By default, AAR does not include any dependencies. Solution mentioned by @Hector should work for gradle plugin < 3.0. For Gradle plugin 3.0+, try custom config as mentioned here.
android { ... }// Add a new configuration to hold your dependenciesconfigurations { myConfig}dependencies { .... myConfig 'com.android.support:appcompat-v7:26.1.0' myConfig 'com.android.support:support-v4:26.1.0' ...}task copyLibs(type: Copy) { from configurations.myConfig into "libs"}
