RSRuntimeException：加载 ScriptC 脚本失败（构建工具 19.0.2）

Question

这是我的全部输出：

这是我的 build.gradle 文件的一部分：

defaultConfig {
        minSdkVersion 14
        targetSdkVersion 19
        renderscriptTargetApi 19
        renderscriptSupportMode=true
    } 

在将我的构建工具更新到 19.0.2 之前，我收到了针对每个错误的 rs，该错误已通过最新的构建工具版本 (https://code.google.com/p/android/issues/detail?id=64110) 得到修复。现在我完全不知道为什么它不能在非 4.4 手机（需要向后兼容的手机，也就是支持库）上运行。这与每个 rs 的问题是否相同，还是我只是遗漏了什么？

似乎在 ScriptC.java 文件中失败了：

protected ScriptC(RenderScript rs, Resources resources, int resourceID) {
        super(0, rs);
        int id = internalCreate(rs, resources, resourceID);
        if (id == 0) {
            throw new RSRuntimeException("Loading of ScriptC script failed.");
        }
        setID(id);
    }

ScriptC_processing: 41:

 public  ScriptC_processing(RenderScript rs, Resources resources, int id) {
        super(rs, resources, id);
        __ALLOCATION = Element.ALLOCATION(rs);
        __SCRIPT = Element.SCRIPT(rs);
        __U32_2 = Element.U32_2(rs);
        __SAMPLER = Element.SAMPLER(rs);
        __F32_2 = Element.F32_2(rs);
        __I32 = Element.I32(rs);
        __F32 = Element.F32(rs);
        __U8_4 = Element.U8_4(rs);
    }

编辑：这里似乎设置了 id：

protected ScriptC(RenderScript rs, Resources resources, int resourceID) {
    super(0, rs);

    if (rs.isNative) {
        RenderScriptThunker rst = (RenderScriptThunker)rs;
        ScriptCThunker s = new ScriptCThunker(rst, resources, resourceID);
        mT = s;
        return;
    }

    int id = internalCreate(rs, resources, resourceID);
    if (id == 0) {
        throw new RSRuntimeException("Loading of ScriptC script failed.");
    }
    setID(id);
}

感谢 Stephen Hines 的评论，这是因为我的目标 api 设置为 19。
