Oh and you have to really make sure that those lines are not broken. They need to be one line. Double click the AndroidManifest.xml file in Android studio to check there's no line break / carriage return in there as this caused errors for me many times.
EDIT - Should look like:

<activity android:name="com.google.android.gms.ads.AdActivity" android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize" />

Let me know if you hit any problems

no field package.preload['ads']
no file './ads.lua'
no file '/usr/local/share/lua/5.1/ads.lua'
no file '/usr/local/share/lua/5.1/ads/init.lua'
no file '/usr/local/lib/lua/5.1/ads.lua'

no file './ads.so'
no file '/usr/local/lib/lua/5.1/ads.so'
no file '/usr/local/lib/lua/5.1/loadall.so'
either libads.so file is missing, or you did not place System.load("ads") in main activity
