问题
I'm having weird trouble with Apache Batik library linked to my Android&LibGDX project.
But let's start from beginning, in IntelliJ Idea I have a project which contains three modules: Main, Android and Desktop.
"batik" library which I highlighted contains:
And there is some code in "Main" module which is used in Android&Desktop modules:
String parser = XMLResourceDescriptor.getXMLParserClassName();
SAXSVGDocumentFactory factory = new SAXSVGDocumentFactory(parser);
Following code is used to get SVG document's width and height, but calling SAXSVGDocumentFactory's constructor throws an exception only on Android. There is no problem on Desktop version which runs without any problems:

There are also a lot of messages in Logcat send by dalvik and related to org.apache.batik.dom.* classes, which as far as I see are included in batik-svg-dom.jar:

What causes this problem?
回答1:
Batik uses Java2D API, which is unavailable on Android. You need to use another library.
