Android app for every space enthusiast. Check upcoming and past SpaceX launches and find out more about each flight (e.g. data about payload).
Used:
- Kotlin
- Hilt
- Jetpack Compose
- Ktor
- Accompanist library
- Pagination
- Firebase Cloud Messaging
- MVVM architecture
- Git flow workflow
App is organized in MVVM architecture. Kotlin Coroutines and Flows were used to achieve reactive approach. Data is fetched from apis (like SpaceX Api) with usage of Ktor (this enables to use code in kotlin multiplatform app in future). Whole app is organized with intent to be clean, scalable and easy to refactor. Also, SOLID rules were applied.

Checkout my other repo, which contains server side code of the project. Its purpose is to fetch info about upcoming launches and send FCM notifications if necessary. Android app subscripes to this topic and shows notifications. Written in Go.
Tests were created with usage of Truth library.
Sample test:
@Before
fun setUp() {
eventsApi = mock {
onBlocking { loadUpcomingEvents() } doReturn mock()
}
articlesApi = mock {
onBlocking { loadArticles(any()) } doReturn mock()
}
mapper = mock {
on { toSpaceEvents(any()) } doReturn listOf(
SpaceEvent(title = "title1", description = "desc1", imageUrl = null, newsUrl = null, videoUrl = null, type = null)
)
on { toSpaceArticles(any()) } doReturn listOf(
SpaceArticle(title = "title1", summary = "summary1", imageUrl = null, url = null)
)
}
repository = NewsRepositoryImpl(
eventsApi = eventsApi,
articlesApi = articlesApi,
mapper = mapper
)
}
@After
fun tearDown() {
unmockkAll()
}
@Test
fun `loadArticles calls articles api`(): Unit = runBlocking {
val numOfArticles = 10
repository.loadArticles(numOfArticles)
verify(articlesApi).loadArticles(numOfArticles)
}
@Test
fun `loadArticles calls mapper`(): Unit = runBlocking {
repository.loadArticles(1)
verify(mapper).toSpaceArticles(any())
