I have not heard about Android for a while. Today, I finally heard somethings about that. Android 4.3 will be available.
But there are some improvements only, without any very impressive new functions. The major updates are:
-Multiusers mode:
- A device can be login by different users and you can have a profile for each user to restrict their right too.
- Better 3D
- it has a new rendering engine for games
- Gesture Keyboard
- That is the most impressive I think. You can swift the multi keys to type. That looks similar with SwiftKey.

If you are Nexus 7 user, I think you should have it.

We started to build ios app again. But I drop iAd banner on the panel and run the app. I got this error "Could not instantiate class named ADBannerView".
Well, that is a silly mistake. I just forgot going the project and add iAd.framework at Linked frameworks and libraries in the target, just like before:

I found facebook messenger apps has voice call function. Actually, I believe this function are in there for few months. But recently, I found that accidentally. While I opened a conversation and clicked "i" icon, which is the contact information, then I found there is an option for "free call". Then I tried that in Android. The voice quality is not bad, that is better viber. But the webpage has not this option, that is too bad. This option is not obvious in the app. A lot of friends don't know about that. Anyway, that is a good function to try. That is free and acceptable voice quality.

Few weeks before, I went to westfield carindale. There were a Samsung Roadshow. I have tried the Galaxy Note 8. That is nice, and I like the S Pen too. I can draw and operate the phone by that. Moreover, that is light too. That is cool. But I got Galaxy S3 and iPad Mini, I don't need that at all.

Recently, there is a version of Skype in Android. In this version, the interface is completely re-built! They used the tab layout, they are "Recent","Favorites" and "People". Moreover, the contact list will be your home screen for Skype, rather than old "Main Menu" style. That is more similar with more than IM problem. That is easier to contact the people in your contact. But I had some friends to use Skype as a softphone. They said that is harder to use. Personally, I like the new layout more, that is easier to use. The most of time, I call the people in my skype contact list.
By the way, I found the new version is more stable, but skype is still eating a lot of battery! I found next version can improve this.
