如果没有 @Provides-annotated 方法，就无法提供 android.content.Context

Question

在刀柄更新到 2.32-alpha 后，我收到以下错误。

即使在提供了相关元素之后，它仍在抱怨它。 我很确定它与范围有关，但无法整理出来，日志如下，

我认为您应该尝试使用 @ActivityScoped 或 @ActivityRetainedScoped 注释提供方法，以及我在您的代码中注意到的关于 AddLocationViewModal 的另一件事，我认为您应该使用 @HiltViewModel 注释它并使其类似于以下代码：

@HiltViewModel
class AddLocationViewModal @Inject constructor(
    private val savedStateHandle: SavedStateHandle,
    private val appCoroutineDispatchers: AppCoroutineDispatchers,
    private val reverseGeoCoding: ReverseGeoCoding,
    private val locationUseCase: LocationUseCase
) : ViewModel() {...}
