在Android中使用相機拍攝照片時出現致命的信號11和奇怪的錯誤信息

我試圖用相機拍照，修改拍攝的圖像，然後在用戶點擊接受後在相機中將修改的圖像顯示給用戶。這裏是我的代碼，上面那裏我做了創建該錯誤代碼更改評論：在Android中使用相機拍攝照片時出現致命的信號11和奇怪的錯誤信息

private class TakePictureThread extends Thread { 
    private Camera.PictureCallback pPictureCallback; 

    @Override 
    public void run() { 

     pPictureCallback = new PictureCallback() { 

      @Override 
      public void onPictureTaken(byte[] data, Camera camera) { 

       CameraInfo info = new CameraInfo(); 
       Camera.getCameraInfo(0, info); 

       SurfaceView surfaceView = mCameraCaptureView.getSurfaceView(); 

       // TODO: scale this such that we don't need to scale the cropped image 
       Bitmap unrotatedRawImage = 
         ImageUtils.decodeSampledBitmap(data, 
           surfaceView.getWidth(), 
           surfaceView.getHeight(), Bitmap.Config.RGB_565); 
       Bitmap rawImage = 
         ImageHelper.rotate(unrotatedRawImage, info.orientation); 
       unrotatedRawImage.recycle(); 

       mCroppedImage = cropRawCapturedImage(rawImage); 
       rawImage.recycle(); 

       mCroppedImage = Bitmap.createScaledBitmap(
         mCroppedImage, 
         ImageSize.CARD.getPixelWidth(), 
         ImageSize.CARD.getPixelHeight(), 
         false); 

       mImagePreview.setImageBitmap(mCroppedImage); 

       if (useBlurringAndGradient()) { 
        //new code 
        Bitmap blurredBitmap = ImageUtils.blurImage(mCroppedImage); 
        mImagePreview.setImageBitmap(blurredBitmap); 
       } 

       handlePhotoTaken(); 
      } 
     }; 

     mCameraCaptureView.getCamera().takePicture(null, null, pPictureCallback); 
    } 
}

而且blurImage方法：

/** 
* Performs the max blur possible 20 times on the bitmap provided. 
*/ 
static private Bitmap blurCardImage(Bitmap bitmap) { 
    RenderScript rs = RenderScript.create(MainApp.getInstance()); 

    Bitmap blurredBitmap = 
      Bitmap.createBitmap(bitmap.getWidth(), bitmap.getHeight(), Config.ARGB_8888); 

    for (int i = 0; i < 20; i++) { 
     Allocation allIn = Allocation.createFromBitmap(rs, bitmap); 
     Allocation allOut = Allocation.createFromBitmap(rs, blurredBitmap); 

     ScriptIntrinsicBlur blurScript = ScriptIntrinsicBlur.create(rs, Element.U8_4(rs)); 
     blurScript.setRadius(25.f); 

     blurScript.setInput(allIn); 
     blurScript.forEach(allOut); 

     allOut.copyTo(blurredBitmap); 

     bitmap = blurredBitmap; 
    } 

    rs.destroy(); 

    return bitmap; 
}

@ ben75我將日誌更新爲詳細級別。 – mpellegr 2014-10-20 14:22:31

爲什麼這會降低投票率？如有必要，我可以提供更多細節。 – mpellegr 2014-10-23 19:49:34

原來的答案是沒有產生正確的位圖輸出我期待所以我改變了這部分：

if (useBlurringAndGradient()) { 
    Bitmap blurredBitmap = ImageUtils.blurImage(mCroppedImage); 
    mImagePreview.setImageBitmap(blurredBitmap); 
}

這樣：

if (useBlurringAndGradient()) { 
    mImagePreview.buildDrawingCache(); 
    Bitmap bitmap = mImagePreview.getDrawingCache(); 
    Bitmap blurredBitmap = ImageUtils.blurImage(bitmap); 
    mImagePreview.setImageBitmap(blurredBitmap); 
}

這也固定崩潰我正在和我再也看不到在日誌的警告。有誰知道這個問題解決了我的問題的原因？
