Preference Manager is a free development application for mobile from developer Firefly. It is a programming utility that helps programmers open and edit XML files, and make changes on a per-app basis as they want. It boasts a clean and simple user interface to facilitate the experience and make it easier and more intuitive.

App preference management

Android commonly lets developers save application data through the SharedPreference framework and by modifying XML files available for every app. In comes the Preference Manager app, which is essentially a front-end GUI to make the whole process a bit more visually pleasant experience, with a clean interface to add, edit, or even remove entries.

What's more, you can create backups before making any changes, so you can restore an app to its default state in case something doesn't work properly. The only thing you need to be aware of before proceeding is that your device has to be rooted as this app needs root access in order to work and apply the changes properly.

Handy and intuitive

To sum up, the Preference Manager app is pretty much a must-have for any Android developer looking to create apps for the popular mobile OS. It makes it easier to edit, delete, or add entries through an intuitive GUI instead of just opening up a text file. Just make sure your device is rooted, and you're ready to go. Recommended.
