使用Koin时SavedStateHandle后台重启后取值为null的问题

我在ShareViewModel中引入了SavedStateHandle，在HomeFragment中从MainActivity获取该ShareViewModel并传入HomeViewModel。现在遇到的问题是：应用从后台重启后，从SavedStateHandle中获取的值为null，但重复后台重启操作约3次后，SavedStateHandle又能正常获取到值。

模块代码 #

Koin ViewModel模块 #

val viewModelModule = module {
    viewModel { ShareViewModel(get()) }
    viewModel { (shareViewModel: ShareViewModel) ->
        HomeViewModel(
            shareViewModel
        )
    }
}

ShareViewModel #

class ShareViewModel(
    val stateHandle: SavedStateHandle
) : ViewModel(), KoinComponent {
 val sharedResp: MutableLiveData<Resp?> = stateHandle.getLiveData(KEY_RESP, null)

   fun getSharedResp(): Resp? {
        return sharedResp.value
    }

   fun updateResp(resp: Resp) {
        sharedResp.value = resp
    }
}

MainActivity #

class MainActivity : BaseActivity(R.layout.activity_main) {
    private val shareViewModel: ShareViewModel by viewModel()
}

HomeFragment #

class HomeFragment : BaseFragment<FragmentHomeBinding>() {

    private val shareViewModel: ShareViewModel by activityViewModel()
    private val viewModel by viewModel<HomeViewModel> {
        parametersOf(shareViewModel)
    }
}

HomeViewModel #

class HomeViewModel(
    private val shareViewModel: ShareViewModel,
) 

复现步骤 #

• 开启手机“不保留活动”选项并运行应用
• 将应用切换至后台
• 重新启动应用
• SavedStateHandle取值为null，重复该循环约3次后值恢复

使用的依赖版本 #

• koin-core:3.4.3
• lifecycle-viewmodel-savedstate:2.5.1
