Are you using components like jPOI? You have to do some configurations then: https://www.b4x.com/android/forum/t...distribute-standalone-ui-apps.117880/#content

No , it worked before but after adding an additional library i got this problem:
at b4j/net.labymod.opus.OpusCodec.loadNativesFromJar(Unknown Source)
at b4j/com.tillekesoft.b4jopus.B4jOpusWrapper.Initialize(Unknown Source)

Try to add:

#PackagerProperty: VMArgs = --add-opens java.base/java.lang=b4j

Good chances that it will not work. Not all SDKs are compatible with Java 9+ modules system.
