Question

I have a service that is retrieving URL’s from a remote server for a MainActivity that i launch at the beginning of the project.

The problem is, i need these URL’s before the Activity its ran.

The service is launched when the activity is started for the first time.

I put the URL’s in the sharedpreference once they are retrieved.

But by the time this happens the activity has already loaded the default images.
I am using an Adapter to LazyLoad the images.

How can i notify the activity to refresh it self or refresh the BaseAdapter i am using to download the images once the service is finished?

Any better idea’s are welcomed!

If you need to update the Activity from the Service, you should look into BroadcastReceivers.
