Question

我正在开发一个应用程序，我需要在Android和PC之间建立通信，以通过Wi-Fi传输一些数据。我可以通过wifi在两台PC之间进行通信。因此，PC端的代码已准备就绪。我需要一个从android端使用Wifi的参考。类似于蓝牙聊天的东西很有帮助。我能够扫描Android中存在的Wifi网络，但无法继续进行。干杯

这个收到一个文件

private String ReceiveFile() {

    try {
        ServerSocket socket = new ServerSocket(port);
        socket.setSoTimeout(5000);
        Socket os = null;

        try {
            os = socket.accept();
        } catch (SocketTimeoutException t) {
            if (!socket.isClosed()) socket.close();
            return "TIMEOUT";
        }

        InputStream bos = os.getInputStream();
        FileOutputStream fos = new FileOutputStream(FILENAME);
        DataOutputStream bw = new DataOutputStream(fos);

        int Total = 0;
        byte[] buffer = new byte[4096];
        int read;
        while (true) {
            read = bos.read(buffer);
            if (read <= 0) break;
            bw.write(buffer, 0, read);
            Total = Total + read;
        }

        if (!socket.isClosed()) socket.close();
        return "SUCCESS";
    } catch (Exception e) {
        e.printStackTrace();
        return "FAILURE";
    }
}

如果不知道你想要实现的目标，很难更具体，但这个片段会收到短暂的数据突发。

        DatagramSocket serverSocket = new DatagramSocket(PORTNUMBER);
        byte[] receiveData = new byte[50];

        DatagramPacket receivePacket = new DatagramPacket(receiveData, receiveData.length);
        serverSocket.setSoTimeout(5000);
        serverSocket.receive(receivePacket);
                    serverSocket.close();
