Hi,
In conjunction with what I was trying to do here - http://forum.xda-developers.com/showthread.php?t=1333674 ,
I modified the keylayout in /system/usr/keylayout/AVRCP.kl so that the keycode that was earlier assigned to MEDIA_NEXT is now assigned to MEDIA_PLAY_PAUSE.
From
Code:
key 200 MEDIA_PLAY_PAUSE WAKE
key 201 MEDIA_PLAY_PAUSE WAKE
key 166 MEDIA_STOP WAKE
key 163 MEDIA_NEXT WAKE
key 165 MEDIA_PREVIOUS WAKE
key 168 MEDIA_REWIND WAKE
key 208 MEDIA_FAST_FORWARD WAKE
to
Code:
key 200 MEDIA_PLAY_PAUSE WAKE
key 201 MEDIA_PLAY_PAUSE WAKE
key 166 MEDIA_STOP WAKE
key 163 MEDIA_PLAY_PAUSE WAKE
key 165 MEDIA_PLAY_PAUSE WAKE
key 168 MEDIA_REWIND WAKE
key 208 MEDIA_FAST_FORWARD WAKE
For good measure, I also changed the MEDIA_PREVIOUS to MEDIA_PLAY_PAUSE.
Trouble is, this fix isnt working. Am I doing something wrong? Is it reading the configuration from elsewhere?
Meanwhile, the default headset is working fine with these settings as well. I could really use some help here

We all know that the physical keys mapped for Android are less than ideal--so let's work together to build a better Vogue key map, that we can ultimately customize the layout to our individual likings.
Here is an excellent link detailing information regarding Key Input and the Key Map--if nothing else, glaze over this quickly: http://www.kandroid.org/android_pdk/keymaps_keyboard_input.html
Android KeyMaps are stored in /system/usr/keylayout. On your particular build, you'll probably see a number of .kl files: AVRCP.kl, h2w_headset.kl, qwerty.kl, sapphire-keypad.kl, trout-keypad.kl, etc. For our purposes, disregard all of them except qwerty.kl. If Android can find no other .kl file, it will default to qwerty.kl. You can (for example) delete all of the other .kl files, and your phone will function exactly the same based on qwerty.kl.
If you examine your qwerty.kl, it will look very similar to the KeyMap from the link above. It follows this format:
SCANCODE KEYCODE [FLAGS]
Here is, for example, my qwerty.kl as pulled from Plemen's 1.6 AOSP build:

When a button is pressed, it sends a SCANCODE to Android, which is interpretted and this file defines the corresponding action--back, volume up, end, camera, etc.--as well as the FLAGS that code may have, such as "WAKE", which means that button can then wake the device from sleep.
What we need is to map the button single-press and long-presses on our Vogue and identify the SCANCODES. With them, we can write our own .kl file, completely customized for us.
Currently, getting the SCANCODES seems to be the roadblock. I've tried "GetKeys" from the terminal without any luck. In the research I've done so far, it appears it may require some native C code to interpret system input and print it back out.
Please contribute and feel free to dig away in an effort to accelerate this project. Once this is done, it's one more item checked off for Android development--and it should be portable to all versions (1.5, 1.6, 2.0, 2.1, etc.)
Lastly, while I believe everything I've cited to be true, I may be incorrect--please correct me if I am.
this is something we've addressed before a few times, and have already changed the default keymap to what it is now.
Currently the keymap is set by the kernel, not by the userspace. check the kernel git and you should be able to find what you're looking for.
In case someone's still trying to find out which key does which scancode (or rather key number in the .kl files): Just use "getevent" in the terminal or ADB.
Second column of numbers is "key number" in hex.
Hi,
I'm looking to something like this to a bluetooth keyboard. How to implement deadkeys?
The section at the end of this post maps an extrnal keyboard to dvorak.
Note, the escape key sends escape instead of going back as in the original
qweryt layout. I have not figured out how to send the Ctrl modifier key.
If someone can figure out how to put that in the position of the Cap Lock key,
that would be great.
This may help:
developer.android.com/reference/android/view/KeyEvent.html
To make this work, copy the keycodes into a file, say dvorak.kl, then make backups
of your qwerty layout and copy:
Code:
su
cp /system/usr/keylayout/en_us.kl /system/usr/keylayout/en_us_backup.kl
cp dvorak.kl /system/usr/keylayout/en_us.kl
cp /system/usr/keylayout/gpio-keys.kl /system/usr/keylayout/gpio-keys_backup.kl
cp dvorak.kl /system/usr/keylayout/gpio-keys.kl
Then select English (us) from your Settings-> Language and keyboard-> Select external keyboard layout menu.
Don't know how to make dvorak show up as an option.

Use the RE Explorer (remember change the folder read-only permissions to read and write) into the / system / usr / keylayout folder, in qwerty.kl file, add a few lines of code:
key 113 MUTE
key 163 MEDIA_NEXT
key 164 MEDIA_PLAY_PAUSE
key 165 MEDIA_PREVIOUS
key 226 HEADSETHOOK WAKE
key 231 CALL WAKE_DROPPED
Now it can control music playing!
One click- play, pause music, answer/ end the call
long press- play the next music
double click- play the previous music
Doesn't work on Oxygen how can check what button code a button have?

Sorry, I have no idea about Oxygen rom. Try to fetch offcial conduction from the Oxygen group.
Okay thanks!

Are you sure it isn't key 226 HEADSETHOOK WAKE without a space between oo and k?

This works on Oxygen too, thanks dude! =D

Ur, I'm sorry. There is no space between oo and K.
have anyone tried them on stock rom ?
My headset button worked fine on stock atleast on 136. But this may add some functionality like mute mic (I dont remember that function on stock). Anyway you should find a .kl file in that folder on stock too.

Hi All,
So basically I flashed another firmware on my box and it works except the remote.
The buttons on the remote are messed up but work but some buttons aren't recognised.
However, i found the file that is responsible for the mapping of the buttons.
The file is located in /system/usr/keylayout/sun7i-ir.kl
So opening the file sun7i-ir.kl reveals this:
key 0x57 POWER WAKE
key 0x52 MEDIA_PLAY_PAUSE
#key 43 MEDIA_STOP
#key 60 MEDIA_PREVIOUS
#key 79 MEDIA_NEXT

key 0x5b MUTE
#key 0x0f PROG_RED
#key 0x4c PROG_GREEN
#key 31 PROG_YELLOW
key 0x4f SETTINGS
I found other configurations but none follows the same as my remote.
So I have attached an image of my remote so if anyone has the same remote or a similar one with the same buttons please extract your sun7i-ir.kl and send it to me.
Many thanks

Did you find anything useful?
I want to know what Prog_green and etc is?
The "color" buttons are commented out there, but you don't have any "color" buttons anyway.
Step one: Connect your remote and look at logcat to double check that it is loading the .kl file that you think it is.
Step two: Determine which keys do not work.
Step three: Android does lots of goofiness with MEDIA_XYZ keys, they go through MediaSessionServer.
The "color" keys are unlabeled keys on TV style remotes.
Hi All,
I have a ac8317 head unit which doesn't have the hardware BACK button.
Since I don't user the equalizer, I was wondering if it could be possible to update the unit keymap to use the EQ button as BACK button.
Anyone knows which parameter needs to be changed in order to do so?
