Show the saved images in gallery

Question

I am creating a directory to store the bitmap images.This is my code:

 String root = Environment.getExternalStorageDirectory().toString();
                File myDir = new File(root + "/ABC");
                myDir.mkdirs();
                Random generator = new Random();
                int n = 10000;
                n = generator.nextInt(n);
                String fname = "Image-" + n + ".jpg";
                File file = new File(myDir, fname);
                Log.i(TAG, "" + file);
                if (file.exists())
                    file.delete();
                try {
                    FileOutputStream out = new FileOutputStream(file);
                    bitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
                    out.flush();
                    out.close();
                } catch (Exception e) {
                    e.printStackTrace();
                }

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

You should invoke the media scanner for the new file. One line of code. Please google for it. — greenapps, Sep 12 '16 at 06:55

Use this broadcast

   if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
                    Intent mediaScanIntent = new Intent(
                            Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
                    Uri contentUri = Uri.fromFile(out); //out is your file you saved/deleted/moved/copied
                    mediaScanIntent.setData(contentUri);
                    this.sendBroadcast(mediaScanIntent);
                } else {
                    sendBroadcast(new Intent(
                            Intent.ACTION_MEDIA_MOUNTED,
                            Uri.parse("file://"
                                    + Environment.getExternalStorageDirectory())));
                }
