The Android wallpaper system is a bad design. Bad.
I'd love to toss out 10 or 20 wallpapers for Android devices, but there's a major challenge: size.
Of course there are different screen sizes. PC's have that issue too, it's nothing new. That's not the real problem.
The problem is that even if you know that your device (say a 1024x600 Android tablet) has a certain resolution screen, it doesn't use that size wallpaper.
That's right folks, the wallpaper does NOT match the screen size. It's assumed to be larger. Ok, that doesn't sound that bad. Oh, and it gets displayed and clipped differently depending on landscape or portrait mode, and even depending on the device.
For instance, typically you want something 1.5 times wider than your screen to handle the multiple home screens. If I use a tablet in landscape mode, that means I want an image that's 1536 x 600, right? No, you're going to need 1536 x 1024 because when you turn the device it's going to use the 1024 wallpaper height. That means for 90% of your viewing pleasure, the bottom 60% of the wallpaper will be cut off because you're in landscape. When you flip to portrait, you'll get to see that bit.
