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;
}
