Defunct link in README and clarification about libsignal

[IacobusKopiirefuto]

In README.md the link to location of libsignal-service-java inside Signal-Android source code now results in 404 - page not found.

extracted from the [Signal-Android source code](https://github.com/signalapp/Signal-Android/tree/main/libsignal/service).

Related question, could you clarify the situation with the libsignal-service-java?

The official Signal's repository has been archived since Feb 12, 2022 and has been replaced by libsignal it seems.

README.md mentions that signal-cli uses patched libsignal-service-java and this @Turasa 's repository is still updated.

But when Signal official libsignal-service-java where do you get updates for it? Could @AsamK or somebody else who knows it clarify this?

Given lack of information it raises question of how and for how long can signal-cli catch up to official Signal development - when it fact everything might be just fine and only the README.md is outdated. : )

[AsamK]

The directory for upstream libsignal-service-java inside Signal-Android has changed, I just updated the link in the README. Thanks for the hint.

The upstream libsignal-service-java ist just a module in Signal-Android. I'm using a script to get the changes from there and add them to the patched libsignal-service-java fork. The fork repository also has an upstream branch (https://github.com/Turasa/libsignal-service-java/tree/upstream) which just contains the copied unpatched upstream libsignal-service, with just some additional build files.

libsignal is a lower level library, that's used internally by the libsignal-service module.

Thanks a lot for a prompt reply and explanation. : )

Just to double check. So before 2022 Signal had one big library for Android called libsignal-service-java but now they split it to libsignal-service with Android/Java specif code and platform-agnostic APIs of libsignal which is used by libsignal-service as well as other services of other platforms.

And signal-cli takes the upstream of libsignal-service and because of this also uses the libsignal as well, right?

[AsamK]

Yes. Signal created libsignal to share code between their different platforms and then replaced the corresponding code in libsignal-service.
