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
Check the settings.gradle file. The modules which are included may be missing or in another directory. For instance, with below line in settings.gradle, gradle searches common-lib module inside your project directory:
include ':common-lib'
If it is missing, you can find and copy this module into your project or reference its path in settings.gradle file:
include ':common-lib'
project(':common-lib').projectDir = new File('') //
