Upgrading from ArcGIS Android API v1.1 to v2.0

If you got a ArcGIS Android Project using ArcGIS API v1.1 and switch to v2.0, you will have a runtime exception when you do a pan action in the map view.

   FATAL EXCEPTION: main
   java.lang.UnsatisfiedLinkError: nativeSetAnimating
   com.esri.android.map.MapSurface.nativeSetAnimating(Native Method)
   ...

To solve this problem, you need to:

1. Create a new ArcGIS Android project using v2.0
2. Copy the files "libs/armeabi/libGLMapCore.so" and "libs/armeabi-v7a/libGLMapCore.so" back to your original v1.0 project directory

Very stupid right? But choose to use this product is stupid enough.
