SQLite or something else?

I am trying to decide on what data storage methods to implement. Here is the situation. Whatever method I ch开发者_开发技巧oose, it is going to be updated once week (can I update a SQLite db without putting out an update in the market?). The user cannot add or remove items from this ListActivity, they can only pick the ones they want. This data method should be able to remember the selected items during any given week. Let me know what method you would use and why. Thanks so much in advance.

A webservice would allow you to update the data whenever you want without having to push updates to the market. And updating your app in the market doesn't guarantee that users will apply the update. Ofcourse the downside here is that your users would need to be connected to the internet while using the app.

Moving your database to remote server will give you freedom to manipulate data without actual application being updated, thus no need to update on the market. If it is a matter of access to internet, you can still use this practice, just more work has to be done (adding Broadcasters that will listen to connectivity than update the local database with global one on your server, or something similar).

If you want to update the data on the device once a week, then you will need to use the local SQLite database and interact with a web service that provides the updates. You will not need to go through the market to do this. However, if you need to update the structure of the database (add, remove, or change columns or tables for example), then you will need to update your app on the market.

I highly recommend watching the Google IO 2010 talk Developing Android REST client applications. The speaker is the author original author of the Twitter app for Android, and talks about the design patterns and best practices that he uses.
