我用模拟器测试下

[oubowu]

模拟器Andorid 9,API28木有报错哎 你用的是真实的机子吗？

[pengjunhong]

@oubowu 系统版本：android P 报错：Invalid Region.Op - only INTERSECT and DIFFERENCE are allowed 我这边也使用模拟器 出现一样的问题

[pengjunhong]

@oubowu 作者你好 你可以直接模拟这个场景 把demo中的sdk升级到28 然后使用AndroidP的模拟器跑 问题就出来了

[pengjunhong]

暂时把c.clipRect(mClipBounds, Region.Op.UNION);换成 c.clipRect(mClipBounds, Region.Op.INTERSECT);没发现什么问题。

[oubowu]

明白了 是编译版本到28 谷歌改了canvas的源码了 只允许clipRect只允许INTERSECT and DIFFERENCE这两种模式了 我改下重新上传适配下

[oubowu]

改好了，可以升级看下
