I follow this tutorial https://www.b4x.com/android/forum/threads/raspberry-pi-with-java-11.99606/ on a Rpi 3+ and I get this error message:

Thank you for your answer Erel, Effectively a blank UI program do not throw the error. I am also able to create a layout and it shows, but as soon as I add a button I have the error. I did not test all the views but I know a label works but a button crash.

I also have another question, is it normal I cannot see the program running in a VNC viewer I can only see it on an HDMI display.

Thank you Erel, it works. In fact I raised GPU memory to 196 in the configuration tool.

I had to raise it to the max. Runs "ok" (as expected not that fast). Non-UI apps run like hell. I have a server app on my CentOS VPS (the cheap plan with 512MB RAM only) and I can create and insert 1500 invoices to a MySQL db in 3-5 secs :cool::D
