How to turn an MSSQL database to SQLite database for Android

I have an MSSQL database. I want to use it in an Android app. I apparently need to turn it to an SQLite database. How I can do that? All I can do in SQL is getting a .bak file which seems useless for my purpose so far. Can you tell me how I should get the database from Microsoft SQL Management Console and how I should add to my Android project? Thanks.
