I have an android app published in Playstore. I need to add some columns to the existing table. When I drop and recreate the table, all data will be lost.

Is there any way to alter the database keeping existing data.

What I have tried:

ALTER TABLE ADD COLUMN IF NOT EXISTS doesn't seem to be helping me.
