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 voil - it was the image I had set.
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, by Appdictive, and it's free in the Play Store. (It does not require root access.)
The location of the stock wallpapers is in an apk file that you should find on your device at /system/framework/framework-res.apk. Pull that file to your computer and then browse its internals. A search for a file with wallpaper in its name should prove fruitful.
Copy the images with high size (maybe more than 80 KB since they got a quality) and paste them into a folder that is not in a root directory. (Just copy it to your "Downloads" folder or to your SD card)
Depending on your device manufacturer and the Android launcher that you are using, it may not be possible for you to set a live wallpaper on your lock screen or to only set the same wallpaper as on your home screen.
When previewing a live wallpaper in Wallpaper Engine on your phone, long-press a few seconds on the check-mark symbol in the upper right corner. This brings up the live wallpaper screen of your phone. Depending on your manufacturer, you should now see the option to set the wallpaper on your lock-screen - if this option does not appear, your phone does not support live wallpapers on the lock-screen. The following phone manufacturers are known to not allow live wallpapers on the lock-screen on all or some of their devices:
If you wish to stop using a Wallpaper Engine wallpaper, you can simply assign a new wallpaper in your Android settings. Wallpaper Engine is just another wallpaper to Android and wallpapers cannot unset themselves.
If you are using Wallpaper Engine as a wallpaper but the wallpaper disappears without any error messages after a few hours, days or weeks, it is likely being falsely terminated by your phone's power saving functionality. Under normal circumstances, Android should never terminate live wallpapers for power saving purposes but some users have reported this happening to them. This depends largely on your device manufacturer, if Wallpaper Engine disappears regularly, disable power optimization for Wallpaper Engine in your Android settings. This differs depending on your Android version and device, if you are unsure, search the web for ways to disable power optimization for apps on your exact mobile device name.
Samsung has lots of things called partners. For Themes there are two types of partners. One is for all of Samsung and it has to do with merchandising and special access, etc. and you do not need to be that type of Samsung Partner.
However Theme designing (and that includes Wallpapers, icons and AOD) does require you to be approved as a Theme partner. You can not just upload wallpapers to the seller store like Android wallpapers. Samsung has a closed ecosystem for designers for themes and watch faces.
Checkout Unity3D and the Unity2Eclipse plugin, it's the easiest way I've found. Be warned, it's still beta and you have to use Unity 3.4 to get it to work. I see a lot of Unity crashes in my error reports and my retention rate is pitiful
From analyzing the screenshot you've provided, it seems like a pretty simple scene, with some post-effects added on top of the final image. Unity engine makes it easy to do stuff like that, with its visual editor, good asset import pipeline and post-processing chains. There are others engines that you could use to achieve similar visual quality (Rajawali is a particular good example), but it'd be a much more tedious task.
The negative side of using Unity is that it is somewhat heavy - it's expected to have an APK of around 9 MB in size for an empty scene. This doesn't really matters if you have a resource-heavy live wallpaper, though.
I've recently released uLiveWallpaper - a Unity asset that makes it possible to create live wallpapers for Android using Unity 5. It is well-tested and reliable, creates projects for Android Studio, complete with placeholder code to get you started.
There is a lot of advice floating on trying to hammer wallpaper into tablet with various apps from market, but really it works great to use high resolution image and crop it to work without rescaling.
When you want to set image as wallpaper, instead of going with it or asking how do you want it to fit - Android gives you confusing cross-shaped crop area to apply. Pretty much anything I have tried to feed it at first ended up horribly blurry and cut down.
There are too many smart phones and sizes, I have to create a lock screen for a client but dont know what size I should be designing, is there a standard size that applies to all? instead of creating separate sizes for different phones. Since wallpaper can be adjusted, wouldn't one large size fit all?
Another answer is to design this in a vector app (Illustrator, Affinity Designer, Inkscape) so that it's resolution independent, and then set up correct batch export parameters for all the most common resolutions for .pngs, and also export out a clean svg.
I prefer the iPhone 8 Plus screen which has the dimensions of 414 x 736 pixels. Keep in mind by designing for the largest screen size, you'll inevitably be conceding some of the edges of the design on devices where down-scaling isn't occurring at an exact ratio. Not a "deal breaker" in my opinion but worth noting to a client.
Screen widths (in portrait view) can range anywhere from 320px to 414px, and screen heights range from 568px to 812px. Averaging these out gets you roughly 367 x 690px. These aren't exact dimensions for any phone on the market, but they are close enough to the standard Android size (360 x 640px), the Galaxy S8 (360 x 740px), and the Pixel 2XL (360 x 720px) to justify designing to those screen sizes. I give the edge to the Galaxy S8 in this instance since Samsung currently has the edge in smartphone market share at the moment.
As mentioned in the previous section, Samsung is the preferential smartphone in the consumer market currently holding about 23% of the market share. What makes this a less reliable option for basis of design is iPhone holding just over 15% and the historical power struggle of Samsung vs. iPhone. In such a volatile market, it wouldn't be wise to base design solely on this data point alone.
While you can easily rely on one of these methods, taking all available information into account before crafting a design is the best practice. Before you sketch anything, or open the computer, figure out as much as you can. Solving the problem (in this case, which screen size will best exhibit the design vs. which screen size will best represent a universal experience) first requires the designer to gather information. The more information, the easier the puzzle becomes and the easier it will be to talk to your client about your solution.
I woke up this morning to see my wallpaper and lockscreen were a picture of weird shapes with numbers in them. I saw I needed a phone update so I did that and changed photo back to what I had but it then changed to another random pic half hour later.
I was told to soft reset which I did and once again changed to my photo. An hour later it again changed to something really random, would someone please help. I'm cautious with everything , haven't done anything strange and have a very good virus protection .
Hi @Mrinternational, do you have 'Wallpaper services' enabled on your phone? You can check this by heading to Settings > Wallpaper and style > Browse my wallpapers > Wallpaper services > Set this to 'None' to disable it.
@LinRGreenwood: Are the wallpapers that appear taken from the Gallery, or are they random? If they are Gallery images, please try heading to Settings > Wallpaper and style > Change wallpapers > Gallery, and check the 'Selected items' section at the top to see if multiple images have been selected. If they have, tap on the thumbnail of any images you'd like to exclude, leaving your preferred choices in place. Alternatively, if the 'Selected items' section is blank, choose a photo to create a wallpaper, and check to see if this resolves your issue.
Random, pics i have never seen before or have not taken. these are a different picture each morning and it is a picture of a desert or ocean view or something else. I happens at night when my phone is on the charger while i sleep.
In my case I noticed it will do so at times but for me it happens because for example il set a video wallpaper thru a 3rd party app (zedge)(awesome selection not just wallpaper) but the previous one will be selected directly through the phones wallpaper manager. And for some reason it will decide to stop the zedge video wallpaper and go back to either default or the one i selected just not thru zedge
Called with the current insets that are in effect for the wallpaper. This gives you the part of the overall wallpaper surface that will generally be visible to the user (ignoring position offsets applied to it).
Changing the wallpaper is one of the easiest ways to keep your Android device looking fresh. If you want to take things to the next level, you can set the wallpaper to change automatically throughout the day. We'll show you how to set it up.
There are a couple of ways you can approach this. First, you can use a live wallpaper app that automatically changes to match the time of day. The other method involves a bit more setup, but it also allows you to use specific images. We'll cover both below.
The apps we're using in this guide are live wallpapers, meaning they dynamically change, rather than just displaying a static image. Before we look at the apps, though, let's learn how to set a live wallpaper.
