在AOSPAndroid6.0上更新WebView
提问于 2017-10-10 09:39:45
我正在开发一个基于AOSPAndroid6.0 (Marshmallow)的设备。
为了使用最新的JavaScript，我想把标准的Android升级到最新的版本。
为此，我用最新版本取代了external/chromium-webview/prebuilt/arm64/webview.apk。
在frameworks/base/core/res/res/values/config.xml中，我还将config_webViewPackageName的值从com.android.webview更改为com.google.android.webview。但是当我试图启动一些使用webview (例如标准android浏览器)的应用程序时，我得到了这样的错误：

最后，我们发现问题在于webmusic.apk没有使用系统签名进行签名。这就是为什么它没有正确安装的原因。
