Hi there..
Eye Candy
To be able to do this, you need a good library that you want to wrap. A library like this will run inside a webview as its purely javascript, so some knowledge of HTML5 at most and some css will be recommended. I'm still learning both through trial and error.
Secondly, I wanted to trap the events that happen within my components, so I used webview extras for that.
Thirdly, I wanted to have the library include internaly the javascript and css files that I'm using. Please note the respective licenses for that. I decided on some community based libraries.
Steps
1. Create a project in b4a and insert the normal library attributes... Here is an example. This should be in the Main activity
2. My library is based on the premise that it will run inside a webview, so I needed to create a page where all components will sit. This I created a page class to be a holder using HTML5 methodology. This page will parent the other components, will fire javascript code using WebViewExtras etc and will get and set components attributes during run time.
As my page will fire events, I created some events and also some design properties (this I will test later on). This I did by adding a CustomView class and updating the events...
3. I then defined some global variables I will use and also the interface with the webview extras library on this page class...
From above, the most important crucial things are the webview (we will render our components in it), the JarFileLoader (this extracts js and css files from the compiled .jar file), the WebViewExtras, WebChromeClient and JSInterface), without these, this library would not work at all.
The output of the final library for me has been the Eye Candy above, all purely javascript and some css.

B4X:
#Region Project Attributes

B4X:
#Event: TileClicked (value As String)
#Event: TabClicked (value As String)
#Event: MenuClicked (value As String, childIndex as string)
#Event: GroupButtonClick (value As String)

#Event: RatingChange (element as string, value as string)
#Event: Loaded ()
#Event: RangeSliderRead(value1 as string, value2 as string)
3. I then defined some global variables I will use and also the interface with the webview extras library on this page class...
B4X:
Sub Class_Globals
Public ID As String
Private jsFiles As List
Private cssFiles As List

Public EnumIcons As IconsEnum
End Sub
