im trying to create a ViewPager for my app. Im new to android developing so first im trying a sample to look how it works from [this](http://blog.stylingandroid.com/archives/537) site. 
When i try to run it in the emulator it force closes. I dont know why i get the error, i checked the code lot of times and there is no difference.

So as the code is the same as in the link above i only provide the logcat.

```

The com.viewpagerindicator is a libary project (on the link its com.jakewharton.android.viewpagerindicator, i know that, i just changed it to the original), there i changed nothing, only imported from the authors site.
So if anyone know what i did wrong please help. I can provide more information if this is not enough.
