How to add and import .jar files in android stduio

Question

I am following this link: http://programmerguru.com/android-tutorial/how-to-call-asp-net-web-service-in-android/#project-structure to add the soap service in my project. I need to add this file: ksoap2-android-assembly-2.4-jar-with-dependencies in my project.

So my question is how can I add the above .jar file in my project to avoid the red highlighted errors in the image below?. Thanks in advance

Did you tell the gradle script to compile your jar file?

you can follow this link Android Studio: Add jar as library?

Simply add this line in your app gradle

implementation files('libs/ksoap2_3.6.3.jar')
