Android-清单/匕首忽略了我的自定义Application类

Question

我有一个使用自定义应用程序类的Android应用程序，它看起来像这样：

AndroidManifest.xml

<application  
  android:allowBackup="true"  
  android:icon="@mipmap/ic_launcher"  
  android:label="@string/app_name"  
  android:networkSecurityConfig="@xml/network_config"  
  android:roundIcon="@mipmap/ic_launcher_round"  
  android:supportsRtl="true"  
  android:theme="@style/AppTheme"  
  android:usesCleartextTraffic="true"  
  android:name=".MyApplication"  
  tools:ignore="UnusedAttribute">

MyApplication.kt

class MyApplication : Application(), HasActivityInjector, HasSupportFragmentInjector, HasServiceInjector {  
      @Inject  
      lateinit var serviceInjector: DispatchingAndroidInjector<Service>  
      @Inject  
      lateinit var fragmentInjector: DispatchingAndroidInjector<Fragment>  
      @Inject  
      lateinit var activityDispatchingAndroidInjector: DispatchingAndroidInjector<Activity>  
      @Inject  
      lateinit var remoteConfig: FirebaseRemoteConfig  
      @Inject  
      lateinit var workerFactory: GrowWorkerFactory  

      override fun activityInjector(): AndroidInjector<Activity> = activityDispatchingAndroidInjector  

      override fun supportFragmentInjector(): AndroidInjector<Fragment> = fragmentInjector  

      override fun serviceInjector(): AndroidInjector<Service> = serviceInjector  

}

这是我的匕首组件类

interface MyApplicationComponent {  
  @Component.Builder  
    interface Builder {  
  fun build(): MyApplicationComponent  
  @BindsInstance  
  fun application(application: Application): Builder  
  fun dataSourceModule(module: DataSourceModule): Builder  
  fun serviceModule(module: ManagerModule): Builder  
  }  

  fun inject(app: MyApplication)  
}

构建正常完成，应用程序启动，但是，当到达SplashActivity类时，应用程序崩溃并抛出以下错误：

该应用似乎忽略了MyApplication类
