Android 无法捕获的 NullPointerException

Android uncatchable NullPointerException(Android 无法捕获的 NullPointerException)

问题描述

我的应用中有一个非常烦人的 NPE，但找不到解决方案.首先是堆栈跟踪:

I have a pretty annoying NPE in my app and can't find a solution. First the stack trace:

当我快速切换方向时会发生 NPE.有人有同样的经历吗?有解决办法吗?另外我需要提一下，我使用 Admob.我不知道这个 NPE 还会出现在 WebView 的什么地方.

The NPE occures when I switch the orientation very fast. Does somebody experience tha same? Is there a solution? Also I need to mention, that I use Admob. I don't know where else this NPE could occure in a WebView.

提前致谢！

推荐答案

我回答了我自己的问题:通过正确的关键字，我终于在 Google 找到了一些不错的结果.这绝对是一个 Admob 问题.如果你有兴趣，可以看看这个帖子

I answer my own question: With the right keywords I've finally found some good hits at Google. That is definitively an Admob issue. If your are interested in, take a look at this thread
