Hi!
I'm also injecting keys, but I have developed a custom keyboard using
/dev/uinput. I need to translate unicode keys to android key events and I'm
using the getEvents method on KeyCharacterMap class like you guys. I'm also
facing the same problem, that accented characters can not be inserted --
getEvents returns no events for such character arrays. Even if character
array contains regular characters and then an accented character, nothing
is returned.
Is there something wrong with how we're using getEvents or perhaps some
other method that would return the required KeyEvents?
Regards,
Miha
