ndk version 9

Try r9d instead of r9

I got it working already. thanks, but I have another problem Im trying to use the given example error at this line MuffinRushAssets *ret = new MuffinRushAssets();

I tried https://github.com/soomla/cocos2dx-store-example/blob/master/Classes/MuffinRushAssets.cpp
but there Is an error on line MuffinRushAssets *ret = new MuffinRushAssets(); says “allocating an object of abstract class type ‘MuffinRushAssets’”

Post on the soomla forums as they can be helpful.
