Tabbed Application with location listener implemented in tabActivity tabHost

Question

hi. here is my problem.

i have an application that has a tabActivity and 3 tabs. all off the tabs use a location listener and work with locations. i implement onPause and onResume for every tab to remove and start listening for location accordingly. is this the right way to go? i had another idea to work with and that was implementing a location listener to the tabActivity and doing broadcasts to the child tabs with the location, but it seemed more complicated.

the problem with my current solution is that whenever i switch tab i lose the location i got in the previous and i cant use getlastknown location because i dont want the last location on start of the application.(does this make sense?) what can i do to solve this problem.

a thing that will work better will be to have one variable that will hold the last location from the onLocationChanged and i can observe its changes and call methods onChange.

are there any suggestions about my issue, maybe some tutorials,examples, anything that might work. tnx

You could definitely do that. Or, you can implement a service which each of the 3 tabs bind to, though you'd probably still need to send broadcasts. Doing broadcasts really isn't all that complicated. Just register/unregister each broadcast receiver in each tab's onresume/onpause
