Can I use AdMob in android apps published on Amazon Appstore?
I have 24 apps on amazon all with admob without any filter. Amazon's policy against links to other market places not apply to ads. They only apply if you directly place a link in your app. Like, button "more games" that lead to your games on google play.
AdMob is an ad network which supports (in this context) Android applications. the Amazon Appstore is merely another platform for developers to release their applications on.
So to answer you question briefly, YES, you can use the AdMob Api, integrate into your Android app and release it on the Amazon Appstore, or Appstore for that matter (naturally, the ones that support Android apps. ;-) )
My google account got suspended so I uploaded the same apk to Amazon, now my app only show kindle ads.
I think they're influencing which ads shows up through their market, even if I am using admob. Not 100% sure right now. I've tried to at least 100 times restarting my app and even force closing my app a bunch of times but it only shows Amazon Kindle ads.
