嘿，我正在尝试通过 URL 在动态壁纸中加载图像……这可能吗？如果是这样，你能告诉我为什么这段代码不起作用（日志 - “无法从以下位置加载位图：” + url）？谢谢！

c = holder.lockCanvas();
if (c != null) {
try {
final Bitmap b = BitmapUtils.loadBitmap("http://mw2.google.com/mw-panoramio/photos/medium/17287086.jpg");
c.drawBitmap(b, 0, 0, null);
} catch (Exception e) {
Log.e("Debug", e.toString());
}
}
