java.net.UnknownHostException:主机是未解析的SOCKS代理

我在特定端口上设置了Tor,并希望通过该端口访问网站。下面的代码在Android 7.0中完美地工作,但是在Android 6.0中却给出了以下错误。可能是什么问题? Tor服务在我向其发送请求的特定端口上成功运行。 正在运行该库的示例代码(https://github.com/jehy/Tor-Onion-Proxy-Library

尝试更改

HttpGet httpGet = new HttpGet("http:google.co.in"); 

HttpGet httpGet = new HttpGet("http://google.co.in");  

URI uri = new URIBuilder()
            .setScheme("http")
            .setHost("google.co.in")
            .build();
HttpGet httpGet = new HttpGet(uri);

已更新-试试此

HttpHost target = new HttpHost("google.co.in", 80, "http");
HttpGet request = new HttpGet("/");
HttpResponse httpResponse = httpClient.execute(target, httpGet, context);

如果它不起作用,我不太确定。也许可以尝试使用此链接,希望对How to use HttpClientBuilder with Http proxy?
