I am attempting to import a database into Android Studio. Right now, I have a database in my assets folder, and I'm displaying it into a listview. I'm getting a "File is encrypted or is not a database" error.
I'm not sure what database file types that Android Studio supports. I'm using SQL. I named my database helper class Ingredient Helper.
I would really appreciate any suggestions you could offer. Here's my logcat and java files.
Thank You!
