I have translated a project in CyanogenMod (the Email app) to Hebrew by adding a values-he folder, and compiled the entire repository (make). I have made sure that the full languages make file includes the Hebrew language.
However, when I loaded the update zip to the phone and switched the language to Hebrew, I still received the English strings. I'm pretty sure I am missing a step.
Any idea, please?
EDIT: Again, my phone supports Hebrew - as evident by other applications that do switch locale according to the values-he folder content. It's just for the Email application that it doesn't work.
According to ISO 639, he is the correct ISO 639-1 code for the hebrew language. Whereas iw was deprecated back in 1989. The reason some Android devices use iw is thanks to Sun, you can read the details.
Devices like the Nexus S, sold in the US use iw. If you go to Israel and check the locale on a phone sold there (Galaxy S for example), the language will most likely be reported as "He IL N/A עברית", so it correctly uses he and not the deprecated iw.
If you want to support this fully, you should include both variations to account for these differences.
