runOnUiThread和Flir One SDK發生OutOfMemory錯誤

我試圖保存在FrameProcessor.Delegate.onFrameProcessed上收到的幀。runOnUiThread和Flir One SDK發生OutOfMemory錯誤

如果我嘗試使用runOnUiThread使用renderedImage.getFrame().save(...)線程內，我得到以下異常：

    at java.lang.ThreadGroup.uncaughtException(ThreadGroup.java:690)

這是做原來的線程的方法：

private FrameProcessor.Delegate frameProcessorDelegate = new FrameProcessor.Delegate() { 
    @Override 
    public void onFrameProcessed(final RenderedImage renderedImage) { 
     //Capture this image if requested 
     if (imageCaptureRequested) { 
      imageCaptureRequested = false; 
      setProgressVisibility(VISIBLE); 

      new Thread(new Runnable() { 
       public void run() { 
        String path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES).toString(); 
        SimpleDateFormat sdf = new SimpleDateFormat("yyMMdd-HHmmss", Locale.getDefault()); 
        String formatedDate = sdf.format(new Date()); 
        String fileName = formatedDate + ".jpg"; 
        try { 
         lastSavedPath = path + "/" + fileName; 

         renderedImage.getFrame().save(new File(lastSavedPath), RenderedImage.Palette.Iron, RenderedImage.ImageType.BlendedMSXRGBA8888Image); 

         toggleConfirmPhotoScreen(true, lastSavedPath); 
        } catch (Exception e) { 
         e.printStackTrace(); 
        } 
       } 
      }).start(); 
     } 
    } 
};

的方法使用runOnUiThread：

private void toggleConfirmPhotoScreen(final boolean show, final String lastSavedPath) { 
    //works until here 
    Log.d("ExampleApp", "toggleConfirmPhotoScreen"); 
    ((Activity) getContext()).runOnUiThread(new Runnable() { 
     @Override 
     public void run() { 
      //NEVER REACHES HERE 
      Log.d("ExampleApp", "  " + show + " CancelConfirmScreen"); 
     } 
    }); 
}

因爲你可以se e在代碼中的評論中，toggleConfirmPhotoScreen被調用，但runOnUiThread裏面什麼也沒有，當我想到OutOfMemoryException發生時。
