撤回0.1.4版本就没有这个问题了

[cgspine]

虽然我没有重现这个crash，但猜测应该是修复 #399 造成的问题

[cgspine]

试试 0.2.1 版本？

[xtsxx]

试试 0.2.1 版本？

升级到0.2.1版本后已经解决，感谢

[szhangbiao]

使用0.2.2版本在弹出系统diolog（疑似第三方库的广告）后Activity和fragment都走了onSaveInstanceState，然后就又出现了这个bug

目前已撤回到0.2.1版本，准备再上线，如果后面还有这类问题会再回复

[szhangbiao]

撤回到0.2.1也报错

可升级到 0.3.0。 这个bug应该算是 fragmentManager 框架的内部bug，之前采取的 hack 方式来修复，但是效果不理想，现在 support library 28 已经修复了这个bug，因此 arch 去掉了之前的hack, 所以使用者需要升级 support library 到 28 或 使用 androidx.
