Getting NoClassDefFoundError

[AndroidDev08]

Hi,

I added the certificate transparency logger to my project and I am getting the below crash for NoClassDefFoundError.

implementation 'com.appmattus.certificatetransparency:certificatetransparency-android:1.1.0'

java.lang.NoClassDefFoundError: Failed resolution of: Lorg/bouncycastle/tls/TlsUtils;
at com.appmattus.certificatetransparency.internal.utils.X509CertificateExtKt.parseSctsFromCertExtension(X509CertificateExt.kt:52)

This looks likely to be a conflict with the version of bouncycastle being resolved by your project. Some of these classes moved from version 1.6x to 1.7x which we currently use.

It would be worth running ./gradlew app:dependencies and seeing what versions were resolved
