Problem running Tutorial Chapter 3 - How to Move a sprite

Hi all, I’m trying to learn cocos2d-x to program multi-platform games.

I’m doing the tutorial to learn cocos2d-x on android. I build and run the second tutorial chapter without a problem, but with the third I have an error while running the app in the phone.

Compile C++ (with build_native.sh) works ok, and build and install the .apk too, but when it tries to start, is closed by the error:

Some idea about what can be?

Thanks for the help!
Pere.
