Component

@Component(modules = ApiModel.class)
public interface ApiComponent {
void inject(Activity app);
}

Module


@Module
public class ApiModel {
@Singleton
@Provides
TestApi providerApi(){
return new TestApi();
}
}


Activity


@Inject
TestApi api;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
DaggerApiComponent.builder().apiModel(new ApiModel()).build().inject(this);
findViewById(R.id.button).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Log.i("info","-----------log---------------------"+api.toString());
}
});
}

报错日志呢？还有你的Activity是直接Activity吗还是继承了其它Activity，inject方法中的参数必须是强类型。
