[qingmei2]

这个问题我看一下，能否提供复现的操作呢？

[diswy]

@qingmei2 这个主要也是友盟收集上来的BUG，感觉出现崩溃的概率比较高，这边暂时不知道如何复现，如果有用户反馈的上来我这边及时提交上来

[qingmei2]

@diswy

这个是2.5.4的bug吗，还是2.5.3就有的问题呢？

[diswy]

@qingmei2 2.5.3就有该BUG，2.5.4依旧存在

[qingmei2]

@diswy

谢谢你提供的信息，我会尝试尽快定位到问题并修复。

[kinling]

我用的2.5.1，刚看到友盟上也收集到相同的bug

@qingmei2 不知大哥有空排查么，后台一直有这个问题在上报，应该是一个空指针引发的

[Roben1016]

@qingmei2 这个问题我这边复现过,但不是必现,在开发者模式中打开不保留活动, 然后打开图片选择的activity, 切换到其它应用, 然后重新返回APP偶尔重现, 是APP在相册页面被后台杀死后重新返回APP, 单例类SelectionSpec中的单例报空指针

[diswy]

这种有没有什么比较好的解决方案？

[zccguagua]

AndroidX项目使用2.5.6一点击就出现这个问题，后来仔细看了使用文档，使用3.0.0-beta02后可以正常使用
