Question: What were your initial impressions of Android development?
Answer: Maxim Petrov: Android developing (and actually, any software developing) is not about knowing the language - languages are just tools, so adding a tool to a toolbox is usually not a problem (I moved to Android/Java/C dev right from Ruby - and these are completely different languages). Given experience with any other languages, you can move to Android pretty quickly, at least start prototyping something, though, you need to fight the initial quirks (like SDK installation, lack of good documentation, android SDK/Eclipse and framework bugs, and the Android core devs' "you can't do that, please don't do that").Android development infrastructure is very immature, while Android end user can never notice the immaturity of the platform (as actually, it's not so immature on end user side), the development side of things is really lacking in many areas.
For example, documentation is lacking, often conflicts with real state of things and it's just not enough. Though, this is balanced by the fact that Android is open source - you can just go check the source, and the source is the best documentation, but you need to get used (I am) to this approach. For example, Honeycomb sources are not published yet, and this immediately raised questions, like how do they activate that menu button in bottom status bar.
