Error in testing oF 0.8.1 for Android

I downloaded oF 0.8.1 for Android from the main repo. I try to test the assimp model loader example on a Samsung S4 device. I get the below error. Does any one have a clue about how to fix it?

I find out that there are two directories created (both 2 are empty):
“/sdcard/Android/data/cc.openframeworks.androidAssimpExample”
“/sdcard/Android/data/cc.openframeworks.androidAssimpExample/files”

and there is not a “/data/data/cc.openframeworks.androidAssimpExample” directory.

Is the error related to this issue? Anyway, how to fix it?
