I found there is a Linux version of Skype. Although that is still a beta version, the functions are quite completed. I can use SkypeIn, SkypeOut, sending SMS and some normal functions, such as message and voice chat. There is only one weakness. UI is not as nice as the Windows Version

My Android Tablet, Acer Iconia A500, got an update package this morning. Now, it became to Android 3.1. That sounds running more smooth......, I know it has more enhancements, such as re-sizable widget... I will try them later.

Most of friends are good at Java recommended Eclipse to me as my main IDE for Java. There are a lot of plug-ins, such as spring IDE. But I still feel more comfortable to use NetBeans. Because I spent some time using Netbeans many may years ago. Morover, I felt NetBeans is more similar with Visual Studio, that seems to be more C# programmer Friendly. As a C# programmer, so I choose it. Besides, Netbeans support Spring MVC3 and Hibernate which are the frameworks I need to use. It can fulfill what I need. Thus, NetBeans is my choice!

Finally, I completed Android Notepad Tutorial. It helps me to understand SQLite database in android. Moreover, it shows how to do some advance UI, such as ListView. I recommended all Android Newbie need to read it!

I am design the architecture of my android app now. At this stage, I am considering the interface between my app and the server. I am thinking to use the XML SOAP protocol. This is because the XML is very heavy weighted. There are Extra text in xml , such as "". So, I choose to JSON. Because that used less text. Moreover, I think JSON is good to de-serialize in Java. But GlasshFish does not come with JSON webservice by default. I have to use some extra package. I need to learn in Java!
