My intention was to do something that would make the "Photos" app see my stored videos. This (MediaScannerConnection) doesn't appear to be doing it, and I haven't seen any real confirmation that it's even supposed to do it. What is the point of doing this? I'm going to guess that if I just change the subdir name I write to to "Camera", then "Photos" will see my videos. > > Regards > > > On Tuesday, December 22, 2015 at 5:29:36 AM UTC+11, David Karr wrote: >> >> On Monday, December 21, 2015 at 12:08:57 AM UTC-8, gjs wrote: >>> >>> Hi, >>> >>> If your phone is not a Google Nexus variety then that's not surprising, >>> but Environment.getExternalStoragePublicDirectory(Environment. >>> DIRECTORY_DCIM) is what's recommended. >>> >>> In some respects it does not really matter which folder you use to store >>> media generated by your app (*), provided you go to the trouble of >>> 'cataloging' the media generated using MediaScannerConnection - >>> http://developer.android.com/reference/android/media/MediaScannerConnection.html#scanFile(android.content.Context, >>> >>> java.lang.String[], java.lang.String[], >>> android.media.MediaScannerConnection.OnScanCompletedListener) then your >>> photos / video will quickly show up in the default 'Photos' app, without >>> having to wait for it to scan the device periodically to find new media >>> files. >>> >>> (*) And is some other respects it really, really does matter what folder >>> you use - if you don't want the media files deleted when your app in >>> uninstalled (!)
