Android 11 WebView无法加载libwebviewchromium.so

概述

       Android WebView 是 Google 提供的一个预安装系统组件，用以支持 Android 应用显示网页内容。

       如果您希望在客户端应用中提供 Web 应用（或只是网页），则可以使用 WebView 执行该操作。WebView 类是 Android 的 View 类的扩展，可让您将网页显示为 Activity 布局的一部分。它不会包含功能全面的网络浏览器的任何功能，例如导航控件或地址栏。WebView 默认只显示网页。

使用 WebView 非常有用的一种常见情形是，您希望在应用中提供可能需要更新的信息，例如最终用户协议或用户指南。在 Android 应用中，您可以创建一个包含 WebView 的 Activity，然后使用它来显示在线托管的文档。

另一种 WebView 可能会有所帮助的情形是，如果您的应用向用户提供始终需要互联网连接才能检索数据的数据（例如电子邮件）。在这种情况下，您可能会发现相比于执行网络请求，然后解析数据并在 Android 布局中呈现数据，在 Android 应用中编译 WebView 以显示包含所有用户数据的网页更加轻松。您可以改为设计一个专为 Android 设备定制的网页，然后在加载该网页的 Android 应用中实现 WebView。

    在测试RK3566 Android 11功能的时候，碰到一个奇怪的问题: 第三方浏览器APP调用系统WebView出错了。测试中用的是Via浏览器，问题表现威：白屏，UI卡死操作一会出现ANR。

基本与第三方APP没什么关系, webview的lib库是在开机就加载的.

bionic/linker/linker.cpp 根据经验，先到linker打打LOG

error 3 表明，这两个条件都有问题：entry.method != kCompressStored || (entry.offset % PAGE_SIZE) != 0

解决

   非逻辑问题，怀疑webview文件的问题，尝试替换掉webview试试，从另一套代码中拷贝出编译好的webview， PUSH到主板中，问题神奇地消失了。

最终发现是改了编译配置导致生成的webview.apk文件不一致导致(APK的优化对齐相关)。

在修正了文件问题后，对应目录的RELRO存在相应的文件。
