I am going with the assumption that this is a local Android app, which you would be using as an inventory manager, meaning you would use it to add/remove items and other inventory related things. If so, I could very much help you, because I am an experienced Java programmer, with real good experience in database management(which seems to be crucial for the project), and since the platform is Android, I would approach the project by designing the database and implementing it in Sqlite on Android(maybe using some ORM framework if necessary). I hope that is enough information for the beginning. I think that the best next step is for you to send me the details of your project and requirements, so that I can review it and tell you if I am up for the whole task. Cheers!
