Moxy Fatal Exception-呼叫站点＃0引导方法的异常

Question

Moxy的示例代码无效https://github.com/moxy-community/Moxy源代码被分离到不同的文件中，但是现在呈现出来的目的是为了简化视图

空应用程序（没有MVP，它只有一个空白屏幕）有效但是，如果我像示例中那样添加代码，它会因致命异常而崩溃（下面提供）

interface ExplorerView : MvpView {
    @StateStrategyType(AddToEndSingleStrategy::class)
    fun foo()
}

@InjectViewState
class ExplorerPresenter : MvpPresenter<ExplorerView>() {
    fun loadFiles() {}
}

class ExploreActivity : MvpAppCompatActivity(), ExplorerView {
    @InjectPresenter
    internal lateinit var explorerPresenter: ExplorerPresenter

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_explorer)
        isPermissionsGranted()
    }

    private fun isPermissionsGranted() {
        explorerPresenter.loadFiles()
    }
}

我找到了一个对我有用的解决方案。我刚刚设置了启用的Java 8功能https://developer.android.com/studio/write/java8-support
