I ran into this post: How to call Android contacts list?
Unfortunately I'm reading that it's old and Android 2.0 changed how this works, but this post fails to link to a new method of accomplishing this. Google also appears to either lack results, or I'm not searching for the right thing. I'd like for a user to be able to select a contact on my app... how do I give them a prompt to select 1 user, then for a task to be executed when that user is selected.
