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。

...specifically in system-level assembly language. Knowledgeable in gaming input emulation and keyboard input simulation. Experience in backend applications is beneficial. Project Specifics: The emulator must not breach game firewall securities or require unauthorized system modifications such as disabling driver signature enforcement. It should operate successfully in the game, similar to devices like Arduino Leonardo or ESP32. The goal is to simulate pressing the Z1 keys solely through software, without external devices. Activation should be tied to the Caps Lock LED status—active when on, and inactive when off. Solutions utilizing 'keybd_event' and 'SendInput' do not meet the requirements of this project; a deeper, more intrinsic approach is necessary. ...
