You can use this library github.com/pents90/svg-android only for android.
Andengine (IDK if still in development) has an extension using this library https://github.com/nicolasgramlich/AndEngineSVGTextureRegionExtension
LibGDX is not integrating this kind of feature because cannot support all platforms, just android, you can integrate this manually if your plan is Android only,
Or make different way to load textures in the other platforms using:
This returns enum -> Application.ApplicationType values: Android, Desktop, HeadlessDesktop, Applet, WebGL, iOS.
NEW Fork -> AndroidSVG: https://code.google.com/p/androidsvg/, this one supports 1.2 speficication.
Not supported at all: Animation is not supported, Filters are not supported.
