在 AOSP Android 6.0 上更新 WebView
Updating WebView on AOSP Android 6.0
我正在开发基于 AOSP Android 6.0 (Marshmallow) 的设备。
我想将标准 Android webview 更新到最新版本以使用最新的 JavaScript.
为此，我将 external/chromium-webview/prebuilt/arm64/webview.apk 替换为最新版本。
同样在 frameworks/base/core/res/res/values/config.xml 中，我将 config_webViewPackageName 的值从 com.android.webview 更改为 com.google.android.webview。
但是当我尝试启动一些使用 webview 的应用程序（例如标准 android 浏览器）时，我得到了这样的错误：

有人遇到过这样的问题吗？
最后我们发现问题是因为webmusic.apk没有使用系统签名。这就是它没有正确安装的原因。
问题 How to sign Android app with system signature? 中的步骤解决了问题。
