RenderScript代码不能在没有rsDebug的情况下工作

我对RenderScript完全陌生。我试图在http://www.youtube.com/watch?v=5jz0kSuR2j4工作中得到Romain Guy显示的一个简单示例。RenderScript代码不能在没有rsDebug的情况下工作

首先，这是代码。

MainActivity.java

package com.example.rsgray; 

    import android.app.Activity; 
    import android.graphics.Bitmap; 
    import android.graphics.BitmapFactory; 
    import android.os.Bundle; 
    import android.renderscript.Allocation; 
    import android.renderscript.RenderScript; 
    import android.view.Window; 
    import android.view.WindowManager; 
    import android.widget.ImageView; 
    import android.widget.ImageView.ScaleType; 

    public class MainActivity extends Activity { 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN); 
    requestWindowFeature(Window.FEATURE_NO_TITLE); 
    ImageView iv = new ImageView(this); 
    iv.setScaleType(ScaleType.CENTER_CROP); 
    setContentView(iv); 

    drawGrayScale(iv, R.drawable.tulips); 
} 

private void drawGrayScale(ImageView iv, int image) { 
    Bitmap in = BitmapFactory.decodeResource(getResources(), image); 
    Bitmap out = Bitmap.createBitmap(in.getWidth(), in.getHeight(), in.getConfig()); 

    RenderScript rs = RenderScript.create(MainActivity.this); 
    Allocation inAlloc = Allocation.createFromBitmap(rs, in); 
    Allocation outAlloc = Allocation.createTyped(rs, inAlloc.getType()); 

    ScriptC_gray script = new ScriptC_gray(rs, getResources(), R.raw.gray); 
    script.set_in(inAlloc); 
    script.set_out(outAlloc); 
    script.set_script(script); 

    script.invoke_filter(); 

    outAlloc.copyTo(out); 
    iv.setImageBitmap(out); 
}

}

gray.rs

#pragma version(1) 
    #pragma rs java_package_name(com.example.rsgray) 
    #pragma rs_fp_relaxed 

    rs_allocation in; 
    rs_allocation out; 
    rs_script script; 

    const static float3 gray = { 0.3f, 0.6f, 0.1f }; 

    void root(const uchar4* v_in, uchar4* v_out, const void* usrData, uint32_t x, uint32_t y) { 
     rsDebug("gray.rs", rsUptimeMillis()); 
     float4 inPixel = rsUnpackColor8888(*v_in); 
     float3 result = dot(inPixel.rgb, gray); 
     *v_out = rsPackColorTo8888(result); 
    } 


    void filter() { 
     rsForEach(script, in, out); 
    }

，最后的AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
package="com.example.rsgray" 
android:versionCode="1" 
android:versionName="1.0" > 

<uses-sdk 
    android:minSdkVersion="16" 
    android:targetSdkVersion="16" /> 

<application 
    android:allowBackup="true" 
    android:icon="@drawable/ic_launcher" 
    android:label="@string/app_name" 
    android:theme="@style/AppTheme" > 
    <activity 
     android:name="com.example.rsgray.MainActivity" 
     android:label="@string/app_name" > 
     <intent-filter> 
      <action android:name="android.intent.action.MAIN" /> 

      <category android:name="android.intent.category.LAUNCHER" /> 
     </intent-filter> 
    </activity> 
</application> 

</manifest>

RES /抽拉-nodpi包含郁金香。 JPG。你不会在Romain Guy的代码中找到我在gray.rs中添加的rsDebug（）语句。

无论如何，代码编译，有或没有rsDebug（）。但是，当我尝试在设备上运行应用程序时，问题就开始了。

我试图在运行Android 4.4的Nexus 4上运行该应用程序。使用所示的代码，它工作正常，我得到一个灰度图像。但是，如果我注释掉rsDebug（）行，该应用程序不起作用。我只是得到一个黑屏。

这里是logcat输出。

我无法理解调试语句是如何影响的方式，其中，应用运行。任何帮助，为什么我面临这个问题将不胜感激。

所以这是我的问题的第一部分。

第二部分：当我尝试在运行Android 4.1.2的Galaxy Note 10.1 N8013上运行完全相同的代码并且在运行Android 4.1.2的APQ8064的另一块硬件上运行时，该应用程序无法运行。

这里的logcat的输出与我的硬件：

最后，这里是一个与三星平板的logcat的输出：

这就是它。如果任何人有任何想法如何解释这一点，请让我知道。

谢谢！

你可以尝试没有rsDebug，但与强制CPU的setprop？ “adb shell setprop debug.rs.default-CPU-driver 1” –

感谢您的回复Jason。这使得我的Nexus 4上的应用程序工作。没有运气在其他设备上。但是，我的答案有问题。我开始使用RenderScript的主要原因是希望能够在GPU上完成一些计算。我知道无法强制RenderScript在GPU上运行。但是不会强制我的应用程序只能在CPU上运行？ – Akshay

这不是一个答案，我只是想缩小发生了什么。这看起来像一个bug，但我无法从这里的位复制它。如果您可以在https://code.google.com/p/android/issues/list上提交apk错误，我会进一步了解它。 –

我刚刚遇到同样的问题。当rsDebug处于同一个函数的某个位置时，它似乎被修复了。这对我来说是固定的：

if(x > 0) { 
    if(x < 0) { 
     rsDebug("Workaround for renderscript bug", 0.0f); 
    } 

    /* Code */ 
}

使用这个，rsDebug从来没有实际调用，所以它不会输出任何东西。

注意这不起作用：

if(0) { 
    rsDebug("Workaround for renderscript bug", 0.0f); 
}

这可能是最优化的。
