Image 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 and return it back   Do you have any idea why is it so   Seems like the Gallery application has some cache that isn t updated on file save     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

You need to give permissions to the Gallery app  Just long press the gallery app icon in the home screen and tap on  APP INFO  that pops up at the top of the screen  Doing it will show the gallery app settings  Now go in Permissions tab and enable the storage  camera permissions by toggling it  Now go to your native gallery app and you will get the your saved images

My answer to the original question and to anyone else that may have this problem   I was having this same problem  images in my app that people saved to the SD card were not showing up in their Gallery immediately  After some searching I found this one line of code inserted after my  save to sdcard  code that fixed the problem   sendBroadcast new Intent Intent ACTION MEDIA MOUNTED  Uri parse  file      Environment getExternalStorageDirectory

A simpler solution is to use the static convenience method scanFile     File imageFile       MediaScannerConnection scanFile this  new String     imageFile getPath      new String      image jpeg     null     where this is your activity  or whatever context   the mime-type is only necessary if you are using non-standard file extensions and the null is for the optional callback  which we don t need for such a simple case
