[移动开发]Android设置网络音视频文件缓存至本地

    implementation 'com.danikula:videocache:2.7.1'

public class MyApplication extends Application {
    private HttpProxyCacheServer proxy;
    public Vibrator mVibrator;

    public static HttpProxyCacheServer getProxy() {
        return getInstance().proxy == null ? (getInstance().proxy = getInstance().newProxy()) : getInstance().proxy;
    }

    private HttpProxyCacheServer newProxy() {
        return new HttpProxyCacheServer.Builder(this)
                .cacheDirectory(getVedioFile())//缓存的文件夹，默认就不写
                .maxCacheSize(512 * 1024 * 1024)       // 512mb 最大大小，也可为最大个数
                .build();
    }

    @Override
    public void onCreate() {
        super.onCreate();
    }
    public static File getVedioFile() {
        String path = Environment.getExternalStorageDirectory().getPath() + "/cloudvideo";

        File file = new File(path);
        if (!file.exists()) {
            file.mkdir();
        }

        return file;

    }
}

 //设置文件缓存可以是mp4或mp3及其他音视频文件
  HttpProxyCacheServer proxy = MyApplication.getProxy();
String proxyUrl = proxy.getProxyUrl(“网络文件路径”);//videoUrl
//播放路径使用proxyUrl 
MediaPlayer.setDataSource(proxyUrl );
