Planning to develop a SAP Enterprise Portal application with version 7.3 SP3 and above? wondering how and where to start? continue read on..

You may be wondering why this article, since there are tutorials already available in SAP SDN community about developing a portal application. I tell you, if you are coming from portal application development background with other platforms such as WebSphere, Web logic, SharePoint etc., There is good chance that you will be confused with how and where to start. SAP have made simple things complex and introduced several jargon's and keywords.

Android Main thread says :I Still know what you did last summer

The latest version of android does not allow network activities on its main thread. It is a very good principle, so that the app will appear to load faster and you can do the costly operations in the background. So what would you do if you want to make a network connection when the app loads? One of the recommended solution android provides is the use of Async Task. This class is a wrapper over the java timer task and will do the processing in a seperate thread. This design provides an opportunity for the main thread to continue its job while the async task work in the background to finish the networking activities.
