Question

I received this error twice in the last three days on different devices. I do not use WebView at all in my app so I am a bit confused.

The only thing I can think of is AdMob but wouldn’t that show up in the stack trace?

Here is the stack trace:

java.lang.NullPointerException at
android.webkit.WebView.stopLoading(WebView.java:1842) at
c$a.run(Unknown Source) at
android.os.Handler.handleCallback(Handler.java:587) at

Update: In addition to the link Arhimed provided here is a link where an AdMob rep is discussing this as well

From what you said I am pretty sure this is an AdMob issue. The reason you don’t see any “AdMob” occurrencies in the log is that AdMob comes as an obfuscated library jar. So c$a.run(Unknown Source) is a log enrty produced by an obfuscated code.

UPDATE:

This IS really related to AdMob. There is a related SO question: Android uncatchable NullPointerException
