This is an Android application that deals with storage or "data persistence". The app is suitable for any shelter house to store the data of pets such as name, breed, gender and weight of the pet. The app uses a SQLite Database to store the data. The data is stored locally on the users phone. This app uses many other concepts such as building a ContentProvider and using a CursorAdapter and CursorLoader to automatically load the data.
