I am using the volley library to perform network operation in android. So I am trying to add this library in my project which is created in Android Studio and gradle system
This is probably a rare case, but for me a library that was included in the settings.gradle was not there.
E.g. I had: include ':libraries:Android-RateThisApp:library' in my settings.gradle
but the folder Android-RateThisApp was empty. As soon as I checked out this submodule the gradle sync succeed.
