Any new files you open should have syntax highlighting.
several people have asked for smali highlighting for notepad++. thanks to furrelkt for having already sent me an example. here's what i've come up with: https://sites.google.com/site/lohanplus/files/smali_npp.xml
for dark backgrounds, try this: https://sites.google.com/site/lohanplus/files/smali_npp_darkbg.xml
there are many limitations for notepad++'s user defined language. i could not get many tokens to highlight correctly, or as well as ultraedit or the highlighter used on this blog. perhaps a full lexer plugin could handle it. if you write one or make improvements to this xml, let me know.
