我试图以这种方式在非常慢的连接上下载文件:

    java.net.URL url = new URL("https://X.X.X.X:8443/path/2f6b88cf2b70ee933197edfc9627a9bc/");
    HttpURLConnection connection = (HttpURLConnection)  url.openConnection();
    connection.setRequestMethod("GET");
    connection.setDoOutput(true);
    connection.setConnectTimeout(240 * 1000);
    connection.setReadTimeout(240 * 1000);
    long start = System.currentTimeMillis();
    Files.copy(connection.getInputStream(), new File("test.zip").toPath());
    System.out.println("Time: "+((System.currentTimeMillis() - start) / 1000) + " sec.");

我注意到由于某些原因(本机Windows套接字超时？)它总是在下载180秒后中断,没有任何例外.

在setConnectTimeout(...)或setReadTimeout(...)中设置的超时没有帮助.

我尝试使用wget下载该文件:

wget https://X.X.X.X:8443/path/2f6b88cf2b70ee933197edfc9627a9bc/ --no-check-certificate

如何从我的Android类中检测到,我从代码中调用的号码正忙,呼叫被拒绝了？我尝试使用PhoneStateListener,但没有像'busy'这样的状态.任何帮助将不胜感激.
