I can not add a dependency in Android Studio - android-studio

Question

I'm new in Android Studio and i want to add dependency to custom view (https://github.com/glomadrian/dashed-circular-progress) in my project. I downloaded *.arr file from Maven repository and imported it like a AAR module. But i can't compile my project because there are some exceptions with this custom view: ClassNotFoundException. Could someone explain me step by step how to correctly add dependencies from maven rep? or there are some problems with this DashedCircularProgress.aar? Thanks.
build.gradle
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.2"
defaultConfig {
applicationId "com.ahryk94gmail.mibandsdk"
minSdkVersion 19
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
repositories {
maven {
url "http://dl.bintray.com/glomadrian/maven"
}
}
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.1.1'
compile files('libs/gson-2.6.2.jar')
compile 'com.github.glomadrian:DashedCircularProgress:1.0#aar'
}

Answer 1

As mentioned in the project description you have to add the following code to build.gradle:
repositories {
maven {
url "http://dl.bintray.com/glomadrian/maven"
}
}
dependencies {
compile 'com.github.glomadrian:DashedCircularProgress:1.0#aar'
}
UPDATE:
Also you can use jitpack.io and download the dependency right from GitHub.
repositories {
maven {
url "https://jitpack.io"
}
}
dependencies {
compile 'com.github.glomadrian:dashed-circular-progress:59d245a'
}
