When to use tink java vs tink android?

[ColtonIdle]

I'm working on a library that will be used in my android app. the library for now is a jvm library and not android specific, but I do see that there is an android artifact available. So I guess my question is should I update my library to "narrow down" its scope from being a jvm library to being an android-only library since I should use tink-android. or are the differences minor/superfluous?

The two libraries are actually not the same, and they might diverge more in the future. We want to take advantage of the a
Android platform and different javax.crypto implementations available, and have the option of using different code which might be useful for performance. Currently, they already differ for example for RsaSsaPss signatures where we avoid Conscrypt on older android versions explicitly.

In addition, Tink android provides a few more APIs for the use with Android Keystore. I hope that helps.

gotcha. i will make sure to use java-android if im on android. right now im using the java variant in my android app and it seems to work fine... but seems like i could run into problems in the future.
