I'm having issues with ActiveAndroid. When I create a UserModel, it doesn't appear to be saving. getId() is returning -1.

So I tried your code snippets in a brand new project unmodified and tried saving a UserModel and it is saving properly with incrementing ids. On first launch, ActiveAndroid generates the schema for the sqlite database. You may want to delete the app off the emulator clearing the database and allowing activeandroid to recreate the schema.

Since I used your code unchanged in my sample app, it's unlikely that there's a major problem but you should also use breakpoints to check on UserModel currentUser = new UserModel(user.getScreenName(), user.getProfileImageUrl()); and verify that both the screen name and profile image are also what you expect them to be.

@DiyahM Post back here if you can't get it working and we can chat about more possibilities.

@nesquena Thanks! That fixed it! I had to delete the app off the emulator.

Great! When in doubt, often restarting the emulator and/or uninstalling the app (or wiping the emulator data) will fix a lot of problems. In this case, important to remember that ActiveAndroid only creates the database (and the tables) if there is no database yet created. That means if you run the app, the schema is created and then if you add models or change model attributes, those won't be updated unless the database is wiped (i.e app is uninstalled). Check out https://github.com/pardom/ActiveAndroid/wiki/Schema-migrations for how you can change the schema in situations where wiping the existing database isn't an option.
