DaggerAppComponent not created

Question

With dagger 2.10 I used to be able to create the app component by doing

    sAppComponent = DaggerAppComponent.builder()             .appModule(new AppModule(this))             .sessionModule(new SessionModule())             .netModule(new NetModule())             .dataModule(new DataModule())             .build(); 

I was already using the AndroidInjector for Activities and everything was fine. Now I switched to 2.11 and I can't find the way to create the app component. In the google tutorial I see:

DaggerYourApplicationComponent.create()     .inject(this); 

to be added in the onCreate of the Application. In my case DaggerYourApplicationComponent = DaggerAppComponent. The problem is that DaggerAppComponent class isn't created anymore.

I have:

public class App extends android.support.multidex.MultiDexApplication implements HasActivityInjector {     @Inject DispatchingAndroidInjector<Activity> mDispatchingActivityInjector;     @Override     public void onCreate() {         super.onCreate();          sAppComponent = DaggerAppComponent.create().inject(this); //here the error 

and:

@Singleton @Component(modules = {         AppModule.class,         MainActivityModule.class,         ... }) public interface AppComponent {         void inject(App app);         ... } 

in the build.gradle file I have:

def daggerVer = 2.11 compile "com.google.dagger:dagger:$daggerVer" compile "com.google.dagger:dagger-android-support:$daggerVer" annotationProcessor "com.google.dagger:dagger-android-processor:$daggerVer" 

Answer 1

With the dependencies listed below everything works:

If you are using Kotlin

apply plugin: 'kotlin-kapt'  dependencies {     def daggerVer = 2.27 // or latest version      implementation "com.google.dagger:dagger:$daggerVer"     implementation "com.google.dagger:dagger-android-support:$daggerVer"     kapt "com.google.dagger:dagger-android-processor:$daggerVer"     kapt "com.google.dagger:dagger-compiler:$daggerVer" } 

If you are using Java:

dependencies {     def daggerVer = 2.27 // or latest version      implementation "com.google.dagger:dagger:$daggerVer"     implementation "com.google.dagger:dagger-android-support:$daggerVer"     annotationProcessor "com.google.dagger:dagger-android-processor:$daggerVer"     annotationProcessor "com.google.dagger:dagger-compiler:$daggerVer" }

In Kotlin, we have to add kapt compiler plugin to use Dagger 2.

In your app gradle, add this plugin

apply plugin: 'kotlin-kapt' 

And add dependencies as below

dependencies {     implementation "com.google.dagger:dagger:$latest_version"     kapt  "com.google.dagger:dagger-compiler:$latest_version"     implementation "com.google.dagger:dagger-android:$latest_version"     kapt  "com.google.dagger:dagger-android-processor:$latest_version"     implementation "com.google.dagger:dagger-android-support:$latest_version"     kapt  "com.google.dagger:dagger-android-support:2.12" }
