Hi, sorry - I haven’t emphasized that for OH 2.4 you need either
- upgrade to OH2.5 first
- to manually install a newer gson jar
- edit the MANIFEST.MF file in META-INF dir in the provided jar, so the newer gson is not required (the code works with the bundled gson in OH 2.4 as well)
change
com.google.gson;version="[2.8,3)"
to
com.google.gson;version="[2.4,3)"
thanks
Ondrej
