There are some good points, but there's room for a lot more. Relating strictly to the points raised in the article: * Be aware that Android has interface surfaces outside the GUI. Respect their implied interaction affordances. Be aware of how their position creates your combined interface layout. * Respect local interface paradigms. Directly porting interfaces between platforms will usually create usability issues and aesthetic conflicts. * Respect local development paradigms. Stop trying to do everything from scratch and use the tools you're expected to use. Break the rules when you know them intimately and have a good reason. On Android, this means getting cozy with Intents (among other things).
