Image once saved to sdcard doesn t appear in Android s Gallery app

Question

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

why so?

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

The system scans the SD card when it is mounted to find any new image (and other) files. If you are programmatically adding a file, then you can use this class:
