I’m frustrated

Offline Mobile App with Database

I got an export database from Mysql in Json format with around 800 entries. each data set got 8 colons. The app to built is about to show/display the detail about entry via a search box input. The requierement is that it must work offline.

I've read about echo service but donot get how to work with. Also want to know to prepopulate the database for the first load of the app.

Plz help
