[android-developers] Re: how can I check if an Activity is visible or not?
Well, that is actually not a bad idea. Thanks for the tip !

Since you're going to do this from your service, why don't you have your
Activity register with the service when it is started or resumed, unregister
when it is paused or stopped, and then just have the service keep track of
whether the activity is active that way?

if ( the user is using my app) {

I was checking in the Activity/ActivityManager public interface, but I
dont quite get how to check if the user is actually using my
application of not.
Can you explain me a bit more how to do this with the approach you
mention ? or if there is an alternative way to do it ?
Thanks again for the time.

If your code is in a service a good way to do this is to just have the
activity tell the service when it is resumed.

My question is because I want to implement a service and only invoke
a
different activity (by launching an Intent) only if the previous
activity was visible. In case for instance, the user is in a
different
application I just want to send a notification.
My problem is that I dont know how to determine if my application is
being use at a particular time, so, I can properly move to the user
to
the right screen.
Thanks !
