如何制作 Android 动态壁纸动画
我们正在尝试为Android手机开发动态壁纸，但是当涉及到动画部分和APK的大小时，我们有点卡住了。
我们尝试了 Sprite 动画和 PNG 逐帧动画，由于 PNG 图像或 Sprite 条纹的大小，两者都会消耗手机中大量空间（不到 2 秒的动画超过 10MB）。
但我在应用市场上看到过一些动态壁纸，它们有很棒的动画，但 APK 大小不到 1MB。有办法实现这一点吗？如果是这样，我们将不胜感激任何人的帮助。
提前致谢！
We are trying to develop a live wallpaper for Android phones, but when it comes to the animation part and the size of the APK we are a bit stuck.
We tried Sprite animation and PNG frame by frame animation, both consumes large amounts of space (over 10MB for less than 2sec animation) in the phone due to the size of PNG images or Sprite stripes.
But I have seen some live wallpapers in the App Market which has amazing animations but the APK size is less than 1MB. Is there a way to achieve this? if so any assistance from anyone would be much appreciated.
Thanks in advance!

作为第一种方法，我建议您尝试 andengine 平台及其动态壁纸扩展 (http://www.andengine.org/)。由于平台开发人员已经处理了很多类似的问题，我认为您没有理由重新启动轮子。 AndEngine平台具有许多内存和速度优化功能，特别是在GLES2版本上，并且它是免费和开源的。

Since the platform developers have dealt with lots of similiar issues, I think there is no reason for you to reivent the wheel. AndEngine platform has many memory and speed optimization features, specially on the GLES2 release, and it is free and opensource.
