"Optimizing" Nexus Live Wallpaper v0.3 2/10

First, sorry if this is in the wrong section...
...the only stock Live Wallpaper I like is the Nexus, the only thing I hate about it is that it significant lags my G1. So I dug into the LiveWallpapers.apk and made a change so that there are fewer "cells" that fly across the screen. My theory, less "cells" = less processing. Swiping through home screens is a little smoother, and so is opening/closing the app drawer.
What I need help with, is, is it possible to disable the wallpaper following your home screen when you swipe across it? The cells tend to lag when swiping, and for this particular Live Wallpaper, I don't think it's necessary for the wallpaper to follow your swipes.
Here is my .apk. Rename to LiveWallpapers.apk then push to your phone. I pushed it to /data/app_s. It might be different on other ROMs though.(I also zipaligned it, not sure if that will help much either).
v0.3
http://www.mediafire.com/file/hyzwid2rmio/LiveWallpapers-v0.3.apk
Changelog:
- v0.1 -
- Reduced amount of cells in "Nexus" LWP.
- v.0.2
- Reduced the amount of cells even more "Nexus" LWP.
- Cut the length of cell trails in half "Nexus" LWP.
- Increased delay between a cell going offscreen and restarting "Nexus" LWP.
- v.0.3
- Bumped up the amount of cells a tad in the "Nexus" LWP.
- Optimized resolution to better fit screen in Grass LWP.
- Optimized ALL images in LiveWallpaper.apk.
- Resized thumbnails to a smaller size.
- Resized wallpaper for "Water" LWP from 1024x1024 to 640x480
- Made the leaves a tad smaller in the "Water" LWP.
- Reduced the amount of leaves on the screen in the "Water" LWP.

Which dir do you push it to? Ill be the guinea pig because thats the only thing i hate about my WG OpenEclair 2.1 Beta right now. Other then that, everything is gravy but as soon as you put the Nexus live wallpaper on and try to touch the screen or complete any task, it lags miserably.

just pushed it and it really does run smoother. i really dont mind the missing cells moving around. thanks

I guess it's a little better. Maybe even less cells moving around would be okay.

Done, try it out.

I see that other people are getting it pushed just fine. But I am noticing that when I tried to push it it's like it uninstalled all of the live wallpapers and didn't replace any. Any guidance?

care to post screen shots?

It doesnt actually replace any wallpapers. It's just a small tweak the reduces the amount of, lets say, action on the screen. The cells I'm referring to are the colored squares that fly across the screen in the Nexus Live Wallpaper.

How to Push?
ummm yeah how do you push onto g1 again?

Hey Spikey,
I'm away from my pc, but shouldn't I be able to use Root Explorer, mount /data/app_s as RW and copy/replace LiveWallpaper.apk with your updated one?
I'll probably do a nand backup and give it a go for the heck of it.

May I ask which LWP is that cause I never seen that one.
Edit: I see it now, thought it looked different though.This and galaxy have less action than the other ones.

If anyone cares, I was successfully able to mount my /system/app directory as RW with Root Explorer and copy Spikey's LiveWallpapers.apk in. It's working fine and I think it does cut down quite a bit of lag. Thanks Spikey.

The time of day may be the reason for the moon but its 11pm here and I dont see it yet.

There's no artwork for a moon, he added that. Looks nice.
I'll look at the code and see if there's a way to make the nexus paper (actually, all of them) static.

I started to modify livewallpapers.apk
Resize a 512x1024px night.jpg in a fastest 320x480px (g1/g2 size)
then I edited the script grass.rs
at the last I simply added a full moon as background with photoshop cs4.
my apk is 200kb less now =)

I know I got lazy when I worked on those live wallpapers and just left the artwork that size.
I think the artwork actually has to be tall (width at 320 is fine) because it scrolls through the png as the day goes by, it gets gradually darker.
The only one I did any work on was the nexus one to get the "cells" to align correctly to the pyramids. Then I did a revision to fix a problem where the touch registered at the wrong spot, and that was the extent of my work there.
I hope we can figure out a way to get those to run fast.

A little OT
talking about resize, I resized the nexus bootanimation to a 320H px
It's 1mb less now =)

[Q] how do i make boot animation from avi?

i found the coolest thing ever, its avi and almost a minute long. i really want it to become my boot animation, i really dont have any idea how to do it. does anyone have any suggestions for how to get this done? ps - the avi has audio too, and that would be even more awesome to include.

You can create a boot animation from any type of video format even if the format is in flash (swf) what you need is a programs that convert videos to either. Jpg or. PNG file (boot animation can be done using only those two formats) ..... about adding sound to your animation yo need to know if the ROM you are running right now is capable to do audio @ boot if not you wont be able to make it work with sound.
Send from My Draken X

Okay thanks, I'm on it.

only .png picture files

Not sure this is right, I have saved the sequence as jpg images - 1418 of them - to a folder size of 58.4 mb with each image sized 704 X 400. Do they need to match droid x screen size to fill screen? And does my desc.txt really have to be 1418 plus lines? is there an easier way?
Thanks for any help with this, if I can do it I will post it so others might decide to use it.

Wait, what?

the desc.txt file will have max prob 5 lines
my custom boot animation txt looks like this exactly, but yours would prob be a little different
480 480 15
p 1 0 part0
p 0 0 part1
(480 is the width/height; 15 is the fps; 1= #of times that part loops, 0= not freeze on last image of fps unlike the liberty boot animation which would have a 10)
part0 is a folder that contains the images that would be the non looping part, and part1 is the looping pictures folder
the .png is the file extension of the pictures

OH okay I get it. Can the fps be higher? Like 25? And can it not loop? It's like a minute long.
Does the phone start after the boot or when its ready? Like if the boot animation was too long would the phone start without showing it all? And do jpg files not work?

no you dont have to add 1418 of lines create , download one of mine bootanimation and decompress the zip file you see how they work... plus DO NOT USE the NOTEPAD from windows (dont know way but android doesnt like .txt created by this notepad) and download notepad++ from here [url="http://notepad-plus-plus.org/release/5.8.7]Notepad++ (Free)[/url] use that notepad to modified the desc.txt

Okay I think I can do that, going to tackle it after a break.

Okay can't get it to work right. Only plays 2 of the 20 folders, and its choppy. Changed the frame rate to 50 because it played slow. Desc.txt looks like
480 854 50
p 1 0 part0
p 1 0 part1
etc on up to part20
And when it played the aspect ratio was jacked up.
Tried four times.

1450 frames is way to much for a Boot Animation (sorry if i didn't mention that before) max i have run is 390 frames @ 120 an still running very tide to the end, i dont know what app are you using to create you frames but if that app give you the options to make for sample 500 frames out of the clip you have that will be better....from there you can start your testing stage and deleted as many necessary frames to make your animation run smooth
P.S. you don't need to create 20 folders for your animation 1 folder is enought for it, 2 folders is more likely when the 2nd folder contains a loop of the animation in question

Oh. Crap. I read a thread said no more than 3mb per folder. The thing is, I didn't want to loop it.
Let me try this,
Can I make a boot animation that's close to a minute long with an avi as the source, have it play full screen with audio and look good? And if not, how close to what I want can I get?
I'm on apex 1.4.1 and I used avidemux 2.5 to make jpegs from the avi selection.

actually that really doesnt matter cuz i have some animation over 10 MB in a single folder and still working like a charm.....well like i said 2 folders is more like doing a loop out of one of them, having an AVI as boot animation that will be sweet is Google implement that feature in near future on Android using avi, mpg2 or mp4 as boot animation.
i heard (not sure) that Apex CAN run Boot animation with, i have no way to test it cuz im Running Liberty 1.5 (1.75 very soon) ....
P.S. if you want i can help you out with your animation just send me the Link of the video and ill create one and you can have that one as a reference for future animation of yours

well you can have it be a minute long if you want, but i think that is a long time personally, my custom one is pushing 15 seconds and i think it is long. i was told audio doesnt work on liberty rom. the audio must be named "Android_Audio.mp3" without quotes. it is going to be in the same folder on your phone where the bootanimation.zip is kept, /data/local make sure that the audio file is not in the .zip. the desc must contain a line that says "part 0 1 android" also without quotes. btw 1400 frames is not at all recommendable

I could go with it being shorter, and it doesn't have to include audio, but I know it can.

boot animations - should I use png or jpg what's a better decision ?

this is more of a technical question for performance reasons.
.jpg's in my experience can be optimized to be a much smaller file size than a .png.
Granted the quality of the image might suffer a little, but the question here is why would anyone choose .png as their boot animation format since there is no benefit in using the transparency information. Or is there?
Secondly... does the android system somehow process a png animation faster/ smoother than a jpg animation? logic would say no, since the jpg file size is smaller , hence the system can load each frame much faster...yes / no?
One of the biggest issues i have in putting in the effort of making a kick ass boot animation is the loading times due to the large file sequence that it might require...effectively making boot up times logically longer since on top of loading up your system, it also has to load up your boot animation. I find that to be kind of foolish, and defeating the purpose of a boot animation if you know what I mean. Jpg with its optimization options make them a little more ideal for long animations but i want to see what you have to say about all this.

There are quite a few posts out there in this section explaining why pngs over jpg. Look them up, will explain why png format was choose for android. My two cents on this...if the bootanimation is so big that it makes you think about alternate formats...then it probably needs revisited. You wont believe how much you can optimze your file with a combination of lesser images and a different fps in the desc.txt.

k will look them up, but i didn't find anything on this actual subject matter.
I am already aware of the points you mentioned and I am already utilizing them to the best of my knowledge, this is just another point of optimization i want to look into.

Quick question about creating a boot animation

Hey everyone
I just got Cinema 4d and thought id create a boot animation for the TF101 as my first project. My question is how many frames, and what resolution would be the best. Im rendering at the moment 500-600 frames at 1280x800 each and i assume that will end up far to big also what's some good software to convert avi's to .png or .jpeg? (I think cinema 4d does it just havnt got that far)
Cheers

I've been searching for some boot animations, and downloaded a few, and I saw that most have the resolution set to:
Code:
1282x802
although some have it to:
Code:
1280x720
so I don't think the resolution you selected was the ideal xD. About the fps, they ranged between 10 to 40. So your fps I think is too much, but, I'm not really sure of the fps of a boot animation. Sorry .
In terms of the software you want, I've found this:

Hope that helped. Bye.

I have done quite a bit in terms of boot animations and i can say 30fps looks the best anything above that might have skipped frames or trouble loading quickly any lower and it will look jittery. As for res the going 2px above isnt necessarily anymore it was just a honeycomb issue afaik. And a big boot animation will maybe have 200~ frames

Im currently rendering it at 640x400 id like it to be 300 frames because its not really a loopable animation but the file size ends up at like 60mb lol (at 500 frames). I packaged that with the desc file into a bootanimation.zip just to see it working (even if it was slow) but it always ended up playing the default android boot animation would this be because of the size? (Ive never changed the boot animation before)

The naming convention does not matter at all it just does them in order eg a-z 1-99 ect
So it just does not play at all then? Not even a black screen just the old boot animation?

Yeah it wiped the eos boot animation that was in system/media and now plays the animation with the gray "android" which some reflections on it
my new bootanimation.zip is 25.9 mb at 222 frames the images are all .pngs named android 001 to android 222

Ah that is strange, Im uploading it now (I made it for RaymanFX's rom) but its still 69 mb, how can i get it smaller it had been rendered at 640x400 at 42 dpi at 500 frames (It still plays fine though)

here's a link to it if anyone's interested (https://dl.dropbox.com/u/39805348/Boot Animation/bootanimation.zip) (still 69mb) it would be good to get some opinions on how to make it better

Bootanimation

Is there any way to make a bootanimation landscape and with sound ? I have tried and tried to figure it out and can't get it to do either. Well in lollipop at least. I did have cloudy with a bootanimation but not landscape and it had sound. I am completely stumped. I have a certain theme I am doing with my device and to have the boot animation to be landscape and with sound would complete my project. Any help would be greatly appreciated.

I can't recall if I've installed a custom boot anim in L yet... I think I have. I hope I get your question.
But just create the animation content (foreground) rotated 90 degrees (landscape for the foreground), leaving the background OEM (height and width). It should run perfectly.
The sound file is a separate sound file (ogg)

How do you rotate it ? Do you do it within the zip ?

Effectively you are creating an animated 'gif', in a manner. If I take Photoshop as the example:
check out this as an example.
http://www.online-tech-tips.com/computer-tips/create-animated-gifs-images-using-photoshop-cs6/ or an editor of your choice.
and this guys tutorial
http://forums.androidcentral.com/ac...ions-collection-tutorial-updated-10-19-a.html
You will create you background at the resolution (1080 W x 1920 H shutdown animation, boot animation full HD 1440 W x 2560 H are common resolutions for the G3) you wish for the animation, say solid black or what ever.
If you fully create your own, you will first set up the resolution and make your background color, then rotate the base image. Then create layers for each frame/cell of your animation. As you already rotated you base image to landscape, your layers will also be in landscape. Then copy each cell into a layer.
Create the animation, save each frame out as a jpg, create the desc.txt file, and zip it up, install (renaming your OEM animation to save them, and set permissions 644.
Following the guys tutorial, you can download animations, and deconstruct them, using parts as you wish.
Good luck.

I'm making my own Mortal kombat bootamimation from new game coming out. I have it full screen with a boot animation tool I found but can get poweron.ogg to play sound upon boot on lollipop candy5 ... Placed it in system/media/audio/ui but it is a no go.... With so7nd it would be soooo sick.
But I'll check out the links you gave me so maybe I get get it I'm landscaped instead of this full screen portrait cause it does look a little wonky
