How do you add an external library (in this case, kryonet) to a libGdx project in Android Studio? I've seen people telling it's related to the build.grade, but where do you put the jar file or how do you import it?
Find the "build.gradle (Project : projectname)" file, under "project(":core") { dependencies {" add this line:
compile "com.esotericsoftware:kryonet:2.22.0-RC1"
Android studio will prompt you for gradle sync, do it, after it's done you can now call the kryonet classes. Happy days :-)
