打开 PDF 时，在 Lollipop 上膨胀类 android.webkit.WebView 时出错 [英] Error inflating class android.webkit.WebView Crash on Lollipop when opening PDF

问题描述

在我的应用程序中，我在自动测试期间遇到了错误.我试图从 WebView 中的 URL 显示 PDF，这会导致在运行 Android 5 Lollipop 的设备上发生此崩溃.完整的崩溃日志引用了未找到的 WebView 中的 String 资源，到目前为止我都无法从中获得太多.

In my app I encountered said Error during auto-tests. I'm attempting to show a PDF from an URL in a WebView which causes this crash on devices running Android 5 Lollipop. The full crash log references a String resource in WebView not being found, which I couldn't really gain much from either so far.

我知道这是一个已知问题，但到目前为止还没有解决方案修复崩溃，只能阻止 Android 5 设备达到该状态并尝试显示 pdf.

I am aware this is a known problem, but so far no solution has fixed the crash, only prevented Android 5 devices from reaching that state and attempting to show the pdf.
