context

Related implementation to Java (Eppo-exp/java-server-sdk@11c33e3). Since we are targeting android api 21, we are limited to an older API.

isPresent, which require API level 24 or higher, you'll need to find alternative approaches. The Optional class and its methods were introduced in Java 8, and Android started supporting Java 8 language features from API level 24 onwards. This means methods like isPresent and isEmpty are not directly available on devices running lower API levels.

implementation of semver support using available APIs.

since we passed isValid we should be confident that parse will succeed without an exception

// Android API version 21 does not have access to the java.util.Optional class.
// Version.tryParse returns a Optional<Version> would be ideal.
// Instead use Version.parse which throws an exception if the string is not a valid SemVer.
// We front-load the parsing here so many evaluation of gte, gt, lte, lt operations
// more straight-forward.
