My program does some network activity in a background thread. Before starting, it pops up a progress dialog. The dialog is dismissed on the handler. This all works fine, exc

I faced this same problem, and I came up with a solution that didn't invole using the ProgressDialog and I get faster results.

What I did was create a layout that has a ProgressBar in it.

Then in the onCreate method do the following

public void onCreate(Bundle icicle) {
    super.onCreate(icicle);
    setContentView(R.layout.progress);
}

Then do the long task in a thread, and when that's finished have a Runnable set the content view to the real layout you want to use for this activity.

For example:

mHandler.post(new Runnable(){

public void run() {
        setContentView(R.layout.my_layout);
    } 
});

This is what I did, and I've found that it runs faster than showing the ProgressDialog and it's less intrusive and has a better look in my opinion.

However, if you're wanting to use the ProgressDialog, then this answer isn't for you.
