我正在使用工作管理器与剑柄,但得到以下错误。
我指的是Android教程https://developer.android.com/training/dependency-injection/hilt-jetpack
错误
java.lang.NoSuchMethodException: com.debug.check.TestWorker.<init> [class android.content.Context, class androidx.work.WorkerParameters]

分级版本:
implementation 'androidx.work:work-runtime-ktx:2.7.1'
// When using Kotlin.
kapt("androidx.hilt:hilt-compiler:1.0.0")
implementation 'androidx.hilt:hilt-work:1.0.0'
测试人员
@HiltWorker
class TestWorker @AssistedInject constructor(
@Assisted context: Context,
@Assisted chatParameters: WorkerParameters,
private val mainRepository: MainRepository
) : CoroutineWorker(context, chatParameters) {
companion object {
const val KEY_RESULT = "KEYRESULT"
}
override suspend fun doWork(): Result = coroutineScope {
try {
println("test")
mainRepository.refreshMovies()
} catch (e: Exception) {
Result.failure()
}
Result.success()
}
}
我的应用程序
@HiltAndroidApp
class MyApplication : Application(), Configuration.Provider {
@Inject
lateinit var workerFactory: HiltWorkerFactory
override fun getWorkManagerConfiguration() =
Configuration.Builder()
.setWorkerFactory(workerFactory)
.build()
override fun onCreate() {
super.onCreate()
}
}
主要活动
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main3);
WorkManager workManager = WorkManager.getInstance(this);
PeriodicWorkRequest periodicWorkRequest = new PeriodicWorkRequest.Builder(TestChatWorker.class
, 5, TimeUnit.SECONDS)
.addTag("test")
.build();
workManager.enqueueUniquePeriodicWork("test", ExistingPeriodicWorkPolicy.KEEP, periodicWorkRequest);
workManager.getWorkInfoByIdLiveData(periodicWorkRequest.getId()).observe(this, new Observer<WorkInfo>() {
@Override
public void onChanged(WorkInfo workInfo) {
if (workInfo != null) {
if (workInfo.getState() == WorkInfo.State.SUCCEEDED) {
String chatResult = workInfo.getOutputData().getString(TestWorker.KEY_RESULT);
}
}
}
});
}
}
- 它在初始化部分继续失败。* 我尝试将工作管理器降级到2.6,但仍然无法解决这个问题。我已经在manifest.xml中实现了。
<provider
android:name="androidx.startup.InitializationProvider"
android:authorities="${applicationId}.androidx-startup"
android:exported="false"
tools:node="merge">
<!-- If you are using androidx.startup to initialize other components -->
<meta-data
android:name="androidx.work.impl.WorkManagerInitializer"
android:value="androidx.startup"
tools:node="remove" />
</provider>

您应该检查两件事:
检查您正在使用的correct provider entry depending on the version,您正在使用AndroidManifest,这一个为我工作:
检查您的build.gradle上是否有这两个kapt依赖项(文档中没有提到这一点,这也是我遇到同样问题的原因):

在我的项目中,我为不同的任务使用了多个工人类。我也遇到了同样的问题,并通过在清单文件中添加
android:multiprocess="true"
“provider”标记修复了这个问题。
