java - bittorrent客户端:ttorrent不起作用

我想使用（“ /sdcard/file.torrent”）上已保存的.torrent文件开始简单下载。
我尝试过ttorrent，因为它是最简单的bittorrent客户端。
ttorrent on github.com
所以我尝试了这段代码，但是有错误...

String filePath = "/sdcard/file.torrent";
String downPath = "/sdcard/A";

Client client = new Client (
    InetAddress.getLocalHost(),
    SharedTorrent.fromFile(
    new File(filePath),
    new File(downPath)
    )
);

client.setMaxDownloadRate(0.0);
client.setMaxUploadRate(0.0);
client.download();
client.share(0);
client.waitForCompletion();

最佳答案

问题出在apache-commons lib中。我使用的是1.8（最新版本），但此ttorrent客户端1.2 version是必需的。

client.setMaxDownloadRate(0.0);
0.0设置下载速度无限制。但是下载速度太慢，Android uTorrent的功能更多。
