更新Android图库 [英] Update Android Gallery
问题描述
我正在开发一个Android应用程序，它读取外部存储的图像进行图像处理，将创建外部STORGE图片的新文件夹，在其中存储经过处理的图像。
I am developing an Android app which reads images from external storage for image processing, creates a new folder in "pictures" on external storge and stores the processed images in it.
它采用标准的Android画廊很长一段时间，甚至重新启动才能识别新的文件夹中。
It takes the standard android gallery a long time or even a reboot to recognize the new folder.
有没有一种方法来更新编程，所以我的新文件夹会从画廊认可的Android图库？
Is there a way to update android gallery programmatically so my new folder gets recognized from gallery?
推荐答案
触发的mediascanner再次读取所有的媒体文件。用这块code的：
Trigger the mediascanner to read all the media files again. Use this piece of code :
sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, Uri.parse("file://" + Environment.getExternalStorageDirectory())));
这是非常低效的，虽然，因为它会首先读取整个SD卡更改。
This is very inefficient though since it'll begin reading the entire SDCard for changes.
