中断OutputStream - Android

Question

我使用这类来上传HTTP中的文件，我的问题是，当我从路由器中删除lan电缆时，上传块作为写调用块出现，下面显示了它的确切位置，我尝试中断线程，但这也没有帮助。

现在的问题是我如何打断outputStream？

public void addFilePart(String fieldName, File uploadFile)
        throws IOException {
    ...
    //removed code from here for clarity.
    //Can be found in the link above

    FileInputStream inputStream = new FileInputStream(uploadFile);
    byte[] buffer = new byte[4096];
    int bytesRead = -1;
    while ((bytesRead = inputStream.read(buffer)) != -1) {
        //The code stuck here.
        //using if (Thread.interrupted()) doesn't help
        //as the write blocks when the network cable 
        //removed from the router
        outputStream.write(buffer, 0, bytesRead);
    }
    outputStream.flush();
    inputStream.close();

    writer.append(LINE_FEED);
    writer.flush();    
}

到目前为止，我找到的最好的解决方案是从另一个线程执行HttpURLConnection.disconnect()，这似乎很好。
