How might I go about including this library in an Android app?

How might I go about including this library in an Android app? afaik, I end up getting an error relating to a Field being unable to be converted to dex.

com.android.tools.r8.internal.Tb: Field name '()V' cannot be represented in dex format.

I mean does dex support java 21? If the answer is no then you probably can't

Here's a potential solution:

Downgrade jar (backporting?)

Android apps can utilize Java 17 and below, while this library is written in Java 21 and relies on third-party libraries that also require Java versions above 17. There are tools for downgrading API calls to the JVM:

1. JavaDowngrader:

I encountered errors during my attempt:

module-info.class[ERROR] Failed to transform class 'it.auties.whatsapp.socket.MessageHandler'
java.lang.ClassNotFoundException: it.auties.protobuf.model.P

2. JvmDowngrader:

I couldn't install it successfully:

Caused by: org.gradle.api.GradleException: Provisioned toolchain 
'/home/<some path>/.gradle/jdks/zing20/zing20.09.1.0-1-jdk7.0.272-linux_x64' 
could not be probed: Command returned unexpected result code: 139)
Error output

Manually downgrade the source code:

... instead of the JAR file. I expect this to be harder, but we need to ensure no blocking issues arise. The project 'devlikeapro/waha' provides helpful guidelines for this approach.

P.S.

What problems do you expect?

One more thing I want to try. It is making native library.

@Alpha62579 Have you found a way to use this on an Android App?

[Alpha62579]

I'm afraid not.
