B4XSwitch to support Accessibility [B4X]
I think that the B4XSwitch does not support accessibility very well. I made a simple extension based on the already extended version of the B4XSwitch that supports setting colors at runtime. (Many thanks to @Blueforcer.) Now you can add a description to the panel, which is read out correctly by TalkBack.

GPSGNSS Library
After discovering several problems in the operation of GPS and GNSS libraries on SDK32 and SDK33, I decided to make one library that will be compatible with almost all versions of android (from SDK less than 24 to SDK33 and above). This library combines deprecated GPS classes with still up-to-date GNSS classes and, based on the android version, decides which one to use.

SD FlexGrid [B4X] [XUI]
I created a new library to show a table (or grid) similar to the one in EXCEL. There are already excellent classes that allow many to accomplish things, such as xCustomListView (by Erel) and with the FlexibleTable (by Klaus). I wanted to make something slightly different suited to my needs.
