Activeledger SDK-Kotlin

To use the Kotlin SDK please Add it in your root build.gradle at the end of repositories:

allprojects {
	repositories {
		maven { url 'https://jitpack.io' }
	}
}

Add the dependency

dependencies {
	implementation 'com.github.activeledger:SDK-Kotlin:Tag'
}

For Maven:

<repositories>
	<repository>
		<id>jitpack.io</id>
		<url>https://jitpack.io</url>
	</repository>
</repositories>

Add the dependency

<dependency>
	<groupId>com.github.activeledger</groupId>
	<artifactId>SDK-Kotlin</artifactId>
	<version>Tag</version>
</dependency>

NOTE: Please update the Tag : 0.1.3

SDK Dev Instruction

Use the ActiveLedger SDK interface to Use the SDK.

Initialise the SDK

ActiveLedgerSDK.getInstance().initSDK(this,"protocol","URL","port")
Example:
ActiveLedgerSDK.getInstance().initSDK(this,"http","testnet-uk.activeledger.io","5260")

Generate KeyPair

Generating a KeyPair will give an Observable in return. User RxJava to subscribe to the Obserable.

val keyPair: Observable<KeyPair> = ActiveLedgerSDK.getInstance().generateAndSetKeyPair(KeyType,SaveKeysToFile)
Example:
val keyPair: Observable<KeyPair> = ActiveLedgerSDK.getInstance().generateAndSetKeyPair(keyType,true)

Oboard KeyPair

Onboarding a KeyPair will give an Observable in return. User RxJava to subscribe to the Obserable.

val response: Observable<KeyPair> = ActiveLedgerSDK.getInstance().onBoardKeys(KeyPair, "KeyName")
Example:
ActiveLedgerSDK.getInstance().onBoardKeys(keyPair, "ActiveLedgerAwesomeKey")

Creating and Signing Transaction

Transactions can be created using Transactions class in the SDK. User can create complete transaction or just the $tx Object and SDK will create the complete transaction. User can also create Labeled Transaction using the example below. $tx is a JSONObject that can be created by folowing Activeledger Documentation.

transaction: JSONObject = Transactions.createLabeledTransaction($tx)

Server Sent Event

Server Sent Events can be subscribed by giving the protocol, ip and port. All the functional URLs can be found in Utility/ApiURL. User can create their own ServerEventListener and observe the events or can pass null and Observe the LiveData variable "SSEUtil.getInstance().eventLiveData".

ActiveLedgerSDK.getInstance().subscribeToEvent(protocol, ip, port, url, null/ServerEventListener)

Executing a Transaction

Execute method takes a transaction and will give an Observable in return with response in String format. User RxJava to subscribe to the Obserable.

response: Observable<String> =  ActiveLedgerSDK.getInstance().executeTransaction(String transactionJson)
