Best way to get lat and long from gps and sending to a server to get data back using expandable list view android
<p>what is the best way to design an expandable list view, the details for the list view will come from server after the device sends the latitude and longitude to the server. </p>

<p>I am early learner on AsyncTask, as User Interface might freeze when getting lat,long and sending the same to the server and getting back branch details. Some example, pointers would be helpful. 
Looking forward to reply.
thanks.</p>
