B4J Question Any news about gpio controlling on raspberry 4 ? I cannot use openjdk-8-jdk but liberica.

The library pi4j appears to be abandoned. Is there any alternative ? I must use Liberica because I need UI. So this tutorial https://www.b4x.com/android/forum/threads/raspberry-pi-4b-gpio-not-working.118488/ is not good for me...

There is currently no alternative. Pi4J is the only Java based solution.

Creating non-ui programs should be simple: https://www.b4x.com/android/forum/threads/raspberry-pi-4b-gpio-not-working.118488/#post-741684
