[android-developers] Re: OpenGL ES 2.0 for Live Wallpapers
ok i found errors in your code:
- you need to find the sTexture location in the shader program
- texture non square doesn't work. I force 512*512 for the test
For the second point, i have no idea why it works in an activity and
not in
the LWP.

The GLWallpaperService doesn't work either. We have a black screen or
green screen. That's strange because many LWP with OpenGL ES 1.x as
Aquarium are working. Using baksmali, we can see that they use

[android-developers] Re: OpenGL ES 2.0 for Live Wallpapers
My Galaxy Tab ROM is XWJJ4. The problem with OpenGL ES 2.0 Livewallpaper seems related to FBO. If i use them, it crashes on many phones. Only my N1 (CM7 alpha version 47) works.

[android-developers] Re: OpenGL ES 2.0 for Live Wallpapers
I tried your livewallpaper with the official (carier Orange) ROM on my GalaxyTab and it doesn't work either. The problem is clearly the FBO. When you use a FBO in a LiveWallPaper, on your main surface you will have a Black Screen. The problem doesn't really crash your phone but you have no painting. If i remove your FBO and draw lines without blur, your LWP is working on all my devices (N1, A101, Galaxy S, Galaxy Tab, Milestone ...) otherwise only N1. The same code in an Activity has no problem. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: OpenGL ES 2.0 for Live Wallpapers
Having used GLWallpaperService for several live wallpapers (and if you're reading this, Robert, my thanks) - albeit no OGLES2.0 - my advice would be to just extend it for the methods you need. It's a very straightforward port from GLSurfaceView; the methods line up very nicely, so if OGLES2.0 adds one that you need, just try implementing it with the same footprint, and see how it goes.
