Java RenderScript支持库中缺少网格类
我下面是为了了解RenderScript。我在project.properties中添加了以下内容:Java RenderScript支持库中缺少网格类,java,android,eclipse,renderscript,Java,Android,Eclipse,Renderscript,我下面是为了了解RenderScript。我在project.properties中添加了以下内容: renderscript.target=19 renderscript.support.mode=true sdk.buildtools=23.0.2 我编写了我的.rs文件,ScriptC_myfilename是在gen文件夹中生成的,但是android.support.v8.renderscript无法解析为类型,因此我添加了renderscript-v8.jar作为库,该库位于sdk/b
renderscript.target=19
renderscript.support.mode=true
sdk.buildtools=23.0.2
我编写了我的.rs文件,ScriptC_myfilename是在gen文件夹中生成的,但是android.support.v8.renderscript
无法解析为类型,因此我添加了renderscript-v8.jar
作为库,该库位于sdk/build tools/android-4.4W/renderscript/lib(配置生成路径>>库>>添加外部JAR),问题已修复
编码后,由于此错误,我无法编译代码,该错误可在ScriptC_filename.java的gen文件夹中找到:
Mesh cannot be resolved to a Type
我搜索这个问题,试图找到缺少的类,我不知道,可能是手动实现这个类作为我项目的一部分,所以Eclipse可以导入它并修复错误,但我有点困惑,因为Mesh
类甚至没有被引用
我还尝试在sdk\build tools\android-4.4.2\renderscript\lib导入renderscript-v8.jar,以及添加import android.support.v8.renderscript.Mesh
,但没有成功
我不知道这是否有帮助,但这是我的ScriptC_Snow.java文件(这里的所有内容都是生成的,我没有编辑),注释是Eclipse上显示的错误

对于(int i=0;i提前感谢。您不能将支持库与rs\u graphics.rsh一起使用。它不支持诸如rs\u mesh、rs\u font或rs\u program*之类的对象。支持库仅用于访问RenderScript compute。您能发布您的RenderScript代码吗?哦,我现在明白了。mesh类已被弃用。但如果我不能使用re\u mesh,仍然会有问题例如,使用renderscript制作1000个粒子?我知道OpenGL,但renderscript看起来更好。你有什么建议吗?我想制作各种粒子的动画,只是为了学习。谢谢@StephenHines
