Understanding Processing

Great! I just started to learn about the origin of "Processing". I understand how powerful is Processing as a learning environment programming tool.
(Reference to: Processing: A Programming Handbook for Visual Designers and Artists by Casey Reas & Ben Fry)
.pde = Processing Development Environment

Processing also can create both the applet and Java application. Cool...
Just downloaded and installed the jdk-7u3-windows-i586.exe. (trying the Android in Processing he he he...)
Ok. done with jdk installation and proceeding to install the android-sdk-r16-windows.exe (installer version).
Hmm.. several addon.xml cites (mainly the mobile phone) are refusing connection...
