调用YcShareElement.enableContentTransition()会导致如下异常：

看了下实现，是对Application对象注册ActivityLifecycleCallbacks回调，在所有Activity的onCreate()后设置activity.getWindow().requestFeature(Window.FEATURE_CONTENT_TRANSITIONS);
实际上在onCreate后Activity添加了ContentView后是不能再设置其Window对象的requestFeature()，所以请作者修复一下啦

activity嵌套fragment，从该fragment到另一个activity，该转场动画适用于这种场景吗

我用在自己的项目里
A进入B 动画执行 SharedElementCallback 执行
B finsh 返回A SharedElementCallback完全不执行了
会跟什么有冲突吗

回退到前一个页面过程中锁屏，出现如下无响应

共享元素动画如何同时对共享元素加上渐变效果？

机型是vivo nex s android9.0
如果在A页面不锁屏，前往B页面后锁屏，再解锁，返回A页面的动画是正常执行的，很奇怪。
我试着用原生的代码来写，也会出现这种BUG。
不知道大大能看看是什么问题，该怎么解决

在加载更多之后从数据源中回去当前点击的index的位置有时候是不对的，导致动画出现在别的item上错位了，怎么解决哦 ？
