我在尝试使用Hilt和WorkManager将作品入队时遇到了一个异常:

Could not instantiate my.example.package.widget.ExampleWorker
                 java.lang.NoSuchMethodException: my.example.package.widget.ExampleWorker.<init> [class android.content.Context, class androidx.work.WorkerParameters]

14:26:51.737  E  Could not create Worker my.example.package.widget.ExampleWorker

下面是我的Worker类:

@HiltWorker
class ExampleWorker @AssistedInject constructor(
    @Assisted private val context: Context,
    @Assisted workerParameters: WorkerParameters,
    private val exampleUseCase: ExampleUseCase
) : CoroutineWorker(context, workerParameters) {

    companion object {

        private val uniqueWorkName = ExampleWorker::class.java.simpleName

        fun enqueue(context: Context) {
            val manager = WorkManager.getInstance(context)
            val requestBuilder = PeriodicWorkRequestBuilder<ExampleWorker>(
                Duration.ofMinutes(15)
            )

            manager.enqueueUniquePeriodicWork(
                uniqueWorkName,
                ExistingPeriodicWorkPolicy.UPDATE,
                requestBuilder.build()
            )
        }
    }

    override suspend fun doWork(): Result {
        exampleUseCase.invoke()
        return Result.success()
    }
}

我的HiltApp:

@HiltAndroidApp
class HiltApp : Application(), Configuration.Provider {

    // https://developer.android.com/training/dependency-injection/hilt-jetpack#workmanager
    @Inject
    lateinit var workerFactory: HiltWorkerFactory

    override fun getWorkManagerConfiguration(): Configuration =
        Configuration.Builder()
            .setWorkerFactory(workerFactory)
            .build()
}

在AndroidManifest.xml文件中,我按照教程删除了默认的初始化器:https://developer.android.com/guide/background/persistent/configuration/custom-configuration#remove-default

<provider
    android:name="androidx.startup.InitializationProvider"
    android:authorities="${applicationId}.androidx-startup"
    tools:node="remove" />

我在worker中注入的简化类:

class ExampleUseCase @Inject constructor() {
    operator fun invoke() {}
}

以下是我的依赖:

implementation("com.google.dagger:hilt-android:2.48.1")
ksp("com.google.dagger:hilt-android-compiler:2.48.1")

implementation("androidx.hilt:hilt-work:1.0.0")
ksp("androidx.hilt:hilt-compiler:1.0.0")

implementation("androidx.work:work-runtime-ktx:2.8.1")
implementation("androidx.work:work-runtime:2.8.1")

Gradle插件版本:8.1.1,Kotlin版本:1.9.10
我在项目中更新了几个依赖项后遇到了这个异常,例如Gradle Plugin从7.4.1更新到8.1.1,Kotlin从1.8.0更新到1.9.10,Hilt从2.44.2更新到2.48.1,以及compile SDK从33更新到34等等。
我试图降级Hilt,但是,在这样做的时候,我遇到了新的异常,我相信这可能是由于所有这些升级库之间的版本不兼容造成的。
如果我从worker构造函数中删除exampleUseCase参数,NoSuchMethodException将被解析。但是,我在doWork()方法中需要此字段。我尝试将其作为lateinit var注入,但在调用时它尚未初始化。
我查了很多文件,但还是少了点什么。我将非常感谢任何帮助!
