Android HighCharts Library returns Error:Failed to resolve: com.highsoft.highcharts:6.0.2:

A few days ago I saw HighCharts Library is available for Android for graph.

https://github.com/highcharts/highcharts-android

I read the documentation and start it to add on my project but when I am trying to add gradle to my project I'm getting error:

Error:Failed to resolve: com.highsoft.highcharts:6.0.2:
Open File

There are two ways as they mentioned in their documentation:

A) You can download the aar from here: Highcharts and add it manually. Put the aar in the libs folder in your project structure.

B) You can add the library to the gradle dependecies from JCenter.

When I added .aar file to libs folder there is no issue but when I added below code:

HIGChartView chartView = (HIGChartView) findViewById(R.id.hc);

My project not able to find out class HIGChartView. I'm not able to find out whether it's my side issue or HighCharts Library issue.

I also downloaded poject by Github, Getting no issue on their Project also compare Gradle with their project but I'm not able to find out the issue.

My build.gradle(Module:App) :

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    defaultConfig {
        applicationId "com.kabloom.highcharts2"
        minSdkVersion 21
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:26.1.0'

    implementation 'com.highsoft.highcharts:6.0.2' // HighCharts here added

    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.1'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
}

After creating issue on github they replied and solved my issue...

Their Documentation having problem :

Incorrect Class :

HIGChartView chartView = (HIGChartView) findViewById(R.id.hc);

Correct Class :

HIChartView chartView = (HIChartView) findViewById(R.id.hc);

And Please note that the library need Gson to work so add it in your dependencies like this:

compile 'com.google.code.gson:gson:2.8.0'

Also , They replied :

Unfortunatelly Highcharts Android is not avilable from jcenter yet so you need to add library manually. You can do that by following direct instructions from A) point from readme.
