To use Webster's 1913 dictionary on Android, install Colordict 3, an app that accepts this StarDict format. https://play.google.com/store/apps/details?id=com.socialnmobile.colordict
Next download James's S3 archive. https://s3.amazonaws.com/jsomers/dictionary.zip
You will need to extract the .dict file from inside three containers - .dz, .tar, .bz2 from innermost to outermost. 7zip handles all of these formats.
Place the .dict, .idx and .ifo files in the dictdata directory on your sdcard or local storage root. This is where colordict looks for dictionaries.
When the files are in the right place, you can run Colordict and tap the folder icon in the top right to see the dictionaries installed and set the dictionary priority. I put the 1913 dictionary above the defaults "Wordnet" and "Wikipedia." When you look up a word, ColorDict shows the definition, if available, from these multiple sources.
