无法使用Hilt注入workmanager构造函数 [英] Can not inject workmanager constructor with Hilt

问题描述

我正在开发一个Android应用程序.并且我正在尝试使用带有workmanager构造函数的hilt，但是它不起作用，并给了我这个错误:

I'm developing an Android app. and I'm trying to use hilt with workmanager constructor but it does not work and gives me this error :

2020-08-18 19:01:09.989 18125-18759/com. E/WM-WorkerFactory: Could not instantiate example.android.app.database.DeleteNotesWorker
    java.lang.NoSuchMethodException: example.android.app.database.DeleteNotesWorker.<init> [class android.content.Context, class androidx.work.WorkerParameters]

        at java.lang.Thread.run(Thread.java:764)

这是工人阶级:

class DeleteNotesWorker @WorkerInject constructor(
    @Assisted context: Context,
    @Assisted workerParams: WorkerParameters,
    private val dao : NotesDao
) : CoroutineWorker(context, workerParams) {

    override suspend fun doWork(): Result {
        dao.deleteNotesInTrash()
         return Result.success()
    }


}

app模块:

@Module
@InstallIn(ApplicationComponent::class)
object AppModule {

    @Singleton
    @Provides
    fun getNotesDatabase(@ApplicationContext context: Context) =
        Room.databaseBuilder(context, NotesDatabase::class.java, NotesDatabase.DB_NAME).build()

    @Singleton
    @Provides
    fun getDoa(db: NotesDatabase) = db.notesDao()

}

应用程序类:

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

    @Inject
    lateinit var workerFactory: HiltWorkerFactory

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


}

build.gradle(应用程序):

build.gradle (app) :

 dependencies {

.......

 //Hilt
    implementation "com.google.dagger:hilt-android:2.28-alpha"
    kapt "com.google.dagger:hilt-android-compiler:2.28-alpha"
    
    //Hilt with workManager
    implementation 'androidx.hilt:hilt-work:1.0.0-alpha02'
    kapt 'androidx.hilt:hilt-compiler:1.0.0-alpha02'
}

build.gradle(项目):

build.gradle (project) :

 dependencies {
        classpath 'com.android.tools.build:gradle:4.0.1'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

    ............

        //Hilt
        classpath 'com.google.dagger:hilt-android-gradle-plugin:2.28-alpha'

        ..........
    }

在这种情况下我有做错什么吗?如果是，请帮助我

Did I do anything wrong in this case ? if yes please help me with it

推荐答案

根据

According to this documentation, you need to paste this code into your AndroidManifest to get Hilt's WorkManager Inject working.

<provider
    android:name="androidx.work.impl.WorkManagerInitializer"
    android:authorities="${applicationId}.workmanager-init"
    tools:node="remove" />

我刚才和您有同样的问题，并且此问题已解决

I had the same problem as you some moment ago and this fixed it
