Practical overview

When it fits

Use it when a Java or Android application needs the documented transaction-building APIs or connections to Horizon and Soroban RPC.

Who it is for

  • Java developers building applications that construct Stellar transactions.
  • Developers connecting Java applications to Horizon or Soroban RPC.
  • Android developers assessing the documented SDK integration requirements.

Documented uses

  • Add Stellar transaction-building capabilities to a Java application.
  • Connect an application to Horizon or Soroban RPC.
  • Include the SDK in a Maven or Gradle project, or add its JAR.
  • Assess the additional Android integration consideration for platforms below API level 28.
Before you choose

Requirements & limits

The repository is public and identifies the project as open source under the Apache-2.0 license. It documents Maven, Gradle and JAR integration routes.

  • The library is specifically for Java application development against Stellar services.
  • The repository documents Maven and Gradle dependency declarations and JAR integration.
  • Android API level matters: the repository says API level 28 and above needs no additional configuration, while lower levels may need the separate Android SPI.
  • The repository links to Javadoc, examples and Stellar developer tutorials for further implementation guidance.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Add Java Stellar SDK to a Java project

Declare the SDK as a project dependency using Maven or Gradle.

Before you start

  • A Java project using Maven or Gradle.

Steps

  1. For Maven, add the dependency with group ID network.lightsail, artifact ID stellar-sdk and version 5.0.0.

  2. For Gradle, add implementation 'network.lightsail:stellar-sdk:5.0.0'.

Expected outcome

The SDK is declared as a dependency in the project build configuration.

Guide limitations

  • These steps cover dependency declaration, not transaction construction or server connection setup.
