我将RenderScript支持库与SDK Tools 22.6.2、Build Tools 19.0.3一起使用。它在4.1设备上运行良好，甚至在2.3设备上也运行良好

project.properties

target=android-19
renderscript.target=19
renderscript.support.mode=true
sdk.buildtools=19.0.3

我试图降低生成工具版本，但该项目无法使用

RenderScript支持模式下的生成工具19.0.3或更高版本进行生成。

错误

如果我将

.so

文件复制到

libs

目录，它会开始抱怨重复的文件

生成最终归档文件时出错：找到APK:lib/armeabi-v7a/librsjni.so的重复文件

我不熟悉使用RenderScript。有什么建议吗？
这意味着2.3版不提供super class。检查是否在android 2.2及更低版本上运行，如果没有，则表示这是sipport库问题。这需要检查可用的android支持库
我猜RenderScript不是2.3 Emulator映像的一部分。
