running a program on a real device

i want to run an application from developer documentation , second lesson "running your app" , ( i couldn't write the site, as it is forbidden for new users)
on my android device, but it doesn't start, i installed usb
driver, activated debugging ( so i see it in device manager), but it
doesn't start on my android device,
even it doesn't start on AVD, but i don't know why

Check out your project api version and than create the avd with the same api version.

if the app will crash it's programming issue.

for real device install the device driver's on your system. once it will installed the android environment will recognize the device and it will show on run configuration menu.

Is adb running?

If so type, start a command prompt and type:

adb devices


You should see a list of your connected devices and any emulator running.
