It doesn't work because you are blocking the UI thread. You are not
"streaming" the UI at all like I suggested you do. You need to show the
dialog, then build the views by little batches so that you never block the
UI thread for more than a few milliseconds at a time. Otherwise your app
will appear frozen and might even get an ANR if the CPU is busy with another
task,
