Android error "android.app.Application does not implement dagger.android.HasActivityInjector"

I'm trying to run my app and every time I click on a button and it calls a specific Activity (ExtendedActivity) I get the following error :

Process: com.converter.android.dailycope, PID: 28573
                  java.lang.RuntimeException: Unable to start activity ComponentInfo{com.converter.android.dailycope/com.converter.android.dailycope.ui.extended.ExtendedActivity}: java.lang.RuntimeException: android.app.Application does not implement dagger.android.HasActivityInjector

                      at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2369)

The error is on line super.onCreate(savedInstanceState)

    public class ExtendedActivity extends BaseActivity<ActivityExtendedBinding, ExtendedViewModel> {

    @Inject
    ViewModelProvider.Factory mViewModelFactory;
    ActivityExtendedBinding mActivityStartBinding;
    private ExtendedViewModel mExtendedViewModel;

    private String caps, horos, tipo;
    private String data, prefString;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    (...)

The class where I have the HasActivityInjector


    public class Cope extends Application implements HasActivityInjector {

    @Inject
    DispatchingAndroidInjector<Activity> activityDispatchingAndroidInjector;


    @Override
    public void onCreate() {
        super.onCreate();

        DaggerExtendedComponent.builder().application(this).build().inject(this);

        if (BuildConfig.DEBUG) {
            Timber.plant(new Timber.DebugTree());
        }

    }


    @Override
    public AndroidInjector<Activity> activityInjector() {
        return activityDispatchingAndroidInjector;
    }
}

Can you please help me?

I faced the same issue exactly. Just clean and rebuild the project solved the issue.

If your implementation is correct then please check in manifest file if you have add/assigned the name of Application Tag.

 <application
    android:name=".base.BaseApplication"
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"/>

Your application class should implement HasActivityInjector. Use official documentation to setup dagger properly.
