I was organising and cleaning up my Google Drive and found this pdf file about Android Graphic System I wrote back in 2014. It is 62 pages. I will never be able to update it and make it better and/or up to date, since I have moved to other area recently. I'm not not sure how useful it is now, but anyway I will share it here. https://drive.google.com/file/d/0BxzOKllGjbpdOVd4UlpOWUlxM2c/view?usp=sharing
