WARNING! THIS PROFILE IS IN BETA. DO NOT INSTALL UNTIL YOU HAVE READ BELOW!
Beta
When creating this profile I experienced bootloops and splash-screen freezes. If you are not comfortable with how to restore your device from these states, then please wait until it has been thoroughly tested before applying the profiles and tasks.
Testers
If there are any of you left after reading the above I was unable to totally identify what caused the crashes. I hope that through my own testing I have removed the probable causes, but I cannot promise. Read on if you’re still game and post below to let me know you’re in!

Theory
Have full media control using your device’s hardware buttons when the screen is off. Normal functionality restored when the screen is on.
Current Shortfalls/Work-in-progress
Fast reboot required to allow for system changes (15 second reboot).
- To my knowledge, system changes require this to take effect. Please tell me if you know different? As a consequence, the profiles take about 25 seconds from start to finish to activate and deactivate.
Hardware keys control media at all times, not just when the screen is off.
- A revert profile currently takes care of this, so it’s still more than usable.
Unable to configure hardware keys to only perform actions on long-hold
- I’m working on this, but I think it may be down to Gingerbread/kernel restrictions?
Unable to get trackpad click to perform an action
- Again, Gingerbread/kernel/ROM restrictions?
Ability to skip music folder commands unknown
- I’m working on this
Pop up menu tasks are ugly
- I’ll sort out a suitable background image and work out how to change the icons.
Preparation
This may look like another mammoth, ball-ache of a tutorial, but it’s pretty simple really – make yourself a coffee and by the time you’ve finished it, you’ll be done.
You must have full root read/write access.
1) Ensure you are running the latest version of busybox free from the Market. Even if your current ROM comes with it preinstalled, the Market version allows for this and will update it according. This is essential, as a probable cause of the bootloops I experienced. Reboot after updating it.
2) Install the Locale Execute Plugin free from the Market
3) Download Button Saviour Root free from the Market. We will be messing with the hardware keys, so if you lose control of them, this application will save you by displaying them on the screen. Have a play with this application and make sure you are fully versed with using it just in case.
4) Nandroid backup after you’ve done the above so you don’t have to reinstall everything again should things go wrong {We will be mounting the system for full write access}.
Installing and Customisation
Basically, we will be creating a file with the media controls in and asking Tasker to overwrite the existing file when we want to use it – simple.
Using a file explorer, create a folder within the sdcard/Tasker folder called ‘mediacon’. Within this folder, create another called ‘orig’. Navigate to
Code:
system/usr/keylayout/
Take a copy of the file bravo-keypad.kl (bravo will be replaced with your device name (unless you have a bravo!)). Paste it in the ‘mediacon’ folder you created. Paste another copy in the ‘orig’ folder. Open the file in the mediacon folder with a text editor on your phone (or alternatively copy/push it to your pc and view it there).
From the .zip file below, view the bravo-keypad.kl file on your pc using an application such as Notepad ++ (download free from here) or a simple text editor (although the layout may be a little confusing).
You’ll need to compare the two and see what the differences are. The most important additions to the bravo-keypad.kl to enable the media actions on the hardware keys are:
Code:
key 139 MENU WAKE_DROPPED
key 158 BACK
key 217 SEARCH
To:
Code:
key 139 MEDIA_PLAY_PAUSE WAKE
key 158 MEDIA_PREVIOUS WAKE
key 217 MEDIA_NEXT WAKE
The hardware key numbers and the remaining content of the file will no doubt be different from device to device, I assume it will also be different betweens ROMs and user settings too. You will need to preserve the remainder of the file.
Please can I ask you to post the contents of this file in ‘code’ tags if you can’t see that someone has done this for your device already. Could you also detail your ROM and Kernel. It will help others to quickly edit the file with the correct settings without scratching their heads too much – community spirit and all of that.
As you can see all we are doing is changing the three hardware buttons (menu, back and search) to perform media controls instead. You’ll need to edit the file in the ‘mediacon’ folder (either on your device or drag/push to your pc and then back again) to reflect this. Make sure you do not change the file in the ‘orig’ folder! Remember, your device may have different key numbers for the hardware buttons, this won’t matter, just edit the ones listed as menu, back and search and not the ones that have a # before them.
So, now you have your edited file done and your original file stored safely. We’re nearly there!
Install the profiles and tasks and make sure they are unchecked until you have edited them for your needs. The Tasker Media Control V1.zip folder contains the following two profiles:
MediaBoot
MediaControl
It contains the following 8 tasks:
ResetMedVar
MediaMenu
MediaContBoot
MediaContOff
MediaContOn
FastReboot
FastBootConfirm
ContState
The triggers for the tasks are:
Device Boot
Headset Plugged
If you currently have any other profiles that load music apps or perform other tasks when the headset is connected, please disable these.
Firstly, open the task MediaContOn. Click on action 4 (execute action) and select edit. You’ll see two mentions of the bravo-keypal.kl. Replace ‘bravo’ with your device name, or alternatively with whatever the original file was named in system/usr/keylayout/ (I assume it is your device name?). You’ll need to press the back button once you’re done.
Secondly, do exactly the same in the task MediaContOff.
Finally, open the task MediaContBoot and alter action number 2 to the music application you use (if you don’t use the stock android player).
That’s it! You’re done!
Terminal Command Information
There will be a number of terminal commands running, to copy and overwrite files which will mount the /system as read/write. This of course always has its risks, so ensure you have that nandroid backup just in case….
In the task FastReboot, there is the terminal command
Code:
Killall system_server
This command is not without its risks too, but it is the only way to avoid a full reboot in order to apply the system changes.
Running the task for the first time.
In the profiles and tasks, two variables are created:
%EARP – This is set to 2 when the headset is connected and 1 when it is disconnected. By removing the headset (%EARP =1), you will trigger the exit task which will begin to revert the media button changes.
%MEDIACONT – It was necessary to create this variable to avoid Tasker reacting to the headset plugged trigger after the reboot and wanting to start copying the files all over again. If %MEDIACONT = 2, Tasker will therefore know you are already controlling the hardware buttons and it will prevent the headset profile running again. The variable is changed to a value of 1, once the button controls are returned to normal. Simple hey…
When testing, sometimes these variables were showing the wrong value, due to the options to ‘cancel’ at various stages of the tasks. Before you connect your headset and run the profiles for the very first time only, you will need to open the task ResetMedVar and click on ‘test’. This will set both values to 1. At any point, if your variables go out of sync, you can repeat this exercise so the headset connected/disconnected will trigger the profile/exit task accordingly.
So, open ResetMedVar and click test to set the variables to 1. Tick the MediaBoot and MediaControl profiles to activate them and apply to exit Tasker. Insert your headset!
You’ll be prompted with the first pop-up asking if you want to active the media controls. Click to activate (it will disappear in ten seconds and cancel otherwise). Shortly after, a confirmation pop-up will confirm the files have been copied correctly. Shortly after that, another pop up will confirm you wish to proceed with the fast reboot. Click to activate and you’re device will reload the system. It should take around 15-20 seconds.
When the device boots back up, the Button Saviour application will be loaded, to ensure you have button control if things go wrong. Pressing the little arrow on the right hand side of the screen will enable a back button that you can press to back out of the screen. You media player should then load. Choose a happy tune (from a folder/album/artist that has more than one song) (not forgetting you can’t use the back button other than on the screen!) and turn the screen off.
Hopefully, search will skip forward a track, back will skip back a track and menu will play/pause the playback. WHOOP!
When you’ve finished testing, switch the screen back on, unlock it if necessary and then remove the headset. Tasker will then perform the above steps again, replace the files back to the original ones before confirming the fast reboot.
15-20 seconds later, hopefully all of your hardware buttons will then perform as normal!
Job done.
Extras
I couldn’t get the trackpad/optical joystick to perform an action on my device. There is an entry at the very end of MediaContOn and MediaContOff after the STOP. These entries copy and reversely delete a curcial-oj.kl file to /system/usr/keylayout/ that is supposed to enable the trackpad to work. Drag these to position 5 if you’d like to test them on your device to see if they work. Let me know!

Heh, looks like Brandall is taking Tasker to new heights.
Nice work mate, but I just have to add something though...
Using this can help, BUT, it can also "cripple" those Tasker scripts you've posted about battery saving.
Using Tasker for zipping files and extracting them loads my CPU to the max, also, anything that uses notifications and file reads/writes does that too, eventually, using more battery...
Using this I can see a situation where some user might just lock/unlock their screen very often and rapidly, this might cause a major stress on the CPU, ultimately, nulling and voiding your battery saving scripts and potentially causing harm to CPU/battery/device.
And in any case, turning the screen on to switch tracks is really not that much of a hassle, for me anyway.
This is how I see it, just my 2cents.
But keep up the good work buddy, you seem to have been able to utilize Tasker to a MUCH greater extent than what I was able to, will definitely follow your posts.

Hi Gramlengo, I guess I can count you out as a Beta Tester!?
The logcat/zipping entries should be deleted from the other profiles if you aren't analysing them anymore to see what your phone is up to. As you said, you will use much less resource that way (they will be removed in next release)!
I do a lot of running, so being able to skip track through my pocket (without waking the phone) is essential = my motivation for working this out. For me, being in screen off state therefore won't clash with the other profiles... although saving battery power wasn't a consideration in this profile - there is plenty to spare these days The notifications are for testing and user interaction - I don't use them in my profile, it just overwrites the file and reboots...
I'm running out of ideas for the next profile, I'm open to suggestions! Good to hear you're following my posts, I'll look forward to your feedback - now sign up for this beta, you know you want to....!
Heh, I'd love to be beta testing your ideas!

Looks like you might be alone there!!
Alright, finally got a time to test this one:
First, I plugged in my headset and got the two pop-up questions which I clicked activate on. Then, nothing happened. After about 10-15 seconds I got a superuser request for the locale execution plugin which i clicked allow and remember my choice on. Still nothing happened. After another 10-15 seconds I got another superuser request from busybox and quickly after a superuser request from locale execution plugin, both which I clicked allow and remember my choice on.
Then the phone finally fast-rebooted. When it was back up and fully loaded, the music application started. I started a tune, switched off my phone screen, and clicked the back button, nothing happened. I clicked the search button, nothing happened. I turned the screen back on, and hey, the back button still functioned as a back button, and the search button still worked as a search button.
What did I do wrong?
My device is a desire HD running leedroid Hd (latest version and kernel).
Does this have something to do with the Desire HD having capacitive buttons?
Will try again, but this time by remapping the physical volume buttons and the physical power button.
I have also attatched the original keymapping file, and my modified one.
Edit: That didn't work. Opened root explorer to see if the values were right, and they were. I also noticed another keymapping file called "spade-keypad-v0.kl" (without the "). Will try to edit the values in this file to see if that will work.
Edit2: Editing the back,menu and search button in spade-keypad-v0.kl didn't work. Will try to remap the volume and power keys.
Edit3: Ok, two more combinations to test: Editing the capacitive buttons in both files, and afterwards editing the physical keys.
Edit4: No luck, I have attatched the other spade-keypad-v0.kl for you to look at. Hope you can fix this!

Appreciate your testing torsrex. Nothing's ever simple is it... Did you fast reboot every time you applied changes to the files?
In the file spade-keypad-v0.kl, did you set them like this:
Code:
key 102 HOME WAKE_DROPPED
key 139 MEDIA_PLAY_PAUSE WAKE
key 158 MEDIA_PREVIOUS WAKE
key 217 MEDIA_NEXT WAKE
Check they had applied with a file explorer first and then fast rebooted?
Let me know!
I checked that the files were changed every time with root explorer. I also tried a normal reboot if the fast reboot didn't work (Did this all the times I had changed a file), and I tried copying the files manually with root explorer.
I tried to change the values of the spade-keypad-v0.kl to what you typed, but that didn't work either. Maybe I should also mention that after I changed the back-key, menu-key and the search-key to media controlls, the home button also won't work.
Does this have something to do with having capacitive buttons and not physical buttons (I think the button turns them self off when I put on the screen lock)?

Ok, sounds like you've been pretty thorough. I knew the set-up would be different device to device, but didn't think it would be difficult to establish how.
I guess all we can do is use an app to discover the changes that need to be applied on your device. Check out ButtonRemapper and after it applies the updates, take copies of the files it has adjusted (assuming the app works for you!). Let me know!
Tried the buttonRemapper application from the market, and It worked! The buttons (menu, back and search) got remapped, but I noticed that the screen needed to be turned on before I could press them (no need to enter any pin code or dragging down the slider, just pressing the unlock button). I have atattched all of the kl-files.

Ok, I'm confused now... I can't see any difference between what you did to what the app has done...? Can you?
When the changes are applied in the app, it must take a copy of the original files it's about to change and store them somewhere. Is there a ButtonMapper folder on the SD card? Perhaps have a look in there when the controls are changed for media? See if there is just one file, or if there's an additional one we haven't considered..?
Then we'll solve the screen off use!
Hm, can't find the backup folder, it isn't on the sd card and it's not in the keylayout folder.

Damn it! I'm going to have a search around and see what I can come up with... I'll be back...
Is your device fine after the fast reboots? That's why I put this as a beta as I didn't know how stable it would be compared to a full reboot...
Using the buttonremapper application, I didn't face any issues. Using the tasker-profiles (editing the files manually) caused the home button, back button, menu button and search button to not function any more and I had to restore a nandroid backup. Maybe you should get the correct setup files for each phone before you take it out of beta
By the way, I sent a message to the developer asking him where the buttonremapper application saves it's backup-files, hopefully I will get a quick answer!

Good work! And thanks for testing... I need a lot more volunteers like you for each different device, but I don't see them flocking!
Just got a reply from the developer: "in its data directory in the subdirectory files: /data/data/com.beansoft.buttonremapper/files."
So here you go.

Good work again Sir! I'll take a look at the files and see what else is needed for devices with capacitive buttons (which I'm hoping is the only difference...).
Someone just released a trackpad wake for all AOSP ROMs (without messing with the kernel?) over in the Desire forum, so I'm currently looking at that too...
Always something to do... speaking of which, I need you over here next
So I was bored tonight and thought I'd try and revive this project.
What I've got is still a work in progress, but it basically involves using Buttonremapper to reassign volume_up and volume_down to fast_forward and rewind, then use Tasker's 'state: media button pressed' to forbid any other apps from responding to those two buttons and have them act out Tasker tasks only.
One button is set to play/pause media (if screen is off) and raise volume (if screen is on) and the other set to skip forward media (if screen is off) and lower volume (if screen is on). The end result is almost full media control from hardware buttons without having to look at the phone or take it out of your pocket: use the volume up and down buttons to skip and pause tracks, or press power to turn the screen on and change their function to volume up or down temporarily before reverting back to skip and pause as the screen times out. You don't need to be looking at the screen while this is happening.
The problems at the moment are:
1) While two buttons have effectively been made into four, there are five necessary functions - volume up, volume down, play/pause, next track, previous track. I figured previous track was the least important but it would be nice to have it as well.
2) Normally the volume buttons in Android are context-sensitive, changing media or system or whatever volume depending on where you are. With this they're always assigned to media volume, so you'd need an app like Audiomanager or something to change the volume of other things.
3) Other problems that I haven't realised yet.
One other thing, Tasker's 'state: media button pressed' lets you set both long presses and short presses, but they don't seem to play nice together. I think both the long press and short press tasks activate and conflict when the button is held down, but I haven't had a look at this yet.
I don't like how the screen turns on when I change the volume for music in my pocket, so here's a workaround I found:
- Use Root explorer (or similar) and browse to /system/usr/keylayout/
- Mount system as R/W
- Long press ffa-keypad.kl and open with text editor.
- Remove the words "WAKE_DROPPED" next to key
115 VOLUME_UP
114 VOLUME_DOWN
Only remove the "WAKE_DROPPED" words and save the file. Restart your phone and wake on volume button press should be disabled.
Thank you for this! Actually was just running into issues with this yesterday. When I run, I use my phone for music, and every once in awhile, it'll randomly decide to wake, and since it's in my pocket, it'll just start going crazy pressing buttons, pocket texting random people, and skipping tracks, haha.
Help please

Could you post the entire file because I made a mistake and disable ALL and now I can t remenber wich ones than you !
Thank you for this! Was getting really annoying before. This is perfect now. Super clear directions. Thanks again.
Old thread, but same questions I suppose. I would like to disable wake on volume up for my Droid4 running ICS 4.0.4 but I don't have ffa-keypad.kl in my folders. I found several files that contain 114 and WAKE, but I'm not sure which one needs editing. I found the key layout info:
http://source.android.com/tech/input/key-layout-files.html
That indicates that changing the wrong one will just be ignored. Any guidance on determining which the right file is? Like I said, there's ~20 files and at least 4 have 114 in them. ES File Explorer doesn't seem to let me search file contents that I can see.

Change it in all 4, or plug ur phone into a computer, adb pull the entire folder and then search contents from there.
Then edit the files using notepad++ or notepad2 and then adb push them back
I actually solved this through searching a bunch more. The basic answer is that you need to edit whatever file ends with "-keypad.kl". For my Droid4 , that's "omap4-keypad.kl". Thanks for the response though!

Hi,
I have seen this tweak/app to wake phone by using volume button mentioned a few times but no instructions on how set it. Any information that can be shared on how to do this?
Thanks,
Chris
that would be a nice option to have. sometimes the phone feels "too tall" to reach the power button and pressing the side button while it lays on a table is much easier too.
Also looking for this mod - the Sense ROM forum mentions that it is something to do with android.policy.jar?
Leedroid ROM has this.
I know this is a late reply but I found that the tap tap app works well.
I combined it with no lock, so i can just wave my hand and it'll go right to home screen, bypassing the need to use power button, moving the htc ring and pattern lock.

I would highly recommend avoiding this app. I installed, played with for a few minutes then put in my pocket for the drive home from work. When I got home, my phone was locked up, too hot to hold and upon reboot, I had no data connection. Literally nothing I tried returned my data until I did a full wipe and nandroid restore losing a week of data. The app didn't even work reliably in the first place...maybe 1/3 times would it unlock as promised.

Ok, I'll experiment it later with my jeans. Do you remember the settings for your sensor? (sensitivity, how long will sensor be on). Can you suggest an alternative to wake up the phone w/o using power button?
Some say no lock can wake phones via volume key but that doesn't work on my one s.
Brief instructions
It's quite easy actually. Here is a very brief overview.
1. Unlock the bootloader
2. Install a recovery
3. Install something like SuperSu
4. In /system/usr/keylayout/keypad_8960.kl, replace the "key 114 .... " line with "key 114 POWER WAKE". Voila! Now it works, but not when it goes to deep sleep to fix that
5. do this http://forum.xda-developers.com/showthread.php?t=2038726.
If you need a more detailed answer or encounter some difficulties, don't hesitate to ask.

How could i fix that ?

Hey, sorry for the late reply. Indeed, a button won't fulfil 2 purposes at the same time. What I do when I want to lower the volume is press the volume_up button. At this point a scroll bar appears on the screen. I then lower the volume by sliding the bar
Hello all,
Recently the power button on my Nexus 5 has been acting really weird. Sometimes it works flawlessly, others it requires pressing it really hard to work. In order to prevent it to stop working indefinetely, I am looking for a way to remap my volume-up button so it can work as a power button. I don't need it to turn my phone on or to work in the recovery mode (from what I read, it seems to be impossible), only when Android is running.
I've already tried some workarounds:
1) Volume Unlock Power Button Fix app: I tried it, but it just allowed me to turn on my phone with volume but not turning off. Also, it drains a LOT of power.
2) Buttonremapper app: It would theoretically do exactly what I wanted, but did not work at all.
3) Editing generic.kl: I tried switching volume-up and power buttons codes in generic.kl, but also did not work. Maybe I need to modify another file?
3) Xposed Framework + Additions: The installation of Xposed went Ok, but after installing Additions module I got stucked in bootloop. I am running Android 5.1 stock, maybe this module is not yet compatible.
So, can anyone help me? Do I need to install a custom ROM?
PS: I live outside US, so no warranty for me. Otherwise I would just use it
Thanks in advance for any help!
Cheers,
Humberto
Hi folks,
Just a heads up for anyone who might be facing the same issue. I decided to change from stock to Cataclysm ROM due to some specific features (listed below). After the installation, here's what I did to work around this problem:
1) Enabled "Volume wake" and "Sleep button on status bar" in "Cataclysm Settings / Miscellaneous".
2) Enabled "Swipe to sleep" and resized NavBar to 115% in "Cataclysm Settings / Navigation bar options". -> This way I can swipe in NavBar at any time (except lockscreen) to turn off screen. I raised it a little to facilitate the swipe gesture.
3) Changed Lockscreen Dialer shortcut to ""Turn off Screen" app shortcut (just search for it in the play store) in "Cataclysm Settings / Lockscreen options" -> This allows me to just swipe right and turn off the screen when my security settings are disabled (which accounts for most of the time). I found it way faster than pressing sleep button in status bar, especially when I'm driving and I can't look at the screen. Plus, I don't really use the dialer function of my phone so often since the invention of Whatsapp ;P
I realize this is not the perfect solution, but I don't see a better way to deal with this power button malfunction problem (except from a hardware fix).
Hope this helps!
Cheers,
Humberto
PS: I am really enjoying Cataclysm. It's a very nice ROM, completely stable and with a lot of other interesting features aside from the ones mentioned above. I strongly encourage anyone to give it a try!
I'm facing the exact same problem but I really need to eliminate the power button or I will need a power button fix soon.
The solutions you found hthiengo are good if not needing to turn off (or worst: running out of battery, something that happens me sometimes). I'm in the situation that next time I hit power button I will need to replace the button, or throw the nexus away
I did installed the xposed additions for lollipop but it is not working, and the Cataclysm trick is not enough in this case
Ok, after some research I've found a temporary solution:
For the power button you can remap modifying the file gpio-keys.kl under system/usr/keylaout (i wonder why anyone could figure out thise before, no that difficult). I would like to map power button leeaving it useless but I've found it impossible to remap the power button (probably because the key number is not 116). I would have liked to see xposed additions to help me map the keys but is not functional at least for me.
If the phone runs out of battery I've found that if I plug the power cable by pressing both volume buttons at the same time, eventually it starts up with the bootloader so I can plug the pc cable and it will reboot sucessfully.
So despite the phone know is pretty disfunctional (not the best phone for a hurry without battery), I can still use it for some weeks before I plan buying a new one or something (or I find a place for reparing). Its a shame I could not find a better solution for example, ADT when powered off so I could just reboot it by using ADT reboot command while powered off.
And It would be really amazing if the volume up button could also power it on from the powered off state.
In my case the power button is broken, but sometimes it gets stuck and puts the phone in a reboot loop: To avoid pressing the power button accidentally I've made a hole in the protective case so its pretty difficult to access it.
That's all for now. If anyone can make it better I will be glad to hear him/her
