This adds dictionary-based spell checking to the keyboard. The keyboard looks at the word being typed and matches it against a dictionary to either complete the rest of the word or find alternative spellings.
The core of this feature is implemented in cdict, which is included as a
submodule in vendor/cidct.
Cdict is developped at https://github.com/Julow/cdict
The dictionaries are hosted at https://github.com/Julow/Unexpected-Keyboard-dictionaries/
The wordlists used to build the dictionaries are the same ones used by
HeliBoard from https://codeberg.org/Helium314/aosp-dictionaries
- Add an activity accessible from the launcher app that lists available
dictionaries with a download button.
The DictionaryListView view shows the list of available dictionaries and
handles downloading and installing them.
- The Dictionaries class manages installed dictionaries. Dictionaries are
installed as individual files into the app's private directory.
- Available dictionaries are listed in dictionaries.xml, which is generated
when building Unexpected-Keyboard-dictionaries.
method.xml mentions the dictionary name for each locales.
