// This is my code

Are you sure that you have already checked if the user has granted permission to external storage or not?

Then try this one (your code does not work for 20 API levels and above):

private void saveImageToExternalStorage(Bitmap finalBitmap) {
String root = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES).toString();
File myDir = new File(root + "/saved_images");
myDir.mkdirs();
Random generator = new Random();
int n = 10000;
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, 90, out);
    out.flush();
    out.close();
}
catch (Exception e) {
    e.printStackTrace();
}


// Tell the media scanner about the new file so that it is
// immediately available to the user.
MediaScannerConnection.scanFile(this, new String[] { file.toString() }, null,
        new MediaScannerConnection.OnScanCompletedListener() {
            public void onScanCompleted(String path, Uri uri) {
                Log.i("ExternalStorage", "Scanned " + path + ":");
                Log.i("ExternalStorage", "-> uri=" + uri);
            }
});

}
