I have read https://developers.google.com/admob/android/quick-start?hl=en-US#import_the_mobile_ads_sdk
I need to initialize MobileAds using Code A in order to display Ad
Initializing MobileAds in Aplication context will cause error with InMobi mediation adapter
"Adapter Initialization status: Not Ready"
Tested with AdMob Test Suite.
Solution is to initialize MobileAds in Activity context.
