Found long, needs Boolean (Inserting into SQLite [Android])

For some reason, my return statement returns a long as opposed to a boolean, can't progress to test anything unless this is resolved. I have no idea why it is even doing this. Tried everything within the scope of my knowledge, hence why I am here.

Looked at some other people's examples before I posted and they seemed to use the same return statement as I have, with no issue.

public boolean updateDatabase(String Name) {
    SQLiteDatabase db = this.getWritableDatabase();
    ContentValues args = new ContentValues();
    args.put(COL_1, Name);
    return db.insert(TABLE_NAME, null, args);
    db.close();
}
