Android adb install unsuccessful (facebook integration)

Android adb install unsuccessful (facebook integration)

I have installed android-SDK (not ADT bundle - actually I don't know its
purpose), Eclipse, added ADT plugin into Eclipse and added several virtual
devices.
According to the manual on fb dev. site, I was trying to install facebook
with this command:
./adb install ~/facebook-android-sdk-3.5/bin/FBAndroid-3.5.apk
But it turned back this error:
error: device not found
I also managed to import android library from facebook-sdk and attempted
to launch an example file. The result:
Failed to install HelloFacebookSample.apk on device 'emulator-5554':
device not found
[2013-08-28 17:46:37 - HelloFacebookSample]
com.android.ddmlib.InstallException:
device not found
[2013-08-28 17:46:37 - HelloFacebookSample] Launch canceled!
Any idea what have I missed?
