Android Renderscript 实例强制关闭

Question

我找到了这个 link我想试试轮播的例子。我将所有类和 rs 文件(轮播示例中的所有内容)复制到我自己的项目中，并尝试在实际设备(摩托罗拉 xoom)上构建它。但我一直在强制关闭。 logcat 中的错误是:

11-01 11:37:23.490: E/RenderScript(927): 0x17c718, couldn't find an EGLConfig matching

我不知道这意味着什么以及我应该如何解决这个问题。有没有人有这种问题？

正如帖子中所说，我在实际设备上运行它，而不是模拟器。问题是这个 link , 但他们在 android sdk tools revision 15 中解决了这个问题。所以下载新版本的 sdk tools，应该没问题。
