Android Question Minimum android version for Camera2

[ThePuiu]

There is a minimum version of the operating system to be able to use the Camera2 library?

I tried on a tablet with Android 4.1 and it gives the following error message:

Logger connected to:  samsung GT-P6800
** Activity (photo) Create, isFirst = true **
camex2_class_globals (java line: 144)

Then I tried on an ASUS ZenPad tablet with Android 5.0.2 where it didn't give an error message but it didn't work either! but at line:

Wait For(PrepareSurface) Complete (Success As Boolean)

return Limited

On Android 9 the code works without problems.

Camera2 library is based on the newer Camera API introduced in Android 5 (API 21). It is therefore supported by Android 5+ devices.
It requires B4A v7.3+.
