Hi I had the problem that Admob did not deliver ads on Fire TV devices because I needed google_play_services_version: 12451000, but I only had 10084000, it took a long time but I managed to do so by deleting com.google.android and com.google ads and copied back from another app (with 1245100), added in the manifest <meta-data android: name = "com.google.android.gms.version" android: value = "@ integer / google_play_services_version" /> copy the following in the RES folder under Values / integer.xml ...
<integer name = "google_play_services_version"> 12451000 </integer> however it works ... ;-) ps if I did something wrong now I'm sorry ..
