Update my local sqlite DB with a distant DB server

Hi, i make an Unity application that has a local sqlite BD and some interaction ( exp: select ,delete ,...) . I export this application to android platform. This export was a success and it create me my DB and I can make my interaction with the BD. My question is that: if I put my DB to a distant server and make some updates( exp : add some entries, ...) how can my local DB be updated ?? Should I implement some native android code to update this BD ?? Or should I make some code in the unity source script to update my local DB if there is a difference?

Thanks in advance :)
