分享一个自己做的随时随地对内网的电脑进行开机、控制和关机的例子

在公司，或在外地如何才能达到随时随地对宿舍的电脑(在局域网内,IP是192.168.*.*)进行开机、控制和关机呢？通过magic packet可以唤醒局域网的电脑，但是想在公司远程唤醒宿舍的电脑怎么办(不在同一局域网内)？我想到的一个方法是通过手机，让一台手机(先叫手机A)放在宿舍连着wifi，这时候手机和宿舍的那台手机就在同一个局域网了，在公司用手机B给手机A发送一条开机指令的信息，手机A收到信息后发送magic packet就可以唤醒宿舍的电脑了。这时候再通过teamviewer(设置为开机启动)，就可以远程控制宿舍的电脑了，也可以通过teamviewer关机。这样就达到随时随地对宿舍的电脑进行开机、控制和关机的目的了。如果你换了新手机，旧手机放在宿舍也没用，不妨用来做这个，方便自己控制自己的电脑。下面是代码，经过在安卓4.2.1和4.0.4下测试可以达到上面所说的想法。
