Hello ! I read a lot of posts about how to read it when I touch the touch screen with several fingers (gesturedetector). There is an internal lib in b4a, but I couldn't find the one used for it. Then, the example programs I found are more than 10 years old, and it doesn't work with them, because on the phone, when the program starts, it says "the program is not compatible with the phone" (samsung galaxy a14)
What is the simplest solution if I want to read the position of several fingers? Thanks in advance !
