That is easy.

I am writing two Joomla components during these few days. I got a problem, how to reference a javascript file in a Joomla Component. I used to do it in a cowboy way. I hard coded the path in the template! I should keep it inside the component!

I found the documentation, in the framework, that is a method calls AddScript. It will add a script in the header section. That is nice!

Code:

I had built a new application using System.Data.Sqlite. When I run the application, I got an exception, System.BadImageFormatException.Well, I found I was using 64-bit version, because System.Data.Sqlite will call some unmanaged dlls. So, it still needs to be in 32-bit. After I changed to use 32-bit dll,then all goods. Or you can switch your build target to 64 bit and using 64 bit dlls.

You can jump to a new window by changing the content view.

Yes, then it will jump to a new window, after the action completes, my code will call "finish();" from the sub-activity. Then it will jump back to the main window.

I read a blog post from Android Developers Blog. There are a step-by-step tutorial for Gestures API. Finally, I got a more clear picture. Those gestures are to control the action of applications, like a shortcut. For example, you can write a circle on a screen, that means "Open a new file".
