As of the latest Android API 24 it is possible to update the Lockscreen wallpaper by using the WallpaperManager and providing the FLAG_LOCK flag.

wallpaperManager.setBitmap(bitmap, null, true, WallpaperManager.FLAG_LOCK)

it's work me but not in Marshmallow phone – Bipin Bharti Mar 31 '17 at 12:31
@RobbyPatel as mentioned this was added in API 24 (so it is not available in android versions prior to API 24) and there will never come support – mikepenz Apr 03 '17 at 15:12
but some Samsung phone has available Lock Screen Wallpaper how it works? – Bipin Bharti Apr 04 '17 at 05:29
As samsung is modifying the SystemUI they can do whatever they want. But they do not offer an API via the android SDK to allow you to change that – mikepenz Apr 04 '17 at 15:10
my device version is 24, it is not working – Amarjit Mar 18 '18 at 05:50
Which device do you use @theLazyFinder Some OEMs do not allow these APIs and you are sadly out of luck with these devices – mikepenz Mar 19 '18 at 17:15
I am using Redmi note 4 – Amarjit Mar 19 '18 at 17:16
This Code is not working on Redmi Note 5 Pro, API 27. Any one has any idea why it is not working or any way to check if the device is supported apart from API level? – Avineet Gupta Oct 22 '18 at 08:54
@AvineetGupta This is a limitation of MIUI. Please see https://in.c.mi.com/thread-1252992-1-0.html – Shrey Garg May 27 '19 at 08:57
