I have a project that I've made for Android. I've built it both with and without Admobs Ads.
With the Admob plugin (without any events called) the build displays a black screen.
Without the plugin, it displays the game.
I need Ads in my game, but I'm unsure of how I would do that without the plugin working.
I do have the Admobs plugin installed with Cordova, and it builds without errors.
You can check my thread here, I had same problem. Finnaly I found the easiest solution for admob where you dont need to recode anything in Android Studio or gamefiles except 1 string in config.xml, so changing something in your ands and rebuilding .apk or iphone format takes seconds instead of all those actions which takes quite a lot of time if you are not exactly a programmer.
B.t.w admob ads will not show in construct preview. I reccomend to run Bluestacks or alternatives (AndroidStudio adb was not a solution for me coz I am working on Ryzen)
