Android : Why exactly am I not seeing admob ads?

I'm not yet experienced enough with admob to know where my issue is and why no ads are being shown. This is the first time I am using Google Play Services.

After importing Google Play Services library, I started to follow the tutorial on libgdx github

https://github.com/libgdx/libgdx/wiki/Admob-in-libgdx

The only thing is, for some reason, not all of the code on the wiki works in my project, giving me errors for various reasons. I did my best job googling and using my Java knowledge to improvise and create equivalent code without the errors. What I ask is, can someone, who has admob working correctly, compare their code with mine?

It would be greatly appreciated.

Thanks,

-Steve
