Hello everyone,
I'm new to Android development, and I'm not sure why I'm getting this
exception when I'm rotating the screen.
08-05 21:15:43.850: ERROR/ActivityManager(276): fail to set top app
changed! (2)
java.lang.NullPointerException

You can see the code here <http://pastebin.com/03GpfSLw>. Also, I noticed
that in the code here:
if (fragment != null) {
the fragment becomes null when the device rotates after the progress dialog
is shown.
Thanks!
