Android错误“ android.app.Application无法实现dagger.android.HasActivityInjector”

Question

我正在尝试运行我的应用程序，每次我单击一个按钮，它都调用特定的活动（ExtendedActivity）时，都会出现以下错误：

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)

错误在线 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);
(...)

我有HasActivityInjector的类

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;
}

}

你能帮我么？

我解决了android:name在AndroidManifest.xml中添加的问题

如果您的实现正确，那么请在清单文件中检查是否已添加/分配了应用标签的名称。

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