近期在項目上遇到了webview崩潰的問題，出現在app版本迭代之後。崩潰log如下：

從log看是有webview資源未找到。
分析與驗證：
1.app調用webview的代碼沒有變化，說明調用邏輯本身沒有問
題，但是webview所在的Activity由繼承自Activity變成了繼承自AppCompatActivity
2.可能是webview app太老舊，嘗試安裝新版本，實測問題解決
PS：
有一些文章提供的方法是自定義webview，根據版本返回不同的context，但是這個方法僅限於app層面，從系統層面而言，還是需要修改webview app。
google android源碼自帶的webview app分別如下：
