can anyone help me

Answer 1

Change;

public long insert(String name) {
        this.insertStmt.bindString(1, name);
        return this.insertStmt.executeInsert();
}

To:

public long insert(String name) {
    ContentValues args = new ContentValues();
    args.put("name", name);
    return db.insert(TABLE_NAME, null, args);
}
