title: AdMob and Firebase
body: <p>I have added AdMob advertising in my Android app .</p>
  
  <p>I connected to the AdMob site using this link:</p>
  
  <p><a href="https://firebase.google.com/docs/admob/android/quick-start" rel="nofollow noreferrer">https://firebase.google.com/docs/admob/android/quick-start</a></p>
  
  <p>I have few questions:</p>
  
  <p>Is it possible to achieve AdMob Advertising WITHOUT Firebase?</p>
  
  <p>Is Firebase FREE and CLEAR to the developer? Can I insert AdMob advertising into my app with the Firebase and then do not worry about anything else. Like, payment and/or any OTHER INFORMATION.</p>
