VasSonic is a lightweight and high-performance Hybrid framework developed by tencent VAS team, which is intended to speed up the first screen of websites working on Android and iOS platform.

Hello,

First of all, thank you for such an amazing library for web services. I would like to know how to change the default language of VasSonic WebViewClient (or WebSetting..). All contents in the website that loaded from VasSonic are rendered as Chinese. I have tried to dig into the wiki but haven't found a way yet.

Please let me know if there is a way or workaround for this. Thanks in advance!

https://github.com/Tencent/VasSonic/issues/239 承接之前的问题哈（不知道为啥被关闭了）

@marlonlu 但是这边都是拦截demo url来进行试验的。没有由服务端结算返回数据块（内容是直接返回整个页面），这边也开了local server模式。应该会由客户端计算并执行局部刷新吧？ 这边拦截后 ，无论是demo url 还是自己的 test url（返回的内容相同） 都是Cache-Control: max-age=0

但是测试的结果（上一个回复https://github.com/Tencent/VasSonic/issues/239 ）对比很奇怪，能解答下疑问吗？

可以的话可否通过别的方式聊下？qq或者微信

What steps will reproduce the problem? 该问题的重现步骤是什么？ 1.打开页面的时候出现 sonicSession为空 几率性事件，多为第一次点击 if (null != sonicSession) { sonicSession.bindClient(sonicSessionClient = new SonicSessionClientImpl()); } else { // this only happen when a same sonic session is already running, // u can comment following codes to feedback as a default mode. // throw new UnknownError("create session fail!"); Toast.makeText(this, "create sonic session fail!", Toast.LENGTH_LONG).show(); } 2:我在这里的操作是出现初始化异常的时候将错误信息抛出，导致程序奔溃

What is the expected output? What do you see instead? 你期待的结果是什么？实际看到的又是什么？ 什么情况会造成这种初始化异常，当让我想拦截这种异常，使程序稳定

What version of the product are you using? On what operating system? 你正在使用产品的哪个版本？在什么操作系统上？ 使用的是2.0版本，在1.0版本好像没出现过，android系统

我是移动端的，最近打算优化Webview的加载速度，然后下了demo体验了一把。demo中的加载速度和离线加载，确实速度快了不少。如果将demo中的url改成我自己项目的url，速度还是一样的。那么问题来了，提升加载速度是服务端、客户端、前段一起优化的结果？如果只是客户端做优化，服务端不参与，能达到demo中的效果吗？

What steps will reproduce the problem? 该问题的重现步骤是什么？ 1.url有效，但是加载不出来，直接显示一个空白页面 2. 3.

What is the expected output? What do you see instead? 你期待的结果是什么？实际看到的又是什么？ 期待看见加载页面，实际看见一个空白页面

What version of the product are you using? On what operating system? 你正在使用产品的哪个版本？在什么操作系统上？ compile 'com.tencent.sonic:sdk:2.0.0' android

引入Sonic.framework，打包的时候报错 Sonic.framework/Sonic(SonicUitil.o)' was built without full bitcode. All object files and libraries for bitcode must be generated from Xcode Archive or Install build for architecture arm64

What steps will reproduce the problem? 该问题的重现步骤是什么？

1. 创建得时候总是说url不合法
2. sonicSession = SonicEngine.getInstance().createSession(infoUrl, sessionConfigBuilder.build());

VasSonic 方案没有兼容 Weak Etag。 当使用 nginx 开启 gzip 特性时，snoic_differ 写入的 etag 会被 nginx 修改为 Weak Etag。 在 WEB 服务不自己处理 gzip，而是依赖前端负载均衡或者 CDN 服务提供 gzip 时，VasSonic 将难以集成。 而很多WEB项目是使用 nginx 做前端负载均衡处理 gzip 的，在使用 VasSonic 时困难较大。

考虑可行的方法：

1. 完全不使用 gzip 进行 sonic 请求
2. 需要集成的 WEB 服务修改为自己处理 gzip
3. 避开 Etag 响应头使用自定义响应头
4. 更新 VasSonic 使兼容 Weak Etag

想请问开源项目参与者们的意见。

PHP Fatal error: Call to undefined function getallheaders() getallheaders这个函数在非Apache服务器下，如nginx或FastCGI模式下可能不存在，可以考虑$_SERVER['HTTP_XXX']方式获取request header。

We use - replaceOccurrencesOfString:withString:options:range: to replace tag. But it's not efficient and much time cost. It needs to scan whole file to replace.

I run a performance test to compare the new(my PR) and old(framework currently implementation), split the framework demo main.html 1000 times, results are below:

Used main.html:

Used main.html but has 10 data tag:

Used main.html but has 20 data tag:

Used main.html but has 20 data tag, and double file size:

Conclusion: Along with increasing of data tag or file size, the old method's cost is increasing much higher. For the last test, new split method is at least 6ms faster than old way.

What steps will reproduce the problem? JFrog, the company that maintains the JCenter artifact repository used by many Android projects, made JCenter a read-only repository on March 31st, 2021. According to the announcement, JCenter will allow downloads of existing artifacts indefinitely.

Developers who publish artifacts on JCenter should migrate their packages to a new host, such as Maven Central.

Developers who use dependencies from JCenter will need to find the new location of updated versions of those dependencies.

What is the expected output? What do you see instead? Migrate to another repository (JitPack / Maven Central / etc)

What version of the product are you using? On what operating system? Version 3.1.0 (Android)
