title: Canot Resolve symbol 'GeoFirestore'
body: <p>I am creating a Map based app on Android Platform . I am using Firebase Firestore as backend Database in this project. I wanted to add GeoFire in my Firestore database . I have added following dependencies in my gradle file  to add Firestore and GeoFire in my project:</p>
  
  <pre><code>implementation 'com.google.firebase:firebase-core:16.0.4'
  implementation 'com.google.firebase:firebase-firestore:17.1.2'
  implementation 'com.firebase:geofire-android:2.3.1'
  </code></pre>
  
  <p>but after sucessfull gradle sync when i add </p>
  
  <pre><code>CollectionReference geoFirestoreRef = FirebaseFirestore.getInstance().collection("my-collection");
  GeoFirestore geoFirestore = new GeoFirestore(geoFirestoreRef);
  </code></pre>
  
  <p>It gives Error 'Unable to resolve GeoFirestore'</p>
  
  <p>I dont understand why this error appears although i have added all the required dependencies in my gradle file . Attached picture also.
