How to send/receive text between Android and Compu

问题:

I want to send a plain or rich text from/to Android <-> Computer, probably to clipboard but not necessarily. How can I do that? I don't want to email or create a file in order write text into it.

Does the Android API allow to do that somehow? Maybe via NFC or Bluetooth?

I'd like it to be wireless.

From your android device you can pass String to PC like this .

try {
    Socket socket = new Socket(DESTINATION_ADDRESS, DESTINATION_PORT);
    // Exmp : Socket socket = new Socket("192.168.0.101", 80);
    OutputStream outToServer = socket.getOutputStream();
    DataOutputStream out = new DataOutputStream(outToServer);
    out.writeUTF(SEND_STRING); 
    // Exmp : out.writeUTF("TEST");
    socket.close();

} catch (Exception e) {
    e.printStackTrace();
}

And from PC you have to receive the message and do action .

try {
    InetAddress IP = InetAddress.getLocalHost();
    ServerSocket serverSocket = new ServerSocket(1000);

} catch (UnknownHostException e) {
    e.printStackTrace();
}

// Run an infinite loop to check if the message is received or not.
while (true) {
        try {
            Socket clientSocket = serverSocket.accept(); 
            DataInputStream in = new DataInputStream(new BufferedInputStream(clientSocket.getInputStream()));
            String message = in.readUTF(); // Get the message which send from android device. 

            /* do other staff after getting the message . */
        }atch (Exception ex) {
            e.printStackTrace();
        }
}
