RenderScript代碼不能在沒有rsDebug的情況下工作

我對RenderScript完全陌生。我試圖在http://www.youtube.com/watch?v=5jz0kSuR2j4工作中得到Romain Guy顯示的一個簡單示例。RenderScript代碼不能在沒有rsDebug的情況下工作

首先，這是代碼。

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); 
    }

，最後的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包含鬱金香。 JPG。你不會在Romain Guy的代碼中找到我在gray.rs中添加的rsDebug（）語句。

無論如何，代碼編譯，有或沒有rsDebug（）。但是，當我嘗試在設備上運行應用程序時，問題就開始了。

我試圖在運行Android 4.4的Nexus 4上運行該應用程序。使用所示的代碼，它工作正常，我得到一個灰度圖像。但是，如果我註釋掉rsDebug（）行，該應用程序不起作用。我只是得到一個黑屏。

這裏是logcat輸出。

我無法理解調試語句是如何影響的方式，其中，應用運行。任何幫助，爲什麼我面臨這個問題將不勝感激。

所以這是我的問題的第一部分。

第二部分：當我嘗試在運行Android 4.1.2的Galaxy Note 10.1 N8013上運行完全相同的代碼並且在運行Android 4.1.2的APQ8064的另一塊硬件上運行時，該應用程序無法運行。

這裏的logcat的輸出與我的硬件：

最後，這裏是一個與三星平板的logcat的輸出：

這就是它。如果任何人有任何想法如何解釋這一點，請讓我知道。

謝謝！

你可以嘗試沒有rsDebug，但與強制CPU的setprop？「adb shell setprop debug.rs.default-CPU-driver 1」 –

感謝您的回覆Jason。這使得我的Nexus 4上的應用程序工作。沒有運氣在其他設備上。但是，我的答案有問題。我開始使用RenderScript的主要原因是希望能夠在GPU上完成一些計算。我知道無法強制RenderScript在GPU上運行。但是不會強制我的應用程序只能在CPU上運行？ – Akshay

這不是一個答案，我只是想縮小發生了什麼。這看起來像一個bug，但我無法從這裏的位複製它。如果您可以在https://code.google.com/p/android/issues/list上提交apk錯誤，我會進一步瞭解它。 –

我剛剛遇到同樣的問題。當rsDebug處於同一個函數的某個位置時，它似乎被修復了。這對我來說是固定的：

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

    /* Code */ 
}

使用這個，rsDebug從來沒有實際調用，所以它不會輸出任何東西。

注意這不起作用：

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

這可能是最優化的。
