Cheap and reliable Node.js hosting starts at $3/month, and $1/month static HTML hosting

caching to disk while streaming,no wait;
offline work with cached data,no download again;
working with any media player on android(MediaPlayer,VideoView,ExoPlayer,ijkplayer...);
cache management(cache dir change,cache file rename,max cache files size limit, max cache files count limit...);
pre-download available,can pre-download the audio/video to avoid waiting.

Quick start

Just add dependency (MediaLoader was released in jcenter):

dependencies {
    compile 'com.vincan:medialoader:1.0.0'
}

and use new url from MediaLoader instead of original url:

String proxyUrl = MediaLoader.getInstance(getContext()).getProxyUrl(VIDEO_URL);
videoView.setVideoPath(proxyUrl);

Usage

Listen downloading status

Add callback to listen downloading status:

MediaLoader.addDownloadListener(String url, DownloadListener listener)

don't forget to remove listener to avoid memory leaks:

MediaLoader.removeDownloadListener(String url, DownloadListener listener)

Change initial configuration

You can change the default initial configuration with help of MediaLoaderConfig:

        MediaLoaderConfig mediaLoaderConfig = new MediaLoaderConfig.Builder(this)
                .cacheRootDir(DefaultConfigFactory.createCacheRootDir(this, "your_cache_dir"))//directory for cached files
                .cacheFileNameGenerator(new HashCodeFileNameCreator())//names for cached files
                .maxCacheFilesCount(100)//max files count
                .maxCacheFilesSize(100 * 1024 * 1024)//max files size
                .maxCacheFileTimeLimit(5 * 24 * 60 * 60)//max file time
                .downloadThreadPoolSize(3)//download thread size
                .downloadThreadPriority(Thread.NORM_PRIORITY)//download thread priority
                .build();
        MediaLoader.getInstance(this).init(mediaLoaderConfig);

Pre-download

Sometimes the MediaLoader doesn't work good in the case of poor network.So pre-download audio/video is a good idea to avoid no sense of waiting. DownloadManager is a good partner of MediaLoader.

Just use DownloadManager.enqueue(Request request, DownloadListener listener) to start and DownloadManager.stop(String url) to stop pre-downloading.

More useful method such as pause,resume and so on are available in DownloadManager.

See API list for more details.
