![]() ![]() Inside this package, create a new class called GLWallpaperService.Ĭreating a new wallpaper service subclassĪt the beginning of our new class, GLWallpaperService, extend WallpaperService: public abstract class GLWallpaperService extends WallpaperService 4.Start off by creating a new package to contain the live wallpaper classes.We’ll be working with the Android OpenGL tutorials as a base, which can be downloaded from GitHub. This engine handles the actual lifecycle events of the live wallpaper. Each service is really just a wrapper around an engine, which is subclassed from WallpaperService.Engine. Creating the wallpaper serviceĪndroid Live Wallpapers are built off of WallpaperService, so the first thing we’ll do is create a new class called GLWallpaperService. I found these through this stack overflow question: įull credits to Ben Gruver for showing us one way that it could be done in this article, we’ll work with our own adaptation of GLSurfaceView, with an emphasis on using it for OpenGL ES 2.0. The first evidence I found that it was possible to use GLSurfaceView in a live wallpaper was from these files, by Ben Gruver: Approach One: Using GLSurfaceView inside a live wallpaper Let’s begin with the first approach: using GLSurfaceView. We’ll also look at combining the two approaches and allowing the user to select between the two. Approach 2: Using a custom live wallpaper based on the internals of GLSurfaceView.Approach 1: Using GLSurfaceView inside a live wallpaper.Here are the two main approaches we’re going to look at: Later, we’ll see how we can use Robert Green’s work for rendering with OpenGL ES 2.0. To start off, we’ll first look at adapting the existing GLSurfaceView for use within a live wallpaper. Since this is a research article, we’ll take a look at both options two and three. One caveat that I do have is that we need to duplicate a lot of the code and functionality inside GLSurfaceView, and we won’t be able to benefit from updates or variations between different versions of Android. Robert Green has generously written up a re-implementation based on GLSurfaceView, and many have successfully based their wallpapers off of this code, so this might be one way to go. Re-implement the features of GLSurfaceView.This lets us reuse a lot of code, but since this class was written to be used inside of an activity as a view, it might behave a little weirdly if we try to use it in a live wallpaper. ![]() Use GLSurfaceView, and adapt it to a live wallpaper.This might be a preferred option for some, but I won’t be exploring this in any more detail. If you want to do OpenGL in a live wallpaper, it seems that there are a few alternatives: Allowing the user to switch between the two. ![]()
