Okay let's break it down. You want to make something that will let you take notes. Fair enough. You need the kind of storage that will make retrieval and insertion easier.

Let's start with a single text file that you store somewhere (internal or external). If you use this approach, inserting and deleting data becomes difficult because any changes will require you to make changes to the actual text. Not to mention, you will need to format your notes in a way so that you can differentiate one note from another.

Okay, so will using multiple text files solve this? In a way, yes, but you can go for a better approach using SQLite.

SQLiteDatabase has methods to create, delete, execute SQL commands, and perform other common database management tasks.

SQLite seems like the prime candidate for your storage because it makes CRUD (Create, Read, Update, Delete) easier. Instead of trying to modify the code, start from scratch.
