which is best option to publish android app with local database?

I am developing an app in which i would need a local database.
So as per my knowledge there are two ways to do it:
First is to add pre filled database file in assets folder & make copy of
local database from it the very first time app is started.
Second is using script to download it from Server for first time of app use?
First way have been pretty well answered by this guy Using your own sqlite
database in android application
Can someone help how can i go with second way of download data from Server?
Should i use JSON/XML for getting that data from my Server?
Or should i go with first option since my app has only around 150 to 200
rows in the db file?
