SQL Lite Prepopulating

We had an app which was getting data from online API, to render data in the UI. We are planning to make it into a local SQLLite App. What is the best way to achieve this. More about the App: Its a rate chart of some parts of an Automobile. There are about 5000 parts..

Requirements: 1. On opening the app, check if table exists, else create it and insert the data from the online APIs. 2. Fetch Data from the SQL Lite instead of reading from the API. 3. Auto Sync or Manual Sync of data from the mobile.

Kindly enlighten me what would be the best approach to handle this.
