Скачать или смотреть How to show progressbar/ image while waiting for function (INET/ IP addr) to finish in Android App?

In this vidoe it shows how to display a wait bar or a progress bar (indeterminate mode) while waiting for a function or method to complete its execution in the Android App.

In this example, it tries to get the INTET address for a website. However, this method can be implemented for any other functionality.

For asynchronizedexecution, it uses ExecutorService from the java.util.concurrent class as the asynctask is deprecated in the Android now.
