Colludium - Thanks for the feedback, and you are right! I am still very much confused about NodeWebkit being a wrapper, or whatever part it actually plays in construct. But I did use it as part of my code together with AsJSON and I was able to save my array to a text file and was able to load it during start up of the game. I am now able to continue playing my game from where I left it. But this does not solve my original problem of saving the game on android phone.
The code works when I "preview" the game on my PC but when I exported the game on my android, it won't save. Maybe this is what you meant by the "Nodewebkit is a wrapper for Windows/OSX/Linux?!?
While not giving up hope, I am thinking that may be I just did not specify the right "path" for an android phone. I hope someone can share some of their ideas on how to save games on android phone.
PS. I used Intel XDK to export my phone to android. Except for the saving part, the game works fine on my android phone.
