kotlin-platform

kotlin-platform is the library that supports Platform functionality for the Java VM on desktop and Android devices.

Directory Layout

• dash-sdk-android - This is for the Dash SDK that supports platform for all Android architectures
• dash-sdk-bindings - This generates the primary Dash SDK header and the shared library for Java bindings for the local machine
• dash-sdk-java - This is for the Dash SDK that supports platform for the local environment
• dpp - This is the Kotlin Dash SDK for Platfrom
  • This is a more simple interface than dash-sdk-java that supports the needs of the DashPay app which uses dpns and dashpay data contracts.
  • It depends on dash-sdk-java and dash-sdk-android if targeting android
• examples - Contains many example programs that perform some platform operations
• platform-mobile - A rust crate used by dash-sdk-android and dash-sdk-java that supports many Platform DAPI operations
• tools - a module that contains the WalletTool program

Build Instructions

See dash-sdk-bindings readme for build instructions of the basic bindings system. Perform these steps first.

Java Bindings for Desktop

See dash-sdk-java readme for build instructions of the Java bindings. Perform these steps second.

• This will generate the Java classes for the Java bindings and the shared library that supports the current environment
• There are currently problems when running on Linux 64-bit systems. Mac M1 systems work well. No other systems have been tested.

Java Bindings for Android

Build the android libraries for the local machine (only works on Mac)

./gradlew publishToMavenLocal

Build the android libraries to publish to Maven Central:

1. Verify release & deploy configuration

./gradlew jreleaserConfig

2. Ensure a clean deployment

./gradlew clean

3. Generate all needed code for SWIG and Protobuf

./gradlew generateSWIG && ./gradlew generateProto

4. Stage all artifacts to a local directory

./gradlew publish

5. Deploy and release

./gradlew jreleaserDeploy

Use in other projects

dppVersion = "2.0.0"
dependencies {
    implementation "org.dashj.platform:dash-sdk-java:$dppVersion"
    implementation "org.dashj.platform:dash-sdk-kotlin:$dppVersion" // dpp
    implementation "org.dashj.platform:dash-sdk-android:$dppVersion" // for android only
}

Operating Systems

Currently only building for Android on a Mac is supported.
