Publishing apps has both similarities and differences in Android and iOS. They both require the same type of information to be entered for the app that is to be sold. However, the exact procedure is different. Prior to publication of an app, thorough testing is required. An app that crashes frequently or does not do what it says it does will not pass the Apple review process. An Android app that has the same problems may be allowed to be published, but it will get bad reviews and may be eventually removed by Google. After you have published apps it is imperative that you keep up with platform changes. New versions of the OS can create problems for apps that currently run perfectly.
