How to trigger MediaScan on Nexus 7?

Question

Because I want to make sure the MediaStore has the latest information without having to reboot I\'d like to trigger the MediaScanner using the popular way I found on SO

Answer 1

My answer is a little late, but it might help those, who save a new file, and would like to extend the media store by just that file on Android Kitkat: On Android Kitkat the intent ACTION_MEDIA_MOUNTED is blocked for non-system apps (I think, because scanning the whole filesystem is pretty expensive). But it is still possible to use the intent ACTION_MEDIA_SCANNER_SCAN_FILE to add a file to the media store:

File f = new File(path to the file you would like to add to the media store ...);
try {
    Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
    Uri uri = Uri.fromFile(f);
    mediaScanIntent.setData(uri);
    sendBroadcast(mediaScanIntent);
} catch(Exception e) {
    ... 
}
