Once you create an android application, integrate AdMob ads with that application is quite difficult for beginners, actually integrating AdMob is such an easy task that it takes not more than 5 minutes.
In this post, I will share the correct procedure that how can you add AdMob banner ad on an android studio. So when the user opens the application it should show ads immediately. Please note that you have to choose the Google Admob activity template provided by Android Studio.
Now, this configuration is very easy. Open android studio app, click start new android studio project, give a name for your application. It can be anything, for example, Ad_example then click next. Next, you need to choose API 9: Android 2.3 Giga break. This will run almost all the android application, and that why we choose this one. If you choose android lollipop, it might run just 20% of android phone or device. But older version will work on all most all the device. Click next, then choose Google Admob ads activity this will automate our ads then click next, you can go with default ad fragment, the only thing you need to make sure you choose Ad format as a banner instead of Interstitial then click finish. That all you need to do.
