Add your graph and labels file to your Asset-folder. I don't remember but I think you can name them whatever you want as long as you use the right extension names (i.e *.lite and *.txt). Then when you initialize the lib, you pass on the names of the files:
ten.Initialize("", 224, "yourgraph.lite", "yourlabels.txt")
If you use my demo-app and use different names, make sure to change the code which verifies if a file exists in the asset-folder.
At this point, you should be able to remove any previous files (if present)
