Default [APP][4.1+][OLED] Knockr - Motion Gestures Launcher

After seeing a lot of comparison videos of the HTC One m8 and the Galaxy S5 I realized one of the big things HTC has is their motion launch gestures. Unfortunately for HTC it is limited to doing just a few things. So since the Galaxy S5 has an OLED screen which is turned "off" when displaying black pixels, I figured I could create something like the motion launch gestures that uses minimal battery.

So I created Knockr an app that allows users with OLED Screen devices, like the Samsung Galaxy S5 and Moto X, to quickly enter an app with gestures without having to turn the screen on.



Gestures include:
Double Tap: Double tap the screen to open any app you choose or unlock the screen

Swipe Up, Down, Left, Right: Users can set each Swipe to open a separate app or unlock the screen

Long Press: Long press the screen to open any app you choose or unlock the screen

Volume Up when in Landscape: Pressing the volume up button when the device is in Landscape will automatically open the camera

I am still working on improving some of the things in Knockr, but wanted to post it on here to get some feedback and suggestions to make it better.

Change log:
Version 1.3:
-Added 10 new gestures
-Changed 'keep screen off' to 'lockscreen only', so Knockr can be used as an alternate lock screen.

Going to give it a try with my Galaxy S4 Mini, I hope it's not too harsh on the battery. Nevertheless this application seems like a great idea, Thank you.

EDIT: Seems to work very well. Just a few things I noticed.
-The screen can turn on by a single touch to the screen (it will then display lockscreen)
-The backlight keys turn on after the app is activated once the screen is locked (the keys are only on for a few seconds on my phone anyway, no big deal)
-Is it possible to decrease the delay between when the phone is locked and when the Knockr app is loaded/active?

You said that this is for screens with OLED yet someone commented checking whether it would work with their S4 Mini. Now I thought that S4's had AMOLED which was different, if I'm mistaken, does this mean that it will work on my S4-19505?
Thanks, it looks brill by the way.

AM-(OLED) your device has an OLED display. It only works with OLED type screens cause they use no power to produce black screens.

Only one touch and the screen is awake to show the lock pattern on Samsung S4.

What an awesome app! My only recommendation is to take away the one tap to turn on the screen, as the screen can accidentally turn on in your pocket very easily and cause unwanted battery drain.

Thanks for the feedback. It shouldn't use much battery especially if you use the power management since you probably wont have your phone turned off to often outside of your pocket during the day and if you do you can just turn it over and still get the same benefit.

I have already uploaded a new version that has removed the single tap action so there aren't any false touches registered. It also made the screen on an option to choose for any of the gestures. It also fixes a bug that cause Knockr to close when the orientation was changed after being pocketed.

Unfortunately I don't think there is a way to load Knockr any faster since I already have it setup to load as fast as possible. The problem is that I have to use a broadcast receiver to receive the screen off and the broadcast takes a little bit of time to be sent out (I'll keep looking for ways to make it faster though).

Really cool app!

Few recommendations:

1. Any way to show clock and notifications every couple of seconds? (Ex 15s)

2. Way to bypass knockr when power button is pressed.

Thanks!

Default awesome app

awesome app.
but there is delay while unlocking phone (or performing any action while screen is locked).
i don't know it is because of my s3 or app
but cool idea.
one more suggestion screen should be unlocked after pressing power button.

mind blowing app.
works great.

thanks for this and keep going on.
it is really nice idea.

questions :
can it detect multi finger on screen off? we might get more gesture thts why only.
screen segmentation? means on some part of screen it detects then that gesture recognized.

just some ideas.
Devices :
Note 2(N7100 white 16GB) : DN3 4.4.2 Kitkat , Stock Kernel
S Advance(GT-I9070 16GB) : Pure Vanilla v3 , Cocore Kernel
Moto G(Dual Sim 33) : Stock Non Rooted , Stock Kernel
