I'm using a Wallpaper Manager for setting an image as Home screen. It works fine for Lock Screen, but not for Home screen. This image that I want to set as Home screen is as wide and long as the screen, so it gets blurred when stretched across multiple screens. I'd like for this image to be repeated on each screen, not stretched across all. Is there any solution? I'm open to any idea, even if it doesn't include wallpaper manager.
I get it too, bro. But this package have a function called setWallpaperFromFileWithCrop
so you can let user crop image to set wallpaper as you want.
I have large landscape image, I want to move that image smoothly across the screen without loosing aspect ratio. If you cant understand my question, please have a look at Android Newsstand app in that the cover image on top of the screen moves smoothly across the screen back and forth. how can i achieve that. please have a look at the image attached. The background image needs to move smoothly to the right when it reaches end it should move back to left.. Where should i start ?. Thanks in advance.
Update: Solution
PanningView is a library which implements the animated background in the now playing screen of the Play Music app.
Have a look at this library https://github.com/flavioarfaria/KenBurnsView
It is exactly what you are asking i hope :-)
Also do give a look at my this, which is modified ken burns view

So, I have an application that uses a canvas and animated a moving block. What I would ultimately like to do is have the camera running capturing the user's face without showing the camera screen on the app or have a box at the bottom right of my screen that showing what the camera sees.
Is it possible to have a mini screen at the bottom right of my app that is displaying the camera or does the camera have to take the full screen?
Or if it is possible just to quickly snap a picture and display a bitmap without losing my application, that would be fine also.
Any help would be great!
Thanks.

It is possible, See the 1st Screenshot here. Theirs is in top left instead of bottom right, but it should work just the same. In this Qik application the full screen shows the other person you are talking with, and the small box shows the live view from your camera.
I wouldn't know how they did that, but I imagine if you follow along with Building a Camera App in the docs it would get you most the way there. You just need to adjust the size of the preview canvas, and figure out how to use the front camera instead of back.
I've been facing a problem. How do I set a wallpaper in Android, without stretching it across 5 home screens. To be clear, I have a resource images with resolution 320x480px and when I set it as wallpaper in Android, it gets stretched across 5 screens, but I want it to show up only in 1 screen (or the same image in all screens), got it?
I'm not interested in using a livewallpaper.
Only way to have an app do that is using a live wallpaper.
There are two types of wallpaper, static and live. The scrolling of a static background is controlled by the launcher app. This is why LauncherPro and ADW can control the scrolling. When the user chooses a live wallpaper, the launcher simply displays whatever the LWP wants to render, so the LWP controls the scrolling, if any. This is how MultiPicture LWP solves the problem.
So your only options are to implement a custom launcher (which I doubt you want to do for such minor functionality) or implement a live wallpaper.
And BTW, setWallpaperOffsetSteps is an internal method called by the launcher on a live wallpaper, so the LWP knows where it's supposed to be drawing. You can't call it directly, but you can listen to onOffsetsChanged within your LWP to facilitate your own scrolling implementation.
Tap and hold your screen when you get popup "add to home screen"
select "wallpapers"
select "home screen wallpaper"
when you've selected a picture from gallery or explorer you get a screen where you can crop your Image to fit home screen.
On the bottom you can select 2 type of crops.
A big crop for setting it accros 5 screens and a small crop to use the same BG on all 5 screens.
see screenshot:
select the latter, crop your picture and save.
Not possible. May be there are any private libraries for it.
Apparently it's not native Android functionality. You can, however, get apps that do it. "Launcher Pro" and "ADW EX Launcher" can both disable scrolling but you may need to create a landscape rectangular image with empty borders at the right size.
Alternatively, the app "MultiPicture Live Wallpaper" may do what you need. A reviewer wrote: "Lets me use a picture sized the same as my phone's screen as the background on all pages of the launcher. Not sure why that isn't part of Android."
EDIT: have a look at tdtje's post before you try these. If that works, then awesome. I'm not sure which version of Android that became available in, as I'm using 2.1 without that feature.
FURTHER EDIT: In the comments below, Martyn gives us a first hand opinion!
I went to Settings and clicked on home screen. Then went to wallpaper. I selected my picture and cropped using the gallary app. This had a setting on the top to either stretch or not. I'm running Android 4.4.
I want to programmatically set a wallpaper to be an exact fit of the current screen.
Android fits the image to scroll as you change windows by defalt and so you never see the whole image on any one screen.
Applications like Wallpaper Wizardrii perform the function of setting the image to a single screen for the user, but I have never seen an answer on any forum that suggests how this is done.
Can any Android guru out there help - this problem has been doing my head in for nearly a week now!
You need to write a Live Wallpaper so you can render your image to the screen exactly how you want. If you just set a static image, the launcher app (or anything else showing the wallpaper) will be free to adjust it and resize and scroll. By writing a live wallpaper, you get to receive the requests from launcher about what it wants to happen to the wallpaper, and follow or ignore them as you want.
Also conceptually "make the wallpaper an exact fit for the current screen" is not even possible, because there is only one wallpaper, but two orientations (landscape and portrait) it can be shown in. That one wallpaper just fundamentally can't exactly fit both orientations.
