If you only have three api install, the app wont build. Ive come to find that installing from lollipop (i belive that api 14) up works. You also have to install the tools. I do the extra folder as well just to be safe. Check out this video i made about setting up the android exporter. https://www.youtube.com/watch?v=HUcmePD7o9Q&t=8s Let me know if it builds (from what i understand you are having problems building the apk, if im wrong let me know please)
It's not that hard..
Drop the Admob object.
Enter the codes you create for your App on the Admob website.
Make an even with Show Smart banner.
The Example might not work, unless you put your own code in it..
And you CANNOT install the beta from the Lounge into the Steam Version. That will not work. You need to download the Beta from Steam under the properties check Beta.
Did you checked recently if it works for you? Do you have Steam Version? Could it be the problem? Which build number you use? Which Android build tools you have installed and which platforms?
I really can't figure this out...
I used the latest 291.1 non steam, but it works also on Steam for me.
all my programs have Admob, and not a single problem.
using API 26
