General Guidance to General Guidance to Smartphone DevSmartphone DevPick a platformLearn a bit about the OS in general

◦Understand the environment in which your app will run

◦How the OS treats scenarios like multi-tasking

◦Could help with things like performance tuning

Get the toolsLearn the APIs

◦Learn as you go – it’s easier to pick what you need and learn it when you need it instead of trying to learn all the APIs beforehand

Design is key for consumer apps
