Can't see the bitmap I saved to new directory

I was looking for a way to save a bitmap to a folder (with my app's name), in such a way the default gallery will recognize it.

So I managed to save the image, but I can't see it either from the gallery or my PC (using explorer)

this is my code: 

 // Save bitmap to internal memory
private void savePhoto(Bitmap bmp){
    String appName = "myApp";

    String file_path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES)+ File.separator + appName;
    File dir = new File(file_path);

    if(!dir.exists())
        dir.mkdirs();   

    // Image file
    File file = new File(dir, "IMG" + "_" +     System.currentTimeMillis() + ".jpg");
    FileOutputStream out = null;

    try
    {
     out = new FileOutputStream(file);
     bmp.compress(Bitmap.CompressFormat.JPEG, 100, out);
     out.flush();
     out.close();

     out = null;
    } catch (Exception e)
    {
        e.printStackTrace();
    }

}

I can see it using some File Manager installed on my galaxy, but it doesn't help a lot. I know I should inform the gallery using a media scanner (which is another bridge I need to cross) but may someone help me understand way I can't even find the file..should I change its visibility somehow?

and one more thing: I read at another question regarding the issue, that I should add metadata to the image/folder so that the gallery would show it. Is it necessary?

Many thanks!!!

Apparently it did have something to do with the media scanner, I added this line 

MediaScannerConnection.scanFile(this, new String[] { file.getAbsolutePath() }, null, null);

and now it works.

from the documentation:

MediaScannerConnection provides a way for applications to pass a newly created or downloaded media file to the media scanner service. The media scanner service will read metadata from the file and add the file to the media content provider.
