Android programming, layouts and activities

February 20, 2010 - 23:13 — jwatte

I've been doing some Android programming, trying to get a feel for what an Android app would look like when structured as a main screen, some set-up screens, and a main gameplay screen (which then wants to go back to the main screen). I've fought a bit with the built-in Android layout views. They seem to be missing some capabilities that would be really useful.

tester

July 22, 2009 - 19:58 — jwatte

A simple command-line program that exercises parts of the Etwork API and asserts if something fails. Think of it as an API acceptance test.
