Android Activity Class Not Found just before creating first project

Question

I downloaded Android Studio this morning. I have a background in Java, and I have professionally developed in PHP+Mysql+Jquery. I'm following android developers tutorial, but when I created the first project (i guess it's supossed to be a 100% functionally Hello World), and setted up an AVD emulator.

But when I run the new project it throws me a FATAL ERROR with the next log:

Change your target sdk version to 19

check here targetSdkVersion setting

Do not use API Level of 20 and Platform 4.4W, as Android Virtual Device. With Level 19 and Platform 4.2.2 set on AVD everything runs as it should.
