How to use a library project in android studio

Question

I have been trying to add this library project to my existing project in Android Studio. It's the first time I am going to use a library project and I am having tough time. I have looked around for many ways to do this from tutorials and posts around but couldn't get it done.

Answer 1

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.
