How to run background service in Oracle MAF

In mobile apps, we often need some services to run in the background to do tasks like fetching or updating data from a server, sync local data with a server, invoking APIs etc.
In this post, we will see how to run a task in the background of a mobile app developed using Oracle MAF.

There is a default utility available in Oracle MAF to run java code in background threads which is MafExecutorService. It has a method execute() to run java runnable on a background thread in the context of the calling thread's MAF feature context. The syntax of the method is like

MafExecutorService.execute(new Runnable()
{
public void run()
{
         //Invoke your methods here     
}
});

If you update any data change events in the background, invoke below method to make it effective.
