android - Dagger 2 : Is it possible to inject based on Android Version?

Question

是否可以使用Dagger2根据SDK版本注入(inject)具体实现？

例如

// MediaPlayerComponent.class
@Component(modules = {MediaPlayerModule.class}
public interface MediaPlayerComponent
{
    void inject(MediaPlayerUI ui)
}

// MediaPlayerUI.java
public class MediaPlayerUI
{
    @Inject
    public MediaPlayer mPlayer;
}

// GingerbreadMediaPlayer.java
public class GingerbreadMediaPlayer extends MediaPlayer {...}

// IceCreamSandwichMediaPlayer.java
public class IceCreamSandwichMediaPlayer extends MediaPlayer {...}

Answer 1

是的，只需决定在 MediaPlayerModule 模块中用 @Provides 注释的具体方法返回两个实现中的哪一个，返回通用 媒体播放器。
