How to translate
We use Crowdin as our translation system. To contribute with translations, create an account there, click the desired language and apply as translator. Once you are accepted, you can click through the various files and suggest translations.
Difference between LineageOS and LineageOS AOSP
On Crowdin you will notice two different projects:
LineageOSproject contains translations for LineageOS’ additional features and applications for languages supported by AOSP.
LineageOS AOSPproject is for languages not part of the upstream Android sources. It contains the strings for LineageOS’ features and additions but will also allow for translation of the rest of the OS.
My language is not there and I have checked several times
You seem to speak a language which nobody else does… or there has just been the lack of someone willing to provide support. Contact one of the managers so we can support you by adding your language as well.
I have translated a lot, how do I get these to my device now?
There is (or should be) at least one proofreader for each language (you can apply, if not). Proofreaders will look through the strings and validate those which they think are fitting the context and are of a high-enough quality. In the event that you do not see an active review or acceptance of your (or alternative) suggestions, you can contact one of the proofreaders via the sidebar on the right. To do so, simply type “@” followed by the name and then add the message (e.g. “@NameHere: Please look through my translations on this file”).
After the strings have been validated, a scripted job is run (by one of the Managers to import the strings to Gerrit. After a successful test build they get merged to source code and will be part of every new official build.
Correcting wrong strings
Sometimes you will notice translated strings which seem to be slightly different from what you’d expect or simply wrong. There are various reasons to how this can happen, but still, the only relevant thing is how to improve the translation. Just suggest your translation like you would do for any untranslated string. After saving it you will have the possibility to “Notify the proofreader”.
There is no guarantee the original strings you want to translate are perfect. If you notice an issue there, use the side bar and mark the field “issue”, then type some info on what you think is wrong. If the mistake is only minor, correct this error in your translation, and submit it.
