Question

So basically the code works fine until i hit the line i commented “//THIS DOESNT WORK!!!”. then nothing is entered into the database. Anyone know why i can enter them fine for the “StringCategory_Table” but not the other ones?

public class SetupOfSQLite{

Answer 1

I think your contValues variable has stale column information that is not meaningful for the restaurant tables. Try the following:

contValues.clear();
contValues.put(COLUMN_RESTAURANT, "Olive Guarden");
