I am getting this without proguard on Android API 19.

It seems to have to do with the java version on different phones. It will work fine on the pixel, but cause an error on the S7.

Samsung A7100 android 6.0.1, LG f260s android 19 similar error as above. SecretKeyFactory PBKDF2WithHmacSHA256 implementation not found

These types of errors are unfortunately beyond my control. Device manufacturers decide for themselves what kind of algorithms they support.

A solution would be to use https://github.com/rtyley/spongycastle as your security provider. This is a fully complete rename of Bouncy Castle specifically for use with Android. Vendors tend to strip down the Bouncy Castle implementations shipped with their phones.
