How to pass database objects between activities (Android)

Question

Is there any way to pass database object between activities. I have already tried the following ways for doing this.

1. Implementing interface.
2. Using functions.

Answer 1

I guess you are looking for a Singleton. Maybe this will help you:

• Android multiple activities access one java class

If you are using a SQLiteOpenHelper I HIGHLY recommend you to read this:

• Correctly Managing Your SQLite Database

I think you should be fine with Approach #1 which uses a singleton with the abstract factory pattern. Read the article its very informative. More on the topic and Pros n cons are here
