Android视频/音频缓存框架AndroidVideoCache

AndroidVideoCache是一个视频/音频缓存库,利用本地代理实现了边下边播,使用起来非常简单。

HttpProxyCacheServer是主要类,是一个代理服务器,可以配置缓存文件的数量、缓存文件的大小、缓存文件的目录和缓存文件命名算法,文件缓存均基于LRU算法,利用Builder来配置:

//配置缓存目录
public Builder cacheDirectory(File file);

//配置缓存文件命名规则
public Builder fileNameGenerator(FileNameGenerator fileNameGenerator) ;

//配置缓存文件大小
public Builder maxCacheSize(long maxSize) ;

//配置缓存文件数量
public Builder maxCacheFilesCount(int count) ;

建议以单列模式将HttpProxyCacheServer存放于Application中:

public class App extends Application {

    private HttpProxyCacheServer proxy;

    public static HttpProxyCacheServer getProxy(Context context) {
        App app = (App) context.getApplicationContext();
        return app.proxy == null ? (app.proxy = app.newProxy()) : app.proxy;
    }

    private HttpProxyCacheServer newProxy() {
        return new HttpProxyCacheServer(this);
    }
}

调用十分方便,只需要增加一行代码:

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

    HttpProxyCacheServer proxy = getProxy();
    String proxyUrl = proxy.getProxyUrl(VIDEO_URL);
    videoView.setVideoPath(proxyUrl);
}

private HttpProxyCacheServer getProxy() {
    return App.getProxy(getApplicationContext());
}
