Add AdMob Ads to my app

Question

I am learning to develop Android app from online tutorials and I got lots of answers from "stackoverflow" and am very thankful to the website and it's users for their help.

This is my first question to this community/forum. However, I got lots of answers and tutorials on different websites for this question but no luck.

Simply, I want to add AdMob ads to my app. They must be appear in all pages/activities of the app.

Please see below mentioned codes for the app. If someone can provide codes including admob it would be great help!
