Happy tagging!

Great app! Very unique, I love it! Keep up the good work my man

Hey,
great idea!
Taking screens and analyizing colors seems to work for me, but upon saving and sharing, app crashes .
(replace 'xx' with 'tt', since i can't post links yet)
Log for save-crash:
hxxp://pastebin.com/9FhrUMNc
Log share-crash:
hxxp://pastebin.com/XB3U6xVE
Suggestion(s):
- change camera overlay (the bright rectangle in camera view)'s size, so that it reflects the number of pixels being analyized. (e.g. 1px analyzed: only cross, 144px -> 12*12 rectangle, 2500px = 50*50rectangle (you get the point )
- make color values selectable (text), so you can copy/paste them somewhere else.
Besides that, great concept, icon is ok aswell .
Cheers!

Awesome! Thanks for the feedback and the logcat! I'll look into the issues you're getting. I assume you are using a different locale than en_CA or en_US (as it appears you are from Germany), and that's where the share issue is coming from. I was considering having the size change for the overlay, I think that'll be a definite feature now.
As for the save error, I'm confused. The logs don't appear to be showing me anything. Everything seems to be going fine and then suddenly my Activity is force finished. I'll need to do some more investigating in that department.
EDIT: The share logcat confuses me as well, even though I'm sure I know what the issue is. I think the developer of your ROM has set the log level to very low.

Yep locale setting seems to be the problem. After switching it from de_DE to en_US saving and sharing are working fine.
Seems like everything from verbose upwards is being logged, i could give you a filtered log if needed?
(Fyi it's the stock rom if thats any helpful)

That's alright. If changing the locale solved the issue, then the locale is the problem

Would you be so kind as to post some screenshots of the app in order to entice users?
Thanks!

I'll try to get some screenshots as soon as possible, unfortunately my phone's battery exploded. I have a new one on the way and it should be here in the coming days. If anyone else would like to post some screenshots they're welcome to!
(I've tried to take some through the emulator, but they don't work because a) I'm testing a camera-oriented app on the camera-less emulator, and b) the camera uses a surface which updates while the screenshot is being taken so they end up breaking.)

Great App ideia, will follow this one up close congrats man

this is a great app idea but fc's on my droid incredible. i would love to have this app too.

Problem parsing the package

Post added to the XDA front page. Hope this gets your great app some exposure.

Shoudn't you have some way to calibrate the colors with a graycard? A color is highly dependent on the light that is emitted on it. A red object in daylight will give a diferent color than the same red object in fluorescent TL light...

@dirtsky are you using the en_US or en_CA locale?
@marko! I would suggest trying to redownload, I haven't heard of this issue as of yet.
@willverduzco thanks! There have been 300 downloads since last night thanks to the article!
@michaelarnauts I'm aware, but the thing is, LifeDropper is designed to capture colours as they are seen. If you see a colour under light, LifeDropper is viewing it in the same light.
An update that fixes the saving/sharing FC (due to locale) is now in the first post.

Wow, wonderful application! Working great on stock Droid Incredible... Few force closures now and then but still very useful!

@Cellulah is there any way you could provide a logcat for the FCs you're getting?

This is really cool. I bet someday you could do live updating with histogram data in the camera view!
Sent from my Thunderbolt das BAMF remix

@rycheme glad you like the concept! Awesome idea! I'm looking into doing capturing without having to take a picture (like Barcode Scanner).
Remember, if you like the app, mash the share button!
The next update will include linking to the currently under-construction LifeDropper site for the share feature, so the link at the end will be a link to your colour.

i'm sure i'm not alone on this... I'd really appreciate it if my camera could focus on the middle portion before taking the picture....
i would also really love this if there was a way to calibrate this stuff... maybe print out
100% cyan box... 100% Magenta.....100% Yellow... and whatever other colour might be necessary...
by the way ... this is an amazing App!!!
If it comes to the market ...i'll definitely buy it...

String resources from this app are attached for translation only. Do not assume you can use them in your own app without talking to me. If you want to use the strings in a revenue generating app please pm or email me beforehand for permission.
----------
Translating strings and arrays in res.zip:
All who help with translations will be acknowledged in the app. The res/values directory contains the files strings_localizable.xml and arrays_localizable.xml with the English (US) words and phrases that would need to translated. As an example here is how the translation to Brazilian Portuguese worked:
Step 1) Copy the strings_localizable.xml and arrays_localizable.xml files from res/values to another location.
Step 2) Complete the translation of the words and phrases inside the xml tags.
Example 1:
<string name="app_name">Weather Station</string>
becomes
<string name="app_name">Estação Meteorológica</string>
Example 2:
<string-array name="pref_notifications_when_entries">
<item>Rising</item>
<item>Falling</item>
</string-array>
becomes
<string-array name="pref_notifications_when_entries">
<item>Subindo</item>
<item>Caindo</item>
</string-array>
Step 3) The translated files are placed into a new directory inside the res directory called values-pt (or values-pt-rBR). I can take care of this last step I just need to know what language it is and if it is limited to a regional dialect.

The pressure will work on any device that has a barometer (e.g. Nexus 4, Galaxy S3, etc). The temp and humidity will only work on a Galaxy S4 b/c it is the only device right now with a ambient thermometer and hygrometer.

As I explain in the Google Play listing, the auto start permission is to run a very short service to re-set the alarm so background readings can be taken. The service only runs for a split second and then kills itself. If you disable background readings the service won't run on restart.

I am very interested in knowing how accurate the temperate sensor is working on the S4. Can someone test this out with a dedicated temperature reader and tell me how accurate it is or how off it is in Fahrenheit? Thanks.

if u can add a temp warning notification , then it will be perfect...
like i am able to set it to warn if the temp goes over xx degree..

Oh thanks mate! I got these readings, first is in my home and second is from outside. That second is littlebit weird because internet shows that there is only +4 celsius.

How long were you outside for? Perhaps the phone needed to stay outside longer in order to read the temperature correctly (away from other heat sources like yourself or the sun)?? Or worst case scenario is that the S4 temp sensor is not that accurate (we would need to find some specs on the sensors that Samsung is using).

Adjust Temperature
Is there any way to calibrate the temp sensor.?
Currently most readying are way higher than actual readings

I spent half an hour trying to find out why the thank you button is not available for me but couldn't find out why.
Thank You.Vry nice app.

About 10minutes. Maybe i need to try later, but usually i'm outside only 5-10minutes when i walk to train station or to grocery shop.

This was debated by me when I was making the app and I decided not to include it (but may put it in a future release if it is greatly demanded). The logic is that the temperature sensors are supposed to be calibrated to high accuracy at the factory and should not lose accuracy over time. Thus the "actual reading" you are referring to IS the actual reading that the thermometer on the phone is reporting. If it is higher than another thermometer nearby, it is higher for a reason (probably because of your body temperature heating the sensor, or the sun, or some other reason). The question is why fudge that?

i guess your mobile must be in your pocket.. try expose it to the weather..

This will be in the next release.

I've noticed that the temperature on the S4 is always higher. The reason is probably that the S4 is a heat source in itself! Unless the temperature sensor is incredibly well insulated from the rest of the phone then it will always be affected. I might test this and take a reading but only after having left the phone off for some time like 30 minutes (to let it cool sufficiently) then switch it on and take the reading before too much heat has built up in the device.

[Q] Tilt sensor is off for some apps, possible fix?

Before my Asus tf700 Infinity, I owned a Samsung Galaxy Tab. I purchased some programs and games for it, and all was well until it was stolen. The problem? Now I've downloaded and used those same apps on my tf700 Infinity, and the orientation is off by ninety degrees on quite a few. It has to do with Android's API and Honeycomb, and how the default base orientation is set in the framework policy. Before tablets, the default orientation for the Android API was portrait, but tablets made landscape defaults a possible better default. Apps not written to accommodate this would have the sensors read 90 degrees skewed for landscape default devices (like my tf700), because the sensor data is being read from landscape (regardless of orientation), but interpreted as portrait by the app. Even though my Galaxy Tab was a tablet, it's default orientation was portrait, so there was no 90 degre skew. I have read enough to know that it's possible to change the Android system default value, but it has to be changed in the framework . . . No easy task, especially if the rom is ODEXed.
So . . . anyone have any advice or fix so my paid apps aren't wasted money? I don't think emailing every single developer is the key, when I could modify a single system value to fix the problem for all apps. Thanks in advance, any help is appreciated.

Doesnt ever gyro-based app/game have a recalibration setting? Have you tried that?

You could try Ultimate Rotation Control. It can have an individual setting for each application (Forced Portrait/Forced Landscape/Forced Auto).

The problem is that the data the app is getting is from the sensors is rotated 90 degrees. For example, if the app assumes the tilt data it is getting is from the left and right: tilt left, go left. On my tablet, it's default boot state is landscape, so if the app is asking for the sensor info the wrong way (a deprecated way - from before the Honeycomb API), it's getting the tilt axis from the top and bottom, so: tilt up, go left. I can calibrate, but I still have to tilt up to go left.

Sounds like badly programmed apps to me. Have you tried asking the devs to update based on the correct APIs?

I had hoped it would override the default framework, but apps were still polling the sensors wrong no matter which orientation they were displayed in. The sensor data was rotating the same amount as the app, but the original sensor data was still originally off by 90%.
Thanks for the tip; Ultimate Rotation Control is a good app that solved another issue I had, just not this one.

Yes, that's the consensus. Some I've asked, others are no longer in active development (nostalgia for holding onto these apps). I stumbled upon a web hit while googling for answers, the solution was about changing a simple setting in the android framework, but I'm a not experienced with ADB, and things like ODEXing and DeODEXing are nerve-wracking while I learn and experiment.
Also, thanks for coming sbdags. Running Xenogenesis since late April, fantastic job! :good:

Navigate to the androidpolicy\com\android\internal\policy\impl folder and open PhoneWindowManager.smali in your favorite text editor (Notepad++ is my favorite)
Search for the method "rotationfororientation"
(Picture of code here)
Make note of the variables (v#) for portrait and landscape (in my case portrait is v5)
Scroll to the end of the method and you should find something like:
"move v2, v5" (make sure it's the last move command before the end of the method)
Change the second variable (in this case v5) to whatever orientation you wish to be default. In my case I have set portrait as the default orientation.

Dear friends,
As I was also facing the same problem in my Ubislate 7C+(EDGE) tab by DATAWIND. While reading your post an idea struck to my mind. With the help of Root Browser app I navigated to /system/build.prop, opened it in text editor and in "ADDITIONAL_BUILD_PROPERTIES" changed the value of "ro.sf.hwrotation=270" 270 to 180 saved it and rebooted the tablet. Yes! the problem was solved but it created a new problem that the orientation of animation while boot and camera orientation has changed now but in order to rectify it I pulled bootanimation.zip to my computer and after unzipping it changed the orientation of animation files from portrait to landscape. Changed the orientation in 'desc.txt' from 480 800 to 800 400 and zipped both without any compression. Pushed it back to /system/media and changed the permission, user,group to original one with the help of root browser. Then for camera orientation with the help of root browser I navigated to /system/etc/camera.cfg opened it in RB text editor and changed camera orientation from 90 to 0, saved it and rebooted my tablet and now all the games using gsensor tilt are working fine.
Thanks,:good:

[GAME][4.0+] Shape Rotate

Hi guys
I am a software engineering student, eager xda reader and in my (little) free time i like to mess around with my android phone. So i developed a little game over the last half year. It's called Shape Rotate.
I wanted to do a simple but new game, not another flappy bird clone. So finally i put the first version online in the playstore yesterday, here is a short description:
In my game you always see two equal shapes, in random rotations. Your task is to rotate the outer shape so that it is equally aligned to the inner one - once they are aligned equally tap the screen anywhere to get the next one. That sounds easy, but since time is not on your side (you gain some extra time every time you get the two shapes aligned identically) it gets really tricky once the shapes are not that obvious any more. The goal is to survive as long as you can.
It would be really great if you check it out, i would really appreciate feedback (or, even better: positive reviews )
Here is the playstore link: Shape Rotate in google play
It is of course free (no in-app purchases or what-so-ever), and i plan to add a lot more different shapes in the future! I attached some screenshots of the app, and i also added a demo video in the playstore description.

Great game. Has great potential to be a time waster. There does seem to be some lag between the shape changes that can prematurely end your game. Get that timing down and you've hit a home run.
As for some suggestions to add. Maybe have levels to unlock similar to an angry birds setup. In level one hand similar shapes with minimal colors, next thing to unlock, add another shape or two with an additional color. Thus making each level progressively harder.

Thx for your feedback! Regarding the lags, may i ask which device you are using?
I tested it on several devices from an I9000 to my Nexus 4. The only lag i found was that on older devices it takes some time to start the game, but once it displays the first shape i haven't found any lag :s
Yes i already thought about such a thing - creating different "shape packages" and unlocking them time after time. That is definitely a good suggestion for the future and i will soon start working on this. This now is just a first version where i wanted to check out how the game mechanics work and how people react to it.

I'm running on an N4 with KK 4.4.4 and hellscore b47, most kernel settings default.
To be sure I'm understood, I solve one shape and before the transition to the next set of shapes, there is a noticeable pause.

This is a good concept. There’s a lag also when rotating the outer shapes. Though this might be because of my slow samsung galaxy tab.
Overall, this is a good gameplay.

https://docs.google.com/file/d/0B48cqoutz8n3dDFnbTJvRm1XOVU/edit?usp=docslist_api
There should be an mp4 video to illustrate the lag.
Seems there may be an issue with the timer as well.

hm, well it could be that what you think is a lag is actually my poor description and/or implementation?
The playing mechanics should be: you rotate the outer shape so that it is correctly aligned. IF it is so, then you tap anywhere on the screen to "submit" it. if it is correct you get the next shapes.
(The reason why it cannot "auto submit" the moment it is correctly aligned is because then it would be trivial, you would just rotate it until it snaps in - thats why you need that extra "next shape please"-tap)
The possible rotation is actually split into 12 different angles, so there are 11 different angles with which shapes can appear.
The best way to control it is to drag with a finger on the border of the screen (or use two fingers as in normal rotation gestures). you have to drag the finger a bit until the shape snaps in to the next one.
so could it be that it's because i didn't explain the intended controls enough? If so, do you have any suggestions to improve that, or how to better explain the way to play it?
really really appreciating your feedback btw :good:

I may not have read it if you wrote it. When initially testing something like this I go for intuitive. The extra tap isn't.
What about doing the the auto next based on a touch release. You know when the shape is being rotated, the screen is being touched. Can you detect when a finger is removed? There would be no more rotation and wouldn't allow just spinning randomly to get it to snap as you describe.
EDIT:
Looking it up it's called a touch event using MotionEvent class with ACTION_DOWN and ACTION_UP

That is actually a quite interesting suggestion! I tried it out, and it feels kind of nice. it also makes the game easier, maybe i have to reconsider the additional time gain... I created a debug build, would be nice if you would download and try it and tell me what you think ( you have to deinstall the appstore version first, since this one is signed with my local debug key)
It now checks the correct alignment each time you lift your finger from the screen.
Edit: i think that is a gamebreaker because it makes the game way to easy. you just have to swipe very quickly on the border, and due to the "auto" check you always get the alignment correct very quickly.
another version would be this one. here it is also checked on touchUp but if the alignment is wrong it jumps back in the initial state. that makes it even a bit harder, but also requires more focus and looking.
what do you think?

OK, going to leave this one up to you. I didn't catch a difference between the two in how they play. The first one appears to be snappier and jerky, as opposed to the second one being smoother and slower.
Either way, you nailed what I was saying. What do you think? I think this is far more intuitive. Now you just need to figure out the levels of difficulty.
The ultimate would be to have the shapes and colors auto generated with random attributes. You would not have to map anything out, the app would automagically create them.

Ok i found some issues that caused the touch input to be way to sensitive or way to unresponsive - that fixed i got some feedback that the overall control is way better now (especially on high res devices).

I still like the idea, but it brings some new issues that i need to figure out. Once you got the current control mechanism people don't think to much about it - so i'm not quite sure if it is really that much benefit. I will test that out over the next iterations and try gathering more feedback (about the current control and about how much people think it's good/bad).

That is the second big point on my todo list. but i don't really know how to start.
The best way that comes to my mind is to define different "base shapes" that are then just colored randomly. but that again would require alot of different base shapes to keep up a good variety?
at the moment i add hand drawn shapes with each update (around 170 now and using .gif its not that of a size problem anymore)

[APP][OPEN SOURCE][ROOT][5.0+] Night Light (KCAL)

Night light is an open-source app which uses KCAL to adjust blue light intensity of the display colors, so that viewing the screen at dark becomes pleasant for the eyes, and help you fall asleep faster (this is what science have proven so...).
Features
Easy to use user interface. Settings are easier to find.
Uses KCAL to adjust screen RGB colors, hence its efficient and changes are seen everywhere on screen.
Supports older KCAL implementations as well as newer KCAL implementation for v4.4 kernels.
Simple color controls for normal users through color temperature control.
Manual KCAL controls for advanced users.
Automation routines lets you define routines where you specify Night Light settings which you wish to apply, and they will be automatically applied for you in specified times.
Intensity fading in/out is supported as part of automation routines.
Supports sunset/sunrise timings.
Set on boot delay.
Original KCAL settings of user is backed up and applied when night light is turned off. And it can be configured as well.
Support for user profiles, which are collections of settings that user can apply with one click.
And to fulfill your all kinds of automation needs, app is supported as a Tasker plugin. You can use it with Profiles.
Option to automatically disable Night Light in lock screen, and turn it back on after the device is unlocked.
Quick Setting tile for easy toggling on/off night light anywhere.
Launcher icon shortcut for toggling Night Light on/off and toggling intensities.
Dark and Light theme.
Advantages
No overlays.
Background service is only used for lock screen option. The entire automation (including the fading) is done using neat AlarmManager tricks (which not only is battery friendly, but memory friendly as well).
Requirements
Kernel supporting KCAL.
Root access.

Night light is an open-source app which uses KCAL to adjust blue light intensity of the display colors, so that viewing the screen at dark becomes pleasant for the eyes, and help you fall asleep faster (this is what science have proven so...).
Features
Easy one touch toggles, with a single slider to tweak blue light intensity.
Quick Setting tile for easy toggling on/off night light anywhere.
Automatic switching on/off night light at user specifed timings. (Limitation - Start time must be lesser in value than ending time, that is if you choose starting time at 2300 hrs and ending time at 0600 hrs (next day) it won't work for now).
Requirements
Kernel supporting KCAL.
Root access.

The automatic switch doesn't seem to be reliable. Could you add intents so it can be toggled with Tasker? I already have a profile that triggers at sunset so that would be perfect.

Great app, thanks. Have been using CF.lumen until now, but that seems unsupported (and is closed source).
Please keep improving it. Would also like to donate a beer.

Can you explain whats this KCAL thing ??? ??

thanks for this app apreciate it i got ADD and Slightly Autism and i already have an issue sleeping my brain get supercharged and i can't get to sleep but this app helps [email protected]

Loving the app so far, however, I notice it won't trigger at the time I have set unless I manually open the app. I've removed it from Android's battery optimization so I don't think that can be it. Any ideas?

Same here. I forgot to report it. I use Tasker to launch it at sunset & sunrise along with switching between dark / light app themes.

I ended up doing this as well! Now the other thing I'm hoping gets implemented is a smooth transition to the orange hue.

Kcal is a kernel tweak that lets you customize colors at lower (kernel) level, so there won't be any filter or layer on screen, but in most stock kernels it isn't available, so you have to find a custom kernel for your phone/rom that has it.
Thanks for the app, but I've used tasker with the command "echo 180 75 35> /sys/devices/platform/kcal_ctrl.0/kcal" for a long time (echo 256 256 256 > /sys/devices/platform/kcal_ctrl.0/kcal to get the color back.)
Obviously you can change the values to whatever you want.
But the app will be much more easy for many people

I'm using LineageOS with a custom kernel which allows mein to change RGB values from any kernel modification app...

So it should work for you, you can try with a kernel manager like kernel adiutor but the app should work.

I tried the Tasker method and it works great. I had no idea that command existed and could be used in Tasker. Thank you for sharing! :good: :highfive:

Does it fail to trigger if a reboot had happened sometime before the time it should have triggered?
For example, if it was to trigger at 5pm, but a device reboot happened in, say, 3pm, then does it fail to trigger at 5pm?
Anyway, set on boot is broken (again), will need to fix it, but normal timers should work fine.

Ahh, that might be it. I think it stops working after a reboot, so I'd be going back into the app to get it going again.
Very minor issue though, great app - thank you for your hard work!!:highfive:

Launcher shortcut (toggle on/off) switch is also seems somewhat broken, it toggle on but fails to toggle off.

@jineshpatel30 @rickysidhu_
Here is an experimental version (in the attachment of this reply), with launcher shortcut toggle and set on boot fixed.
The reason why it is experimental :
- Now written in kotlin
- Uses some of the new stuff announced in I/O 18, like ktx and the new material design style
- Uses different font called 'Acme'. (Feel free to suggest fonts)
- I decided to ditch cards because normal layouts look better in this new style.

It kicked in automagically at sunset tonight which reminded me to come back and comment. That was unreliable previously.
What does the save button do at the bottom? I assume it saves something, but there's no toast message to acknowledge it's been pressed.
I don't like the font, myself. Since you're going for new and fancy code and styling, why not use ProductSans? I like the new font used in the Wear OS app, I think that's it.
Could you add the numerical values for the sliders for more accurate fine tuning? I like the way the new XDA Navigation Gestures app does it. It's in the latest beta posted in the thread and should be pushed to the Play Store soon.
Since CF.lumen is EOL now, this app is going to be a great alternative especially when it eventually breaks.
Thank you!
