Android set wallpaper programmatically

Recently, iPhone users have been bragging that they can set Live Photos as their lock screen wallpaper. While this is a great way to spice up a boring lock screen, Android users shouldn't feel left out in the cold.

However, the app's myriad of options can feel overwhelming at times — you might be unsure of how to do exactly what you want to do. Well, that's what we're here for. If you're anything like me, you've probably seen thousands of GIFs, but you likely haven't downloaded a single one.

Luckily, it's simple enough. Long-press on the GIF you want to download, then tap "Download image. Tap on "Install" to download and install it, then open it up.

When you first open it up, the app will ask you read the privacy policy. You can either tap the link to read the full policy, or you can do like I did: Lie, say you read it, and tap "Yes.

Tap the picture icon in the top-left of your screen. Your pictures will appear here. If you recently downloaded the GIF you meant to set, then it should appear towards the top of this list.

You can resize it with the pinch-to-zoom gesture. You can also utilize the four arrows in the top-left portion of the screen. The arrow facing upwards will immediately snap your GIF to the top of your screen.

The same goes for the left, right, and downward-facing arrow. The plus sign in the center will center your GIF. If your GIF doesn't fill out the entire frame, or if you simply chose not to resize it, you'll see borders around the image when you set it as your background.

There are two ways to change the color of these borders. One, you can tap the dropper icon in the top of the screen. Next, tap on any spot in the GIF and it'll match that color perfectly.

You can also manually change the background color by first going to the hamburger menu in the top-right corner. You'll see three sliders for red, green, and blue. Adjust these sliders yourself, and the sliders will change color to reflect the background color you'll set.

Confirm the color by tapping the dropper icon in the top-right. Go back to the edit screen by tapping on the hamburger menu in the top-right. By tapping on the hamburger menu in the top-right corner, you can enable a setting that will allow you to see how your GIF will look in landscape mode.

How to Set Wallpaper in Android Programmatically?

You can either set a regular image as a wallpaper or you can choose from live wallpapers a moving image. But the thing is, there are not many good live wallpapers and even the good ones get pretty boring pretty quickly. Guess what, you can also set your own videos as wallpapers. In fact, the concept of setting videos as wallpapers is nothing new. It has been available on desktop computers for ages.

There are many apps that let you set videos as wallpapers but in this guide, I will show how to do it using two different apps. Each app has its own strengths and weaknesses. I want you to know a couple of things. First, when using video wallpapers your device battery will drain faster.

Sometimes, even faster than when you are using a regular live wallpaper. The second thing is optional but it can be helpful if you can make sure that the videos you are trying to set as wallpapers are in MP4 or 3GP format. This ensures maximum compatibility with all devices and video wallpaper apps. If you have cute GIF, then you want to set as your Android wallpaper, then you need to first convert it into in a video. For sake of this article, I used this website and it worked fine.

VideoWall is a free and ad-supported app that lets you set any video of your choice as a wallpaper with just a few taps.

How to Set Video or GIF as Wallpaper on Your Android

Using the free version you can set any video as your wallpaper while trimming the said video as and when needed. This trimming feature is particularly useful when you have a long video and only want to set a part of the said video. To start off, download and install VideoWall from the Play Store.

After installing, launch the app from the menu. The above action will show you a list all the video files on your device. Select the video file you would like to set as a wallpaper. If you are not sure what video you want to set your wallpaper, go to YouTube.

You would probably find it there. When you select the video file, you will be taken to the editing screen. Here, you can drag the starting and end sliders to trim the video as needed. For instance, I trimmed the video so that it starts playing at the four-second mark and ends at the thirteen-second mark. Like I said, before you can make the app play audio in the background you must unlock the feature with an in-app purchase.

While VideoWall restricts you from playing audio and scaling or cropping the video to fit your screen, Video Live Wallpaper does it for free. However, unlike the VideoWall app, the drawback of Video Live Wallpaper is that it has no capability to trim the video as and when needed. That being said, you can easily trim your video using any free online coverter or if you are using Windows 10, you can use the default Photos or Movies app.

Read: Video editing apps for Android. Other than that, using Video Live Wallpaper app is pretty simple and straightforward to use. Moreover, unlike VideoWall app, this app stores all the videos that you set as a wallpaper so that you can easily switch between them when needed. Once installed, launch the app from the menu.
