每当调用Activity的onCreate（）回调时，都会调用存储库中的RefreshShows（）

I have following project in Github : https://github.com/Ali-Rezaei/TVMaze

我已经开始在示例应用程序中将Koin用作依赖项注入框架：

class TVMazeApplication : Application() {

    override fun onCreate() {
        super.onCreate()

        startKoin {
            androidContext(this@TVMazeApplication)
            modules(networkModule)
            modules(persistenceModule)
            modules(repositoryModule)
            modules(viewModelModule)
        }
    }
}

这是我的存储库类：

class ShowRepository(
    private val dao: ShowDao,
    private val api: TVMazeService,
    private val context: Context
) {

    /**
     * A list of shows that can be shown on the screen.
     */
    val shows = resultLiveData(
        databaseQuery = {
            Transformations.map(dao.getShows()) {
                it.asDomainModel()
            }
        },
        networkCall = { refreshShows() })

    /**
     * Refresh the shows stored in the offline cache.
     */
    private suspend fun refreshShows(): Result<List<Show>> =
        try {
            if (isNetworkAvailable(context)) {
                val shows = api.fetchShowList().await()
                dao.insertAll(*shows.asDatabaseModel())
                Result.success(shows)
            } else {
                Result.error(context.getString(R.string.failed_internet_msg))
            }
        } catch (err: HttpException) {
            Result.error(context.getString(R.string.failed_loading_msg))
        }
}

和我的ViewModel：

class MainViewModel(
    repository: ShowRepository
) : ViewModel() {

    private val _shows = repository.shows
    val shows: LiveData<Result<List<Show>>>
        get() = _shows
}

我在Activity中观察到LiveData：

viewModel.shows.observe(this, Observer { result ->
            when (result.status) {
                Result.Status.SUCCESS -> {
                    binding.loadingSpinner.hide() 
                    viewModelAdapter.submitList(result.data)
                }
                Result.Status.LOADING -> binding.loadingSpinner.show()
                Result.Status.ERROR -> {
                    binding.loadingSpinner.hide()
                    Snackbar.make(binding.root, result.message!!, Snackbar.LENGTH_LONG).show()
                }
            }
        })

当我单击“后退”按钮时，“活动”被销毁（但是应用实例仍然存在，因为我可以从最近的应用中访问它）。我期望的是在我再次启动应用程序时调用refreshShows（）方法，但是它从未被调用。

但是，当我通过清除最近的应用程序并启动该应用程序来破坏该应用程序实例时，就会调用refreshShows（）。

What should I do to have a call on refreshShows() every time onCreate() callback of Activity get called?

fun <T, A> resultLiveData(databaseQuery: () -> LiveData<T>,
                          networkCall: suspend () -> Result<A>): LiveData<Result<T>> =
    liveData(Dispatchers.IO) {
        emit(Result.loading<T>())
        val source = databaseQuery.invoke().map { Result.success(it) }
        emitSource(source)

        val result = networkCall.invoke()
        if (result.status == Result.Status.ERROR) {
            emit(Result.error<T>(result.message!!))
            emitSource(source)
        }
    }
