}

Please help. Thanks

Your insert SQL is totally wrong. Try to add one entry and do it again if the first one worked.

String sql = "INSERT INTO pepak (name) VALUES (\"SampleText\");";
database.execSQL(sql);

If that works, you can simply create a new insert SQL statement and finally you will have something like that:

String sql = "INSERT INTO pepak (name) VALUES (\"SampleText\");";
database.execSQL(sql);
sql = "INSERT INTO category (name) VALUES (\"CategoryText\");";
database.execSQL(sql);

If you insert more than 20, you should think about a custom transaction handling to speed the inserts up.

// pseudocode
database.startTransaction();
doAllInserts(); // method/loop for all inserts - depending on your needs
database.setTransactionSuccessfull();
database.commit();
