Java SDK reference
View as MarkdownThis reference covers the Dex Java SDK. Check the resolved version of io.superdurable:dex-sdk in your Gradle or Maven build before you rely on a detail:
./gradlew dependencyInsight --dependency io.superdurable:dex-sdk
Install
The Java SDK is the Maven Central artifact io.superdurable:dex-sdk. Pin an exact release:
io.superdurable:dex-sdk:1.37.0
The published classes target Java 8 bytecode. Releases use the tag sdk-java/vX.Y.Z.
Supported versions
| SDK minor | Server requirement |
|---|---|
| 1.37, 1.35 | server-zd 0.1.17 or newer (protocol version 4) |
| 1.32, 1.31, 1.30 | See the compatibility matrix |
Minor numbers follow the shared Dex release train. A missing minor means the Java SDK did not change in that release.

RPC stubs and Kotlin
Client.newRpcStub creates a subclass of the Flow. A Java Flow class and its RPC methods must not be final. Kotlin makes both final by default, so declare the Flow class and its RPC methods with open.
