Affdex Gradle Failed to resolve

Question

I’m not able to add dependency. It keeps throwing me the error:
Failed to resolve com.affectiva.android:affdexsdk:3.2 .
I’ve added maven repository but still it’s giving me error.

Project Gradle:

allprojects {
repositories {
    jcenter()
    maven { url "https://maven.google.com" }
    maven { url "http://maven.affectiva.com" }
    maven { url 'https://jitpack.io' }
}
}

App Gradle:

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:26.1.0'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    compile 'com.affectiva.android:affdexsdk:3.2'
    testCompile 'junit:junit:4.12'
}

I get this following error

Error:(28, 13) Failed to resolve: com.affectiva.android:affdexsdk:3.2
