[REF]Managed HTC Light Sensor SDK released (with source)

I published the HTC Accelerometer SDK a while ago, and have been spending some time off and on trying to find out how to get access to the Nav API. No luck there yet, but I did figure out how to access the light sensor.
The updated API and source is available at:
http://www.koushikdutta.com/2008/07/htc-light-sensor-sdk.html
Koush

can you give us compiled exe?

where are the lightsensor? is it the front/back cam?
how often will auto light adjust update?
alltime? once per power on switch? once per minute?
when the autolight is not set, and it will be done by frontcam, we can safe cams energy, by switching off automatic backlighht adjust. cameras are needing a lot of power.
can anybody confirm that?

WooooWWW this keeps getting better!
Thanks HTC

Please.. Somebody will make a "really" adjustable light settings util with this SDK.. I want to set min backlit level to lower for totaly dark enviroments... because default one is too much than required..
Sorry for my poor English..

Sure, I'll make a utility to do that. Give me a bit though, I'm coding up the Nav sensor SDK right now.

feature request
disable light sensor when call is in progress.
enable light sensor back after call was terminated.

sensor option
Thank you,
I have noticed on the new Bang & Ollefson and another new highend phone [not iphone] they are set so that when the display is away from the air is is visable...against ear off......thus...
when you are looking at the display it is visable
when phone is covered by ear...display is off
take phone away from ear....display comes back on
back to ear display goes off....etc...
This is a fantastic feature and has a wow factor as a sales tool.

This is exactly happen what i saw a few days ago..
iGo2008 running, a phone call received and i'm noticed display on & off with light sensor working !!!! I'm looked at the display it is visible (...from 10-15cm distance from my ear..) , when phone is covered my ear...display is off... I'm tried over and over again... still worked at the end of conversation... But when i'm closed iGO2008 and tried again... Not happen again...
Any ideas ???

Nice work Koush - and I completely agree with the above quote. I'm surprised HTC didn't have this already included, having to press a button to wake the display is kind of stupid since it gets turned off by the light sensor

Light sensor is just left of the front face phone speaker (inside the speaker recess).

This happens with the iPhone too.
It's exactly what we need to make the Diamond much better. I don't want the backlight on during a call as its a waste of battery - but I hate having to push the power button during a call if I need to enter a number or change to speakerphone etc.
How could HTC have missed out such a simple feature? Hopefully this is something that can easily be coded in? Fingers crossed

Any news here? I'd appreciate a tool or tweak to define minimal backlight level for myself because of the same reason.

somebody got ahead regarding the customization of automatic backlight changing with this api?
regards

this would be great if someone with programming skills looked into it!!! ie not me!

You don't have to press power button while on call to enable the backlight. Pressing the middle button (circle) will enable backlight and wont do anything with the call

Proximity sensor in Touch HD

I recently read on gsmarena that the touch hd has a proximity sensor for auto turn off.
is this true?
if yes, could we use this sensor to automatically answer a call for example
maybe we can add to the sensory sdk of koushi a class for the proximity sensor.
just a thought

I'm guessing that the "proximity" sensor that has been discussed is actually the light sensor beside the earpiece. This can be used to turn the backlight off when applied to your ear during a call. using this as a means to asnwer a call would not be reliable, and what would happen if the phone is in your pocket etc etc.

i think is just like the iphone when u place it next to ear the it goes off to save battery ?

It doesn't work like the iPhone.
The HD, like all the devices using a Qualcomm chip, is just switching off the screen when a call starts, the phone next to the ear or not. It just doesn't use the light sensor at all during a call.
I asked for a soft that permit the use of the light and G sensor during a call to switch off/on the screen. You'll find more info here : http://forum.xda-developers.com/showthread.php?t=451456

Proximty and resume
The proximty sensor will turn off the screen when places the phone next to your ear. I guess this help to prevent accidental touch on buttons. However, I have a problem with my new Touch Pro2:
When the phone is placed away from your ear, the screen will go back to home instead of previous phone dial pad. When I listen to my voice mail or join a conference, a lot of navigation is needed in order to dial the command buttons.(press a 7 for next, or # for ....)
Any chance to make the screen resume at previous location? My first improvement suggestion to HTC.

Concerning this sensor, funny I thought it was some myth as mine never seemed to work or only half assed. Then after flashing many diff roms and settling on the "energy" Rom I see that much to my pleasent surprise it works perfect, just as intended. This is a fantastic feature and my first device it has actually functioned properly on.

hi
yeh there is a setting somewhere that lets you go straight to home when you turn the device on instead of loading the screen it was already on.
its set to default but you can change it.
i forgot what the app was called though, i think it was possibly an option in hd tweak or something

THERE IS NO proximity sensor in touch hd

However I've been told that "Touch Incall Screen Tweak" does beautifully on the HD and probably it's what you´re asking.

From what I've been reading spec wise I believe your correct, but I cannot explain then why when I make a call with the HD up to my ear the screen goes dark then when I pull it away to input a number from the kp it lights up. Is it the light sensor then? I'll check in the NRG energy ROM forum and search for some info as I'm running his ROM. I love this feature btw and have not noticed it in any other ROM I've tried.

Turn off screen when phone is face down?

Is there an app that will turn off the phone's screen when it is faced down?
I've been looking everywhere to find such and app and have not found one.

You shouldn't need a tweak to accomplish that. When you put the device face down, the proximity sensor will be blocked and will turn off your screen automatically.
(Unless you put it face down on an overhead projector surface!)

I'm no programmer but this seems like it would be relatively simple, I'm surprised it doesn't already exist (or if it does, a quick search for me turns up nothing).
it would have to use the light sensor as well as the accelerometer, though. If you ever look at your phone while laying down, the phone turning off while upside down would not be very useful

That feature only works when you are on a phone call.
It doesn't work outside of the call function unless I'm missing something. My screen definitely stays on when I put it faced down.
The reason I'm asking for an app like is is because I've been listening to audiobooks as I go to sleep. Since the speaker is on the back I leave the phone faced down on my bed. I'd like the screen to automatically turn off when I do that to conserve battery life. (I know I could just hit the power button, but I'd rather have something do it automatically).

Thanks for pointing out Gyrator for this. I never thought about using it for this.
Works like a charm for what I asked.
Now if I can find something that will turn the screen back on when I flip it face up again I'd be set.

Tonight I have written a little APP that will switch off the backlight when face down and turn it back on when you flip it over.
Seems OK on my device.

[Q] Alternative ways to turn screen on/off

Hi all,
I'm wondering if there's any alternative ways to put the Nexus 7 (or any Android device I guess) to sleep/wake it up. I'm thinking something along the lines of an app that forces the touch screen to stay active but turns the display off so you can use touch input to activate wake/sleep.
Might be a bit of a stupid question. The reason I ask is because my N7 is mounted in my car and the power button isn't easily accessible.
Cheers for any tips..

Not sure if this helps but I have a case that I bought for my N7 and when I open it and close it the screen turns on and off.

Thanks for that but nah, it's mounted in my car dash so a case won't fit..
But that give me an idea.. does sliding a magnet across a specific point on the screen turn it on/off? That's the idea with the smart cases right?

Yes,
The magnet is somewhere to the bottom left of the device (i would say to about a quarter from bottom up and on the black contour) . If you can add an sliding magnet (make sure is weak) then you can lock/unlock screen.

Nfc tags dude i wonder if they would work

I know some kernels can enable touch wake. I imagine it can incorporated soon. On my Galaxy Nexus, there's an app I downloaded that allowed a specific screen swipe to wake the screen.

Hey man. I used to have an awesome app on my very first Android tab years ago. It would turn the screen completely black (via home screen or notification icon) without actually putting it to sleep. Because it wasn't really asleep, a double tab would turn the screen back on. I CANNOT FIND IT FOR THE LIFE OF ME! Anyway, after reading your question, I searched for an hour, because I could use something like this for my setup in my car.
So, I found something that turns the screen both on and off, and actually works on my N7. Search for Proximity Screen Off. I installed the free lite version, and it works. I found out the screen won't turn on though, unless you disable your lock screen. Play with the settings to your liking.
Oh, and since we don't have prox sensors, you can use your ambient light sensor. Good luck, lmk if it works for ya.

It's called PGM Nexus. I almost don't want to give up my Galaxy Nexus (but I sadly still plan to) just because of this one app alone...it is so godawful nice to be able to swipe, or simply double tap the screen to fire up the screen. Unfortunately this app apparently requires some deep voodoo to work as its kernel related, and applies strictly to the Galaxy Nexus. I know a bunch of people have already started bugging the developer to make a version for the Nexus 7, I'd suggest piling on. :fingers-crossed:
It's apps like these that make you realize how superior the Nexus devices are at getting really good customized software over other devices.
I do wish there were some other options for the Nexus 7, like using the front camera as a proximity sensor of sorts to detect a handwave, or simply shaking the tablet.

Hello. I'm not sure if it helps you, but for turning off screen I use Nova Launcer (alternatively you could use Apex Launcher - as far as I remember, it has gestures in its free version) with Screen Off app by Katecca. I've set Nova Launcher to react to swiping up screen by executing Screen Off app. So I have to turn on screen by pressing button, but to turn off I just swipe up screen.
Best regards,
Artur
