Android Example B4Xgoodies_from_walt61 Online

Well,

As JamesGreaves requested,
"So do you not think it would be of value to have even something like @walt61 has created but online?"
https://www.b4x.com/android/forum/threads/complete-library-repository-click-here.109921/#post-686347

I got thinking about it. How hard it is to convert walt61's such a good hard work into online.
Converting the given xlsm to Google Sheet gave reload error.
Xls without macro also gave same reload error.
I made csv and tried to open in sheet, still same error.

Finally I opted for csv to html, http://www.convertcsv.com/csv-to-html.htm and then pasted the html text in a new gsheet. Voila it works !

Please note that the information is (c) walt61 and I will remove the link if not authorised to upload a online version of the same.

I just wanted to help fellow members here with an online option of the same.

B4AMultiple items3D Body 4 librariesThere are three libraries, doing similar thing with variations:
1. A 3D cube, with or without dice numbers on, can roll by touch or by command or provide a throw result by click.
2. A 3D library for any body, provided that you know how to define its verteces and polygons. There are examples of several bodies which may help, see photos.
3. A 3D library for any body (like 2 above), using Open_GL 1 library (thanks to Agraham). Note that I have very limited knowledge on the use of Open_GL and this implementation is very basic, however the user of this 3D library does not need any knowhow of Open_gl at all. In all libraries you can create a view which is a base panel and the body on it. The panel may be transparent or with a bitmap.

B4AOtherActivityRecognitionThis library allows you to monitor the user / device physical state (walking, running, still, etc.). The state detection is based on Android location services which use low power sensors to try to detect the current activity. Once you connect your app to these services you will receive notifications even when your app is in the background (similar to static intent filters). It requires Google Play Services to be installed. This library will not work with the latest version of Google Play Services.

B4XChartsxChart Class [B4X] [XUI]Learning B4XViews and XUI, I wrote this CustomView xChart Class.
It works on all three products: B4A, B4i and B4J.
The xChart.bas file is located in the B4J and shared, relative link, in B4A and B4i.
The code is exactly the same, one class file, for all three products.

It is an evolution of Erels' Android Charts Framwork.

It has automatic scales, automatic text size according to the chart size.
These can also be set manually.

Demoprograms for all three products.
Tested on PC, Android Samsung S6, Samsung Tab S2, iPhone 6 and iPad.
