Question

Insert the data to the current application database from the another application database. Any example?

Answer 1

I suggest two ways that you can achieve this.

1. You can save the database in the external storage and access it from there. See here.
2. You can save the database in the internal application storage and access it with content providers.

EDIT I suggest the second way using content providers since it is the recommended way and it is also more safe. If you save your database to your external storage the user can access and modify it and that can cause troubles.
