Android: Images saved by my app do not show in gallery -- even after reboot

I create and save image in my Android app:

File dir = new File(Environment.getExternalStorageDirectory(), ".myappname/saved");
File imageFile = new File(dir, "IMG" + random() + ".jpg");
FileOutputStream out = new FileOutputStream(imageFile);
bi.compress(Bitmap.CompressFormat.JPEG, 100, out);

The images do not show up in the gallery -- even after reboots.

UPDATE: I only show part of the code! I also corrected the typos I introduced when writing the StackOverFlow message. The images save fine -- and I can view them -- they just don't show in Gallery. I just removed the dot from ".myappname" -- no the gallery shows the images. Strange. As I say below other apps save images in dot-folders and they show in gallery :(

Write this Function in your Activity...

private void scanFile(String path) {

        MediaScannerConnection.scanFile(MainActivity.this,
                new String[] { path }, null,
                new MediaScannerConnection.OnScanCompletedListener() {

                    public void onScanCompleted(String path, Uri uri) {
                        Log.i("TAG", "Finished scanning " + path);
                    }
                });
    }

and then call this function where you save your image

scanFile(yourFile.getAbsolutePath());

your current problem is . appearing in the file path which makes it hidden but in some cases,
gallery does not populate images from private space
so use code 



sendBroadcast(new Intent(
Intent.ACTION_MEDIA_MOUNTED,
            Uri.parse("file://" + Environment.getExternalStorageDirectory())));
in your onDestroy() method`.

Save file on SDCARD/"some folde r" it will reflect in gallery,Gallery app doesn't shows images from private space. change below line of your code

 File fwdir = new File(Environment.getExternalStorageDirectory(), "myappname/saved");

Edit :- removed . from the directory name. as it is gonna be hidden folder.

You are creating a hidden folder by prefixing the folder name with a "." (period) the Media scanner will ignore this. At least that's the behavior I see when doing the same manually I have not tried it through code. Look at option 2 in this post http://www.makeuseof.com/tag/hide-private-picture-folders-gallery-android/
