Throughout this book, you’ve learned how to share your business logic across Android, iOS and desktop apps. What if you could go a step further and also share your Compose UI?
That’s right — along with Kotlin Multiplatform, you now have Compose Multiplatform, which allows you to share your Compose UI with Android and desktop apps.
Note: This appendix uses learn, the project you built in chapters 11 through 14.
Updating your project structure
To follow along with the code examples throughout this appendix, download the Starter project and open 17-appendix-c-sharing-your-compose-ui-between-android-and-desktop/projects/starter with Android Studio.
Starter is the final version of learn from Chapter 14, without the iOS app and its platform-specific code. It contains the base of the project that you’ll build here, and Final gives you something to compare your code with when you’re done.
To share your UI, you’ll need to create a new Kotlin Multiplatform module. This is required because different platforms have different specifications — which means you’ll need to write some platform-specific code. This is similar to what you’ve done throughout this book.
Start by creating a new KMM library. You can easily do this by clicking the Android Studio status bar File, followed by New and New Module.
Then, select Kotlin Multiplatform Shared Module and set:
Module Name: shared-ui
Package Name: com.raywenderlich.learn.ui
iOS framework distribution: Regular framework
Click Finish and wait for the project to synchronize.
As you can see, there’s a new shared-ui module in learn. Open the settings.gradle.kts file to confirm that it was added to your project.
Android Studio only has direct support for KMM (Kotlin Multiplatform Mobile). So, when you try to add a new module, and you’re targeting other platforms — like desktop apps — you’ll need to manually add these targets.
Open shared-ui and rename the iosMain folder to desktopMain.
Now, open the shared-uibuild.gradle.kts and remove all the iOS references. Starting from the beginning of this file:
Moving towards the kotlin section, remove all the iOS targets:
Now on sourceSets delete all the iOS*Main and iOS*Test fields:
val iosX64Main by getting
val iosArm64Main by getting
val iosSimulatorArm64Main by getting
val iosMain by creating {
dependsOn(commonMain)
iosX64Main.dependsOn(this)
iosArm64Main.dependsOn(this)
iosSimulatorArm64Main.dependsOn(this)
}
val iosX64Test by getting
val iosArm64Test by getting
val iosSimulatorArm64Test by getting
val iosTest by creating {
dependsOn(commonTest)
iosX64Test.dependsOn(this)
iosArm64Test.dependsOn(this)
iosSimulatorArm64Test.dependsOn(this)
}
Now that there are no more iOS references, return to the kotlin section and under the android() target add:
jvm("desktop")
This is required — otherwise, you would only generate the shared-ui library for Android.
Finally, on the sourceSets configuration, add the desktopMain property to the bottom:
val desktopMain by getting
Synchronize the project. After it finishes, look at the project structure. It should be similar to this one:
Fig. C.1 - Project view hierarchy
When generating a KMM library, Android Studio also adds a Platform.kt file inside all folders and a Greetings.kt inside commonMain. You can remove these four files. They’re just placeholders, and they won’t be used in this appendix.
Sharing your UI code
Although the code of both platforms is quite similar, the Android app uses libraries that are platform-specific. Since the UI needs to be supported on both, there are a couple of changes you’ll need to make.

Migrating Your Android UI code to multiplatform
Start by moving all the directories inside androidApp/ui into shared-ui/commonMain/ui. Don’t move the MainActivity.kt file, since activities are Android-specific.

Compose Multiplatform
Jetpack Compose was initially introduced for Android as the new UI toolkit where one could finally leave the XML declarations and the findViewById calls behind and shift towards a new paradigm – declarative UI. It’s a more concise and modern approach — decoupled from API versions, it empowers you to create apps faster.

Different versions of Compose
The desktop app is already using Compose for desktop through the JetBrains Compose plugin. To make Android and desktop share the same UI, the shared-ui module needs to use the same one, instead of the Android version you’re using in the androidApp.

Now that shared-ui contains your app UI, it’s time to add the missing libraries. Open the build.gradle.kts file from this module and look for commonMain/dependencies. Update it to include:

Using third-party libraries
Although Compose Multiplatform is taking its first steps, the community is following closely, releasing libraries that help make the bridge between Android and desktop apps.
Fetching images
In the Android app, you were using Coil to fetch images. Unfortunately, it currently doesn’t support Multiplatform, so you’ll migrate this logic to a new one: Kamel.

learn was built using LiveData and ViewModels that are available in Android through the runtime-livedata library. Since it contains Android-specific code, it won’t be possible to use the same library in the desktop app.

The precompose library also handles Android and desktop navigation between different screens. In case of learn, the user can change between the tabs on the bottom navigation bar.

The accompanist libraries that the Android app uses are only being generated for this platform. Fortunately, the community once again comes to the rescue with a version that supports desktop. It was ported by the user Syer10, and you can find the repository on his GitHub.

Handling resources
Both platforms handle resources quite differently. Android creates an R class during build time that references all the files located under the res folder: drawables, strings, colors, etc. Although this gives you easy access to the application resource files, it won’t work on another platform.
Loading local images
To load local images, you’ll need to write this logic in Kotlin Multiplatform. This is necessary since Android uses the R class to reference images, and desktop uses the image path on the resources folder.

Using custom fonts
Both apps need to use the Bitter font. Previously, you moved all the folders from androidApp/res folder to commonMain/resources. If you open it, you’ll see there’s a set of bitter_*.ttf that represent the fonts your text can use.

Sharing strings
There’s currently no direct support for this feature. It’s true that you could follow a similar approach to the one you’ve made for sharing local images. However, this will be time-consuming and costly to maintain. On every new string, you need to create three different functions (one common and two at the platform level).
