Image directory not created when i take picture from my app

I am working in android studio. Building an app in which i am using a camera. When i run my app the app works fine. I capture the image it does captured the image. But the folder i created is not showing in my gallery. I am saving images in my local storage and not in SD CARD. I was very curious that why the folder is not created as it doesn't gives me any error so it should be in my gallery. So i restarted my device and after restarting i can see the folder in my gallery and the images taken in it. I again open the app and took images from it but again the images were not shown in the folder.

Below is my code in which i am making ta directory for saving images

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
 if(requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE)
    {
        if(resultCode == Activity.RESULT_OK)
        {
            Bitmap bmp = (Bitmap)data.getExtras().get("data");
            ByteArrayOutputStream stream = new ByteArrayOutputStream();

            bmp.compress(Bitmap.CompressFormat.JPEG, 100, stream);
            byte[] byteArray = stream.toByteArray();

            // convert byte array to Bitmap
            Bitmap bitmap = BitmapFactory.decodeByteArray(byteArray, 0, byteArray.length);

            if(isStoragePermissionGranted())
            {
                SaveImage(bitmap);
            }


        }

}
 private void SaveImage(Bitmap finalBitmap) {

    String root = Environment.getExternalStorageDirectory().getAbsolutePath().toString();
    Log.v(LOG_TAG, root);
    File myDir = new File(root + "/captured_images");
    myDir.mkdirs();
    Random generator = new Random();
    int n = 1000;
    n = generator.nextInt(n);
    String fname = "Image-" + n + ".jpg";
    File file = new File(myDir,fname);
    if (file.exists())file.delete();
    try {
        FileOutputStream out = new FileOutputStream(file);
        finalBitmap.compress(Bitmap.CompressFormat.JPEG,100,out);
        out.flush();
        out.close();


    } catch (Exception e) {
        e.printStackTrace();
    }

}

Below is the picture of my debugging

enter image description here

**Note: **

As i am using native camera so the pictures are saved in the camera roll folder i.e. the default folder in my device. But the image saved there is not the compressed one, the compress image should be saved in my created folder.

I am stuck to it and don't know what to do.

Any help would be highly appreciated.

You need to invoke scanFile(Context context, String[] paths, String[] mimeTypes, MediaScannerConnection.OnScanCompletedListener callback) method of MediaScannerConnection.

MediaScannerConnection provides a way for applications to pass a newly created or downloaded media file to the media scanner service. This will update your folder with the newly saved media.

    private void SaveImage(Bitmap finalBitmap) {

        //....
        if(!storageDir.exists()){
               storageDir.mkdirs();
         }
        //...
        file.createNewFile();
        try {
            MediaScannerConnection.scanFile(context, new String[]  {file.getPath()} , new String[]{"image/*"}, null);
            FileOutputStream out = new FileOutputStream(file);
            finalBitmap.compress(Bitmap.CompressFormat.JPEG,100,out);
            out.flush();
            out.close();
        } catch (Exception e) {
            e.printStackTrace();
        }

    }

try this

private void saveBitmap(Bitmap bitmap) {
        String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
        String imageFileName = timeStamp + ".jpg";
        File storageDir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
        final String fileLoc = storageDir.getAbsolutePath() + "/folderName/" + imageFileName;
        File file = new File(fileLoc);
        OutputStream os = null;
        try {
            os = new BufferedOutputStream(new FileOutputStream(file));
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }
        bitmap.compress(Bitmap.CompressFormat.JPEG, 100, os);
        try {`enter code here`
            os.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
