Using databases on Android development

I have just started on Android development, and I'm having lots of doubts on the implementation of Databases in apps. I need to use a database that will already be filled with information and another database that will be updated upon information provided by the application. Through my searches I wasn't avble to find a tutorial that would help me to implement a database that is filled with information, and that is the first of my doubts. The second one is the following: how do I access information based on the row they are in, and is there any way to implement bubble sorting in a database.
