在logCat中获取"[CDS] shutdownInput in read“

Question

我有一个我正在开发的android应用程序，在某个阶段，我得到了

是否在我的日志查看器中持续显示" [CDS]shutdownInput in read "？

这需要什么?我做错了什么才导致这条消息出现？

我有一个检查in流的线程。

Thread thread = new Thread(new Runnable() {
        public void run() {
            while (true) {
                mySocket.ReadFromSocket();
                try {
                    Thread.sleep(500);
                } catch (InterruptedException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
            }
        }


public byte[] ReadFromSocket() throws IOException {
    if (socketState == SocketState.CONNECTED) {
        byte[] buffer = new byte[1024];
        int noOfBytesRead = nis.read(buffer, 0, 1024); // This is blocking
        while (noOfBytesRead == -1) {
            noOfBytesRead = nis.read(buffer, 0, 1024); // This is blocking
            try {
                Thread.sleep(50);
            } catch (InterruptedException e) {
            }
        }
        byte[] tempdata = new byte[noOfBytesRead];
        System.arraycopy(buffer, 0, tempdata, 0, noOfBytesRead);
        return tempdata;
    } else {
        throw new IOException("Socket Not Connected");
    }
}

只要TCP连接尝试从缓冲区读取，而另一端已丢弃该连接，就会显示此错误消息。通常在超时后，如果您正在发送数据，out.checkError()将返回true
