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

Here's the sample code based on CommonsWare's answer:

MediaScannerConnection.scanFile(activity, new String[]{path}, null,
                                new MediaScannerConnection.OnScanCompletedListener() {
    @Override
    public void onScanCompleted(final String path, final Uri uri) {
        Log.i(TAG, String.format("Scanned path %s -> URI = %s", path, uri.toString()));
    }
});

Even though in most of the cases, where one knows the files to be added/updated/etc. to the MediaStore, one should follow CommonsWare's answer, I wanted to post the my solution where I need to do it the rough way because I don't know the file paths. I use this mostly for testing/demoing:

Uri uri = Uri.fromFile(Environment.getExternalStorageDirectory());
activity.sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, uri));

BTW, no permissions are necessary for either solution.
