[android-developers] Thoughts of the design and development in an android environment

Hello Everyone,

I have got a software design question which is related to android development (because I have already started to develop it in android.) But there is a few things I want to know and have idea's about.

The system

It is about an adnroid app which is created to run on tabs. The App will be used in an production environment. Meaning on an assembly line. At the beginning of the line the product is added to the system and on two other places on the line these products need to be updated with some information, which the user will fill in.

So to be concrete: There will be 3 android tabs which will have to be connected to the same database. Preferably a website or maybe one tab can serve as a master and the other devices as a slave. Also there is 3 tabs which all work on the same app but with a diffrent view.

Also I would like to know wether it is possible to handle a FIFO (first in first out) system on this. Meaning when the person on screen 1 adds a product to the system, the second person wil automatically get this record on his screen. And the second one after he finish to handle the first product.

I would be very much interested on how to set this up in an android environment.

Concrete questions

So here are my concreet questions:

1. How would you combine 3 tabs to work on one and the same app.
2. Is it possible to do this in an master/slave environment
3. Can you have the 3 devices to work from a different view (Fracgment / Activity) on the same app.
4. What are the options in case there is a weak internet connection? Local/ networks / internet etc.
5. Any suggestion for good hardware to use?

Thanks very much.
