Android picture saved to SD card not showing in Gallery

问题

Currently I have a program that takes pictures and saves them as a jpg on the top level of the sdcard, but its not appearing in the Gallery. Is there something I must do to make it happen?

回答1:

You need to call the MediaScanner so that it knows your file exists:

File file; // = your file
String mimetype; // = your file's mimetype. MimeTypeMap may be useful.
MediaScanner.scanFile(getApplicationContext(), new String[]{file.getPath()}, new String[]{mimetype}, null);

Try this answer. Working for me

context.sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.fromFile(finalFile)));

Maybe someone is "overseeing" it...
