    针对部分Android 8.0使用webview加载html崩溃的问题,不少地方指出了是android system webview_V58的系统bug所导致,解决方案有一点就是安新的webview的新版本~

    在做一款系统应用的时候用到WebView这个控件.但是在编译的时候直接就出错了.抛出For security reasons, WebView is not allowed in privileged processes

  • Android 7.1 WebView 实现方式选择

    千次阅读 2019-03-29 14:57:44
    平台 ...1.在Pixel上, 可以显示两个选项: Android System WebView 和 Chrome 尝试把Chorme 禁用后, 选项中, 仅剩下Android System WebView. 2.尝试在RK3288主板上安装Chrome, 并增加相应配置 <...

    Chrome方法已废弃

    后续测试, Chrome已经无法使用此方法, 也找不到当初对应测试的版本
    Google Chrome app is no longer the WebView provider in Android 10

    后续采用Google WebView, 改法参照下文

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

    平台

    RK3288 + Android 7.1
    

    说明

    选项位置: 设置 > 开发者选项 > WebView实现
    

    1.在Pixel上, 可以显示两个选项: Android System WebView 和 Chrome
    尝试把Chorme 禁用后, 选项中, 仅剩下Android System WebView.

    2.尝试在RK3288主板上安装Chrome, 并增加相应配置

    	<webviewprovider description="Chrome WebView X" packageName="com.android.chrome" availableByDefault="true">
        </webviewprovider>
    

    编译烧录后, 可以看到, 新增了Chrome WebView X, 测试选择不同的实现方法, 均可正常使用.

    为确认装入Chrome后可以生效, 已删除源码自带/system/app/webview

    在为客户做安卓系统定制开发时发现系统自带的浏览器会有一些小问题比如下拉框的选项点不到,滚动时卡顿。浏览器在apk中内置了webview,一般非浏览器app中使用的webview可以使用第三方的,也可以使用sdk自带的,如果使用sdk中的webview版本就会调用android system webview,adb环境下可以通过
    adb shell am start -a android.intent.action.VIEW -d  https://liulanmi.com/labs/core.html  来查看webview版本。

    android4.4以后,webview独立出了成为了一个系统apk,在/system/app/下,包名是com.android.webview,然后配置文件中包含了系统默认webview的包名,修改该默认包名,就可以替换System webview
    修改:
    从google商店下载最新的google webview替换系统里面预装的System webview
    apk路径:external\chromium-webview\prebuilt
    根据芯片架构替换不同目录下的apk
    然后修改/frameworks/base下的配置
