how to insert rows into sqllite only once?

I have a table called language with Id, Name and flag etc. This table should be inserted rows only once and later will be static. Question is first of all,
- does it make sense or better to have it on sqllite or should I hardcode it or some other file? This regards to performance and storage usage.
- If it is sqllite, how can I just insert those values without running my app? or should i insert it onstart ?
