Hey folks, Based on some conversation in IRC yesterday, I updated my Android sketch further. In addition to supporting creation and deletion of tasks on the rhcloud server, there's now an abstraction called AeroGearCollection, which works like this: tasks = new AeroGearCollection("tasks", Task[].class); tasks.add(new Task("Arrange rental car")); AeroGearCollection associates a backend URL with a Java class for JSON mapping and a set of operations. Check it out at https://github.com/gdaniels/android-data. A couple of points: 1) AeroGearCollection seems similar to, but perhaps not quite the same as, the Pipe abstraction? 2) The AeroGear "libary" stuff (in the org.aerogear.android package) does not itself deal with asynchrony/Intents/Services/etc, and that's left to the application (org.aerogear.proto...). In the near future we may want to provide these components so as to make the user-facing APIs simpler to use. Thoughts/questions/comments appreciated. Thanks, --Glen
