How to use a library project in android studio

I’m not sure if it’s already possible to add a library project via the IDE (-> without any problems).
I do this by configuring the gradle files of my project like this:

• create a folder in your root project directory named libs
• copy the folder datetimepicker-library to libs

• add this library in your settings.gradle with the following command:

  include ':libs:datetimepicker-library'
  

• go to your build.gradle file of your AppProject and add the following line to your dependencies:

  implementation project(':libs:datetimepicker-library')
  

• at least you have to sync your gradle files: Tools -> Android -> Sync Project with Gradle Files

Please try this. If you get errors please post the log file.
