现有APP具有通过WiFi 录影保存到手机上的功能。我司想再做一个APP在后台运行，这个APP的功能详细参考附件说明。
WiFi Camera作为AP，手机通过WiFi和WiFi Camera连接。 现成方案如下： WiFi Camera上需有两个按键：一个用于摄像，即按一下开始录像，拍摄一段时间（暂定一分钟）后，自动停止录像，并把录像文件放到手机上；另外一个按键，用于拍照，不管是不是在摄像中，都可以拍照，照片也存放在手机上。这些功能已经实现。 要求做一个简单APPS DEMO，功能如下： 把相机录的录像或拍照的照片，通过3G或4G网络传到云端服务器，用户可以在云端查看。
1、我有一个自己写的APP（ANDROID的） 2、这个APP有个“投影”按钮 3、点击“投影”就可以把这个APP的界面同步投影到投影仪上。点击“断开”则不再投影 4、投影和断开投影是要能控制的 5、投影仪是连接到一个ANDROID设备，这个设备可以接受APP发来的要求然后控制投影。（所以这个ANDROID设备可能也需要做相应的SERVER端程序） 6、APP和ANDROID设备是通过WIFI通信的 7、反应速度要快，延时不超过2秒 不用考虑向下兼容，你可以指定运行的ANDROID版本。 APP是运行在ANDROID平板上，参考三星的NOTE，你也可以指定其他平板。
