title: Ionic Native Google Map Geolocation watchposition is not working
body: <p>I am using @ionic-native/geolocation to track the user's position.</p>
  <pre><code>startTracking() {
  
  console.log(&quot;startTracking&quot;);
  
  this.positionSubscription = this.geolocation.watchPosition()
    .subscribe(data =&gt; {
      console.log(&quot;subscription&quot;);
      console.log(data.coords.latitude);
      console.log(data.coords.longitude);
    });
  
   }
  </code></pre>
  <p>But when I change the position, nothing happened.
  What's wrong? I am trying on android emulator.</p>
