加载RS jni库时出错:UnsatisfiedLinkError:无法加载RSSupport:findLibrary返回null

Question

将RenderScript与支持库一起使用时,我在Motorola iRazr(Android 4.1.2)上出现此错误

Error loading RS jni library: java.lang.UnsatisfiedLinkError: Couldn't load RSSupport: findLibrary returned null

三星Galaxy S3上的一切正常.

        Bitmap outputBitmap = Bitmap.createBitmap(inputBitmap);

        RenderScript rs = RenderScript.create(ctx);

        ScriptIntrinsicBlur theIntrinsic = ScriptIntrinsicBlur.create(rs, Element.U8_4(rs));

        Allocation tmpIn = Allocation.createFromBitmap(rs, inputBitmap);
        Allocation tmpOut = Allocation.createFromBitmap(rs, outputBitmap);

        theIntrinsic.setRadius(BLUR_RADIUS);
        theIntrinsic.setInput(tmpIn);
        theIntrinsic.forEach(tmpOut);

        tmpOut.copyTo(outputBitmap);

我使用的支持库jar是

build-tools/19.0.1/renderscript/lib/renderscript-v8.jar

任何帮助深表感谢.

编辑:

我将这些文件复制到libs文件夹中,并验证了so文件是否在设备上的data/data/lib文件夹中.

librsjni.so和 libRSSupport.so存在于设备上...

Answer 1

您不必使用库build-tools/19.0.1/renderscript/lib/renderscript-v8.jar(删除它),正如Google团队在此处所说,您只需在project.properties文件中包含以下行:

renderscript.target=18
renderscript.support.mode=true
sdk.buildtools=19.0.3

我希望这能帮到您.

据 Tim Murray（负责 Android 渲染脚本支持的人）称，这将在下一个构建工具版本（可能是 19.1.1）中修复。
