保存到 sdcard 的图像不会出现在 Android 的图库应用中 [英] Image, saved to sdcard, doesn't appear in Android's Gallery app

问题描述

我将图像保存到 sdcard 中，但在我取出 sdcard 并将其返回之前，它不会出现在 Gallery 应用程序中.

I save an image to the sdcard and it doesn't appear in the Gallery application until I pull off the sdcard and return it back.

你知道为什么会这样吗?

Do you have any idea why is it so?

似乎 Gallery 应用程序有一些缓存，但不会在文件保存时更新...

Seems like the Gallery application has some cache that isn't updated on file save...

实际上，我也想在图库应用程序中打开刚刚保存的图像，但没有成功
this 是我关于这个问题的问题.

Actually, I also want to open the just-saved image in Gallery application and have no success with that
this is my question about this issue.
