Question

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

09-12 23:27:32.855: ERROR/AndroidRuntime(19152): java.lang.NullPointerException

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.

Thanks in advance!

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
