Hello, since the updates there have been on android studio I have some problems: someone to help me, I'll give you a picture.
Hi, I don't understand, What exactly do I have to do, can you please describe it to me in detail please
AdMob now requires you to specify AdMob App ID: So we added a new text filed for that without this ID ads will not work.
Hi,kindly check if you have added Admob App ID as @Sean Buildbox suggested .But i think you have added it looking at your logcat. What i required is the right hand side column that you added in error.png file.Its partial.Expand all error and post a new screenshot.
