很多對renderscript的調用會產生錯誤「創建的RS線程數量少於預期數量」

Question

我有一個帶有許多項目和圖像的微調器的應用程序。

每當用戶選擇列表中的項目時，將執行一個數字（1到5）的renderscript腳本來更改圖像的像素。

做出大約30個選擇後，應用程序崩潰並出現錯誤。

這是堆棧跟蹤。

我想我應該以某種方式關閉renderscript使用的非平民線程或什麼？

UPDATE：

有時誤差是不同的：

它指向的線

 ScriptC_BrightnessContrast script = new ScriptC_BrightnessContrast(rs, context.getResources(), 
      R.raw.brightnesscontrast); 

更新2：

這是Brightness conrast過濾器。 我想，每次吃內存時都會創建新的輸入輸出分配和Script對象。是否可以使用一個分配來執行一系列renderscript動作？例如，我從位圖進行分配，然後對其應用brightnesscontrastfilter，然後使用類似實現的一些不同的過濾器？

public Bitmap brightnessContrastRs(Bitmap bmIn, int brightness, int contrast, Context context) 
{ 
    Bitmap bmOut = Bitmap.createBitmap(bmIn.getWidth(), bmIn.getHeight(), 
      bmIn.getConfig()); 
// RenderScript rs = RenderScript.create(context); 
    Allocation allocIn; 
    allocIn = Allocation.createFromBitmap(rs, bmIn, 
      Allocation.MipmapControl.MIPMAP_NONE, 
      Allocation.USAGE_SCRIPT); 
    Allocation allocOut = Allocation.createTyped(rs, allocIn.getType()); 
    ScriptC_BrightnessContrast script = new ScriptC_BrightnessContrast(rs, context.getResources(), 
      R.raw.brightnesscontrast); 
    script.set_in(allocIn); 
    allocIn.destroy(); 
    script.set_out(allocOut); 
    script.set_script(script); 
    float rowContrast = ((100.0f + contrast) * (100.0f + contrast)/10000.0f); 
    float rowBrightness = brightness/255.f; 
    script.set_rowBrightness(rowBrightness); 
    script.set_rowContrast(rowContrast); 
    script.invoke_filter(); 
    allocOut.copyTo(bmOut); 
    allocOut.destroy(); 
    return bmOut; 
} 

除此之外的一些動作內我有相當大的INT陣列（360000個整數），如我理解每次我創建小號criptC對象它爲每一個陣列，所述的renderScript內部限定分配內存時間，因此存儲器可以泄漏相當快。

當我發佈這個問題時，每次創建RenderScript對象的註釋行都沒有被註釋，並且內存泄漏速度更快。

例如這裏是RS使用數組文件（其他文件與此類似，但可能不包含數組）

rs_allocation out; 
rs_allocation in; 
rs_script script; 

float opacity; 
float alphas[360000]; 
int width; 

void root(const uchar4* v_in, uchar4* v_out, const void* usrData, uint32_t x, 
     uint32_t y) 
{ 
    float4 current = rsUnpackColor8888(*v_in); 
    current.a = alphas[width * y + x] * opacity; 
    *v_out = rsPackColorTo8888(current.r, current.g, current.b, current.a); 
} 
void filter() 
{ 
#if !defined(RS_VERSION) || (RS_VERSION < 14) 
rsForEach(script, in, out, 0); 
#else 
rsForEach(script, in, out); 
#endif 
} 

Answer 1

是真的花了很多的內存每次都創建一個新的ScriptC對象。我將它們移到了類字段變量並且一直運行正常。
