What do you recommend to read for Android developement? The SO documentation is not that great for me since I'm just strarting to create some apps?

Can anyone recommend a good notebook for mobile/desktop developement? Mainly Java, Android, .NET and Unity3D projects. Dedicated GPU is a big plus.

Read an article about "Who is gonna grab the position of Google ". Nice jnsight about how a giant like Google can lose control of Android , due to proliferation of cross platform apllications . Instilled fear in my mind due to my lack of mobile developement knowledge . Interesting perspective on how cross platform developement can trigger downfall of Android..
