Hasactivityinjector Can Not Be Resolved In Android Dagger 2

I was trying to implement HasActivityInjector in my android application but it's showing me HasActivityInjector cann't be resolved. Below dependencies and plugin I have used in my

Solution 1:

In case anyone comes here after updating to 2.24, this was removed: https://github.com/google/dagger/commit/3bd8f707cb28fd0c5f3abb4f87658566f8b52c10.

You can use HasAndroidInjector instead.

Solution 2:

It's pretty late to answer but it might be useful for someone who is new to dagger world!

Its been replaced with HasAndroidInjector in order to avoid boilerplate of implementing multiple Dagger Interfaces like HasActivityInjector, HasServiceInjector etc, in your Application class. Now you only need to implement HasAndroidInjector like below:

classDaggerExampleApplication : Application(), HasAndroidInjector{

       @Injectlateinitvar androidInjector : DispatchingAndroidInjector<Any>

       overridefunandroidInjector(): AndroidInjector<Any> = androidInjector
       overridefunonCreate() {
         super.onCreate()
         //Your code
       }        
}

Solution 3:

In addition to @mbonnin and @Subhan's answer, starting version 2.24, Has{Activity,Fragment,Service,ContentProvider,BroadcastReceiver} are removed. If you still want to support this old implementation, use version 2.23 which supports both HasAndroidInjector and Has{Activity,Fragment,Service,ContentProvider,BroadcastReceiver}.

here's what it should look like on version 2.24

Application

classExampleApp: Application(), HasAndroidInjector {

    @Injectlateinitvar androidInjector: DispatchingAndroidInjector<Any>

    overridefunandroidInjector(): AndroidInjector<Any> = androidInjector

/..../

Activity

classExampleActivity: AppCompatActivity(), HasAndroidInjector {

    @Injectlateinitvar androidInjector: DispatchingAndroidInjector<Any>

    overridefunandroidInjector(): AndroidInjector<Any> = androidInjector

/..../

Fragment

classMoreFragment: Fragment(), HasAndroidInjector {

    @Injectlateinitvar androidInjector: DispatchingAndroidInjector<Any>

    overridefunandroidInjector(): AndroidInjector<Any> = androidInjector

/..../

Solution 4:

My dependencies looks like this:

//Dagger
implementation "com.google.dagger:dagger:${libs.dagger}"
implementation "com.google.dagger:dagger-android:${libs.dagger}"
implementation "com.google.dagger:dagger-android-support:${libs.dagger}"
kapt "com.google.dagger:dagger-compiler:${libs.dagger}"
kapt "com.google.dagger:dagger-android-processor:${libs.dagger}"

The support one is needed if you're using appcompat. And the ${libs.dagger} refers to the needed dagger version (e.g. 2.16). Read more about dependencies here.

Solution 5:

Could have been late late answer but new Dagger2 dependencies carries DaggerAppCompatActivity and DaggerFragment classes which are useful for injecting activities and fragments by itself. So, we no longer need HasActivityInjector, autoInjection methods or something like them.
