Question

I have Written the code to store the bitmap Image in sdcard But I want to store it along with the date time stamp .How to do it ?

bmp = processFrame(mCamera);
                String i1=bmp.toString();
                String root = Environment.getExternalStorageDirectory().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);
                           bmp.compress(Bitmap.CompressFormat.JPEG, 90, out);
                           out.flush();
                           out.close();

                    } catch (Exception e) {
                           e.printStackTrace();
                    }

use this

String fname = "Image-"+ n +System.currentTimeMillis() +".jpg";

instead of

String fname = "Image-"+ n +".jpg";

try this :

String getCurrentDate() {
        Calendar c = Calendar.getInstance();
        String Month = "";
        switch (c.get(Calendar.MONTH)) {
        case 0:
              Month = "Jan";
              break;
        case 1:
              Month = "Feb";
              break;
        case 2:
              Month = "Mar";
              break;
        case 3:
              Month = "Apr";
              break;
        case 4:
              Month = "May";
              break;
        case 5:
              Month = "June";
              break;
        case 6:
              Month = "July";
              break;
        case 7:
              Month = "Aug";
              break;
        case 8:
              Month = "Sep";
              break;
        case 9:
              Month = "Oct";
              break;
        case 10:
              Month = "Nov";
              break;
        case 11:
              Month = "Dec";
              break;
        default:
              break;
        }
        int ampm = c.get(Calendar.AM_PM);
        String amorpm = "";
        if (ampm == 1) {
              amorpm = "PM";
        } else {
              amorpm = "AM";
        }
        String date = c.get(Calendar.DAY_OF_MONTH) + "/" + Month + "/"
                    + c.get(Calendar.YEAR) + " " + c.get(Calendar.HOUR) + ":"
                    + c.get(Calendar.MINUTE) + " " + amorpm;
        // int Day = c.get(Calendar.DAY_OF_MONTH);
        // int month = c.get(Calendar.MONTH);
        return date;
  }

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); String dateTime = sdf.format(Calendar.getInstance().getTime()); with this code I am getting date time But how to store it to image – user1522869 Sep 10 '12 at 08:03
instead of String fname = "Image-"+ n +System.currentTimeMillis() +".jpg"; use String fname = "Image-"+ n +getCurrentDate() +".jpg"; – G_S Sep 10 '12 at 08:03

are you getting any warning in the logcat? – G_S Sep 10 '12 at 08:12
Well i think i got the issue. File names should not have a <> or / or * and so on check the name of the file that you are getting – G_S Sep 10 '12 at 08:14
I am nor getting what you want to say – user1522869 Sep 10 '12 at 08:17
check heading Forbidden characters in filenames in http://cygwin.com/cygwin-ug-net/using-specialnames.html – G_S Sep 10 '12 at 08:20
Then can we write it on image – user1522869 Sep 10 '12 at 08:25
2012-09-10 13:56:54 I am getting date time like this – user1522869 Sep 10 '12 at 08:29
yes you can. try using this http://stackoverflow.com/questions/5002722/draw-text-on-top-of-bitmap-failed – G_S Sep 10 '12 at 08:30
You cant use a : in file names. That's the issue – G_S Sep 10 '12 at 08:30
can we parse it to 2012-09-10 13 -56-54 how to do it – user1522869 Sep 10 '12 at 08:32
what do you want to parse it to? – G_S Sep 10 '12 at 08:33
hey use the code that i posted if you want the format you want. – G_S Sep 10 '12 at 08:43
Calendar c = Calendar.getInstance(); String date = c.get(Calendar.DAY_OF_MONTH) + "/" + c.get(Calendar.MONTH) + "/" + c.get(Calendar.YEAR) + " " + c.get(Calendar.HOUR) + "-" + c.get(Calendar.MINUTE) + " " ; System.out.println(" "+date); – G_S Sep 10 '12 at 08:47
