Patch: add ctrl and alt-gr modifiers for bluetooth/hardware kbd

GoogleCodeExporter commented 8 years ago

Hey,

on my Samsung Galaxy Tab, I operate a foldable bluetooth keyboard (CHINFAI 
Silikon Smart) as well as the Samsung-specific dockable hardware keyboard 
(ECR-K10D, attached via internal UART). 

Both are QWERTZ layout - that's the German kbd standard. I also operate a 
parallel loop-disk-based Debian on that senior-size phone. I like to do some 
programming - e.g. use the "joe" editor on the command line. The attached 
ConnectBot patch is essential for that. It summarizes my changes to ConnectBot 
(current Git). 

Notes:

* Patch is Signed-off-by sven-ola-aet-gmx-de
  I would appreciate if it finds it's way in.

* Ctrl modifier works both BT and stock Samsung Kbd.

* AltGr Keys are hardcoded German layout. The Android
  "event.getUnicodeChar(curMetaState)" result does not
  change if called with META_ALT_ON or META_ALT_RIGHT_ON
  as I would expect. Without these, no {[]}\@|~ keys for
  me. Maybe the missing alt-gr-translation has something
  to do with the Samsung-IME - I'not sure about that. Other
  IME (e.g. Swype or Gingerbread-Keyboard) do not translate
  to German layout at all (e.g. got "y" when I press "z-key").

* To get Alt-Gr as well as the "official" ctrl scancodes
  that are not avail on that Samsung Kbd, I hacked in a small
  kernel module that changes some keys. This is attached 
  as reference (both source and binary).

Tests like:

+           if (keyCode == KeyEvent.KEYCODE_UNKNOWN && key == 0 && scanCode == 1)
+               key = 0x1B; // Esc

don't seem too robust. For example, with my external USB keyboard, Esc gives 
KeyEvent.KEYCODE_BACK. However, scan is the same - 1, and this appears to be 
pretty standard scancode (Linux kernel knows it the same way).

So, proper way to handle scancodes appears to be let existing ConnectBot key 
processing to try to do its job, and the very end, instead of reporting key as 
unprocessed, to check scancodes (and only scancodes) and process them. At least 
that's how I do it in my fork,
