I'm not entirely sure I believe you...
Still with that aside, have you check the Commands / Advert section?
It appears to have Facebook AdMob., Amazon and Chartboost.
Mind if you're looking of ways of generating revenue., why not create a Fantasy Cricket League that people can play?
If you have IAP to purchase Tokens that they can use to Buy & Sell Players via a Market for their Teams... and then can win back Tokens based on how successful they're doing.
I mean I'm sure you know how a Fantasy Sports League thing goes.
And it's not Gambling, so doesn't break the Indian Mobile App Rules; cause you're not paying anything out nor is there any randomisation.
It'd probably make you a bit more than Ads would as well; after all I don't imagine the CPM is too great., in-fact you kind of proved that when you were talking about the Firebase support a little while back being a little broken.
Just a thought.
