Hey guys hitting an issue trying to inject into a Worker with Hilt

🧵

[brandonmcansh]

E/WM-WorkerFactory: Could not instantiate am.planogr.planogram.editor.work.DownloadUseWorker

[brandonmcansh]

constructor

@HiltWorker
class DownloadUseWorker @AssistedInject constructor(
    @Assisted appContext: Context,
    @Assisted workerParams: WorkerParameters,
    private val api: DynamicUrlHitService,
) : CoroutineWorker(appContext, workerParams) {

[brandonmcansh]

work related deps update to 2.6.0-beta01 and hilt work is at 1.0.0

[brandonmcansh]

also have this in my manifest

[brandonmcansh]

<meta-data
                android:name="androidx.work.impl.WorkManagerInitializer"
                android:value="androidx.startup"
                tools:node="remove" />

[brandonmcansh]

injected dependency is also marked as a singleton

[brandonmcansh]

@Provides
    @Singleton
    fun providesDynamicUrlHitService(
        @Named("simple-retrofit") retrofit: Retrofit
    ): DynamicUrlHitService = retrofit.create(DynamicUrlHitService::class.java)

Have your Application class implement the Configuration.Provider interface, inject an instance of HiltWorkFactory, and pass it into the WorkManager configuration as follows:

[Nobel Dhar]

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

  @Inject lateinit var workerFactory: HiltWorkerFactory

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

[brandonmcansh]

yep forgot to mention that; that is present as well

[brandonmcansh]

good call out tho

[Nobel Dhar]

would like to see your factory class

this might help

I had this issue before. I was missing a hilt dependency in my build.gradle

This change made it work for me

Ah my metadata tag is wrong! Sweet I'll test it out on Monday. Thanks!
