I have made a couple of functional Android Apps and now I want to make
my own virtual keyboard, to substitute the default keyboard (similar
to TouchPal). I have found absolutely no information to guide me in
this process. The reference documentation does seem to be in order
and useful (Keyboard, KeyboardView, ...) but my main question is: Do I
start just like any other app? Is it an Activity?
TouchPal for example doesn't appear in my applications menu, it has to
be activated in locale preferences and then selected when introducing
text. How do I do that?
Is there any open source virtual keyboard I can check out?
Thanks for any help!
