I rarely use Live wallpaper in a battery sake but for Christams I love animated Live wallpapers with snow and lights, I still have 2 of them from last year (Nexus 1) and I think both use OpenGL engine, they look both good on the qHD screen while it was tailor made for 480x800 screens.Now my question is:
-Do they look ok because the pixel resizing is not huge? or because it's in ''3d'' resolution is adaptive thanks to OpenGL??
If it's the first choice so we should get better results if they do qHD version

Read a post today regarding why Android phones are so much bigger than the iPhone and it makes my blood boiled:
http://www.displayblog.com/2012/01/16/why-android-smartphones-are-bigger-than-the-iphone/
If he was true, I wouldn't complain. But that guy totally made things up by himself. It's clear that he had not done research to back up his "theory" -- he just made it up himself. Any Android users who had changed the LCD density of their devices would know that it's fairly easy to change the lppi. When a manufacturer increase the physical resolution of its device, it will adjust the LCD density to accommodate the denser display. That guy could find out the truth easily by asking around.
The article makes perfect sense to me. I for one would much rather have a smaller screen with higher pixel density.
does it really matter. you have a device and it works for you, if you read every post where somebody whines about the most trivial things then i feel sorry for you. get a life
I think I'll try to rebut this.
There are four DPI levels (MDPI is baseline):
LDPI: ~120DPI
MDPI: ~160DPI
HDPI: ~240DPI
XHDPI: ~320DPI
What this means is that when resolution increases from ~120 ppi (I prefer ppi when discussing pixel-based digital displays) to ~159 ppi fonts and icons will get smaller. This applies to all three levels of in-betweens. And displays north of ~320 ppi will continue to get smaller with no reprieve.

True. But manufacturers do not create screen sizes of EVERY possible density. They tend to aim for a certain density. And I don't see why they won't round up 159ppi up to 160. They wouldn't (with minor exceptions) create a screen perfectly at the middle between HDPI and MDPI, for example.
If displays size were kept at 3.2 inches from the G1, the corresponding resolutions (ppi) would be:
G1: 180.23
Nexus One: 291.55
Nexus S: 233.24
Galaxy Nexus: 458.94

Why would you want to convert the screen sizes to 3.2 inches first? This doesn't make sense! Oh, and I think you calculated the Nexus S wrongly.
But because Android renders text and graphics like desktop OSes (e.g. Windows, OS X) increasing resolution above 320 ppi means smaller UI elements. The display had to grow in size to compensate for shrinking UI elements. iOS renders the Retina display not by shrinking UI elements by one fourth but by doubling clarity and sharpness. Unless Google adds an additional “DPI level” beyond XHDPI, Android smartphones that match or beat the iPhone 4/4S in resolution will always be bigger, much bigger.

Android would never need to go past 320dpi, just like the iPhone, for it is at the verge of the human eye's visual acuity.
FYI for those who don't know, 4 copies of the UI elements are created, for each of the different display densities. So scaling up would simply mean swapping the element with the identical one of the higher density. Anything past the highest density is also past 320dpi, higher than the limit the human eye can distinguish.
UI elements created for XHDPI are usually purposefully created such that they are big enough for the density, allowing UI elements to be comfortably big enough for users.
Then why are 1280×720 Android smartphones much bigger? Because UI elements would get too small if they were much smaller than 4.5 inches.

There is no point of having a screen higher than 320dpi. It would be hard for one to differentiate a screen of 320dpi and 360dpi of the same size. There is no point in google trying to compete in resolution with the iPhone at this point. And besides, a manufacturer could easily release a 3.5 inch phone matching the iPhone's screen perfectly with no problems.
So there is seriously no practical point in trying to squeeze 1280x720 into a small 3.5 inch screen. I doubt manufacturers will want to try that when a 320ppi screen could do the exact same job (which by calculations, a 960x640 screen fits perfectly), without users noticing any difference. This is when resolution does not mean everything. DPI is much more important than resolution.
Disclaimer: I am not an app developer, but this is what I understand from the documentation from the android developer website.

If what he said was true, then it made perfect sense. The problem is, he's wrong, completely. An OEM will change the ro.sf.lcd_density in build.prop to adjust the LCD density so that the font size and icon size scale up as the physical resolution increase, period. That's a fact and I have not seen a single OEM who doesn't do that. In fact, if an end user roots his device, he can change the setting himself.
No offensive to the iOS fans, but I just couldn't stand for some of them who think they know everything and keep inventing new things to praise how great their OS is, when they couldn't even get the fact right. I mean, if he's saying a 3.5" screen is the perfect size, that's one thing because it's personal preference and no one can argue that. But he wasn't doing that. He just made up a theory that is just plain wrong and present it as a fact.
Hey I'm new to ICS and this kinda stuff, what is the best size or app for background images to used/make if i want them as crisp and best looking as possible without too much cropping? It looks like I need a square kind of image but isn't the homescreen 702p (1280x720) aka not square? :/ I don't get it! help!
This should be posted in Themes. Could you move this please? The general is starting to become extremely cluttered.

Your question is a little confusing to me, but if I understand correctly, you want to create a wallpaper to use on your One XL (ATT + Rogers X). If so, make it at the full resolution of the screen.
There are also scenes though, that will pan left/right depending on how you scroll through your home screen. I'm not too certain of these resolutions, but if you keep the height the same (720px) and play with the width, it may just pan in different increments depending on the width.
Good luck,
~dan
i have no idea what rogers xl is...but i just bought this htc one x stock rom etc non rooter(don't know how) from my phone company simlock free etc...so no extra software for my phone company ....and I do want to know what the best aspect ratio/res is for pictures without zooming, i have 7 home screen but whenever i add a pic 1280x720 on my gallery(via SD -->usb) and select the picture and do ''set as...-->wallpaper'' I have to crop it too something that almost looks like a square...but I am not sure! and if I crop it the picture become blurry and ugly (at least that's from my experience...)
You need to double the width of the wallpaper, so for a 720P screen (AKA: 1280x720), your wallpaper should be 1280 pixels tall x 1440 pixels wide. For a 800x480 screen, the wallpaper should be 800 pixels tall x 960 pixels wide... And so on.
Hope that helps.
I want to develop a text driven, mystery game for Android. The art will be in the style of a graphic novel. I'd like to be able to support as many devices as possible. I understand that Android can scale the graphics for different screen sizes, but an image produced in 480x800 would look like crap on tablet screen. What is the best way to deal with this problem? Is the solution simply to produce images for all screen sizes I want to support? This seems like the most effective way, but would make the app way too big. Can the image simply be produced at a very high resolution and shrunk down or does that cause problems? Thanks for your time.
In my opininion the best pictures will be HD or qHD.
This size is very good for big screen, and will be good resize for small screen.

What do you mean by HD or qHD? Can you be more specific? Do you mean 1920x1080 for HD and 960x540 for qHD? Will I be ok as long as I stick by the 16:9 ratio?
Yes it is this size : )
More phones have 16;9 screen, that I think it's the best way to good game graphic:good:
Is this something you've seen in your own tests or did you read it somewhere? I'd like more documentation on this before I start producing art.
hi everyone
I need to ask something that i was unable to find answer on internet or Google searching. I come straight to the point. It's basically a general thing about devices that i found different in aspect of screen resolution and i couldn't find difference.
There is one Android device which gives resolution of 540*960 on a 5inch LCD and there is an Android phone which gives 1080*1920 resolution on 5.1 inch LCD like S5 AND 1440*2560 resolution on 5.1 inch LCD.
I want to ask what is the difference that these resolution gives, i am currently using 540*960 resolution phone and what difference i would note by using 1080*1920 resolution? will thing appear small on it?
For example on a home screen, i have a gadget of weather, will it appear more smaller? because i didn't get the difference of resolution and their result difference.

firstly i can guess by the post that you are a noob but would like to help you change to pro so here it goes
the difference are
420*320 and below ldpi-small- 2-3inches - packed with 100 to 150 ppi screen
470*320and below IS mdpi - normal- 3 to 4.2 inches - packed with upto 200ppi
640*480and up IS hdpi- large-4.2 to 7 inches - packed with 200 to 300ppi
920x720and up IS qhdpi- extra large- more than 7 inches - packed with >300ppi
if that's unclear to you
try searching up screen support on google or api guidelines
if i helped hit that thanks meter

i am sorry if i sounded noob but i was unaware of these things. I was just wondering what's the difference of resolutions when the screen size is same.
From your post what i got was, that it is basically the PPI thing, which makes screen more bright and colorful etc. so more PPI is based on more resolution or pixels.
I am currently using Huawei G610s and it has 640*480 with 220ppi. I thought that resolution is same as in case of computers, the more resolution the more smaller the pixel and picture size and more desktop area. I am currently using 1680*1050. So i thought in same context and was wondering and thought to ask.

firstly ppi refers to the pixels per inch
it in simple words is how tightly pixels are packed in a sq inch of area on the screen . the more the ppi count the smaller each pixel gets providing you with sharper and intense quality display
also if you did not search api guidelines on google
i am here to help you
here go ahead and just go through the detailed version and i think it will solve almost all of your query

don't forget to hit thanks :good:
Now. Don't get concerned on how you sound. We were all like that at some point. The resolution that you have probably is around 200 DPI (depending on screen size) My phone (Xperia SP) has a 4.6 inch 1024 x 720 display AKA 720p display. In person, how they look actually matters. Anything above 300ppi is crisp and extremely sharp. A Samsung galaxy s5 has a PPI of around 400. These numbers don't really matter but if you see them in person, they really look nice. Hope I helped you.

Hi all, I have been a lurker here for many years but thought i'd make my first post to ask a question regarding the display and wallpapers on my brand new S6 (which I love)
So I'm fully aware of the theory that true black wallpapers will save battery life, so I decided to create my own wallpaper and try it out. But the question is do I create the black image using 1440 x 2560 pixels (the S6 resolution) or maybe a smaller image using the same aspect ratio, say 50% smaller so the phone will resize the image to fit the screen? Does anyone know if the smaller image size would have benefits memory and battery wise over a image that uses the same native size of the S6s screen resolution? Would using PNG over JPG or GIF require more memory as PNG is considered almost lossless? Would it produce an image that is considered more 'true black' over JPG where artifacts can mess with colours more?
I think i'll conduct some tests and find out over the weekend but interested in other people's opinion.
