首先让我说我的所有SDK包都是22.3版本的最新版本,包括Ecplise ADT和Build-Tools 19.0.0.

我的目的是在各种AndroID平台上实现一些高计算图像算法,可能从API 8开始.为此,我在我的Ecplise项目中设置了对renderscript-v8库的引用,同时将应用程序定位到API 19.

我有两个AndroID设备要测试,第一个是AndroID 4.3(API 18),第二个是AndroID 2.2(API 8).我在运行这段代码时遇到了不同的异常,它调用了ScriptIntrinsicYuvToRGB(代码部分取自Executing ScriptIntrinsicYuvToRgb问题)：

/* --------------   global vars */private RenderScript rs;private ScriptIntrinsicYuvToRGB rs_YUVtoRGB;private Allocation rs_YUVtoRGB_in;private Allocation rs_YUVtoRGB_out;  /* --------------in constructor... */this.rs = RenderScript.create(this.getContext());this.rs_YUVtoRGB = ScriptIntrinsicYuvToRGB.create(this.rs,Element.U8_4(rs));Type.Builder tb_in = new Type.Builder(this.rs,Element.createPixel(this.rs,Element.DataType.UNSIGNED_8,Element.DataKind.PIXEL_YUV));tb_in.setX(prevWIDth);tb_in.setY(prevHeight);tb_in.setMipmaps(false);tb_in.setYuvFormat(this.camera.getParameters().getPrevIEwFormat());this.rs_YUVtoRGB_in = Allocation.createTyped(this.rs,tb_in.create(),Allocation.USAGE_SCRIPT);Type.Builder tb_out = new Type.Builder(this.rs,Element.RGBA_8888(this.rs));tb_out.setX(prevWIDth);tb_out.setY(prevHeight);tb_out.setMipmaps(false);this.rs_YUVtoRGB_out = Allocation.createTyped (this.rs,tb_out.create(),Allocation.USAGE_SCRIPT);/* --------------launching the script... */// byte[] raw... // a YUV imagethis.rs_YUVtoRGB_in.copyFrom(raw);this.rs_YUVtoRGB.setinput(this.rs_YUVtoRGB_in);this.rs_YUVtoRGB.forEach(this.rs_YUVtoRGB_out);int[] framePixels = new int[prevIEwSize.wIDth * prevIEwSize.height];this.rs_YUVtoRGB_out.copyTo(framePixels);  // final RGB converted image

Eclipse设法编译它(它应该意味着库被很好地引用),但……

AndroID 4.3失败于：Type.Builder tb_in = new Type.Builder(this.rs,Element.DataKind.PIXEL_YUV));使用不受支持的DataKind

在AndroID 2.2上,它在init阶段失败：加载RS jni库时出错：java.lang.UnsatisfIEdlinkError：找不到库RSSupport

谢谢您的帮助

解决方法 createPixel()的错误是ElementThunker.java中的实际错误.它缺少PIXEL_YUV的情况,因此最终返回null而不是相应的类型.我将在AOSP和未来的SDK版本中修复此问题. (补丁是在 https://android-review.googlesource.com/70810).

至于库加载问题,我相信你的另一个问题,你注意到你的Application.mk文件没有为所有架构构建(因此没有捆绑适当的共享库).它在4.3上工作的原因是4.3自动拥有libRSSupport.so的副本(虽然它确实不应该).较旧的设备显然没有.so的默认/ system / lib /副本,因此除非你的构建实际上用apk打包它,否则它们总是无法加载它.
