Hi today i just tested html5 game exported from C2, i got the code for mozilla android https://github.com/mozilla/soup which i imported in eclips and replaced index.html and content from www folder in eclips.
I found that app provides best performance than chrome <img src="{SMILIES_PATH}/icon_e_smile.gif" alt=":)" title="Smile"> needs to implement some functions for sound and some other impairments needed.
