That depends on the loader, but I don't think Fresco or Glide support it.
If you use Fresco, this could be caused by not initialize Fresco.
实现 ImageLoader 子类，下载解密后，把解密的文件回调出去。
I verified that it worked fine on Pixel, which device are you using?
How about save an image in png or gif format? @moodcal
Yeah, that's true. It worked on Google Photos when I tested on Pixel, so I didn't add that logic. Looks like necessary now. My idea is parsing file header, but...
That's very easy to break, many social media don't have extension in their image url.
你准备一个可复现的 demo？
好的，有时间之后我看看。不过最近我可能都没时间，要不你先调试看看？
