Hi Guys,

I'm using B4A 9.5 at the moment testing with Smartphone Android 9
C:\java\jdk-11.0.1\jdk-11.0.1\bin\javac.exe
C:\Android\platforms\android-28\android.jar

Edit: I found the tutorial..

no reason to use 9.5. Update to 9.8; it is free

Follow the installation instructions.


It will just work.

it's not important if is free or no.
Sometime is better to keep the version that is working and update later when we have extra free time (just in case)

I think I can solve it following the tutorial.

Anyway, thanks @DonManfred :)

Look like I have to do that:
