我已经判断出当我按下Home键的时候程序没有退出，只不过是从前台变为后台运行。但是，问题是：当程序退到后台时候，headsup就不展示了，只是通知栏上有消息推送的展示。
请大家有知道的给予点思路，非常感谢！

你把代码放在 ui线程试试

你好，这个悬浮窗效果在android 5.0 的手机上，一旦退出前台就无法展示了，而在6.0上如果设置了 .setFullScreenIntent(pendingIntent, false) 这个属性，不管是true，还是false，都没有通知，而是直接就跳转了，pendingIntent 设置的界面了，但是如果不设置就只是普通的通知效果而已。想问下，怎么解决
