This is our first attempt on the Android Market and we are very excited! We've put in allot of effort to make this happen!
The wallpaper supports multiple themes and customization options along with the standard scrolling behavior that you would expect from an Android wallpaper. A dynamic ambiance system allows for seamless day and night transitions independent of the selected theme.
The wallpaper is written entirely in Java using the Android SDK. For rendering we are using OpenGL ES 1.0.
Initially we planned to use the android2d library to do our renderings but it turned out that the performance that we were getting was not adequate. Our application was too heavy on pixel processing (alpha blending in particular) and we decided to go for OpenGL hardware acceleration. It ended up being more work to implement but we find it being a good choice as it made our application run very smoothly on a variety of devices and reduced the pressure our app was putting on the battery.
A particular challenge in using OpenGL was supporting the large scroll-able backgrounds because in our case the bitmaps could stretch to a good 10k pixels in width. We found out that the maximum supported texture resolution on different devices was far from standard. Some devices supporting only up to 512x512 textures or heaving very poor performance with larger ones.
Our engine automatically partitions the large backgrounds into smaller chunks based on the optimal configuration for the device it's running on (support for NPOT, maximum texture dimensions, support for compressed texture formats, etc.) while taking into consideration memory efficiency. This allowed us to have very high-resolution seamless backgrounds even on low-end devices.
