Easy guidelines for key remapping(Inlc +FN,+Shift,only HEX editor needed)

To change ANY key you want (including +FN, +Shift, +FN+Shift).
When a key is pressed:
1.You pressed a hardware key, the system get a keycode(scancode):
(you can use "adb shell getevent" command to get the scancode)
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
2.The action related to the code is defined in “.kl” files in “/system/usr/keylayout/” according to your language:
3.Then those action such as FUNC_3/MENU/etc. can be found in “KeycodeLabels.h”:
(Thanks to teferi's github at https://github.com/aglasgall/g2-keymap)
4.Again the code “99” is defined in “*.kcm.bin” file in “/system/usr/keychars/”:
Column 0 is related to the code above.
(in this picture,for example, we know when we press Z, we got "z", Shift + z = "Z", FN + z = "<" , Shift + FN + z = "<". and yes, I modified it to get < and > key on my phone, haha)
Some special code for use in built-in Touch Input ONLY(except Tab):
Code:
09 00 = TAB
01 EF = SYM
02 EF = useful URL pre/surfix
03 EF = ".com"
04 EF = "www."
In short, there are TWO places we can change our keymapping:
1. Text edit the .kl file to change the keycode of a particular scancode
2. Hex edit the .kbm.bin file to change the action of a particular key
For reference you can open .kl or .kbm.bin files of other langs, and Google their keyboard's real picture
In face there are some obvious key(e.g. 0 to 9, A to Z ), you know where to modify without looking for the scancode/keycode/etc..
So, either ".com" key or "Tab" key or both, up to you MAKE IT YOUR PERSONAL KEYBOARD NOW!
According to different DZ from different country, your corresponding keymap files may be different. make sure you know which file to modify first!!!
For those Hong Kong and Taiwan DZ users who wanna fix the "中/英"(lang switch)key in WWE ROMs can try this method.

Should "KeyCharacterMap.h" perhaps read "KeycodeLabels.h"?
Btw, I am going to nominate you to the Nobel prize in keyboard mapping for this.
Many thanks!

ah, yes, should be "KeycodeLabels.h", thx for reminding.
One more thing, I just find that in third party IME, the "Shift+FN" doesn't work, it works only under "Touch Input".

I'm trying to map the keys of a Bluetooth numeric keypad that I have linked via Cyanogenmod. The problem that I'm having is that for all keys except 7, 8, and 9, the scancode doesn't have a keycode assigned to it (discovered using KeyTest from github . com/chrisboyle/keytest/downloads). All keys report a scancode from dec(71-82), but they all have a keycode of 0. The adb shell getevent command verified that the keys do indeed generate a scancode in hex.
I have been trying to get the setkeycodes command to work (source found from groups.google . com/group/android-x86/browse_thread/thread/f24c7636da5dd124 ), but it keeps giving the error of:
KDSETKEYCODE: Invalid argument
failed to set SCANCODE 4c to KEYCODE 13
Much Googling has given me zero results as to how to fix that error, and no keycode I have tried has worked.
SO . . . can you either tell me how setkeycodes is supposed to work, or will your hex solution work as well? Can I add a line to the *.kcm.bin file, or do I need to recompile things?
Thanks!!!
EDIT: I'm actually on an EVO using CM7 RC2

In italian version we have è,ò,à,ù,ì after pressing the letter, fn, space. Do you know where this is set? Because I've seen that many roms don't have it and I wanted to change.

I quote it;
in italian FN+Space make "à.è.ì.ò", but in some rom doesn't work.

I think the problem lies elsewhere, and it isn't correlate to keymaps.
Let me explain how FN+SPACE works for italian keyboard:
1. you type a vowel, e.g. a
2. Then you press FN+SPACE and a become à
3. press again FN+SPACE and à become á
this works only if the blinking bar | is right after the vowel.
It's a two steps procedure and it can be applied to every vowel already written.
Also I checked the vision-keypad-ita.kcm.bin of a rom where the italian keyboard works and compared to the file in the rom where there is no italian keyboard. I found they are the same exact file.
Futhermore I checked it in the hex editor and for the SPACE key there is only the space character assigned in every possible combination.
I think FN+SPACE launch a function that is missing in custom rom.
For istance, in my VIRTUOUS Unity rom FN+SPACE combo launchs the hardware keyboard setting.
The problem is not the keyslayout, but the function that it calls.

So maybe I'm totally not understanding the purpose of this tool, but is there a way to set a custom process to launch when I press a key? IE: set a key to launch Handcent's Quick Compose function?

Anyone have an idea how to get a Control key? I need to remap the keyboard on my Droid 3 and have a dedicated Ctrl key.
I assume edit probably the /system/usr/keylayout/qwerty.kl and use something like:
Code:
key 16 CONTROL_LEFT WAKE_DROPPED
but not sure about the "CONTROL_LEFT" part, or should it be "CTRL_LEFT" or something like that.
Have never messed with Android... and so have nothing to base it on...
EDIT:
Also, I'm trying to get the codes for all the pressed keys on the physical keyboard via getevent, run directly on the device, not through the SDK, and once getevent is started, I get tons of output, but it doesn't seem to be reacting to the keyboard, i.e. pressing `a', the `a' gets echoed directly in the terminal, and no apparent getevent event is triggered... How to do that?

Nope, that's not the purpose of this guide.
But does anyone know is there any way to have a button work as a DPAD button and a character button at the same time? Ie. when I press a button normally I want it to perform DPAD_UP command but when I fn-press it I want it to do a symbol. At the moment if the key is a DPAD key and you hold down fn or shift and press it nothing happens.

[Q] Passing to Android from Nook

I have a nook simple touch reader, I installed android with a sd card following these instructions
--------------------------------------------------------
For Windows users:
Run WinImage.exe (Right click, Run as Administrator)
Select Disk from the menu and select "Restore Virtual Hard Disk Image...".
Select your SDCard from the list and click OK.
In the Open dialog box select "All Files" in the lower right file type box, browse to nookhoney.img, select, and click Open.
--------------------------------------------------------
When I rebooted it was a screen that allowed me to choose two options, one was "ADW"(I suppose that is android) and "Home" (usual nook). I selected "Home" and made a tick on the box to make it default. Now I do not know how to go to android from the nook "Home".
Could you help me, please?

Don't know about nookhoney.img - I used MinimalTouch.
I have a faint symbol on the right hand of the screen. Touching the symbol makes a faint menu pop up.

@niaosan: That's Button Savior, it will get you back to the Launcher, but won't change the preference.
@genoxygen: I'm not familiar with nookhoney.img
Some folks have Nook Touch Tools or Nook Color Tools which have functions for changing activity preferences.
Do you have ADB to your Nook?
I just do this stuff by hand.
Code:
adb pull /data/system/packages.xml
Then edit the XML taking the "guts" out of <preferred-activities>
That is, deleting the lines between, but leave <preferred-activities> and </preferred-activities> alone.
Code:
adb push packages.xml /data/system/

Are you sure you are speaking about the Nook Simple Touch (black and white ebook reader), and not about the Nook Color or the Nook Tablet? nookhoney is for the Nook Color. They are supported in different sub-forums.

My nook is the "simple touch reader" and the software android software is touchnooter-2-1-31.
Sorry about the confussion.
-------------------------------------------------------
I observed I have a button on the screen, to right, I pressed that button, and there are 5 options.
-three cercles
when pressing them, it shows me another menu, to choose a telephone, a camera and a seacrh option.
-arrow
Superuser Request. Button Savior is requesting Superuser access.
I pressed Allow, but I do not know what is its utility.
-four squares
- a house
goes to nook home
- a power down button
does not do nothing
-------------------------------------------------------
I pressed all those button but none of them takes me to android. What could I do next?
Did I installed correctly android to my device with these instructions?
--------------------------------------------------------
For Windows users:
Run WinImage.exe (Right click, Run as Administrator)
Select Disk from the menu and select "Restore Virtual Hard Disk Image...".
Select your SDCard from the list and click OK.
In the Open dialog box select "All Files" in the lower right file type box, browse to touchnooter-2-1-31.img, select, and click Open.
--------------------------------------------------------

"House" is going to Nook stock Home because you selected the wrong activity.
My advice is as above or use one of the "Nook Tools".

By the way, you didn't install android, because it was already in there. You were allowed to bypass the restricted Barnes&Noble reader part and run your STR as a full android e-reader/tablet.

509A ndivTi
I do not know how to use adb, although I have it installed on my Windows OS...
------------------
What could I do? Should i...?
- Restore my nook firmware, installing n2T-Recovery_0.1.rar http://forum.xda-developers.com/showthread.php?t=1289233
- Install touchnooter-2-1-31
- Choose "adk" instead of "home", should I make it default or not? If made default, can I go easily to nook "home"? Or there will be the same problem like the one I had?

You can always get back to the Nook Home page (unless you deleted it like I did ).
The adb you want is in the Android SDK. http://developer.android.com/sdk/installing.html
You can use it over Wifi or USB. The USB needs drivers on your desktop though.
The file is adb.exe
It should be in something like C:\Program Files\Android\SDK\platform-tools
Code:
adb connect 192.168.1.27 [i]or whatever[/i]
adb shell
ls

Thank you so much. Finally I did it.

Internal memory issue

Guys,
When my wife plugs her GS4 on her computer it says "486MB free of 9.24GB"
When I go to settings and storage, the system is alocating almost 7GB to run certain applications. This cannot be right. Any thoughts?

Anyone?

System Memory is about 7GB in lollipop that's correct. This is because of ART run-time in lollipop. Please clear the cache data I can see this is 3.36 GB

I did this but the cached data is still the same
Turn off phone
Remove the battery and reinsert.
Hold down the Home and Volume Up keys
Press and hold the Power button while still holding the other keys.
As soon as you see the Samsung logo, release all keys/buttons.
Press on the Volume Down to scroll down to Wipe Cache Partition.
Press the Power button to select it.
Press the Volume down button to highlight "Yes" and press the Power Button to select it.
Wait for a few minutes for the phone to clear the data.
Then press the Power button to select reboot system now.
Wait for your phone to reboot.

You can simply tap on the cache data in the same window you attached the screenshot ..it will give you option to clear cache .. then recheck storage ..repeat 2-3 times then cache data will be too less or will not show even ..
To compensate memory I would recommend to buy a class 10 memory card for this phone ..this supports upto 64 GB ..but 32GB or less one should not effect performance. .
If you are expert ..flash the latest Panama (unbranded) rom ..this is much stable ..disable the nfc ..

[HACK] [PLK-L01] Smart Key Remap (requires ROOT)

Do not attempt this if you do not know what you are doing, it could leave your phone unusable! - I am not responsible for your mistakes
If you like the SmartKey how it is, this is not for you, it will render the smartkey app useless until you change the settings back!
With that out of the way...
I listen to a lot of music via my phone (driving, work, etc.) I wanted the SmartKey to skip to the next track. As I see it, that's not possible with the smartkey app, just basic app launching.. (someone please correct me if I'm wrong!)
This should work with a number of system functions, called by key presses, but I'll focus on the one I wanted. See the bottom of this post for others..
You need ROOT! I did all of the following via the very excellent "root explorer", but can be done in the shell, adb, or your favourite app that allows such things as editing /system files.
Let's Go!
locate and backup the following file: (root explorer does auto-backup on edit/save)
Code:
/system/usr/keylayout/Generic.kl
edit this /system/usr/keylayout/Generic.kl file
half way down you will see :
Code:
[B]key 194 SMARTKEY[/B]
place a # in front of this line (thus removing the SMARTKEY app functionality from this key press. Also gives us an easy way to undo.)
under the SMARTKEY line, add a new line with the same keybind "key 194" followed by the function required, in my case "MEDIA_NEXT":
Code:
#key 194 SMARTKEY
key 194 MEDIA_NEXT
Save and close the file
Restart phone
Done
The bonus is that a double click will move to next album :victory:
---------------------
To Revert Back
edit the file again
remove the line you added
remove the hash, leaving the file as it was:
Code:
key 194 SMARTKEY
(or replace it with the backup!)
Restart the phone
Done​---------------------
There are a number of useful media functions that can be mapped:
Code:
MEDIA_PLAY
MEDIA_PAUSE
MEDIA_FAST_FORWARD
MEDIA_NEXT
MEDIA_STOP
MEDIA_PREVIOUS
MEDIA_REWIND
VOLUME_MUTE
---------------------
There are other non-media functions, all listed in the file you've been editing.. Play with it, if you're brave. Just remember not to wipe out the whole file or none of you buttons will work!
It should also work with other Honor 7 variants, but I cannot guarantee that the key-bind number is the same (or even if it's the same file!)
Cheers.

How to enable Software Navigation Buttons ?

Hello,
Is there a way to enable, Software navigation buttons on Mi A1.
As the hardware capacitive keys, are positioned in chinese format, "back key" is on right, where as it should be on left.

Add this line to build.prop and reboot:
qemu.hw.mainkeys=0

Could it be possible in future to swap back and multitasking buttons and turn off the button light?

back there when I use Oneplus you have to edit Generic.kl file located at system/usr/keylayout
since Oneplus have stock AOSP based ROM just like Mi A1, it should be the same, or similar.

anyone knows how to turn off the light on the a1?

No. It just enables soft keys. To disable hw keys
Using root explorer Go to system/usr/keylayout
edit the ft5435_ts.kl and add # before menu home and back..save and reboot..both light and hw keys will be disabled..

Found an app on play store to swap back and recent key. Upgrade to pro is needed. I tried the app and it works great but ram consumed is above 200mb. Button mapper.

This can be achieved from GravityBox( xposed module ) under 'Navigation bar Tweaks' enable master switch and tick 'Enable navigation bar' check box and restart your device.
