问题描述：
项目中使用了表情包

https://github.com/w446108264/XhsEmoticonsKeyboard(emoji工具地址)

，代码混淆之后就会出现上述问题，就是在弹出表情键盘得时候奔溃，加上-keep public class还是会出现这个问题，问下大家在开发时使用emoji的时候有碰到过这个问题吗？要怎么解决呢

楼楼解决了没？

在你的model层 创建一个新的对象继承android.view.View.OnApplyWindowInsetsListener ， 然后在proguard-rules.pro中添加-keep class [PackageName].XX{*;}， XX这里指的是新的对象。

用的是低版本的sdk吧，这个方法版本比较高，所以混淆的时候认为这个方法没被开发者调用（实际上是被系统回调），所以就直接删掉了。

上面是我猜的。
