Thanks. I've added it to the readme.

Hi @nielscup,

I'm the friendly issue checker.
Thanks for using the issue template 😘
I appreciate it very much. I'm sure, the maintainers of this repository will answer, soon.

And it did work before you updated? I never used proguard. Just a guess: Maybe the referenced Support libraries are different (one of us is using the a newer one)?!

[nielscup]

Yes it did, I get the same error when I enable proguard in SMS.Fingerprint.Sample.Droid. It might have something to do with the new Samsung part, I will have look.

Hmm but I didn't touch the samsung part in 1.4.1 o0

[nielscup]

I didn't update either since 1.3.5! But it is definitely the Samsung part. If I remove the Samsung reference from Plugin.Fingerprint.Android the error goes away. The error also disappears when I set Linker behaviour to Don't link in (in SMS.Fingerprint.Sample.Droid). Could you check if you have the same behaviour on your side?

PROBLEM SOLVED: if you use proguard you need to add the following lines to your Proguard.cfg

-dontwarn com.samsung.**
-keep class com.samsung.** {*;}
