How to Run Media Scanner in Android

Media scanning specific folder

Use below code to get the files from specific folder:

File folder_file = new File("give specific folder path");
    File[] files = folder_file.listFiles();
    if (files != null) {
        for (File file : files) {
            // checking the File is file or directory
            if (file.isFile()) {
                String path = file.getAbsolutePath();
                String extension = path
                        .substring(path.lastIndexOf(".") + 1);
                // if the file is audio type, then save it to the database
                if (extension.equalsIgnoreCase("mp4")) {
                    System.out.println(path + " is a media file ");
                }
            }
        }
    }

Try this for scanning files:

sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, Uri
                    .parse("file://"
                            + Environment.getExternalStorageDirectory())));

Trigger mediascanner on specific path (folder), how to?

Hey I found out how to do it with a very simple code.

Just call this line of code:

sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, Uri.parse("file://" + Environment.getExternalStorageDirectory())));

This should trigger mediascanner.
