[Q] Change lockscreen background programmatically - Galaxy S III Q&A, Help & Troubleshooting

Hi,
It is more app development question, but as I mostly reader and don't post a lot - I have no access to dev forums yet.
I have my own wallpaper app (Awesome Nature Wallpapers) and noticed that it can't set wallpaper for lock screen when it runs on SGS3. When I test it on different phones (my old SGS1, GT7.7, Motorola Defy+, some Huawei phone and emulator) it is working fine - lock screen is transparent and wallpaper is visible, but not on SGS3.
Does anybody now how to change SGS3 lock screen background programmatically (I mean not from settings)?
Thanks in advance!

Need to use the stock gallery. QuickPic can do it as well but you still need to crop the photo using the Gallery's editor otherwise it won't work. Another option is to download a really old app called Wallpaper Set & Save. Works really well.

Sorry, I probably didn't explain properly - I'm not looking for another app to do it. I'm looking for a way to do it from my own app which I'm developing. Standard Android methods of changing wallpaper don't work for S3 lock screen background...

[Q] Live Wallpaper on lock screen

On my phone running 2.3 the lockscreen shows whatever wallpaper I normally have including live wallpapers. However, it looks like in 3.1 you need to choose a separate wallpaper for the lockscreen and it won't let me choose a live wallpaper. Does anyone know a work around for this?
I don't know it, but it would be nice to have!
+1 would like to know too!

Bah I was trying to figure this out myself!
Someone please figure this out
Even with 3.0 on the tab you got the live wallpaper on the lockscreen. The 3.1 update brought with it the (for lack of a better term) "dead wallpaper lockscreen".
All I can figure is that this must be their way of goading us into making custom roms...

Yes, while using the Desktop Dock in clock mode you get the currently selected Live Wallpaper. Can't find a way to get this on the lockscreen though. Perhaps 3.2???
My Xoom on 3.1 had live wall lockscreen so it can't be a 3.1 issue. While it's nice to have the option of separate walls, it would also be nice to have the option to have the same live wall across the entire device....you listening sammy?

Any update on this?
WidgetLocker doesnt look right on the tablet...
When I flashed the pda md5 in this thread (http://forum.xda-developers.com/showthread.php?t=1119492) it worked perfect. Then I flashed Bonsai and it went back to no live wallpaper...
Got to be an easier way?
Also running Bonsai. It's annoying as it seems like the 'dead' wallpaper which is setup in the default settings actually overwrites the live wallpaper being displayed under the lock screen. The live wallpaper is there, just covered up.
Example: using Multi Picture Live Wallpaper, set the lock screen wallpaper to some distinct image, and the desktop to another image. The lock screen wallpaper will default to whatever is selected in the tablet settings. When you unlock, you should see a flash of the selected lock screen 'live' wallpaper which is displayed 'under' the dead wallpaper...
I played with settings in Multi Picture, but it doesn't seem to be able to override this.

GO Launcher Ex Wallpaper Zoom

Hey everyone - having a slight problem with my all-time favourite wallpaper (which I brought along from my Symbian device) in combination with GO Launcher Ex.
Whenever I try to choose it as my homescreen wallpaper it gets zoomed in and very pixelated - TouchWiz doesn't have that problem.
Unfortunately Google & site search weren't able to provide a satisfactory solution ..so, anyone have an idea how to get it working?

Try to get that pic in 480 x 800 resolution, it will fit perfectly for portrait mode wallpaper.

Cheers mate, seems to have worked!
Blew the pic up to 480*852 first and then cropped 52 pixels from the top (only black anyways).
Resolution still seems to be fine enough.
Guess another possibility would have been to make a new all black 480*800 image and copy mine into the centre of that ..
Mmh. Will try that aswell.
*edit*
Crap. Just installed the newest version of GO Launcher and back to zoomed wallpapers we are - regardless of size. Only way to fix it is to switch back to TouchWiz and then back to GO Launcher again - which sucks.
!%#'"ยง!
What if you use Wallpaper Set and Save or Wallpaper Plus? They come out very sharp when I use apps like these.
I have noticed this bug as well. I can get it resolved by going back to the default launcher temporarily, set the wallpaper there, then relaunch Go Launcher, and it seems to be correct. It only happens to portait pics where there is no background scroll though.
Could it not be due to the wallpaper being in scan mode (as you go through the 7 screens the background image moves along)? Because in my HD2 (in SD Android) would select a square-ish area from the centre of the image I wanted as a wallpaper. When I changed it to the same image for all screens, then the selection of the image was in the same shape as the screen.

Are those Apps? Haven't heard of them before and might give it a shot - however there's probably also a certain increase in battery use associated with that method, something I'm not sure I'm prepared to accept.

Yup, exactly the same here. If only it weren't for the GO Launcher Calendar widget, I'd try another launcher or stick with stock TouchWiz ..

I have unticked that option, the background isn't scrolling.
Meh..
*edit*
The problem seems to be known but possibly not recognized as a problem by the GO Dev team:
After the research, it seems the wrong of Android system. Because the API we use to get wallpaper of system give us the zoom wallpaper.

Also, another possible solution seems to be https://market.android.com/details?id=org.tamanegi.wallpaper.multipicture - however, Live Wallpaper = more juice required.
Same here happened. I just switch to TW luncher and back to GO luncher
Actually, installing the latest update of the GO Calendar widget seems to have fixed the problem.
When I installed it the wallpaper first bugged out again but when re-setting it, it worked fine without switching to TouchWiz. Perhaps that'll work for someone else, too.

Had same problem, stopped using stock gallery to select wallpaper, and started using qpix to select wallpaper, and it works fine for me now. Seems problem for me was the stock gallery app I was using to select the wallpaper.
Currently having the same issue and neither TW or GoLauncher is playing nicely with me.

I am having a problem I am using GO Launcher Ex and my backgrounds appear to be zoomed in a little bit even though when I'm setting the wallpaper it is fully zoomed out with the orange box. It has only recently happened because it never did that before and it happens no matter what wallpaper I set.
Android 2.3.6 CheckROM GT-i9100
Anyone have any answers?
Thanks.

Just an update: I found that switching back to twlauncher fixed the problem with the wallpaper! Switched back to Go Launcher Ex and it stayed fixed. Weird.
In case that doesn't work
Hey I found that my background would not scroll if I swapped to the tw launcher and then back, and it seems that its the default wallpaper selector. I use wallpaper wizardii and choose the scroll option when setting wallpaper and it works great.

Is There A Way To Randomise Live Wallpaper?

Similar to screensaver managers you'd find on other OS's? My preference is for it to randomise upon startup, anyone got any ideas? Is there a way to do it via Tasker?
Please bare in mind that I'm asking how to randomise live wallpapers, not standard, thanks!
There's an app called Multipicture live wallpaper. Allows you to choose a folder or album and lets you set things up. All you do is double tap screen if you want to change on the fly or let iit randomize on its own. This also puts a different picture on every screen. THE drawback is this app isn't ICS supported yet. It doesn't work on stock launcher. BuT if you get ADW launcher it works on that for some reason.
That's not for live wallpaper though is it?

Appreciate your guys time, but you're missing the point of the thread
I've used an app called Zedge on my Incredible2 and my Nook Color running Cyanogenmod 7 to download and set wallpapers and it has an option to randomize which wallpaper is displayed and change it automatically at an interval you set.
I haven't tried it on my TFP or ICS yet but I would recommend giving it a shot.

[Q] Optimus G Lockscreen Live Wallpaper

hello. if this has been asked before, please point me to the thread and lock this one. i am wondering if it is possible to make your lock screen wallpaper a live wall paper like you can your home screen? i know with the gs3 you could do it from settings, but in my lgog the lock screen settings doesnt have the option to select live wallpapers for it. it only lets me use gallery pics or wallpaper pics, not live wallpapers. so does anyone know of a trick to get it to enable live wallpapers on the lock screen? thank you for your time.
I just got done scouring the internet for an app or mod to do this but I came up empty. I think there was some weird limitation because there was plenty of interest for something like this and a few bootleg ideas.
The best of those is clear lockscreens which let you see a live wallpaper if one is set as your normal background, but that's the best you can do at least for now. Just search for clear or transparent lockscreens to try it.

Well you could delete(make sure to copy it somewhere first) lockscreen3.apk and you will have the ability but you lose the shortcuts and the lock screen just looks like this and the camera button doesn't even work
Sent from my LG-E970 using xda premium
And I have tried the clear .png and it doesn't work. The lockscreen app has a white background behind it that I don't believe is an image, so I don't know how you would take it out.

[Q] Wallpaper keeps croping, used apps already

Hey guys,
Was wondering if any of you know how i can get a full screen wallpaper for my Z2, since i tried the app Wizard (weird name after) and now im using Wallpaper setter.
Wizard did not work and wallpaper setter, at it's best cuts the notification bar and half the buttons of the dock.
Tried googling 1080x1776 wallpapers instead of 1080x1920 too, to no better result.
Wanted to change, since the stock wallpapers make for a crappy homescreen, since it is already a washedout screen (i come from a note 3, so probably it's just my opinion).
P.S. Was wondering if you can use any method to not crop the images on lockscreen too
Thank you
I use this to crop them perfectly. Even gallery images, just use this to set wallpaper.

i use image2wallpaper or image2livewallpaper
You can try Background HD Wallpapers app from pkaystore.. Its one of the perfect one available. Screenshots attached.
