I received an e-mail asking me to advertise another Android training material. And I do it because I have never seen an Android training in video format before.
Here it is, lo and behold.
I have to admit, I am a bit skeptical. If there is a text material and video (e.g. on a news site), I always choose the text because I read pretty quickly. But I leave the decision for you. Try the free sample (increase the resolution and make it full screen, then it becomes readable) and if it works for you, consider subscribing to the course for an - IMHO - quite modest fee.
