I sometimes receive requirements for Android apps that include a design for what was an iPhone app. The people sending me these things think I can just create exactly the same thing on Android and everything will be ok.
Unfortunately, Android has different UI idioms and it’s necessary to translate iOS UI idioms to Android. Android Patterns is a new resource I recently came across that might help people sending me these designs. It allows you to think in terms of Android and provide me with something that is much closer to what is to be implemented.
