Actually point 9 is his most valid point. It is harder to figure out the more complicated things in Android because there are simply fewer developers actively sharing what they know. Which means you have to figure some stuff out by yourself and/or hunt for some code that is similar.

As an example, it is Google's fault but try dealing with an application that uses Fragments that also wants to utilize the non-Fragment Map View.

The best resource for real Android is CommonsWare.
