When I have following code gradle is build successfully.
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' } But when I added below dependency it stated giving me error.
