I am implementing admob rewarded ads in my app but i am not sure if its correct according to the policy to lock on of the features of the app on the main menu and unlock them on watch the video ? is it ok to do so ? is it according to the policy
You first read all the AdMob ads related policies and confirm.
AdMob provides AdListener. You can set this listener with AdView and you can use it's override methods. AdListener
listener will be executed when any action perform with AdView
. Like when Ads Open, Ads Load, Ads Closed everytime related method will execured by listener.
Like,
adView.setAdListener(new AdListener());
please check this link for more detail about AdListener
.
