Downloading data/content into Sqlite database

I want users to be able to get additional content from my website which means I will insert the downloaded data into the device's SQLite. I am wondering if I am approaching this the right way..

My current approach is to create a 开发者_运维知识库REST web service which returns data in JSON format, parse the JSON and insert it row by row into the Sqlite db on the android device.

Is this the right approach? Will it be too slow if there are many table rows to be inserted at one time? Or is there a way to download another SQlite db and merge it with the local one?

I welcome any suggestion, thank you in advance for your answer.

I works, but you absolutely need to paginate : set a limit to the number of element sent by your rest service.

Another approach would be to download the complete sqlite database file at once, but that requires some tweaks. see http://www.reigndesign.com/blog/using-your-own-sqlite-database-in-android-applications/ (it is about embeding the database from the assets, but the preparation of the database is the same.)

A last point: large amount of insert, as well as downloading data from a server, must to be done in a separate thread or asynctask, from a service (not an activity that can be interrupted), or even better from a SynchronizationAdapter, which is called by the system itself.
