Answer 1

I think you modified the database scheme after the first install of the app.

You have to write an update script from the old version of the Database to the new version. (ALTER TABLE tablename ADD COLUMN ....)

Or delete and install the app again.

Answer 2

During update your column name is not match with table actual column name. Try below:

String sql = "UPDATE PRINCIPAL SET selectname=?, eventname=?, eventorg=?, eventdays=?, eventstart=?, image=? WHERE id=? ";

There are two mismatch in column between create and update sql

name should be selectname

eventorganization should be eventorg

Also your table name PRINCIPALS not match with PRINCIPAL .
