Android Question Error with Firebase Auth (java.lang.NoClassDefFoundError: Failed resolution of: Lkotlin/jvm/internal/Intrinsics;)

[Bossolo]

Hi everyone,
i'm tryng to use Firebase Auth but i get an error when i tryng to SignIn, i will post the log at the end.
I've already update all the B4A file (OpenJDK, SDK and command line), i'm using versione 12.80, and installed from SDK Manager all the suggested item (unless Android Emulator). I've also tryed to add "#AdditionalJar: kotlin-stdlib-1.7.21" as suggested in other thred but i will get another error during the compiling because B4A can't find the jar file

Delete your Android SDK.
Download a new one based on these instructions: https://www.b4x.com/b4a.html

No need to run B4A Sdk Manager.

 

[Bossolo]

Already did 2 times, same error. I've also download again OpenJDK14 and reinstalling B4A.exe

 

[Erel]

Which version of B4A are you using?
Please post a screenshot of Tools - Configure Paths.

 

[Bossolo]

Version 12.80 64bit

 

[Erel]

The preinstalled package includes all components needed for FirebaseAuth.

I recommend you to uninstall B4A. Make sure that the internal libraries folder was deleted and if not then delete it.
Reinstall B4A.

 

[Bossolo]

Unistalled, verified the internal library's folder was deleted, and reinstalled; same error.
Tomorrow i will try with Oracle JDK 8 instead OpenJDK14, maybe i will be lucky

 

[Erel]

The Java version is irrelevant.

Carefully follow the instructions and it will work.

I've delete with a software all trace of B4A and SDK, then i reboot the PC and reinstalled everything, but the error was still there.

With other search i found the solution in this thread and this thread.
First i downloaded from mvnrepository the kotlin-stdlib-1.7.21.jar and insert it in the internal libraries, then via SDK manager i downloaded the arch.core dependencies, in the end i add this two lines and now it works

#AdditionalJar: kotlin-stdlib-1.7.21.jar
#AdditionalJar: androidx.arch.core:core-runtime
