Hello! Thanks for trying to help.
I am aware that the C2 allow us to specify the version number. But mine is a different problem on 'versionCode' not 'version' on Google Play.
I manage to found the answer. This is a problem with phonegap not C2. Someone discussed about it under the phonegap
forum. It's useful if anyone would like to update their .apk in future.
Under the config file, specify it to something like this:
version = "2.0.0">
It's working fine for now. nicekiddy2012-04-19 06:27:52
