[FIX] Prevent home button from waking device, add support for HTC headset button

---

Hi all!

By altering the key layout files I have managed to
a) prevent the device form waking up by pressing the home button. I was very annoyed by the fact that I almost always turned on the device when pulling it out of my pocket.

b) Enable support for HTC headset buttons

Because I have moved form HTC to the SGSII I had a leftover HTC headset with one button and a 3,5mm extension jack (see attached picture).

Over the stock SGSII headset the option to use custom earpieces is a great benefit in my opinion. The sound and microphone part of the HTC headset worked out of the box, but the SGSII did not react to button press from the headset.

Prevent wake on home button, alter system/usr/keylayout/sec_key.kl
(Remove wake from key 102)

key 115   VOLUME_UP            WAKE
key 114   VOLUME_DOWN        WAKE
key 102   HOME
key 107   ENDCALL           
key 105   DPAD_LEFT         
key 106   DPAD_RIGHT        
key 103   DPAD_UP           
key 108   DPAD_DOWN         
key 232   DPAD_CENTER       
key 116   POWER             WAKE
key 212   CAMERA            WAKE

Support for HTC headset, alter system/usr/keylayout/sec_jack.kl
(Add key 76)

key 163   MEDIA_NEXT        WAKE
key 165   MEDIA_PREVIOUS    WAKE
key 226   HEADSETHOOK       WAKE
key 76    HEADSETHOOK       WAKE

What prog do i use to edit the KL file?

why would even want to do that?
I spent ages trying to get ROMs on my HTC desire to enable OJ wake and the HTC head is only good enough for the bin (not even the recycle bin)

sorry only my 2p

Well, if you like the device to wake on home button or not is a personal choice.

I think you have misunderstood the HTC headset support. The whole point is to NOT use the earplugs from either HTC or Samsung (they both suck). But with the HTC one you are able to extend with any 3.5 regular headset and still play, pause, answer and hang up without taking the phone out of the pocket.

Thanks

Is "WAKE" the only thing that can be set for these buttons, or are there other commands as well?
EDIT: Nevermind, the answer is here

Ahhhh I did the above to try and make a 'samsung' headset I have to try and make the button function work, but it did not work.

Must be a problem with the actual headset as I realise the command you added is just to make the button work while the phone is asleep.

Thanks anyway
