强制学习应用源码是一个类似于我要当学霸的强制性学习的小应用源码，不过本应用只会检测网络情况，并不会妨碍其他应用的使用，使用的时候先设置好开始时间和结束时间，然后退出，就可以了。软件会在后台运行， 在你设置的时间内，如果你打开网络上网，它就会播放音乐并震动提醒你要好好学习。关掉网络后，两秒钟，震动就会停止。此项目只有监控网络权限，震动权限，并没有网络连接权限，不会造成网络流量的消耗项目编译版本4.1.2默认编码GBK。(Compulsory learning application source code is a similar to me to when tyrants in the mandatory learning in small application source code, but this application will only detect network and does not interfere with other applications use, use the first set the start time and end time, and then exit, to the. Software will run in the background, in the time you set, if you open the Internet, it will play music and vibrate to remind you to learn. Turn off the network, after two seconds, the vibration will stop. This project only monitors network permissions, vibration permissions, and no network connection permissions, the network traffic will not cause the consumption of the project compiled version 4.1.2 default encoding GBK.)
