其实更准确的说法是:
Every WebKit-based browser crashes on http://m.allrecipes.com/ but only in a Samsung Continuum SCH-i400 phone.
我正在尝试实现一个基于 WebView 的浏览器，主要用于学习目的(市场上有太多的浏览器，为什么要添加一个？)，我对我能多快地想出一个基本的工作浏览器印象深刻.我在我的 Samsung Continuum 手机上的许多网站上对其进行了测试，它们都运行良好， m.allrecipes.com 除外。
每当我尝试加载该网页时，我都会收到以下 NullPointerException:
E/AndroidRuntime(3147): FATAL EXCEPTION: http10
E/AndroidRuntime(3147): java.lang.NullPointerException
E/AndroidRuntime(3147): at android.net.http.CertificateChainValidator.doHandshakeAndValidateServerCertificates(CertificateChainValidator.java:194)
E/AndroidRuntime(3147): at android.net.http.HttpsConnection.openConnection(HttpsConnection.java:308)
E/AndroidRuntime(3147): at android.net.http.Connection.openHttpConnection(Connection.java:358)
E/AndroidRuntime(3147): at android.net.http.Connection.processRequests(Connection.java:219)
E/AndroidRuntime(3147): at android.net.http.ConnectionThread.run(ConnectionThread.java:113)
无法在我的代码中找到对此的解释，我试图查看其他浏览器在这个 Samsung Continuum 手机上访问 m.allrecipes.com 时的行为:
调查结果非常有趣:Dolphin、Opera、iBrowser 和其他浏览器都没有问题。
但是Free Private Browser , Voice Browser和 Easy Browser使用完全相同的堆栈跟踪访问m.allrecipes.com 时，所有程序都立即崩溃。
因此，如果您能拿到 Samsung Continuum SCH-i400 设备，这个问题很容易重现。
我知道解决此问题最快捷、最简单的方法是使用不同的浏览器或摆脱我的手机。但我希望了解问题的根源，因为它可能指出使用 WebKit 时的潜在问题，可能在其他手机上也是如此。
所以我的问题基本上是:
m.allrecipes.com中有什么特别之处会触发此WebKit+Continuum错误？Samsung Continuum SCH-i400有什么特别之处，以至于它只在这个网站上失败，并且只在基于 WebKit 的浏览器上失败？- WebKit 中的特别之处在于它不喜欢
Continuum+allrecipes.com的组合。 - 是否有其他网站会触发此行为？

最佳答案
顺便说一句，我认为您的 Continuum 仍在运行 Android 2.1。
What in m.allrecipes.com is so special that it triggers this WebKit+Continuum bug?
在 Android 2.1 模拟器中，我收到“此证书不是来自受信任的机构”对话框，但它没有崩溃。 Android 2.1 可能不支持 StartCom 的根证书(如果我没看错的话，就是有问题的权威)。
According to this issue , StartCom 的根证书是在 Android 2.2 中添加的，在 4.0.3 模拟器中快速测试不会引发错误对话框。
What in Samsung Continuum SCH-i400 is so special that it fails only on this website and only with a WebKit-based browser?
三星可能在 android.net 包中调整了一些东西并破坏了它，也许特别与粗略的 SSL 证书相关联。任何基于 WebView 的浏览器都将通过相同的代码路径运行；每个拥有自己的 HTML 渲染器的人可能不会，如果他们自己处理 SSL 证书等。
What in WebKit is so special that it doesn't like the combination of Continuum+allrecipes.com.
技术上没什么，基于堆栈跟踪。您会注意到其中没有任何特定于 WebKit 的内容。这最多是一个 WebKit-on-Android 问题。而且，如上所述，它可能更适合您的三星。
Are there additional websites that trigger this behavior?
也许可以从较小的证书颁发机构找到其他证书。
关于android - 每个基于 WebKit 的浏览器都会使使用 Omniture 的网站崩溃。为什么？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/11353365/
