Question

I want to use BouncyCastle for GnuPG encryption (want to get .gpg file) in android. But I am getting this error.(Unsupported class file major version 59.
Failed to transform bcprov-jdk15on-1.67.jar (org.bouncycastle:bcprov-jdk15on:1.67) )

My gradle version is: gradle-6.7.1-bin.zip
JAVA_VERSION="1.8.0_242"

Please help.
Or if somebody can suggest me some other way to do GnuPG encryption in android, that will also be very helpful.
