其实更准确的说法是:
每个基于 WebKit 的浏览器都会在http://m.allrecipes.com/上崩溃,但仅限于三星 Continuum SCH-i400手机。
我正在尝试实现一个基于 WebView 的浏览器,主要用于学习目的(市场上的浏览器太多了,为什么要添加一个?),我对我能以多快的速度提出一个基本的工作浏览器印象深刻。我在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,除了 m.allrecipes.com
.
每当我尝试加载该网页时,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此Samsung Continuum
手机上的行为方式,访问时m.allrecipes.com
:
结果非常有趣:Dolphin、Opera、iBrowser 等都没有任何问题。
但是Free Private Browser、Voice Browser和Easy Browserm.allrecipes.com
在使用相同的堆栈跟踪访问时都会立即崩溃。
因此,如果您可以将手放在一个Samsung Continuum SCH-i400
单元上,这个问题很容易重现。
我知道解决这个问题的最快和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,因为它可能会在使用 时指出潜在的问题WebKit
,也可能在其他手机上。
所以我的问题基本上是:
- 有什么
m.allrecipes.com
特别之处会触发这个WebKit+Continuum
错误? - 有什么
Samsung Continuum SCH-i400
特别之处以至于它只在这个网站上并且只在基于 WebKit 的浏览器上失败? - WebKit 中的东西太特别了,它不喜欢
Continuum+allrecipes.com
. - 是否有其他网站会触发此行为?
