Android关于锁屏页和自定义通知栏的一些适配问题

1.锁屏页

实现思路

自定义锁屏页大多使用悬浮窗和弹出Activity的方式实现，这里我参考了QQ音乐和网易云音乐的实现方式，在锁屏页面弹出Activity。首先，动态注册一个广播接收器用于监听手机熄屏和亮屏的广播，在接收到熄屏广播后启动Activity，在这里启动Activity时，还涉及到一个权限问题，由于一些手机厂商都有自己的自定义权限，这里我选择所有的权限让用户手动去开启(权限要动态校验)。到这一步已经差不多实现了，最后就是一些细节问题，滑动解锁以及沉浸式实现

监听亮屏和熄屏广播的代码网上都有，这里就不多说了，重点是权限适配的问题，我几乎找遍了全网，整理出下面这个工具类，直接上代码
