android.renderscript.RSRuntimeException：加載ScriptC腳本失敗。 （android sdk build tools 23.0.1）

Question

嘗試在不使用支持庫的情況下編譯renderscript。 我正在使用android studio與android sdk構建工具23.0.1（我也有20和23.0.0）。試圖編譯它爲三星galaxy s5 plus。 （5.0.2的Android API 21）

的inverse.rs文件位於： /SRC /主/ RS/

以我mainactivity.java：

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; 
} 

的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') 
} 

這是我的錯誤日誌：

Answer 1

設置targetSdkVersion您S5的支持水平，23會造成這是隻在API層面23+設備可運行。我們不使用minSdkVersion。編譯RS時，我們使用targetSdkVersion。
