Polar Clock is not broken

Polar Clock works, but the dynamic color palettes force crash. Here's how to fix: http://www.youtube.com/watch?v=9xAOehuxsYQ
sorry it's so blurry, had to film it on my old G1. Shouldn't be a problem henceforth

Does anyone know why the dynamic palletes FC it?

Unfortunately we can only guess as to the problem (and fix it) until the source for 2.1 is released. According to the logs, it fails with an ArrayIndexOutOfBoundsException, which says to me it happened because of a quick source code change that didn't get tested well enough.
Although I am curious to see what's so fancy about the dynamic polar clocks.
Edit: Fun! I'm sure I'm spending way too much time with this, but I'm enjoying myself, so nyah! Anyway, it will work fine next month. All the way up until January 2011. Which I was expecting, with the Array OOB Exception, in the getMonthColor class...
Anyway, the rings change color depending on the date. So the second (minute/60) ring changes color as it walks around the outside of the ring, as does the minute and so on. Although the second ring is more obvious, because it moves faster! Polar Bear has bright colors with a white background, and Black Hole has dark colors with a black background.
So next month your dynamic polar clock shall be working very nicely for you! Although one would hope that they release the source code before then, and that this silly bug is fixed in the official source at that time.
Ohh! If you want to see it, go into settings and turn off the automatic date & time settings, then change the date to sometime not in January. I also had to turn on Airplane Mode, or it would keep changing back to the actual date.

Nice. I want to see what they look like, but don't feel like fiddling with the time/date just to see it.... lol. Guess I'll just wait.

I didn't have to alter my time/date at all. I simply changed the colour palette to iron and left it. Thus far, 2 hours into doing so, polar clock has not crashed yet.

Well, technically is it broken where the dyanmic colors don't work. I wouldn't mind seeing the polar white on my screen than that crazy fruit color! LOL I sort of the like the grass personally...as the day changes so does it...nice!

iron polar clock looks great with the black bar theme, so the limitation isn't a big deal to me.

Nice to have the polar clock finally running, but I would love to see the dynamic palattes. I'll just wait for now though.

[UPDATED] An opengl ES 2.0 livewallpaper - Space Chase

Hello world,
here's a demo i wrote to test the opengl es 2.0 ndk code.
i plan to make it a real wallpaper with options, but if you want to test it, here's the apk
--EDIT
apk updated to the beta version.
i'm gonna sell this on the market, but i give a free beta to xda members
just a quick view of the features :
-adjust star speed, size, density, rotation
-double tap to engage hyperspace
-single tap to fire
-auto fire mode
-change craft after each hyperspace
- 8 crafts so far (x-wing,y-wing,tie-fighter,tie-advanced,tie-bomber,tie-vader,millenium falcon,tyridium shuttle)
-auto hyperspace after 25 laser shots
-customizable laser color
and maybe a few more, it's late and i don't remember everything.
Oh i forgot to mention, it's almost all native code, using glsl shaders, so it should be verry cool with the cpu (but not the gpu )

Wow. Well done man. Looking great, can't wait to see the end result. Keep on keeping on.

That's pretty awesome. Looks like Star Wars hyperspace. Just missing a tilting Millennium Falcon in the foreground.

i was planning a X-wing

Will we get to see a random transition in and out of hyperspace?

Works pretty well, there are some stutters when switching orientation

Seriously good job. My stomach started to turn after a few seconds, but that kind of stuff always gets me a bit sick to my stomach and really means you did some fantastic work.

Impressive. Swiping is still very fluid. It needs slowing down and probably other options but I expect you have those in mind. Can't wait to see a 'finished' version

This is gonna be great im going to keep an eye on this!

Nice. So glad I went for Droid instead of the TP2 I wanted.

Sweet i can't wait

Oh my god!! It`s incredible... Keep on going man.
I want to see this in my homescreen all the time under my icons and widgets!
It`s amazing...

I forgot to mention that the apk contains an activity and à live wallpaper, you can already have it behind your icons

Thankyou guy. Simply I have not search in the live wallpapers picker. It`s
awesome to see this in the desktop without slowing down so much. Keep the
good work.
Thank`s for all.

Nice one. The ability to set the speed would be nice.
Shows 0% cpu usage with SeePU, vmstat shows an average 22% user-cpu usage, 0% in sleep mode.

well, i worked a bit on this one and it became something
i've updated the attached apk to the first post.
i will sell this on the market but i give xda members a free beta.
the craft tilting is a bit too nervous so far, and it lacks a few setting, but it is close from it final version.
just let me know if you like it

remove spaceship
hey, i think u did a great job with that wallpaper, i just have a little suggestion, is it possible to add the option to remove the spaceship? keep it up!

yes, it is already in the full version

uff..got FC...and loop at reboot.
Maybe because of my test2&mods...
Nevermind,nandroid..
Edit: sorry, it wasn´t your livewallpaper that caused the trouble, but I put Wysie´s mod and TA Pro new patch together, this caused the loop!
Edit: Awesome Livewallpaper!!!

Wow, this actually works and looks great on the Droid. Very smooth.

[APP] [Live Wallpaper] Motion Timer Live Wallpaper

Hi everyone,
I've put my first app up on the market:
https://market.android.com/details?id=org.anddev.wallpaper.motion.timer
Here is the youtube video:
http://www.youtube.com/watch?v=jfADhuBjdnA
I would really appreciate everyone's feedback and impressions!
Cheers,
-=JK=-

I can´t watch the Video, because EMI has block this ?

Darn ... didn't realise how restricted that would be with a soundtrack on it.
Here's a video with no sound track:
http://www.youtube.com/watch?v=JewxFD-zp3E
-=JK=-

Installed it and then set as wallpaper but no balls are displayed. Also there are no settings on the wallpaper. Am i missing something here?

Very cool looking...what happens if you shake it? =)
- Sent from my Motorola Atrix 4G -

Xee,
You should see some balls appear when you tap the screen.
When you get 32 balls on the screen subsequent taps cause mini-explosions.
It's a very simple wallpaper, so no settings yet. I might find something to set when I update it.
Obartuckc,
At the moment, nothing happens when you shake it
It responds to the accelerometer by changing the direction of gravity on all the balls.
I could look into triggering something on a shake ... what would you like it to do?
Cheers,
-=JK=-

I like what you've done with it thus far, whatever you do can only make it more awesome! I really like how if you add a new ball on top of others they sort of fling out...perhaps shaking it could make them pop or sort of explode? That'd be neat. Whatever you decide, keep up the good work!
- Sent from my Motorola Atrix 4G -

this totally reminds me of those liquid motion desk toys...
that's a live wallpaper i would like

That's great to hear PatcheZ!
That's exactly the feel I was going for.
I'm hoping to figure out a way to extend to something like these: http://www.officeplayground.com/Liquid-Motion-C23.aspx
It'll be a solid body physics sim until something as great as http://www.box2d.org/ comes along for fluids.
Cheers,
-=JK=-

Man, you got balls.

nice job with this

Thanks for the comments.
-=JK=-

I would've loved to see the video, but apparently you've used some music from EMI and they've blocked the video because of it. Could you reupload it without the (alleged) copyright infringing music track?

TheCreat,
Sorry about that. There is a link in the video description to this version which has no music:
http://www.youtube.com/watch?v=JewxFD-zp3E
Hope you enjoy.
Cheers,
-=JK=-

This is a really cool wallpaper, thanks.

Very Nice, but once all of the balls have reached the top or bottom of the screen there is nothing going on.
Could the ball toggle their state after they have been at the top or bottom a certain amount of time?
For example: after a blue dropper is at the bottom for x seconds, it becomes a green floater and floats upwards and vice versa.

Thanks for the feedback guys, great to hear.
Spauldio,
When you change homescreens the gravity should switch ... which will make all the balls start to fall and float again!
Cheers,
-=JK=-
PS - I'm using the onOffsetsChanged method to accmplish this behaviour - http://developer.android.com/reference/android/service/wallpaper/WallpaperService.Engine.html#onOffsetsChanged(float, float, float, float, int, int)
- but it seems a little inconsistent in when it's called ... sometimes called on "half" changes to the homescreen. Haven't been able to figure out how to make it robust ... I just switch the gravity flag when it's called.

Version 1.1 !!!
Updated to version 1.1
I've kind of combined suggestions from Obartuckc and Spauldio. I've added a shake control, so that when you shake it gravity is switched and the balls all start flowing up and down again.
Hope this goes down well
Cheers,
-=JK=-

Hey, just installed this, it's great! But how's battery life?

Thanks NickHu!
I haven't noticed any difference in battery usage to previous live wallpapers I have used.
Is there some benchmark I can use to gauge battery usage of my app?

[APP] [LWP] Smoke Play beta

Hi all,
My second app is up on the marketplace:
https://market.android.com/details?id=ph.android.smokeLWP
It's a fluid solver driven live wallpaper and stand-alone app.
The effect is a simple but satisfying dynamic smoke.
Youtube video to follow tomorrow.
I would really appreciate your feedback and feature requests!
Cheers,
-=JK=-

My sgs2 is smoking!
Impressions are good, although with a blank initial screen, thought something was wrong until I touched it...(Duh I know).
A wee bit pixilated but understand the universal performance issue, which would slow most devices dramatically If at a higher resolution.
It reminds me of a app called Fleya, which is on the market, if you are not familiar with it, check it out.
But this is a great start, and being a fan of fluid / smoke dynamic simulations, this is a keeper
Will be following this.
Well done and thanks.
Regards

With reference to the "Fleya" app for reference.
www.appbrain.com/app/fleya/fixedpointcode.fleya
Cheers

Thanks buzzboy.
Yeah, I am also a fan of fleya!
I've got quite a lot to add to Smoke Play to get it to where I want it. I've been messing around with some settings and superficial stuff for about a week so I thought it just needs to get out there.
My ideas for features are:
a settings activity where you can up the detail and iterations on the fluid solver for more powerful phones
expose all the smoke (or fluid) properties to be customisable
define some cool pre-sets
coloured smoke that mixes (have this working on my laptop)
continuous auto-sources of smoke
objects (draw shapes) in the path of the smoke
calculated objects field from the homescreen icons (smoke collides with your icons)
an auto-config activity which scales the detail up or down to optimise quality on all phones
maybe put an ad in the settings activity
I'm not sure what order I'll do things in. I think some sort of settings screen will be up next.
I'm keen to hear other ideas too!
Cheers,
-=JK=-

Just made an update, check it out!
Added features:
- smoothed the input
- added multitouch
- added a settings screen to make the level of detail user configurable
The "medium" level of detail is about right for my SGS ... so you can judge the right setting for your phone.
Cheers,
-=JK=-

Another update:
- tweaked the settings for the different levels of detail smoke
- fixed a memory usage bug (will keep an eye on this, difficult to reproduce)
Cheers,

Nice, runs at very high on my DHD, nice work.
Sent from HydrOG3N MOD DHD.
Technology Evolves, Android Evolves.
HydrOG3N is THE Revolution.

Real smooth on my echo, nice work

This is very entertaining. I am looking forward to the features you want to implement.
How about accelerometer detection so the smoke rises accordingly, depending on how the phone is being held.

I wallpaper works in the preview mode but will not apply to homescreen. One suggestion I can think of is being able to change the background image. It would be awesome to be able to have a weed background with dynamic smoke
Sent from my Hero CDMA using XDA App

This wallpaper is amazing. The only thing it really needs is a certain amount of smoke as a sort of baseline so that I don't have a blank phone every time I wake it up. It is pretty nifty that the screen comes alive the first time you touch it though..

Nice!
Working great on my SGS running on High detail. Very nice work!
Hope to see implementation of accelerometer and colors.

Thanks for the feedback everyone, great to hear!
I wanted to make more updates, but I've been a bit tight for time recently. Some of the feedback I've had is that it looks pixelated so I've been unsuccessfully trying to work on a simple shader to smooth the rendering. I may not be able to make this work, but I'd like to. For those interested, the fluid sim uses C code via the NDK so this may be complicating things for me ... also shaders will not work below Android 2.2 which adds complication.
Colour is definitely coming, I have this working with a simple RGB colours in my test code. I want a nice way to choose colours in the settings screen. Any suggestions around this would be cool.
Accelerometer detection will come, but this will be slightly more tricky than colour and may take me a little time.
A constant source of some smoke (so there is something always on the screen) will be a later addition.
I haven't looked at transparency over a background image yet.
Cheers,
-=JK=-

i love this man its very nice. the updates you want to do are sounding great too! one thing i do want to add is an idea for it. maybe when you get the constant smoke source try having so your touches dont always produce smoke but can just twirl it and influence it. like have a setting where you can turn on constant smoke and then play with it. But its great so far keep up the work!

Hi Guys,
Got an update out! (finally)
This one includes:
- a bug fix of a known issue in OpenGL which was causing a crash when switching between the app and the wallpaper every now and then
- a smoothing renderer. This takes the edges off the pixelated look which was the main feedback I was getting.
I went down and back several paths to try and smooth the rendering. I'm fairly happy with it. The levels of detail for the fluid simulation are the same as before, but it divides each cell into 4 and does a sort of subtle bloom effect prior to the gl rendering calls.
Hope this improves the look and feel for people.
I looked at porting to OpenGL ES 2.0 (from 1.0), but it was just too difficult for what I was doing. If anyone knows a good tutorial to do this I may look into it in the future. I think the shader effects available in 2.0 would further improve / customise the visuals.
Cheers,
-=JK=-
PS - next up: accelerometer (then coloured smoke / constant sources)

New version out today!
Accelerometer detection for the smoke rising added.
Also slightly improved the rendering performance.
Finally got around to filming it too, here's a video:
http://www.youtube.com/watch?v=8xdLceg474k
Cheers,
-=JK=-

Version 1.8 up on the market.
Added continuous source mode: smoke is continuously added to the middle of the screen, swipe to push it around with forces.
Added simple colour: cycles through RGB when you touch the screen.
Next up: background image, colour picker.
Cheers,
-=JK=-

Thanks for sharing.
As an FYI, the smoke is pixelated on my Archos 70 :
I'm using the latest market version with "smooth rendering" enabled.

Hi jknut,
I'm sorry it's pixelated on your device.
You can try upping the smoke level of detail in the options.
Unfortunately, this will increase the number of calculations per frame and may slow it down to a crawl.
There's not a lot I can do about this ... the algorithm is implemented in C via the NDK so it's not going to get much faster. I have implemented a fixed point version which gave a slight speed increase but unacceptable precision for the effect.
Even on my Core i5 laptop I can easily make it grind to a halt on a detail setting not much more than the "are you feeling lucky" one.
Cheers,
-=JK=-
PS - more features to follow, just swamped with work right now

Version 1.9!
Hi all,
New version just released.
Features added:
- colour picker, so you can choose your own colours
- background images you can pick

[APP][TESTERS NEEDED] Notch Battery Bar - Live Wallpaper

Use your notch as a battery bar in this live wallpaper.
I need someone to test this app on the Essential Phone. So if you install the trial version on the phone, adjust the size and post a picture(not a screenshot), I will give away pro version codes for the first 3 people.
Trial - Play store link
Paid - customizable - Play store link

Looks pretty awful, since it's designed for wide notches and we only got a "drop" of a notch...
Width: 200
Height: 150

Used settings:
Width: 220
Height: 160

After applying size adjustments to app, nothing happens.. all I see is the wallpaper, and the app wants me to change 5he wallpaper as well?
This is a very creative app; appreciate the ongoing work for this ?

Please give me code too.
210x155

I tried your app with a bunch of different settings to try to get one that works well with this phone.
width 170
height 129
Seems to work best for me.
One issue I have with it is the angle of the slope.
Is there any way you could simply make the highlighting properly follow the curve of the notch for this phone, rather than spread out (thicker) at the top and around the bend (bottom). FYI: I could never see the color band below the notch (as shown in your video for other phones).
Also, there should be a way to visualize any changes you make rather than going pixel by pixel to try to get to the perfect setting for your phone. --> Hit apply. --> Hit back. --> Hit preview. --> Realizing you have to change it again and again. --> Hit back. --> Hit edit. Change #s. --> Repeat.
Simply too many steps.
My guess is that the average user takes 10-15 tries to get to the correct-ish numbers for their specific device.
Suggestion:
I know it's a lot of work with so many phones, but maybe a submission key / option so you can begin to collect preset ranges that people are using for the most common phones.
Question:
Is there any way to implement this so that it overlays when you are using another app. Right now, it only shows on the home screen (wallpaper only).
Because of this, I can't use muzei
If you can do this, I'll happily buy it.
------
Feel free to PM a code if these suggestions are useful.

You have to hit preview to see the changes.

Interesting app. I just previewed the trial. I need to play a bit with the sizing though. I'm a little disappointed this is a live wallpaper though. I'd like to use a different live wallpaper. Is there no way to use this as an overlay or something, even with root?

If you buy the app it let's you change the wallpaper

Yes, we cannot use 2 live wallpapers at the same time. And the wallpaper needs to be live otherwise it wont be able to update itself.
