从文件加载图像时出现OutOfMemoryError

Question

我知道这个question，从我所知道的情况来看，我实际上做的与最佳答案建议的一样。但是我仍然在内存较少的设备上遇到outOfMemory崩溃。

编辑：我只是用手机原生相机拍照。没什么好的。

private Bitmap setImgViewFromFile(ImageView imgView, String file) {
    // Get the dimensions of the View
    int targetW = Math.max(imgView.getWidth(), 600);
    int targetH = Math.max(imgView.getHeight(), 800);


    // Get the dimensions of the bitmap
    BitmapFactory.Options bmOptions = new BitmapFactory.Options();
    bmOptions.inJustDecodeBounds = true;
    BitmapFactory.decodeFile(file, bmOptions);
    int photoW = bmOptions.outWidth;
    int photoH = bmOptions.outHeight;

    // Determine how much to scale down the image
    int scaleFactor = Math.min(photoW / targetW, photoH / targetH);

    // Decode the image file into a Bitmap sized to fill the View
    bmOptions.inJustDecodeBounds = false;
    bmOptions.inSampleSize = scaleFactor;
    bmOptions.inPurgeable = true;

    Bitmap bitmap = BitmapFactory.decodeFile(file, bmOptions);
    imgView.setImageBitmap(bitmap);
    return bitmap;
}

Stacktrace：

谁能看到我做错了什么？
