Android: How can I share SQLite table with another phone with the same APP

view story

http://stackoverflow.com – I am thinking regarding the future options of my app and I am thinking of the idea of backing-up the data from the application's Database and also sharing that data with another phone, say via e-mail, messaging, Bluetooth, you name it, but basically saving it as a file and opening it from the other phone and having the same values on both phones. What would be the best approach for such an Android application? Would Content Providers accomplish exactly this or are they concerned with sharing data only between different Apps? Thanks! (HowTos)
