Iroha 3

Appearance

Android, Kotlin, and Java ​

The current JVM-facing mobile SDK in the workspace is IrohaAndroid. It ships Android and JVM artifacts for Kotlin and Java applications.

Gradle Setup ​

Point Gradle at the Maven repository that hosts the published artifacts and add the dependencies you need:

kotlin
repositories {
    google()
    mavenCentral()
    maven { url = uri("../../artifacts/android/maven") }
}

dependencies {
    implementation("org.hyperledger.iroha:iroha-android:<version>")
    implementation("org.hyperledger.iroha:iroha-android-jvm:<version>")
}

Local Sample Build ​

bash
./gradlew -p java/iroha_android :samples-android:assembleDebug \
  -PirohaAndroidUsePublished=true \
  -PirohaAndroidRepoDir=$PWD/../artifacts/android/maven

Quickstart ​

java
import org.hyperledger.iroha.android.address.AccountAddress;

byte[] key = new byte[32];
AccountAddress address = AccountAddress.fromAccount(key, "ed25519");
System.out.println(address.canonicalHex());
System.out.println(address.toI105(753));

AccountAddress.DisplayFormats formats = address.displayFormats();
System.out.println(formats.i105);
System.out.println(formats.i105Warning);

Current Coverage ​

The Android/JVM SDK currently focuses on:

  • key management and secure-storage backends
  • Norito encoding via the shared Java implementation
  • Torii HTTP, streaming, and Norito RPC clients
  • offline note, QR, and subscription helpers
  • account address and multisig utilities
  • generated instruction helpers for NFT and RWA flows
