title: Google Maps, No Option for Starting the Navigation, Only Preview is there
body: <p>In my application, I am starting the Google Navigation with the help of following set of code.</p>
  
  <pre><code>String uri = "http://maps.google.com/maps?saddr="+ gpsLatitude
              + "," + gpsLongitude
              + "&amp;daddr="
              + updateAcceptedOfferDetailsData.getDestinationLat()+","+updateAcceptedOfferDetailsData.getDestinationLon();
              Intent intent = new Intent(android.content.Intent.ACTION_VIEW,
                      Uri.parse(uri));
              intent.setClassName("com.google.android.apps.maps",
              "com.google.android.maps.MapsActivity");
              startActivity(intent);
  </code></pre>
  
  <p>I am passing the Source Lat/Lng and Destination Lat/Lng of the respective addresses.</p>
  
  <p><strong>Problem:-</strong> Here my problem is when the Navigation Screen opens there is no option to <strong>"Start"</strong> rather there is another option <strong>"Preview"</strong>, This problem do not happens at all the places it works fine for some places but not for all. May I know what the whole mess is??</p>
  
  <p>Thanks</p>
