Android Renderscript示例强制关闭

Question

我发现这个link，我想试试旋转木马示例。我把所有的类和rs文件（所有来自轮播示例的文件）复制到我自己的项目中，然后尝试在实际设备上构建它（Motorola xoom）。但是我不断收到武力。在logcat中的错误是：

我不知道这是什么意思，我应该如何解决这个问题。有没有人有这种问题？

Answer 1

正如在文章中所说，我在实际设备上运行它，而不是仿真器。问题是这是link，但他们删除了android sdk tools revision 15中的问题。因此请下载新版本的sdk工具，它应该会很好。

Answer 2

我不知道摩托罗拉xoom，它w。但通常我得到编译时错误，因为根方法有一个参数。删除参数为“int root（）{”，它应该工作。

还有一件事：他们不工作在模拟器上，因为模拟器支持还没有。

Answer 3

是的。 Renderscript不会在模拟器上工作。运行相同的Android 3.0或更高版本的设备上。
