Hunspell on Android

Question

Does anyone successfully implemented Hunspell spell-checker on Android platform? Is it even possible? Did you try it? What about the results?

Thank you in advance.

Answer 1

I created a working prototype implementation of SpellCheckerService using Hunspell so it is possible! You can find it on GitHub HunspellCheckerService. Note that this is quick&dirty prototype.

Unfortunately from what I can see the suggestions generation in Hunspell is quite slow. Depending on the word length it takes between 0.5 and 5 seconds on my Samsung Galaxy S. On the other hand checking if the word is correctly spelled is fast enough.

The problem is that by default Android is generating suggestions lists for all misspelled words upfront rather than when the user clicks the word. This may make your smartphone burning if you edit a long text with loads of misspelled words (e.g. code sample).

Let me know if you have any questions regarding this prototype.

There are few of the below steps you may have to follow to atleast try to port

1. Try to run the unix form or windows form of application which comes along with the source code.
2. Before porting you need to find out the interface layer of the Hunspell, so for that you can take help of Chromium platform where this is already part of it - to Achieve that,

Chromium code browse http://google.com/codesearch#OAMlx_jo-ck/src/third_party/hunspell/src/hunspell/hunspell.cxx

git repository for chromium http://git.chromium.org/gitweb/?p=chromium/chromium.git;a=summary 3. Please browse through and find ou the interface. 4. Now you need to create the .so from Hunspell lib, then creat Java Native interface to expose the API's of Hunspell.

Write a desired app...

Do you really need Hunspell? You might want to consider using the built-in spellchecker on Android.
