Dictionary creation

To create or update a dictionary for your language, you can use this tool. You will need a wordlist, as described here. The output .dict file must be put in res/raw, and its wordlist in dictionaries.

For your dictionary to be merged into OpenBoard, you must provide the wordlist you used, as well as its license if any.

Code contribution

Getting started

OpenBoard project is based on Gradle and Android Gradle Plugin. To get started, you'll just need to install Android Studio, and import project 'from Version Control / Git / Github' by providing this git repository URL (or git SSH URL).

Once everything got setted up correctly, you're ready to go !


OpenBoard is a complex application, when contributing, you must take a step back and make sure your contribution :

  • Uses already in-place mechanism and take advantage of them. In other terms, does not reinvent the wheel or uses shortcuts that could alter the consistency of the existing code.
  • Has the lowest footprint possible. OpenBoard code has been written by android experts (AOSP/Google engineers). It has been tested and runned on millions of devices. Thus, existing code will always be safer than new code. The less we alter existing code, the more OpenBoard will stay stable. Especially in the input logic scope.
  • Does not bring any non-free code or proprietary binary blobs. This also applies to code/binaries with unknown licenses. Make sure you do not introduce any closed-source library from Google.
  • Complies with the user privacy principle OpenBoard follows.

In addition to previous elements, OpenBoard must stick to F-Droid inclusion guidelines.

Current TODO list

In no particular order, here is the non-exhaustive list of known wanted features :

  • Updated emoji support

  • Emoji search
  • Emoji variant saving
  • Glide typing


Edit keyboards content

Keyboards content is often a complex concatenation of data from global to specific locales. For example, additional keys of a given key, also known as 'more keys' in code, are determined by concatenating infos from : common additional keys for a layout (eg. numbers), global locale (eg. common symbols) and specific locale (eg. accents or specific letters).

To edit these infos, you'll need to generate the file. To do so :

  1. Make your modifications in tools/make-keyboard-text/src/main/resources/values-YOUR LOCALE.
  2. Generate the new version of by running Gradle task 'makeText' :
    ./gradlew tools:make-keyboard-text:makeText

Update emojis

See make-emoji-keys tool README.
