Unable to add library

[meet2011]

I tried to add library but it gives error. Have a look at the build gradle

build.gralde(project-level)
// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.0'
        classpath 'com.novoda:bintray-release:0.3.4'
    }
}

allprojects {
    repositories {
        jcenter()
        mavenCentral()
    }

}

build.gradle(app level)

apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.2"

    defaultConfig {
        applicationId "xxx.xxxx.xxxxxx"
        minSdkVersion 9
        targetSdkVersion 25
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

dependencies {
    compile 'com.google.android.gms:play-services-ads:8.1.0'
    compile 'com.android.support:support-v4:25.2.0'
    compile 'io.github.kobakei:ratethisapp:x.y.z'
    compile 'com.android.support:appcompat-v7:25.2.0'
}

@meet2011 Try to replace compile 'io.github.kobakei:ratethisapp:x.y.z' with compile 'io.github.kobakei:ratethisapp:1.1.3'
