Hi All,
I have 3 different applications: 1,2,3.
Application-1 creates its own database.
Can the other applications: Application-2, Application-3 access that database (with was created by Application-1) if they know database name ?
Can some way to share the single database with different independent applications ?

I don't know if you can just access an apps database (read: I don't know if it's possible to make a world readable/writable database). But the solution Android gives you, is using ContentProviders. Those are the things which are designed to handle data access from other tasks.

Thanks MrSnowflake for prompt. I'll try to implement it for my case
