Socket连接未关闭，然后返回Launchpad页面。

在返回Launchpad页面之前，需要确保所有Socket连接都关闭了。可以使用try-finally代码块来确保Socket连接最终被关闭。示例代码如下：

private Socket socket;
private BufferedReader reader;
private PrintWriter writer;

...

try {
    socket = new Socket("host", port);
    reader = new BufferedReader(new InputStreamReader(socket.getInputStream()));
    writer = new PrintWriter(socket.getOutputStream(), true);

    // Perform IO operations here using reader and writer
} catch (IOException e) {
    e.printStackTrace();
} finally {
    // Close resources here
    try {
        if (reader != null) {
            reader.close();
        }
        if (writer != null) {
            writer.close();
        }
        if (socket != null) {
            socket.close();
        }
    } catch (IOException e) {
        e.printStackTrace();
    }
}
