-This project contains Java classes and interfaces that are shared between the LaunchDarkly Java and Android SDKs. These are internal implementation details that are not part of the supported SDK APIs and should not be used by application code; no types in this package should be exposed directly in the public APIs. Code that is specific to one or the other SDK is in [java-server-sdk](https://github.com/launchdarkly/java-server-sdk) or [android-client-sdk](https://github.com/launchdarkly/android-client-sdk), and public APIs that are common to both are in [java-sdk-common](https://github.com/launchdarkly/java-sdk-common).
