Android Question How to handle programmatically Group Remote Database

[JNG]

Need suggestion how to handle the following situation programmatically.
A remote database is having several tables and associated with group(G). Further a group is having several sub groups(around 50 nos.)(SG) .. and each sub group is having 100-200 associated sub group(ASC). Each ASC is having 1000-4000 users.


I am facing a problem to handle the following situations.

1. When an user from any of the Associated Sub group (ASC) starts the application the Starter service should fetch the data only related that user from the remote database.
2. When an user changes its phone how to handle this situation.

How are you identifying the users? Do they log in to your application?

True I have a login process and registration process also but my problem is when user login in Main activity how I should manage the starter service should fetch only the concern user data.

Because the starter service automatically starts in the background is useful, mean time user login it access the data from remote server.

Check whether there is already a signed in user and only if there is download the data. You can use CallSub to call a sub in the starter service that will download the data after the user has signed in.

Thanks for the solution

Its means calling a starter service from activity using callsub is as good as we are using starter service.
