I got proguard error :

The problem was in com.github.tinder.scarlet:scarlet-lifecycle-android module this module included all third-party libs from scarlet (Jackson, Moshi , Rxjava1, RxJava 2 etc)

the solution is to exclude scarlet module from scarlet:scarlet-lifecycle-android

implementation ("com.github.tinder.scarlet:scarlet-lifecycle-android:$scarlet_version"){ exclude group: 'com.github.tinder', module: 'scarlet' }

Hope it will be useful

I had this same issue and took me quite some time to figure out it was an issue with Scarlet, it'd be great if the configuration shared by @SergiyKorotun can be added to the README to help future devs.
