title: How do I pull data from another thread or process (Android/Java)
body: <p>I know of concepts that allow inter-process communication. My program needs to launch a second thread. I know how to pass or "push" data from one thread to another from Java/Android, but I have not seen a lot of information regarding "pulling" data. The child thread needs to grab data on the parent thread every so often. How is this done?</p>
