悬浮球，提供一些快捷操作。比如一键静音，一键锁频，一键截屏，一键回桌面，手电筒等
代码中有参考意义的地方有：
1、自定义悬浮球，该悬浮球只能在一个圆形范围拖动(类FloatingView)
2、代码混淆(网上摘录,http://www.trinea.cn/android/android-proguard-tip-not-proguard/) (类NotProguard)
3、6.0以上动态权限申请(网上摘录) （类PermissionUtils）
4、三击事件处理 （类MainActivity中toggle方法中有实现）
5、悬浮窗实现 （类FloatingWindowManager）
6、截屏的实现 （类ScreenShotActivity）
