try like this

    Bitmap bm = BitmapFactory.decodeResource(getResources(), to); 
    File myDir = new File("/mnt/sdcard/");    
    String fname = "filename"+".png";
    File file = new File (myDir,fname);
    if (file.exists ()) file.delete (); 
    try {
          FileOutputStream out = new FileOutputStream(file);
           bitmap.compress(Bitmap.CompressFormat.PNG, 90, out);
          out.flush();
           out.close();
       } catch (Exception e) {
           e.printStackTrace();
      }

Superb!! It works! But the only problem is that photos are saved in camera pictures,all picture, camera media all.. – 9477 Oct 07 '13 at 07:29
you can give the desired path inside the file path **File myDir = new File("/mnt/sdcard/");** – Boopathi Oct 07 '13 at 10:36
@user2789816 You could better use **Environment.getExternalStorage()** to get the exact sdcard path/location. Because in some mobiles the mounting location might be changed. – Ajeesh Oct 07 '13 at 10:40
It gives me a problem. If i use this code than photo is not saving in gallery. If saving than only 1 photo can be saved and when i open it photo gets changed. :( – 9477 Oct 08 '13 at 05:55
@user2789816 you should note the line **if (file.exists ()) file.delete ();** it will remove if the same file name exits – Boopathi Oct 08 '13 at 12:25
