在 Compose Multiplatform 中使用 Koin 在 ViewModel 中加载本机库时 JVM 崩溃

Question

我正在开发一个在 Linux (x86_64) 上运行的 Compose 多平台应用程序。我有一个类

DesktopNativeClient

加载本机库，如下所示：

class DesktopNativeClient { 
    private companion object {
        private val logger = Logger.withTag("NativeClient")

        private const val NATIVE_LIBRARY_PATH = "/path/to/lib.so"

        init {
            logger.d { "Loading native library" }
            System.load(NATIVE_LIBRARY_PATH)
            logger.d { "Loaded native library" }
        }
    }
}

当我在

main

函数中加载本机库时，一切正常：

fun main() = application {
    DesktopNativeClient()
    Window(
        onCloseRequest = ::exitApplication,
        title = "Title",
        state = rememberWindowState(
            width = ...,
            height = ...
        ),
    ) {
        MainApp()
    }
}

但是，当我尝试在通过 Koin 提供的

ViewModel

中加载本机库时，我总是在加载本机库时遇到 JVM 崩溃：

class AppViewModel {
    private val nativeClient = DesktopNativeClient()
    ...
}

ViewModel

的创建方式如下：

actual val platformAppModule = module {
    factory<BaseAppViewModel> {
        AppViewModel(
            defaultDispatcher = get(named(DispatchersNames.DEFAULT)),
            ioDispatcher = get(named(DispatchersNames.IO)),
            mainDispatcher = get(named(DispatchersNames.MAIN)),
        )
    }
}

并注入：

// in commonMain:
@Composable
expect inline fun <reified T : BaseAppViewModel> AppScreen(viewModel: T = koinNavViewModel())

// in desktopMain:
@Composable
actual inline fun <T : BaseAppViewModel> AppScreen(viewModel: T) {
...

崩溃日志：

• 在

  ViewModel

  中加载本机库时，什么可能导致 JVM 崩溃？

• 在

  Composable

  上下文中加载原生库或使用 Koin 时有什么具体注意事项吗？

• 仅当本地库加载到

  ViewModel

  （通过Koin注入）时才会发生崩溃。

• 在

  main

  函数中加载库时，应用程序运行良好。

• 我正在使用zulu-17.52

任何有关如何解决此问题的指导将不胜感激！

Answer 1

所以，我还没有找到它的确切原因，但只有在使用 Koin 创建对象时加载本机库时才会发生。

最简单的解决方案是在其外部加载库。
