Hey folks,
Not sure if anyone knew this, but felt I needed to share in case someone was struggling with this.
I was trying to change my wallpaper to this cool one (http://picasaweb.google.com/106634558980524885375/Android#5510327223138403954) I found from a member of another Droid X site. I forget the owners tag, my apologies.
Anyway, I wanted to view neary the entire image as my background, but when going to Media Gallery it kept displaying an orange box that didn't allow me to select the full focus of the image. So, I tried resize the image 5 ways to sunday so I could see nealry the full image. No good.
So as I was resigning myself to the alloted small focus area, I, by chance placed both my thumbs on the orange boxes edges and it changed to allow re-sizing of that box!
Now I view the more interesting sections of the image and still allow the scrolling between desktops.

I just downloaded a map from Sugarbush Ski mountain in Vermont so I'd have it handy when skiing there. Unfortunately, when I zoom in the image is so blurry that I can't really read the text. The same map looks fine on my desktop computer.
Unfortunately I can't post a link to the map because the XDA developer's site won't allow me to (you can't post links until you've made 5 other posts to the forum). Just google 'Sugarbush' and you will be able to find the static trail map image. Someone else who's been around here longer could post the link in a follow up message.
I've tried viewing it in multiple programs (standard browser, Dolphin browser, gallery view), and all show the same problem.
Can other Nexus one owners confirm that they have the same issue?
Any suggestions?
I think android might downsize/downconvert images automatically so you will not be getting the original resolution of the image.
UPDATE:I can confirm that the image is definitely lower resolution than the one that appears on desktop. Here is the link:

I just mounted my Nexus via USB and checked the file that I'd downloaded to it. The actual file stored on the Nexus One is full resolution and displays fine on the PC. It's just on the Nexus that it fails to display well.
This seems more like a bug then a feature.
I just made a simple 2000x1000 graphic with two strings of text, one aliased and the other antialiased with a crosshatched background.

You can clearly see how blurry both lines of text and the crosshatches are when you zoom in on the android browser or in the gallery. It looks like there is either a huge amount of compression being applied to the image, or that the image is being resized for viewing and the blur effect is due to a loss of detail that you don't get back when you zoom in.
I don't know if imageshack has a bandwidth limit, but here is the same image on imgur.com. You can see the extra effects of blurring, though you also see a lot of jpeg artifacting from the high compression imgur apparently automatically applies.

* sorry for the broken links. Despite having joined 2+ years ago, my low post count prevents me from posting urls. If anyone else can repost those links as real urls, it would be great.
I've been searching, and have seen lots of threads about similar problems with the Evo and it's fairly low-color screen, but I was under the impression that the Droid X has a 24bit color screen so this shouldn't be an issue.
Anyway, I've got some wallpapers (cropped and resized for the Droix X from the originals at Ultralinx)
They look fantastic on the computer. They're the right dimensions. Tried saving as JPG and 24 bit PNG, but the outcome is the same. When I copy them to the phone and set them as wallpaper, the gradients don't look smooth; there is color banding all over the place.
I've got screenshots and originals up on the web, but can't link to them until my account is approved by a mod.
EDIT: Added attachments instead, but the forum super-compressing the images doesn't help their clarity at all.
Hey,
i've got the same problem.
That's not funny at all, I really don't know how to save it, that it looks like on my desktop pc!

Sorry to be off topic but I cant help but stare at your notification bar. What theme is it?
It's my own notificationbar.
Have to search the files first
It doesn't seem to be the screen. I dropped those images into my dropbox, and opened them in whatever viewer dropbox opened by default. The image was smooth as I zoomed in, until I zoomed in far enough to see a moire pattern. I also opened it in Astra's built in viewer; again there was no banding. However, when I set the image to be my wallpaper, I see the same banding you are seeing.
Bad news is, I don't know what the problem is; good news is it doesn't seem to be a screen limitation.
Thanks so far!
But what's the problem than?
I really have no idea :/
Ah ha! Google turned up this app: "Wallpaper Set and Save" (Sorry, can't post a link because I'm new, apparently. I attached an image of the QR code instead.)
It says it hasn't been updated for 2.x, but it worked fine on my droid x (running the stock rom with launcher pro.) Using it to set the exact same wallpaper, I now see no banding (although I did in the preview screen.) It's worth a try, although I'd still like to know what is causing this issue (since it obviously isn't a hardware issue.)
I attached a screen capture so you can see for yourself.
Edit: The forum's image compression adds some artifacts; it looks even smoother on my screen capture. Even here it's a big improvement over the others though!
Its probably the gallery app that is re-compressing the wallpaper and creating the bands
I am a noob to developing and was wondering if anyone can give me a good start at creating a Live Wallpaper.
In my head its quite simple.
i have a set of Pictures from a bootanimation.zip i use.
i want the screen to show the first image until i touch it. then i want it to cycle through 2 sets of images, finally replaying the 2nd set until touched again, then go back to the first image...
anyone think you can help me out with that?
thanks...
and in case anyone is wondering im trying to make a stargate live wallpaper, that activates and deactivates on touch.
I an on my phone so I will comment more later. But you should first check out the cube live wallpaper in the samples. Since it is a working example it so should be a good place to start. After looking through the example take a look at the official docs to see what everything is doing.

Hey,
I'm new to android dev (extremely) but I'm not new to software dev, but I'm very confused.
So here's my end objective: To capture a photo and be able to edit it at the pixel level.
I'm completely lost in how to do that. Okay, let me rephrase, not completely lost. PLEASE don't link me to a bunch of tutorials, I've read them all.
I'm lost on a few apparently key concepts:
- SurfaceView - What exactly IS a surface? I read the doc from android dev for it, but I'm not quite grasping it. Is it just used to display or subclass it for OpenGL, or picture viewports? Or is there more to it?
- Every camera tutorial mentions subclassing surface.holder, implementing canvas methods methods (changed, create, destroyed), and that's that - which is fine, if you're going to preview an image there, which I want...but what about taking the actual picture, that leads me to..
- StartPreview function, what the hell does this thing do, all it does is crash my phone, I don't want to "preview" anything, I want to take a picture using the built in camera activity, and store in a surface, do whatever pixel manipulations I need, and possibly write it back out to the SDCard
What does the preview have to do with anything? Every tutorial (including android's includes it), but I can't figure out for the life of me what the thing does...I could see if you wanted a camera viewport in your app, but I don't.
Now what I DID do was start the camera activity using the intent, then store the callback "data" into the surface, the problem with this, though, is it's EXTREMELY pixelated, the image previewed in the surface is of horrible quality, like it's a thumbnail. What gives? I used this code:
Code:
Bitmap thumbNail = (Bitmap)data.getExtras().get("data");
mImageViewer.setImageBitmap(thumbNail);
So yeah, sorry the questions are so sparsed out, just been confused as hell and am unfortunately on a truncated time table - nobody's been able to explain anything so far, just have what I have from playing with it..
TIA, sorry for the long post
Bump*
Anybody? Somebody's had to use the camera before in an app..
How do I set one of my own pix, located in the eMMC /media as a wallpaper WITHOUT having resize it?
I can set any pix by tap and hold on the main screen then choose Wallpaper and select the pix I want but it always asked to resize before let me save as wallpaper.
Doing so will shrink my pix. I don't want to resize it, how do I do it?
Note: even I pre-cropped my pix to 1024x600, it still wont let me choose the entire image as wallpaper.
Not entirely sure, but you might try moving your presized images into the same folder where the Cyanogenmod wallpapers exist and selecting from there. I know when I select those, it doesn't ask for resize.
Good strategy, krevo.
I'll try that but b4 that, where is the Cyanogenmod wallpaper folder?
Try QuickPic and please don't think I'm being insulting when I suggest you double check your horizontal and vertical dimensions. I have swapped them a couple times without thinking about it and then couldn't figure out why the pics looked so messed up.
+1 for QuickPic--Love It!
Running off eMMC w/o uSD, Gallery didn't work so QuickPic was my one of my choice and is my favorite (other choices were Large Image Viewer, ...)
Anyway, as I stated above, even 1024x600 pix, still forced me to crop. Expanding the crop box to maximum, of course, still not happy with it. I look for a way to just use the pix as wallpaper w/o modifying the image.

I looked and it turns out that it isn't a folder its an app.

I thought/hope krev said that he did put his pix in the folder.
anyway, I don't know why it's so complicate just to use our own image as wallpaper w/o doing resizing.
It's strange that you can't. I don't have any trouble. How many screens are you using? That might have something to do with it. This thread has some suggestions you might try.

If you can and I don't then I blame myself first, must do something wrong. Will try again and again.
Anyway, I always set up 3 screens (note: by default, it's 5)
In that thread I linked some people are saying that Wallpaper Set and Save made it work for them.
I just don't understand why we are all having different experiences with setting wallpapers. I guess there are so many possible combinations of ROM, launcher, resolution, apps, and who knows what all else. I seem to recall a big thread at MobileRead about this very thing.
Another thing you might try is searching the Nook Themes And Apps forum here for wallpaper threads. This is a common situation that has been solved several times but not always the same way.
