Great work. I can't wait to see future developments of this once the bugs are ironed out.
[APP][4.1+] Knockr - Lockscreen

- Start date
Can someone elaborate on the "keep screen off" option?
I'm dumb. I read it ten times, and do not have a clue.
You are not alone man, I'm lost too

Knockr keeps your screen on, it turns out fully black so you don't notice it, but it's always turned on so that Knockr can always work.
This feature prevents that from happening, so your screen is turned off and this means you have to manually turn on your screen in order for Knockr to work
No need to be verbally abusive. He was asking a question because he didn't know the answer. That's the reason most people come here, to learn and understand more. This type of communication is not welcome here and will be reported if it continues.

I can attest to the fact that knockr does not drain the battery. Charged my device 100 percent, turned wifi off and slept at around 12am. I woke up by 7am and I still have 96% left. The key here is make sure to cover the proximity sensor to keep Knockr from constantly running and slightly lighting up the screen. I have a leather pouch case that does it well so for those that don't have it, make sure it's face down when not in use. If you ask me it kinda works like other proximity sensor based app so I'm contemplating which one to use.
Samsung Galaxy S series and Note series users, does your display still slightly lit up when in a totally dark room with knockr running and proximity sensor is not covered?

Yes, I can confirm that on S4 mini. And since last update the hardware buttons LEDs are always on too. Before they lighted up for a few seconds, but now they're always on.

Thanks for the reply, my buttons don't light up all the time, around 1 second, but maybe because I'm running on a MIUI Rom.

In devices like the M7, you can have a kernel that uses S2W or DT2W, that can be used to turn the screen on as opposed to using a Power button. I have "Keep screen off" checked, so that allows me to use my kernel's DT2W feature, then I swipe the direction I want to get the final output. At this point, this app rocks! :good::good:
I thought I had gotten complaints about the capactive buttons staying on so I tried to fix it but it seems it was the on screen navigation buttons that people were complaining about and I'll take that fix/mess up out in the next update. It should be out sometime this weekend.
With that fix on my S5 it had no effect though.

Please, read the thread, you will find there are lots of posts about battery consumption on OLED and non OLED screens.

I know I said the next update would be up this weekend. I'm sorry but I ended up falling asleep in the afternoon both days and just ran out of time. I have added a lot of new things in this update as well. I'm going to try and upload tomorrow night when I get home from work.

Battery consumption for this application is not significant. The sensors will temporarily shut down for more than 10 seconds and back normally works (air-wakeup. ...) In addition to the errors mentioned above, I think the app works well on screen or supper Amoled . ( tested on S4 and Note3 and works fine ) thank you.
On my s5 the phone was awake the whole time since disabling it, it came back to normal

I notice at night, Knockr will slightly illuminate, turning on the Nav bar continuously and even waking the display to the homescreen. Something I noticed is that my proximity sensor must really be sensitive and is causing these effects. I realize the light sensor would be more valid for the effects, but this occurs with the phone on a table/couch, and only at night.
Maybe you could add 'Orientation' as an alternative to the proximity sensor. This could... a) allow Knockr to be off when phone is upside down, etc., and b) no need to have the proximity sensor running.
Another good option is to make a Tasker plugin for Knockr that would allow customizing Knockr on/off, based upon conditions.
BTW, this is great work for a guy who doesn't even have a rooted device!

Ok just uploaded the new update. Should be available in the morning (EST).
Some of the highlights being 10 new gestures and I changed the 'keep screen off' option to 'lockscreen only' and created a sorta lockscreen out of it (if this part becomes popular I will try and add the ability to have widgets). The lockscreen option makes Knockr a much better app in my opinion and opens it up to other devices outside of OLED ones.

99After 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.
**EDIT**
The newest update 2.1 now includes Knocks. Knocks is like LG's Knock Code. You can create multiple Knocks to unlock or open apps.

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).7Looks like another abandoned thread by developer. Wonderful app though
Not abandoned. I just have no new information to give. I am trying to update knockr with some more features but ever since android l preview came out eclipse has been working correctly. Sometimes it works and other times it tells me that all my projects have errors. Just have to be patient.
