copied!<p>You have four realistic solutions i would say in my opinion</p> <p><strong>1-</strong> Threads</p> <p><strong>2-</strong> Asyntask</p> <p><strong>3-</strong> Service</p> <p><strong>4-</strong> External lib</p> <p>If you are doing lot of small downloads classic <strong>Theading</strong> is the best option maybe with a service to manage it, but not forced.</p> <p>For one simple download you can use <strong>Asynctask</strong> alone. It can be enough but you must know several things about this method : AsyncTask can be "Bugged" according to the way you use it.</p> <p><strong>Service</strong> is good you can use it. A download module using service is a good idea to manage the requests.</p> <p>The best solution for a quick/efficient developement is to use a library that do the work for you. But in your case you are using SOAP... If you where using Json you could make use of <strong>Volley</strong> which is very good and fast.</p> <p>Maybe try to use this one which is well known </p> <p><strong><a href="http://code.google.com/p/ksoap2-android/" rel="nofollow">http://code.google.com/p/ksoap2-android/</a></strong> </p> <p>with the how to <strong><a href="http://code.google.com/p/ksoap2-android/wiki/HowToUse" rel="nofollow">http://code.google.com/p/ksoap2-android/wiki/HowToUse</a></strong></p> <hr> <p>For the moment when to do the operation you have several solutions</p> <p><strong>1-</strong> In background without blocking the ui, updating the ui View per View</p> <p><strong>2-</strong> Using a loading screen (bad for user experience but sometimes you don't have a choice)</p> <p>In your case you would have the loading screen between the first activity and the second using a ProgressDialog maybe</p>
