Android WebView测试与更新——rk3568

概要：本文介绍了在rk3568平台上进行Android WebView兼容性测试的方法，探讨了不同WebView实现的差异，并提供了WebView的下载方式及预装配置方法，旨在帮助开发者解决特定网页在不同WebView版本下的显示兼容性问题。

1. 什么是Android WebView

Android WebView 是一个系统组件，允许 Android 应用在自身内部显示网页内容。它本质上是一个嵌入在应用中的浏览器引擎，开发者可以利用它加载网页而无需跳转到外部浏览器。

---

2. 测试目的

主要测试 WebView 的兼容性。

• 某些网页只能在特定版本的 WebView 应用中正常显示。
• 通过测试识别并选择兼容性良好的 WebView 版本，以提高用户体验和功能的稳定性。

---

3. 测试方法

• 并非直接使用内测浏览器进行测试。
• 采用 APK 调用 WebView 实现测试。
• 推荐使用 WebView Test 软件进行测试，支持输入指定网址进行加载验证。

---

4. 不同的 WebView 区别

• AOSP原生WebView（com.android.webview）
  • rk3568 原生带有该版本，但版本较低，可能存在兼容问题。
• 腾讯X5内核
  • 国内常用，兼容性较好，适合某些特定场景。
• Google Play版本WebView（com.google.android.webview）
  • 可从 Google Play 下载较新版本，具有更好的兼容性与性能。

---

5. 下载地址

• WebView（Google Play 版本）——实测该版本缺少一个库com.google.android.trichromelibrary
• WebView Test 测试工具
• APK 提取工具

笔者有一个完整的webview包

6. rk3568预装方式

6.1 预装路径

vendor/rockchip/common/apps/

6.2 修改说明

1. 取消原有预置 WebView 的安装
   • 删除以下文件：

     external/chromium-webview/Android.mk
     

2. 修改系统默认 WebView 包名配置
   • 编辑以下文件：

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