Good evening, I'm learning about CRUD in my mobile programming course, we're programming in a SQLite database, as the project is not yet ready for the teacher's own reasons, to check if the Database works, we're putting the data in the first screen that appears in the app (in the case the presentation screen) to load and so the data is already recorded, however as the image shows, is giving error in the obj and I can not understand why. Only from error if it is obj, anything else written not from error. I have already compared the project to the teacher's project, I did not find the problem, what can it be?
