Recently I've been contemplating to create a new App with the true "Android Design",new Android Design does not mean Theme.holo(which was added it api level 14,android 4.0), and I found a website in which android design is carefully talked about thoroughly:Phonekr.com.
Now look at the picture below, it's google's official Android Developers website,except the addition of "Design" tag, in which you can find android official given "colors , patterns " and other design principles, you can also find a "Training " label , there you can find an easy and new access to write a brand new app according with the latest android design elements such as Action Bar,Drawer...etc.
Here I want to make a list of the training program,although I know it's surplus,superfluous..It kind of help me remember when I need'em.
