OK - I managed to get the social share function working with PhoneGap - so users can send and share highscores etc via messages/twitter/facebook etc...
But I also want to be able to include a snapshot of the last highscore visual.
As the game moves so fast the user won't have time to save their own highscore screenshot, so it's automated to take a screenshot each time the current score is greater than the current highscore.
So then theoretically the snapshot is saved to include in the social share message - "&CanvasSnapshot&" :
However it's not working. When the social share button is pressed it looks like the phone tries to load an image but the image placement is empty and the message fails to send.
Any idea what I need to do to make this work?
