Problem with android build !

Hi guys !

I wanted to create a basic application on android. But when i builded it nothing appear.

First, I installed JDK x86. Then, i downloaded bundle SDK android, and installed the good api and usb driver, with other tools.

when i builded it, it asked me the folder of the SDK, then when i give it, no error appear, but there is no build. Same for Build & Run.

Is there a way to build without have this problem ?

ps : i also allowed on my nexus 4 usb Debug

Thank you for your help guys !
