The problem is that you are not running ProgressDialog in a UI thread.

Add a handler that will handle messages in your UI thread.

private static final int UPDATE_STARTED = 0;
private static final int UPDATE_FINISHED = 1;

private Handler handler = new Handler(){
  @Override public void handleMessage(Message msg) {
    switch (msg.what) {
     case UPDATE_STARTED:
       progressDialog = ProgressDialog.show(ConnectActivity.this, "",
            "Loading. Please wait...", true, false);                
     break;  
     case UPDATE_FINISHED:
       if(progressDialog.isShowing()){
         progressDialog.dismiss();    
       }            
     break;
    }
  }
};


private void processThread() {
  Message m = new Message();
  m.what = UPDATE_STARTED;
  handler.sendMessage(m);

  //Your working code

  m = new Message();
  m.what = UPDATE_FINISHED;
  handler.sendMessage(m);
}

good luck!
