我看到下面的错误在开发周期中了几次，现在我刚刚收到错误报告。我不知道是什么导致了这一点。阅读关于这个问题在这个网站类似的问题后，我双重检查我的Andr​​oidManifest，一切看起来没什么问题。什么任何想法可能可能会导致这个异常？

另外要注意的事情是，我使用的是Android的支持-V4-GOOGLEMAPS在LIB的 https://github.com/petedoyle/android-support-v4-googlemaps ，让我来嵌入片段的图形页面（与ActionBarSherlock LIB一起）。这个例外似乎是一个依赖的问题，我不知道，如果是涉及到我如何使用上面提到的库。

解决方案

它看起来像我已经不使用了android支持-V4-GOOGLEMAPS LIB固定的问题。我改变了我的应用程序使用地图的ImageView的一个片段，然后一个普通的老MapActivity一旦用户点击地图图像。因为这样做，我还没有发现任何RuntimeExceptions。

I've seen the following error a few times during the development cycle and now I just received an error report. I have no idea what's causing this. After reading similar questions on this site regarding this issue, I double checked my AndroidManifest and everything looks fine to me. Any ideas on what could possibly be causing this exception?

Another thing to note is that I'm using the android-support-v4-googlemaps lib found at https://github.com/petedoyle/android-support-v4-googlemaps which allows me to embed a MapView in a Fragment (along with the ActionBarSherlock lib). This exception seems like a dependency issue and I'm not sure if it's related to how I'm using the above mentioned libs.

It looks like I've fixed the issue by not using the android-support-v4-googlemaps lib. I changed my app to use an ImageView of Map in a Fragment and then a plain old MapActivity once the user clicks on the Map image. Since doing this I haven't noticed any RuntimeExceptions.
