I have an Andoid app that performs multiple salesforce queries to update one screen in an activity.  I am running into a refresh problem with the screen because all of these Salesforce queries are each an asynctask.  I tried putting all of the salesforce calls into a master asynch task so I could use post execute, but that didnt work.  I read about Android loaders here, http://developer.android.com/guide/components/loaders.html   Has anyone used loaders to fix this issue, or is there a different way I can address the issue?  I need to know when all of the salesforce queries are complete so I can refresh the screen.

Thanks for your help. =o)
