Supernova is a design system platform that manages your assets, tokens, components and allows you to write spectacular documentations for your entire teams. And because you found your way here, you are probably interested in its most advanced functionality - automatic hand-off of design and development assets, tokens and data in general. To learn everything Supernova, please check out our developer documentation

Android Exporter

The Android exporter allows you to produce production-ready code for all product styles (such as colors) defined inside your design system in such a way that you can immediately use them to style your application elements. Specifically, this exporter automates the coding of:

• Color definitions
• Text Styles
• Fonts
• Radii
• Measures

The exporter will generate a file per style type. Here's an example of the exporter ouput for a single 11 Regular Italic text style:

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <style name="_11RegularItalic">
        <item name="android:textSize">11sp</item>
        <item name="android:letterSpacing">0.3</item>
        <item name="android:fontFamily">@font/roboto_regular</item>
        <item name="android:textStyle">normal</item>
    </style>

</resources>

A corresponding font/roboto.xml file will be created:

<?xml version="1.0" encoding="utf-8"?>
<font-family xmlns:app="http://schemas.android.com/apk/res-auto">  

    <font
        app:fontStyle="normal"
        app:fontWeight="400"
        app:font="@font/roboto_regular" />

</font-family>    

Note: exporter doesn't provide required font files (.ttf, .otf). Please, download all necessary font files from your Design System Management system or Google Fonts service. After that, name them accordingly and put next to the corresponding font XML files.

For example above, a Roboto Regular font needs to be downloaded from https://fonts.google.com/, named as roboto_regular.ttf and placed next to font/roboto.xml file.

You can generate all production ready-code either manually using Supernova's VS Code extension, or automate your code delivery pipeline using Supernova Design Continuous Delivery.

Example Usage

Once you have run the exporter against your design system, you can start using the code in your codebase right away. Here are a few examples of how you can use the output of the Android exporter:

Using a text style

<TextView
    style="@style/_11RegularItalic"
    android:id="@+id/text_home"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginStart="8dp"
    android:layout_marginTop="8dp"
    android:layout_marginEnd="8dp"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent" />
