SQLite Database in Android Studio ||Writing Data and Displaying Result in Recycle View||2021

[ultimat.]

hello, I'm not looking for one of my tutorials. tutorials on external SQLite with source code and lots of explanations to fully understand. I would like a tutorial to be able to add an image, delete or modify an image in an external db.sqlite database. after a second tutorial. this one would display 2 or 3 categories which is in a db.sqlite categories table and which would open sub categories which belong to 2 and 3 which will also be found on an external db.sqlite base and a one click afterwards to display sub categories. here are just 2 tutorials that allow me to move forward thank you in advance.
