Answer 1

You can encapsulate your data in a Bound Service as described in this document:

http://developer.android.com/guide/topics/fundamentals/bound-services.html

Don't forget to add your server to the manifest file.

this solution has the advantage of decoupling your data from your UI, which will ultimately lead to a more maintainable design.

If the need arrises you can add a messaging wrapper to your service's API to allow it to be called from other processes / applications
