One of the best things about libGDX is that you can use it to deploy to multiple platforms: as an Android app, embedded in a webpage, or as an executable desktop application. However, this also means that you can’t just use any library with libGDX: Java libraries don’t work in Android or as a webpage, Android libraries don’t work on desktop or the web, and JavaScript libraries don’t work as a Java application or Android app.
