Using the static scanFile() method

If you simply need to know when the files have been added, you could use MediaScannerConnection’s static method scanFile() together with a MediaScannerConnection.OnScanCompletedListener.

The static method scanFile() is badly named, as it actually takes an array of paths and thus can be used to add multiple files at once and not just one – but it nevertheless does what we want 🙂

Here’s how to use this method:

private void scanWithPath(Context cont, String[] paths){
        MediaScannerConnection.OnScanCompletedListener callback = new MediaScannerConnection.OnScanCompletedListener() {
            @Override
            public void onScanCompleted(String path, Uri uri) {
                //this method get trigger for every path in the paths, not when finish scanning the whole paths 
            }
        };

        MediaScannerConnection.scanFile(cont, paths, null, callback);
    }
