My HD2 "Frankenphone" (it's built from no less than 3 other HD2's) has no working hardware keys on the front of the phone. The volume keys, however, do still work. I therefore want to cook a rom based on an existing one that has Volume up/down mapped to HOME/Back.
Furthermore, I was wondering if I could somehow get the MENU button implemented as well. I understand that this is not possible through the SDK, but perhaps it can be done by writing native C code. E.g. a longpress Volume-up could be menu, a long-press Volume-down could be search.
I'm not asking for someone to do this for me, I'd like to do this myself. What I'm looking for are a few quick pointers to how to start this endeavor. I have previous experience cooking custom roms using toolchains under linux, and also experience writing C (non-gui) code under linux. So useful pointers would be :
* Where can I find the key mappings? I suppose this is part of the kernel/user space?
* How would I go about implementing the long-press feature? Or can you hint towards another possible solution that does not involve the front hardware keys (touchscreen snooping for gestures? accellerometer? Any other sensor?)
Take a look here:
http://source.android.com/porting/keymaps_keyboard_input.html
Hope that helps.
One thing I do in most builds is change my call key to a search key.

Awesome, thanks! That worked like a charm. Mounted the system.ext2 loopback, patched the keys, and tadaah, working home + back. That at least makes the phone usable again.
Can anyone recommend a solution to get a working MENU action? It looks like long-press back is handled by apps individually (e.g. in the browser it will show a history), while long-press home displays a task switcher. I could live with long-press back being handled by android itself to implement the menu function.
(edit) looks like this is possible, e.g. here it mentions "including some special features to support the virtual hard keys that are appearing on recent devices such as Droid." Now how did they do that?
So I want to remap the hardware buttons, but ran into some issues:
google searches say to edit the /system/usr/keylayout/sec_touchkey.kl (for previous galaxy devices), but this file is mysteriously absent on my stock rooted s4.
I tried other files in this /system/usr/keylayout/ folder; atmel_mxt_ts.kl seemed promising in its content:
Code:
key 139 MENU
key 102 HOME
key 158 BACK
key 217 SEARCH
Changing these, however, did nothing.
Am I searching in the right place, just in the wrong files? Is there a file chmod permission I might be missing?
I think there was also a jar file (android.policy.jar?) I'd have to decompile if I wanted to change the long-press actions for these buttons?
Can I override the double-press home button to do something different than s-voice? (I know I can disable the app itself)
Thanks!
disable the button

I was also looking all over for this. Did what you did and also other. kl in the system usr no change also . Using 3minit mod. Wanted to disable the hardware button as having the navigation bar and therefore now having two back button.
Anyone here with any idea to share?

i dont have an S4 at the moment and i cant remember the exact file name but its under system/usr/keylayout looking through a rom file i think its gpio-keys.kl just mount the folder as read/write then comment out the lines you dont want using # then reboot
what did you do to enable the navbar when i had i was using an S4 last week the only way i could get it working was with an AOSP rom which meant no samsung camera or IR
*edit i should add that this was on the verizon S4
success disable hardware back button
I finally managed to disable the button. Its in system/usr/generic.kl . Place# infront of key 159 back and reboot. Done.
Got navigation bar using 3minit setting and mod.
If it works for you hitting the Thanks button will help. Cheers

Good to know, but my use case is a little different... I'm hoping to swap/ change the soft keys, not disable.
But if generic.kl worked for you, that's a good place for me to start. Will play around and post back if I can swap the menu/back button, hopefully the long press options as well. Ideally I want to move a lot of things around, (long press home for gnow, back to recent, long for menu, menu to back) but we'll see.
I'm on stock rooted, which is why I still need functionality
based on how I see it. I think it could be done
I will try it out if I could swap the menu and home like how you wanted. But you definitely need to be rooted first to edit the files
tried it changing key 139 MENU with BACK. saved reboot with success. Menu function swap to back function.
rem you got to be rooted for this to work. ..

Is a long press registered as a different key for mapping purposed?
Like menu button is 001 but long press menu is 002?
Ultimately I'd like to be able to make a long press on the home button turn the screen off. That's my end goal with that question.

In the generic.kl file, just change the labels to what you want. For instnace, where it says 117 VOLUME_UP WAKE (thats just an example) remove the volume_up and put MENU or BACK or whatever you want there.

The system interupts the key down press, it then launches a post delayed runnable when you press down, if the key is pressed down for the length of that post delayed, then essentially "long press" has been executed. The runnable then consumes the the original key press to prevent the key from executing.

If you are trying to do it via the system. Meaning overriding system button presses, then you will have to edit the smali code. I believe the method is interceptKeyBeforeQueing or something like that.

You are in the wrong place, bud. Please ask questions like this in the q and a forum. This is a development forum for development related discussion.
And do try to be a tad calmer when posting. There are tons of people who will be happy to help. But the aggressive tone of your post will prevent many people from wanting to assist.
Also...really? Its the arrow to the right of the home button on the bottom right of the phone.

Another potentially useful resource is this list of keycodes:

I haven't had time to play much with this stuff yet, but I DID try the KeynrTracker.apk listed here, however it does not seem to register any of the long presses, leaving us only with menubutton as 139 and back as 158. It could have something to do with the way this app is designed, or in the way Samsung is firing these button presses.
More to come.

Anyone know if it is possible to swap the mapping of the home/back buttons? I use the back button more often than the home button and find the location of the home button easier to reach in general. I realize I can't change the actual hardware icon ... looking for a software fix.

You can try the "Xposed Additions" module that remaps hardware keys but not positive if it will work, never used it on this phone.

There are some options that can help with this in the ViperMAX ROM:
1. In tweaks you can set custom mappings for short press, double press, long press and swipe action for the home hardware key. The same can be done for the back key (except for the swipe action, if I'm not mistaken).
2. You can enable PIE, which basically allows you to slide your finger from the side of the screen to pop-up customizable software buttons on the screen. I use this for the same reason you describe (to make my most common actions easily accessible with my right thumb). In-fact I use PIE to pop-up software buttons to do things like "back", "pull down notifications" and "home"...
If you take advantage of those tweaks, it is easily enough to suite your needs and more.

Yes, it possible software wise. I'll pm how to. File explorer needed with root access.
It can be done with Sence or Aosp, stock or custom ROMs. I edit this ever device I have to suit my needs. I like running full screen, no status bar nor navigation bar. One reason I like my Max. Full 5.9 viewing area.

Could you PM me with your solution? Thanks.
This guide is for the Note 3 Neo and should work on all variants.
If you're looking at this thread then you should have noticed that the Menu key on @FireLord 's CM12.1 is mapped to MENU and you can't change it from Buttons in Settings since it only has Power Button, Recents Button, Volume Button and Home button and no Menu Button.
Of course, there are a bunch of Xposed Modules such as MenuBegone available to do the same but if you'd rather not install anything or if you just like to mess with your phone then this is the guide to follow
So here's what you to do make your Menu key function as a Recent's key.
Download any Root Brower (I'd suggest the one included in Rom Toolbox)
Navigate to /system/usr/keylayout/Generic.kl
Open the File Generic.kl as a text file
Look for key 139 MENU in the list
Replace MENU with APP_SWITCH
Save and Reboot
Now your Menu key will function as a Recents Key and you'll also be able to change what tapping it and long-pressing it does through Buttons In Settings.
Thanks for the info.

I've found temporary solution tbh, but it kinda weird. the softkey also vibrate when the screen is off.
http://forum.xda-developers.com/showthread.php?t=2152355
still searching for another solution tho.
Hey guys, got a quick question. I have a Leagoo M8 which uses softkeys for navigation. Now normally this is OK, but for some crazy reason Leagoo decided that it would be a great idea to completely change their actions. Currently they have the following actions:
Tap Recents button = Menu
Long Press Recents button = Search
Long Press Home button = Recents
Typically softkeys have the following actions:
Tap Recents button = Recents
Long Press Recents button = Nothing, or Menu
Long Press Home button = Assistant
As someone who has used nexus and other devices in the past, this behaviour is really annoying. I don't want to have to reply on Xposed or Root as there are apps which I want to run that do not allow root, so I'd like to change this on a ROM level.
The ROM I am using is a debloated stock Android 6.0 ROM which is mostly stock Android, which is available here: https://forum.xda-developers.com/android/development/6-0-lazy-s-debloated-rom-leagoo-m8-t3574816
I found this thread that explains how to change the look and feel of softkeys, but am I right in saying that this doesn't apply to changing button actions? A long time ago I remember that there used to be some XML files that could be edited which changed various button actions, but that would have been for Android 4.4, and I'm not sure how much different Android 6.0 is. If anyone would be able to point me in the right direction that would be super appreciated :good:

Ah, interesting. I've tried editing the config files with a text editor in the past and never had too much success, but something worth trying :good:
Alright, quick update. I updated Generic.kl but it doesn't seem to have any effect. I think it is only for physical keyboards, whist the Leagoo has softkeys. Any other ideas?
