[APP][XPOSED][1.0] hellsCode - A KnockCode mod for hellsCore kernel - Nexus 4 Original Android Development

Code:

Introduction, How it works, etc.
This is a KnockCode feature addition for hellsCore kernel on our beloved Nexus 4.
I created this mod by modifying Stratoks's dt2wake in hellsCore kernel that you can input a pattern on the screen, which is separated in a grid of 4 rectangles (For further explanation search for LG KNOCKcode on Google). I record that pattern in Touchscreen driver, and then write it into a sysfs file.
In the second step, the hellsCode config Xposed module reads the code from that file, and compares it to the code saved in its preferences. If the code was correct, it finishes the Keyguard to unlock your device.
If the code is wrong, the screen still goes on, but this time shows the Keyguard. That means you can also use it as QuadrupleTap2Wake
At the moment, this mod heavily relies on Xposed, but I hope that I can integrate this mod directly into some custom roms, I will write a guide for rom creators later.
Since B80, my mod is merged into the official hellsCore kernel.

Installation instructions
* You need Xposed for this to work properly
* Install hellsCore kernel from here (since B80)
* Install hellsCodeConfig.apk, activate in Xposed installer, reboot.
* Set up your code in hellsCode Config app.
* You need to have doubletap2wake enabled in your favorite Kernel manager, and also enable the mod with
echo 1 > "/sys/devices/virtual/input/lge_touch/hells_code_enabled"
To disable temporarily, do echo 0 > "/sys/devices/virtual/input/lge_touch/hells_code_enabled", to remove permanently uninstall the hellsCode Config app.

FAQ
Why isn't there a version for CM?
-- There actually is one, just take a look at the official hellsCore kernel, which includes the mod since B80.
The device sometimes unlocks when woken up with the power button, why does this happen?
-- That was a bug, fixed with config 1.1

Whatever. With "" it has nicer formatting, and is most times better when you have spaces in folder names.

Feedback
Really thanks! I really like knock code. This mod works great, but with three problems :
1. Lock screen is shown for a milisec, then unlocks. Not really a big problem.
2. After unlocking, status bar is sometimes pulled down.
3. Power button is useless now. Every time I use power button, it bypasses lockscreen. Every time.
I hope this mod advances with updates! Thanks!

1. I still have to research which hooks suit better.
2. Really? That's strange, and has nothing to do with the mod..
3. That's a bug, read OP
Btw, if you touch screen once, and then press power button, it doesn't unlock. Will fix later today IF I have the time.
I unfortunately ignored school a bit the last few days, and have to catch up :/

For me is working quite fine, only problem i face is that the mod is not respecting unlocking sequence configured on hellscode config, if you tap on anywere 4 times phone unlocks.

Thanks for the quick reply. I will love this if the power button bug is fixed!
About the statusbar, I think it is related with my rom's feature(quick pulldown). Do you use stock rom?

Sure it unlocks? Or does only screen toggle on?

Nice work. I was waiting for this for a long time. I'll try the mod as soon as power button bug will be fixed.
Is there any chance you fix the micro lag that makes lockscreen shows for a millisecond?
Thanks

Exactly as much as original dt2w. Means not that much, maybe 1-2% overnight extra.

Not by now, sorry. But as @hellsgod will merge it into his sources, I'm sure he will also provide a CM build then..
