android.renderscript.RSRuntimeException：加载ScriptC脚本失败。 （android sdk build tools 23.0.1）

Question

尝试在不使用支持库的情况下编译renderscript。 我正在使用Android Studio和android sdk构建工具23.0.1（我也有20和23.0.0）。试图为三星galaxy s5 plus编译它。 （Android 5.0.2 API 21）

inverse.rs文件位于： / SRC /主/ RS /

在我的mainactivity.java中：

RenderScript rs = RenderScript.create(this.getApplicationContext());
Allocation allocIn;
allocIn = Allocation.createFromBitmap(rs, bitmap);
Allocation allocOut = Allocation.createTyped(rs, allocIn.getType());
ScriptC_inverse inverse = new ScriptC_inverse(rs); //crashes on this line

inverse.forEach_invert(allocIn,allocOut);
rs.finish();
allocOut.copyTo(bitmap);

allocOut.destroy();
allocIn.destroy();
rs.destroy();

inverse.rs：

#pragma version(1)
#pragma rs java_package_name(com.example.dries.myocrtest)

uchar4 __attribute__((kernel)) invert(uchar4 in) {
  uchar4 out = in;
  out.r = 255 - in.r;
  out.g = 255 - in.g;
  out.b = 255 - in.b;
  return out;
}

build.gradle文件：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.1"

    defaultConfig {
        applicationId "com.example.dries.myocrtest"
        minSdkVersion 17
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"

        renderscriptTargetApi 23
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:23.0.1'
    compile project(':tesstwo')
    compile project(':fileExplorer')
}

这是我的错误日志：

Answer 1

将targetSdkVersion设置为S5支持的级别，因为23将使其仅在API级别23+设备上运行。我们不使用minSdkVersion。我们在编译RS时使用targetSdkVersion。
