I have a PhoneGap App using jQuery Mobile. At a certain page, I cannot let the user go back to the last page he visited.
The pages order is like this:
jQuery Mobile uses the browser history for page to page navigation, so preventing the user from going back is not really possible in a browser. However, since you have a phonegap app, you can handle the back button directly. This question should help you: Override Android Backbutton behavior only works on the first page with PhoneGap
