TokenD Kotlin SDK

This library facilitates interaction with TokenD-based system from Kotlin or Java applications including Android apps.

Installation

For Gradle add following lines to your project's build.gradle:

allprojects {
    repositories {
        /*...*/
        maven { url "https://maven.tokend.io" }
    }
}

dependencies {
    /*...*/
    implementation "org.tokend:sdk:4.1.0"
}

Usage

Setting up and making requests

const val TOKEND_URL = "https://api.testnet.tokend.org"

// Use TokenDApi facade members to access particular endpoints.
val api = TokenDApi(TOKEND_URL)
val assetsPage = api.v3.assets.get().execute().get()
val systemInfo = api.v3.info.getInfo().execute().get()

// Use KeyServer instance to work with key server.
val keyServer = KeyServer(api.wallets)
val wallet = keyServer.getWallet(email, password).execute().get()

Making custom requests

If there is an useful new endpoint which is not yet defined in one of TokenDApi inner APIs you can work with it by making custom requests from TokenDApi.customRequests:

val api = TokenDApi(TOKEND_URL)

// Use Class to get data with simple type.
val response = api
        .customRequests
        .get("/extra_endpoint", ResponseData::class.java)
        .execute()
        .get()

// Use Type obtained by TypeToken to get
// data with generic type.
val collectionType = object : TypeToken<List<ResponseData>>() {}.type
val collection = api
        .customRequests
        .get("/some_collection", collectionType)
        .execute()
        .get()

RxJava integration

If you would like to use RxJava in your project check out Rx extensions for SDK.

Android integration

TokenD SDK works fine on Android targeting JVM version 1.8. For correct ProGuard processing check out the rules from TokenD Android client

Generate resources

Use TokenD mobile resourcegen Docker image to generate Java resources from OpenAPI docs.

Create unit test in org.tokend.sdk.dev test package and use DockerResourceGenerator
to generate resources directly from IDE.

Example of usage:

val generator = DockerResourceGenerator(
        tempDirectoryPath = "~/git/tokend/sdk/gen"
)
generator.generateResources(
        openapiSpecFilePath = "~/git/tokend/horizon/docs/build/openapi.yaml",
        namespace = "org.tokend.sdk.api.v3.model.generated",
        outputDirectoryPath = "~/git/tokend/sdk/src/main/java/org/tokend/sdk/api/generated",
        ignoredKeys = setOf()
)
