title: Remove firebase analytics from android app completely
body: <p>I added firebase analytics in my app just to try it out. I followed the steps in official guidelines.</p>
  
  <p>Now I have decided against it. I have undone whatever I had done to add it.
  (Removed entries from project level and app level build.gradle; removed all usages from source code.)</p>
  
  <p>But I am still getting logs like this when my app runs:</p>
  
  <pre><code>I/FirebaseInitProvider: FirebaseApp initialization successful
  </code></pre>
  
  <p>This leads me to believe that I haven't removed it completely. This is really a matter of concern for me now because my app has exceeded method count limit and I have had to enable multidex.</p>
  
  <p>How can I completely remove firebase from my app?</p>
