Smile Font Android App Flasher with Database (HELP DEVELOP)

Hi, I want to start a project of an AndroidApp that could flash a font package or instead of this just change the font from the filesystem using root. Wanna code font-backups, own-library to keep the downloaded fonts or even to add more by yourself, and a database where the users can download the fonts using a little preview system on each fontpack.

Need somebody who helps me coding it. It could be a really great project.
