アンドロイドで依存関係を追加する際にエラーが発生しました

次のコードがあると、gradleは正常にビルドされます。アンドロイドで依存関係を追加する際にエラーが発生しました

ext { 
    supportLibVersion = '23.2.1' // variable that can be referenced to keep support libs consistent 
} 

dependencies { 
    compile fileTree(dir: 'libs', include: ['*.jar']) 
    compile "com.android.support:appcompat-v7:${supportLibVersion}" 
    compile "com.android.support:design:${supportLibVersion}" 
    compile 'pl.pawelkleczkowski.customgauge:CustomGauge:1.0.1' 
    compile "com.android.support:recyclerview-v7:${supportLibVersion}" 
    compile "com.android.support:cardview-v7:${supportLibVersion}" 
    compile 'com.rengwuxian.materialedittext:library:2.1.4' 
    compile 'com.loopj.android:android-async-http:1.4.9' 
    compile 'com.wdullaer:materialdatetimepicker:2.3.0' 



}

しかし、私は以下の依存関係を追加したときにエラーが出ると述べました。

compile 'com.afollestad.material-dialogs:core:0.8.5.9'

エラー

任意の提案。おかげ

完全Gradleのファイル
