeriodMillis to periodically refresh the widget
  • Use androidx.glance:glance-material3 library to create a custom color scheme with GlanceTheme and use dynamic colors when supported
  • Tint Images to match the color scheme
  • Launch an activity on click using actionStartActivity

Data

The data in the sample is static, held in the com.example.jetnews.data package.

Instrumented and Robolectric tests

UI tests can be run on device/emulators or on JVM with Robolectric.

  • To run Instrumented tests use the "Instrumented tests" run configuration or run the ./gradlew connectedCheck command.
  • To run tests with Robolectric use the "Robolectric tests" run configuration or run the ./gradlew testDebug command.

Jetnews for every screen

Screenshot

We recently updated Jetnews to enhance its behavior across all mobile devices, both big and small. Jetnews already had support for “traditional” mobile screens, so it was tempting to describe all of our changes as “adding large screen support.” While that is true, it misses the point of having adaptive UI. For example, if your app is running in split screen mode on a tablet, it shouldn't try to display “tablet UI” unless it actually has enough space for it. With all of these changes, Jetnews is working better than ever on large screens, but also on small screens too.

Check out the blog post that explains all the changes in more details: https://medium.com/androiddevelopers/jetnews-for-every-screen-4d8e7927752

Features
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.
App scaffolding
Package com.example.jetnews.ui
JetnewsApp.kt arranges the different screens in the NavDrawerLayout.
JetnewsNavGraph.kt configures the navigation routes and actions in the app.
Main article list
Package com.example.jetnews.ui.home
This screen shows how to create different custom Composable functions and combine them in a list
that scrolls vertically and horizontally.
See how to:
  • Use Rows and Columns to arrange the contents of the UI
  • Add a top app bar that elevates as the user scrolls
  • Use Material's Typography and ColorScheme to style the text
  • Use tonal elevation to make the Cards stand out from the background
Article detail
Package com.example.jetnews.ui.article
This screen dives into the Text API, showing how to use different fonts than the ones defined in
Typography. It also adds a bottom app bar, with custom actions.
Interests screen
Package com.example.jetnews.ui.interests
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.
AppWidget powered by Glance
Package com.example.jetnews.glance
This package shows how to use Glance and write compose style code for AppWidgets.
See how to:
  • Use Row, Column, LazyColumn to arrange the contents of the UI
  • Use a repository from your existing app to load data for the widget and perform updates
  • Configure android:updatePeriodMillis to periodically refresh the widget
  • Use androidx.glance:glance-material3 library to create a custom color scheme with GlanceTheme
and use dynamic colors when supported
  • Tint Images to match the color scheme
  • Launch an activity on click using actionStartActivity
Data
The data in the sample is static, held in the com.example.jetnews.data package.
Instrumented and Robolectric tests
UI tests can be run on device/emulators or on JVM with Robolectric.
  • To run Instrumented tests use the "Instrumented tests" run configuration or run the ./gradlew connectedCheck command.
  • To run tests with Robolectric use the "Robolectric tests" run configuration or run the ./gradlew testDebug command.
Jetnews for every screen
Screenshot
We recently updated Jetnews to enhance its behavior across all mobile devices, both big and small.
Jetnews already had support for “traditional” mobile screens, so it was tempting to describe all of
our changes as “adding large screen support.” While that is true, it misses the point of having
adaptive UI. For example, if your app is running in split screen mode on a tablet, it shouldn't try
to display “tablet UI” unless it actually has enough space for it. With all of these changes,
Jetnews is working better than ever on large screens, but also on small screens too.
Check out the blog post that explains all the changes in more details:
