title: Failed to resolve Firebase auth 15.0.0
body: <p>I am new to android development environment and I need to connect my app to firebase but I am getting this error</p>
  
  <blockquote>
    <p>Failed to resolve: firebase-auth-15.0.0</p>
  </blockquote>
  
  <p>This error is shown in the statement:</p>
  
  <pre><code>implementation 'com.google.firebase:firebase-auth:16.0.1:15.0.0' 
  </code></pre>
  
  <p>This statement contain details of two versions, I think the error is caused due to this, but this particular statement is provided by firebase itself. See the image:</p>

  <p>I tried to change the above statement to</p>
  
  <pre><code>implementation 'com.google.firebase:firebase-auth:16.0.3'
  </code></pre>
  
  <p>But then firebase dependency is not setting up.</p>
