在我的应用程序中,我使用通用图像下载器 BaseImageDownloader 类来同步加载画廊的内容。对于来自 Imageloader.getInstance().loadImage 异步函数的相同内容,它不会给出任何安全异常并按原样加载图像,但是当我尝试使用 BaseImageDownloader 同步下载它(Imageloader.getInstance().loadImage() 也一样)我得到了这个安全异常

另外我搜索了代码,您在配置或其他地方没有获得任何许可,这是什么原因?
public Bitmap decodeSampledBitmapFromStream(String path, int reqWidth, int reqHeight) throws IOException {
BaseImageDownloader downloader = new BaseImageDownloader(getApplicationContext());
InputStream stream = downloader.getStream(path, null);
final BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
BitmapFactory.decodeStream(stream, new Rect(-1,-1,-1,-1), options);
stream.close();
options.inSampleSize = calculateInSampleSize(options, reqWidth, reqHeight);
options.inJustDecodeBounds = false;
stream = downloader.getStream(path, null);
Bitmap bitmap = BitmapFactory.decodeStream(stream, new Rect(-1,-1,-1,-1), options);
stream.close();
return bitmap;
}
