Application Manager is an Open Source application that allows you to seamlessly edit application's preferences.
This application requires a rooted phone! Without root access, it can not do anything.
Android provides several options for developers to save application data. The most frequent solution is the Shared Preferences framework. It's a simple way to store private primitive data in key-value pairs. Unfortunately, this method is not very secure ... It consists in a simple XML file stored in the private folder, specific to the app. But in the case of a rooted device, theses files can be read, edited and even deleted.
Preferences Manager allows you to edit these preferences in a simple and easy way. You can for instance increase your highscores, modify your progression, or just debug your application preferences.
