I'm trying to run cocos2dx sample project (the one created with create-android-project script) on Android device or emulator.

However the application crashes on start with the following errors:

Any idea what is going wrong? The build_native.sh script seems to work fine, I resolved some Eclipse errors by changing compiler complience level to 1.6 and adding libcocos2dx.jar to my project's build path.

Cheers, Marcin

You must remember to instantiate the activity in AndroidManifest.xml

EDIT : Check your project properties and make sure that all jars or libraries of crocos2d are checked for order and export.

I am having the same problem. I have everything configured. No jar file is added to build path in my case because I have a cocos2dx library added to the project which contains libscocos2dx.jar

Although I have a so file which normally is not required to be added to the build path but I have added that as well just to check it works or not and unfortunately it didnt

Solution: RESTART YOUR IDE! Then remove project errors (probably connected with libcocos2dx that it can't find).
