KKBOX OpenAPI SDK for Android


SDK usage


  1. The SDK itself is implemented in Kotlin, but it can be used as an ordinary java library.
  2. It should be able to use with Android Studio 2.x.

Import the SDK

In the module which uses the SDK, add following lines in build.gradle

buildscript {
    repositories {
dependencies {
    compile 'com.kkbox:openapideveloper:1.0.0'

Prepare client ID & client secret

Browse KKBOX Developer Website and create an developer account, then create an app to get the client ID and client secret.

Use the SDK

First import the sdk packages.

import com.kkbox.openapideveloper.api.Api
import com.kkbox.openapideveloper.auth.Auth

Then obtaining the access token with the client ID and client secret you just get.

auth = Auth(CLIENT_ID, CLIENT_SECRET, context)
accessToken= auth.clientCredentialsFlow.fetchAccessToken().get().get("access_token").asString

After obtaining the access token, you may call APIs like this:

api = Api(accessToken, "TW", context)
val searchResult = api.searchFetcher.fetchSearchResult(offset=offset).get()

By the way, you can run the app in the SDK/openapi_android_developer_sdk/OpenAPIDeveloperLibraryClient directory, it may help you to know the usage clearly.

SDK document

Please browse

SDK Development

Development Environment

  1. Below applies to those who wants to develop the SDK.
  2. If you were just using the SDK, please refer to previous parts.
  3. Android Studio 3.0
    1. DON'T USE OLDER VERSION OF ANDROID STUDIO!!!, because it doesn't support kotlin development.
    2. DON'T USE IntelliJ, because it's project file is not compatible with android studio 3.0.
  4. Please use Kotlin to develop.

Develop the library

Use the android studio to open the SDK/openapi_android_developer_sdk directory to open the project for the sdk.

Test the library

First, browse KKBOX Developer Website and create an developer account, and then create an app to get the client ID and client secret.

Then, create a file ClientInfo.kt in the SDK/openapi_android_developer_sdk/OpenAPIDeveloperLibraryClient/src/main/java/com/kkbox/openapideveloperlibraryclient directory and put your client id and client secret in it.

package com.kkbox.openapideveloperlibraryclient

object ClientInfo {
    const val CLIENT_ID = "YOUR_CLIENT_ID"

Lastly, use Android Studio to open the SDK/openapi_android_developer_sdk directory, change to use the AllTests configuration and then debug.

Build the library

cd SDK/openapi_android_developer_sdk
./gradlew assembleDebug

The result aar will be in ${REPOISITORY_DIR}/SDK/openapi_android_developer_sdk/OpenAPIDeveloperLibraryClient/build/outputs/aar/OpenAPIDeveloperLibraryClient-debug.aar.

Use the library as local aar

  1. Click File > New > New Module.

  2. Click Import .JAR/.AAR Package then click Next.

  3. Enter ${REPOISITORY_DIR}/SDK/openapi_android_developer_sdk/OpenAPIDeveloperLibraryClient/build/outputs/aar/OpenAPIDeveloperLibraryClient-debug.aar then click Finish.

  4. Now the module should be copied into your project.

  5. Check the app's settings.gradle, there should be like this:

     include ':OpenAPIDeveloperLibrary', ':OpenAPIDeveloperLibraryClient'
  6. Open the module's build.gradle and add dependencies for kotlin and the library like this:

     // only projects that will directly use kotlin files need to apply kotlin-android plugin
     //apply plugin: 'kotlin-android'
     buildscript {
         repositories {
         ext.kotlin_version = '1.1.51'
         // only projects that will directly use kotlin files need this dependency
         // dependencies {
         //    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
     dependencies {
         implementation project(":OpenAPIDeveloperLibrary")
         implementation 'com.koushikdutta.ion:ion:2.2.1'
         implementation ''
         // make sure we get kotlin runtime for running the open api library module
         implementation 'org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version'
  7. Finally sync the project

  8. Now the library should be ready

Generate Documentation

Go to the SDK/openapi_android_developer_sdk directory and execute ./gradlew dokka to generate the documentation, then open the file SDK/openapi_android_developer_sdk/OpenAPIDeveloperLibrary/build/javadoc/-open-a-p-i-library/index.html.
