  • Dimitrios Tosidis completed this course, spending 10 hours a week on it and found the course difficulty to be medium.

    It includes a SQLite course and implements asynchronous database connection, content providers through uri and other patterns. The project is challenging and is a first sample of an app that creates a database in the cell phone. A great course for a big theme.
  • Mike Urbinhio completed this course, spending 20 hours a week on it and found the course difficulty to be hard.

    Way to buggy and way to outdated. Sometimes huge configuration problems. It is not complete waste of time, still working example seams like way more simple then understending google ways of implementing elements. In most cases their not gonna be needed for beginners.
