手机版飞鸽传书:无线牵

    博客分类:
  • J2ME
阅读更多

 

 

【中文名】无线牵
【英文名】Wireless Linker
【组成】PC端(PC版)WirelessLinker-PC.jar、Mobile端(手机版)WirelessLinker.jar

 

 

【作者】火种工作室(Tinder Studio)
【邮箱】tinderstudio@163.com

 

 

【使用注意】
1、本软件使用J2ME开发,使用前请确认你的手机支持JSR75;
2、在传输文件给Mobile端时,请注意文件后缀,经本人在Nokia 5800上测试发现一些后缀是禁止传输的,
   所以传输前请先将后缀改为可用的后缀,如jpg,mp3等,然后再进行传输;
3、本软件在基于进行使用的,即手机版的使用是基于WLAN,所以请在使用前确认你的旁边局域网通讯的条件。
4、本软件不具备Nokia对一些特殊功能使用时应有的签名和证书,所以在使用过程会出现一些提示询问
   用户确认,均是Nokia的认证机制所致,不便之处,敬请谅解;
5、因为条件限制,本软件只在Nokia 5800真机上测试过,对于其他手机用户可自行尝试,如果不能使用只要
   卸载即可,不会残留信息。
6、因为本人能力有限,如果在使用过程中遇到异常的情况,希望您能多多提供意见和建议(联系方式请见
   上文),本人在此谢过。

7、有网友反应安装了JDK后运行PC端会出现can not find main class ,program will exit异常,这是因为本

    软件使用JDK1.6版本编译,所以请使用前确认你的JDK版本。

 

【版本】1.0
【功能说明】
1、显示局域网用户IP列表
2、局域网发送接收文件传输并支持文件覆盖
3、文件传输带进度条显示
4、支持PC-PC、PC-Mobile、Moblie-Mobile的文件传输

 

【使用步骤】

1、在电脑上打开PC端,并在手机上打开Mobile端,这时PC端的IP列表如图:

其中192.168.0.100是本机IP,192.168.0.101是Mobile端的IP;

2、点击Mobile端的IP,然后点击发送,会弹出文件选择框,选择你要传送的文件(注意一些后缀可能受限制,建议先改为jpg等图片后缀)

3、这时Mobile端会提示收到PC端的发送文件请求,选择“接收”,这时会弹出目录选择框(会提示是否允许文件访问,一路按是)点击“选择”确认保存文件的路径,程序就开始将文件从PC端传送给Mobile端,传输过程如下:

4、传输完毕后,程序提示如下:

5、从Mobile端传给PC端也类似,先选择相应的IP再点击“发送”按钮选择文件.....。

 

很抱歉,本来应该连同Mobile端的图片一起上传,但可惜我手头刚好没有照相机,手机又无法截图,所以请各位将就着看,希望这个软件能给大家提供一些方便(拿着一条数据线在USB跟手机上拔插真的很不爽,:))
