Using GPS information in Activity and also in service

[nemopeti]

Hello,

I wrotte an application, deals with GPS data.
The working method:
- set global GPS in main activity, and initialise it
- start the service
- in service modul start the gps, and set a call to self in later time

the service sends gps data to webservice, witch works well. But If the main activity on the screen I like to display the gps data in the activity too.

Can someone suggest me a correct solution for this?

Regards,
Peter

You should move all the GPS code to the service. You can use CallSubDelayed to interact between the service and the activity: Using CallSubDelayed to interact between activities and services

Ok, thank's for your quick answer.
And how can I detect thad the Main activity is on the screen? Becouse if it's not in the screen, than not nessesary to call it's function.

You can use IsPaused(Main).
