Hi there,

here is the mod for skipping music tracks when long-pressing the volume buttons. This is for stock ROM 14.71.8 DEODEXED ONLY!!
So, if you have an unlocked bootloader and have root access, you may apply my following mod. I'll guide you step through step as we got no CWM recovery yet, so you must do it manually.

- download android.policy.jar and move it to your internal SD card with an explorer or via adb:
Code: 
adb push android.policy.jar /sdcard/

- after that type in the following commands, beware that su wants you to grant root access (SuperSU popup)
Code: 
adb shell
su
stop
mount -o rw,remount /system/ /system/
cp /sdcard/android.policy.jar /system/framework/
mount -o ro,remount /system/ /system/
reboot

Done! Enjoy this mod :)

Reminder: Although this mod was tested on my device, I'll take no responsibility if you damage your system, so just do it if you know what you do!

If we have CWM, I will provide a flashable .zip then.

Modification?

Thanks for this, something I miss from my old Sony Ericsson are the physical music player buttons.

I was wondering if you could point me in the right direction of modifying this to make a small alteration; instead of vol-down skipping backward a track I'd like it to have the Play/Pause functionality. That is a button press that I'd use much more often!

Another (perhaps more complicated) solution is to have a double-tap of the power button do this Play/Pause, with double taps of the volume buttons providing the skip tracks effect.

Change the keycode in line 48 in com\android\internal\policy\impl\PhoneWindowManager$VolumeLongPressR.smali from 58 to 55 and you are done.

Unfortunately this mod doesn't support double taps and I don't know how to integrate this easily :)

Sure.

You have to add 2 files in com\android\internal\policy\impl and have to edit PhoneWindowManager.smali.

Note, there are two/three different mods around here at XDA. I used all of them and I found out that the one with "lyapota" (you will see in the sources) works most reliable, whereas the other one (I used it in the Nexus 5 mod) works too but is a little bit less responsive and doesn't work with all media players.

The hardest part is to find the right variables, if you want to use this mod in other phones. The first time I did this, I used this thread as a good start but you can't simply copy as this won't work then :)

Attached are my modded .smali, the 2 ones you have to add and a .txt with the diff's to the original MotoG-smali.
