Hi, I was developing for Android first and am now doing iOS. I do think that Android is a bigger challenge than iOS, primarily because you have to cater to many different screen sizes. Sure, you have the iPhone 5 which is taller than the other iPhones, but it's more about "clipping" the content for the smaller ones rather than "scaling" the UI up or down for a screen size and Android OS version. It's also heaven how you can have arrays and dictionaries (maps in Java) that contain different data types in Objective-C, even blocks of executable code!

I used to do just Java and knew no C or C++. Below are the references that best helped me to understand the programming philosophy of Objective-C (it's easy to learn the syntax, but why code is being written a certain way is different).
