To load the data from server it is better to use Asynctask along with ProgressDialog. And to load images Lazy loading of images is the best solution.

1. Always keep the UI work on UI thread, and Non-UI work on the Non-UI thread, was a good programming approach, but became a law with the arrival of HoneyComb android Version.

2. When an Android App start you begin on UI thread, now to keep UI thread responsive, we need to do all the process heavy task on the Non-UI thread.

3 You can do this using a simple thread along with Handler, where you do the Non-UI work in the thread and then show the Output on the UI using the Handler.

4. The other better approach is AsyncTask, which was introduced in android, and is also known as Painless Threading. This automatically Synchronizes the UI and Non-UI thread.

5. Now about the Delay, this sometimes depends on your Internet connectivity... But yes using the thread to handle different Non-UI work and then putting it on the UI thread, helps in reducing the lags...

Can you mention by link to blog or example on web? #Kumar Vivek — Mohammad Abu Hmead, Sep 09 '12 at 11:12
