Android webview更新记录-aosp

一、下载

webview下载地址，感谢火哥分享，版本很全。

https://www.firepx.com/app/android-system-webview/

二、更新

external/chromium-webview/prebuilt

具体更新那个目录，需要查看编译架构

这个看你的lunch就行，这里我的是arm64，所以我下载最新webview最新apk后更改名称覆盖即可

三、修改默认包名

frameworks/base/core/res/res/xml/config_webview_packages.xml

<webviewproviders><!-- The default WebView implementation --><!-- <webviewprovider description="Android WebView" packageName="com.android.webview" availableByDefault="true"> --><webviewprovider description="Android WebView" packageName="com.google.android.webview" availableByDefault="true"></webviewprovider>
</webviewproviders>

四、编译一致性问题

编包可能会碰见可选依赖库error，导致编译失败，这里在bp文件中加入如下代码即可。

五、关于特权应用使用webview报错

只要在Activity的oncreate方法中调用hook函数就行了，切记一定要** 在setContentView之前调用** ，或者在** webVIew创建之前调用** ，不然还是会报错的。
