// Step 1: Add Dagger 2 dependencies in your build.gradle file dependencies { implementation 'com.google.dagger:dagger:2.x' annotationProcessor 'com.google.dagger:dagger-compiler:2.x' } // Step 2: Create a Dagger Module @Module public class AppModule { @Provides Context provideContext(Application application) { return application; } // Other dependencies... } // Step 3: Set up the Component interface @Component(modules = {AppModule.class}) public interface AppComponent { void inject(MyApplication app); } // Step 4: Create an Application class public class MyApplication extends Application { private AppComponent appComponent; @Override public void onCreate() { super.onCreate(); appComponent = DaggerAppComponent.builder() .appModule(new AppModule(this)) .build(); appComponent.inject(this); } } // Step 5: Inject dependencies where needed public class SomeClass { @Inject Context context; public SomeClass() { DaggerAppComponent.create().inject(this); } }
