Wi-Fi P2P数据传输

Question

我有一个Android应用程序，我想让它能够通过Wi-Fi p2p比较数据。 我理解连接方法（1.设置应用程序权限;设置广播接收器和P2P管理器;启动对等恢复;连接到对等） 但是在数据传输方面我遇到了问题。我的应用程序界面有一些下拉菜单 有几个选项可供选择。我想知道，我如何制作所选的选项（一旦应用程序用户相互连接） 能够比较数据并通知应用程序用户是否有相互选择 这段代码会起作用吗？

    //SERVER
public static class FileServerAsyncTask extends AsyncTask {

    private Context context;
    private TextView statusText;

    public FileServerAsyncTask(Context context, View statusText) {
        this.context = context;
        this.statusText = (TextView) statusText;
    }

    @Override
    protected String doInBackground(Void... params) {
        try {

            /**
             * Create a server socket and wait for client connections. This
             * call blocks until a connection is accepted from a client
             */
            ServerSocket serverSocket = new ServerSocket(8888);
            Socket client = serverSocket.accept();

            /**
             * If this code is reached, a client has connected and transferred data
                          */
            var pGender:String
            var pDesire:String
            var pAge:String
            var pRace:String
            var pWeight:String
            var pHeight:String
            var dGender:String = dGender.getValue(dGender.selectedItem.data);
            var pDesire:String = pDesire.getValue(pDesire.selectedItem.data);
            var dRace:String = dRace.getValue(dRace.selectedItem.data);
            var dAge:String = dAge.getValue(dAge.selectedItem.data);
            var dHeight:String = dHeight.getValue(dHeight.selectedItem.data);
            var dWeight:String = dWeight.getValue(dWeight.selectedItem.data);

            if (pGender == dGender.selectedItem.data && pDesire == pDesire.selectedItem.data && pRace == dRace.selectedItem.data && pWeight == dWeight.selectedItem.data && pHeight == dHeight.selectedItem.data)
            {
            trace (jump to frame 110 + vibrate);
            }
            else
            {
            trace (jump to frame 138 + vibrate + jump to frame 10) ; 
            }
            return results;

        }


            InputStream inputstream = client.getInputStream();
            copyFile(inputstream, new FileOutputStream(f));
            serverSocket.close();
            return f.getAbsolutePath();
        } catch (IOException e) {
            Log.e(WiFiDirectActivity.TAG, e.getMessage());
            return null;
        }
    }

    /**
     * Start activity that can handle the JPEG image
     */
    @Override
    protected void onPostExecute(String result) {
        if (result != null) {
            statusText.setText("File copied - " + result);
            Intent intent = new Intent();
            intent.setAction(android.content.Intent.ACTION_VIEW);
            intent.setDataAndType(Uri.parse("file://" + result), "image/*");
            context.startActivity(intent);
        }
    }
}

然后在客户端上我有这个：

 //CLIENT
Context context = this.getApplicationContext();
String host;
int port;
int len;
Socket socket = new Socket();
byte buf[]  = new byte[1024];
...
try {
    /**
     * Create a client socket with the host,
     * port, and timeout information.
     */
    socket.bind(null);
    socket.connect((new InetSocketAddress(host, port)), 500);

    /**
     * Create a byte stream from a JPEG file and pipe it to the output stream
     * of the socket. This data will be retrieved by the server device.
     */
    OutputStream outputStream = socket.getOutputStream();
    ContentResolver cr = context.getContentResolver();
    InputStream inputStream = null;
    /*varibles declaration
    */
    pGender.getValue(pGender.selectedItem.data);
    pDesire.getValue(pDesire.selectedItem.data);
    pRace.getValue(pRace.selectedItem.data);
    pAge.getValue(pAge.selectedItem.data);
    pHeight.getValue(pHeight.selectedItem.data);
    pWeight.getValue(pWeight.selectedItem.data);

    inputStream = cr.openInputStream(Uri.parse(DataProvider.getItemAt(pGender:String, pDesire:String, pRace:String, pAge:String, pHeight:String, pWeight:String):Object));
    while ((len = inputStream.read(buf)) != -1) {
        outputStream.write(buf, 0, len);
    }
    outputStream.close();
    inputStream.close();
} catch (FileNotFoundException e) {
    //catch logic
} catch (IOException e) {
    //catch logic
}

/**
 * Clean up any open sockets when done
 * transferring or if an exception occurred.
 */
finally {
    if (socket != null) {
        if (socket.isConnected()) {
            try {
                socket.close();
            } catch (IOException e) {
                //catch logic
            }
        }
    }
}
