近期在项目上遇到了webview崩溃的问题，出现在app版本迭代之后。崩溃log如下：

从log看是有webview资源未找到。

分析与验证：

1.app调用webview的代码没有变化，说明调用逻辑本身没有问
题，但是webview所在的Activity由继承自Activity变成了继承自AppCompatActivity
2.可能是webview app太老旧，尝试安装新版本，实测问题解决

PS：
有一些文章提供的方法是自定义webview，根据版本返回不同的context，但是这个方法仅限于app层面，从系统层面而言，还是需要修改webview app。

google android源码自带的webview app分别如下：

点这里->7.1

点这里->8.0

点这里->9.0

点这里->10
