copied!<p>I am implementing jeremyfeinstein sliding menu library. for this I have an activity which extends SherlockFragmentActivity. for this activity I have two fragments one is for left menu and another is for Main screen. Everything is working fine and smooth but still I have a problem that is when my Sliding menu activity starts, it becomes blank for 8-10 seconds. after 8-10 seconds my main screen fragment becomes visible. <strong>this is my base class:</strong></p> <pre><code> public class SlidingFragmentActivity extends SherlockFragmentActivity implements SlidingActivityBase { private SlidingActivityHelper mHelper;

I have removed all the libraries and now I am using only support library(4 and 7) with navigation drawer with same result. </p>
