I purchased this after reading your FAQ & Comments.
To use the plugin, I insert the "CordovaButtons" object to the layout and add a "CordovaButtons - On Back button" event to the event sheet with an action.
Then I export the project as HTML5 & test the output with the Android device.
As soon as I press device's back button, the browser's page goes back without any action.
Tell me what should I do to solve the problem.
