Hi everyone, I can't solve this problem, it's been weeks but nothing ...
i try to bundle app on project but it says:
file signing AAB Error
jarsigner error: java.security.SignatureException: private key algorithm is not compatible with signature algorithm
I tried to create a new key, to update sdk, to directly make a new project, to update b4a but I don't get out ... help me. it is also urgent as a job but I am now at a standstill.

hi @Erel , i uninstalled everything and reinstalled from scratch doing step by step b4a installation, having everything updated.
i created a new project and created a new private key ... i have the usual problem: jarsigner error: java.security.SignatureException: private key algorithm is not compatible with signature algorithm.
I do not know what else to do because if I had to do something else it goes beyond my skills and I am also unable to publish the app which has a certain urgency because it is for a municipal body.

@Erel
as i have windows x86 and what i download from this site: https://www.oracle.com/java/technologies/downloads/#java8-windows is the java i'm using right now.
since nobody can help me and I see indifference, can you help me and understand how to put java 11 on windows x86 if the site where to download everything you need for b4a gives me java 8?
thank you...

Hi, sorry but I didn't see any indifference. Erel posted the link where you'll find instructions on how to install OpenJDK 11, instead this Java 11. See post #5 again.
