Hi, Temoana Thanks for replying..
I have done all these steps earlier I exported as APK debug, enabled test ads, given Application ID, given my Publisher ID, Privacy policy URL and enabled "Test mode, even put the test ads code from admob but the problem is the application is not even opening on any android devices after adding steps for showing ads.before that its working fine.
I want to know the steps involved in adding a banner ad on the front page pls give a screenshot if you've done any ads on your project before.
Thanks
