public class TypoDetector
extends com.android.tools.lint.detector.api.ResourceXmlDetector

Check which looks for likely typos in Strings.

TODO:

• Add check of Java String literals too!
• Add support for additional languages. The typo detector is now multilingual and looks for typos-*locale*.txt files to use. However, we need to seed it with additional typo databases. I did some searching and came up with some alternatives. Here's the strategy I used: Used Google Translate to translate "Wikipedia Common Misspellings", and then I went to google.no, google.fr etc searching with that translation, and came up with what looks like wikipedia language local lists of typos. This is how I found the Norwegian one for example:
  http://no.wikipedia.org/wiki/Wikipedia:Liste_over_alminnelige_stavefeil/Maskinform
  Here are some additional possibilities not yet processed:
  • French: http://fr.wikipedia.org/wiki/Wikip%C3%A9dia:Liste_de_fautes_d'orthographe_courantes (couldn't find a machine-readable version there?)
  • Swedish: http://sv.wikipedia.org/wiki/Wikipedia:Lista_%C3%B6ver_vanliga_spr%C3%A5kfel (couldn't find a machine-readable version there?)
  • German http://de.wikipedia.org/wiki/Wikipedia:Liste_von_Tippfehlern/F%C3%BCr_Maschinen
• Consider also digesting files like http://sv.wikipedia.org/wiki/Wikipedia:AutoWikiBrowser/Typos See http://en.wikipedia.org/wiki/Wikipedia:AutoWikiBrowser/User_manual.
