This depends on the screen technology. For instance, (it was said that) Android 2.3 Gingerbread has dark theme since Google's latest flagship device Nexus S uses (Super) AMOLED display which consumes less energy when displaying dark color since AMOLED produces its own light and darker color emits less photons. Contrasts with LCD display which uses a ...

Here are the correct wallpaper dimensions for the phones cited in Leimi's answer: 480x320 for devices like the HTC Wildfire 640x480 for devices like the HTC Hero or Legend 960x800 for devices like the Nexus One 960x854 for devices like the Motorola Droid If you device isn't listed there is an easy way to figure out the dimensions of the wallpaper ...

Hey, I just ran a load of test to figure this out. They are vaguely scientific tests! I figured out that I was saving 20% battery by switching to dark wallpaper and dark themed apps. Have a look through my write up, you should be able to work out the saving on your phone: http://blog.stevemould.com/phone-battery-save-black-wallpaper/

The wallpaper was in data/data/com.android.settings/files/ on previous versions of Android. However it appears that it was moved as part of the multi-user preparations. The current location is data/system/users/0/ The file is conveniently called wallpaper and it is a png file.

Android OS versions 3.x and above (Honeycomb, Ice Cream Sandwich) actually have a setting that allows you to specify "Owner info" text that will show up when the device is locked. There are also many 3rd-party locks-creen replacement apps that allow for much greater configuration flexibility than the stock one, including the ability to specify any text on ...

I'm not sure if it's the same on older systems, but on ICS it appears to save directly to /data/data/com.android.settings/files/wallpaper. I set mine from the browser, pulled that file, then changed it to a .png extension and viola - it was the image I had set. It also appears that this file simply gets overwritten when you change your wallpaper, so I don't ...

Different wallpapers drain the battery differently. It really depends on how many different factors the wallpaper is paying attention to. Is it just being pretty or is it altering itself based on every movement of your phone? The best way to find out is to simply test it yourself. Spend one charge of your phone running a live wallpaper. When you get near ...

What you're referring to are called HTC Scenes (Hero Scenes link). Off the top of my head I don't know of anything like that and only HTC devices have the HTC Scenes. I just did a quick search of the market and didn't come up with anything so my initial guess is: No, there is nothing like that currently. You would either need a Sense-based custom ROM (not ...

Someone over at the XDA Forums already discovered how to do that. See link to the thread below. I strongly advise to follow this guide only if you know your way around the procedures mentioned (repacking & zipaligning an APK file, file system operations with root permissions) and wouldn't mind jumping through several hoops to recover your device if the ...

I was annoyed by the exact same problem, so I have programmed an app that automatically saves your wallpapers and your live wallpapers too. It makes it easy to revert to a previous wallpaper. It is called Wallpaper Saver and it's free in the Play Store. (It does not require root access.)

If all you want is static text that doesn't change in any way, then by far the easiest way is to open your wallpaper image in an imaging editing program either on a PC (something as simple as Windows Paint would do) or on the phone (search the Android Market for something like "image editor" or "photo editor" and you should find lots of apps that can do this ...

It depends on your screen resolution : 480*320 for devices like the HTC Wildfire (QVGA) 800*600 for devices like the HTC Hero or Legend (HVGA) 960*800 for devices like the Nexus One (WVGA800) 950*856 for devices like the Motorola Droid (WVGA854) edit : in fact some of this dimensions work but are not the correct ones (they fit because of the same aspect ...

You're right I just played with trying to set a Dropbox image as my wallpaper, and can't believe that there isn't an easier way. Part of the problem seems to be that if you Open a dropbox image, it isn't sent to the Gallery or the system default image viewer (which would let you do things like set as wallpaper) but Dropbox uses its own (HTML?) viewer. There ...

OK, what I ended up doing was using the ASTRO file manager app to access /system/customize/resource on my phone, which seems to have the wallpaper graphics (amongs a load of other stuff). I copied the wallpaper I wanted to customize to an easy-to-reach place on the SD card (Edit | Copy, then Paste, in ASTRO), and copied it to my PC. Customized the ...

Pretty sure this was present in Eclair (but it's possible I'm mis-remembering and this was a new feature in Froyo) but when you select a picture in the gallery, at the cropping stage it should give you a choice of screen resolution/aspect ratios to use. One of them should be the resolution of your screen, the other one is for the side-ways scrolling ...

I have Nexus 7 with stock Jelly Bean 4.2. Wallpapers are stored in /system/app/Launcher2.apk/res/drawable-sw600dp-nodpi as wallpaper_01.jpg to wallpaper_14.jpg but your picture is not here. I checked wallpapers in version 4.1.1 online here: https://bitbucket.org/neuralassembly/jcrom_packages_apps_launcher2/src/bd231599ae9f/res/drawable-sw600dp-nodpi And ...

Most Android phones come with an app called "Downloads" where you can find any file you may have downloaded from the internet. From there, you should be able to view the picture and set it as your background through the Menu key settings. Another way might be to look in your Gallery application (or any photo viewer). Most of these will display the Downloads ...

AFAIK the default Android launcher does NOT allow you to do this. However, there are some launchers available on Play Store which let you do this. Regina 3D Launcher is one of them. The other option I see is what you are already doing, using a live wallpaper like MultiPicture Live Wallpaper. (I have mentioned some popular apps to do this, there are ...

I have just developed an app that can save your current wallpaper to SD, share it, ect. Furthermore it automatically saves a copy of each wallpaper you set, so you will get a history of all the wallpapers you have been using. My app is called Wallpaper Saver, can be downloaded from Google Play and is Free! Download it here: ...

some portion from all the four sides of the cropped image is not displayed. At least it seems so -- but that's perfectly normal ("works as designed"). Android does not think of it as a background image solely for the "recent homescreen", but rather for your "collection of homescreen pages". If you swipe through your homescreens left-to-right (or in the ...

Although I am on another device with another android version (HTC Desire HD / ROM: JellyTime R9 (Android 4.2.2)) I think the problem may be the same. In gallery I can only set the images as background. But I can set a different lock screen background image in system settings. I think this options depending on used Launcher/Lockscreen and are also valid in ...

It looks like what you're describing is actually the proper behavior, though it's not particularly obvious why that's the case. Android, by default, scrolls your wallpaper to the left and right when you swipe around your home screen. This means that there's a sort of "virtual" desktop that represents the collection of your home screen pages, and it is ...

I emailed HTC and this was there response in case anyone is interested. "I understand you have a question about Live Wallpapers for your Android device. I would be more than happy to assist you with this device feature inquiry. You mention that you would like to know whether a developer would have access to the area where you choose the wallpaper or ...

I have a HTC One X too, and I hadn't noticed yet that wallpaper scrolling is not working anymore. After some searching in the settings, I haven't found the solution to your problem. So I think that I have to conclude that there is no option to restore this functionality. Reverting back to previouse Sense versions is not an option as far as I know. Rooting ...

I have found the solution. The original image size was huge (about 2600 pixels wide). So I used Photoshop and transformed this image to 960 x 480. Now the image looks the same way when set as lock screen or home screen wallpaper like below:

I have been trying to retrieve the wallpaper as well but found it too difficult. So to solve this I have create the app "Wallpaper Saver". It automatically saves your wallpapers and makes it easy to restore an old wallpaper again. It also supports live wallpapers. It is free to use. You can download it from Play: ...

The screen size is 600 x 1024 pixels in portrait mode. That's not the same as the wallpaper size, since the wallpaper is bigger than a single screen (try scrolling your homescreens left and right to see this). Usually you need to double the width, and from what I can see online this seems to be the case for the Tab as well. So use 1200 x 1024.

You could try an app like WallSwitch, which can be set to change your wallpaper every time you unlock the device or on a timer. I don't know that there's a way to tell it to pull from "the gallery" in general, but you can just specify that you want to pull from the folders your gallery images are in (works out effectively the same).

When I select an image from Dropbox, it opens to be viewed. Then if I press and hold the image, I'm given the option to Open, Download, Share or Delete the image. If I choose Open, the image opens in a view similar to the Gallery in which I can press menu, then Set as and finally, Wallpaper. This still requires several steps but you never have to actually ...
