On Android, XMLReaderFactory.createXMLReader() returns parsers like org.kxml2.io.KXmlParser or org.xml.sax.helpers.XMLReaderFactory$Driver that aren't in XOM's known-parser list, and these parsers don't support the external-general-entities/external-parameter-entities SAX features — causing setupParser to throw and Builder construction to fail entirely on Android.

Changes

• Builder.parsers array — adds org.kxml2.io.KXmlParser and org.xml.sax.helpers.XMLReaderFactory$Driver so they are recognized by findParser and knownGoodParser

• setupParser — adds a named special-case branch for the three known Android parsers (org.kxml2.io.KXmlParser, org.xml.sax.helpers.XMLReaderFactory$Driver, org.xmlpull.v1.sax2.Driver) that skips setting the external entity features for those parsers only, consistent with the existing Crimson workaround pattern; all other parsers still require external entity support

// Android parsers do not support external entity features; skip setting them.
else if (parserName.equals("org.kxml2.io.KXmlParser")
  || parserName.equals("org.xml.sax.helpers.XMLReaderFactory$Driver")
  || parserName.equals("org.xmlpull.v1.sax2.Driver")) {
    // skip
}
else {
    parser.setFeature("http://xml.org/sax/features/external-general-entities", true);
    parser.setFeature("http://xml.org/sax/features/external-parameter-entities", true);
}

• BuilderTest — testNonEntityResolvingParserException is unchanged: parsers that explicitly reject external entity features are still rejected with XMLException
