Use SimpleDateFormat for Android N and above. Use the calendar for earlier versions for example:

if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
        fileName = new SimpleDateFormat("yyyy-MM-dd-hh:mm:ss").format(new Date());
        Log.i("fileName before",fileName);
    }else{
        Calendar cal = Calendar.getInstance();
        cal.add(Calendar.MONTH,1);
        String zamanl =""+cal.get(Calendar.YEAR)+"-"+cal.get(Calendar.MONTH)+"-"+cal.get(Calendar.DAY_OF_MONTH)+"-"+cal.get(Calendar.HOUR_OF_DAY)+":"+cal.get(Calendar.MINUTE)+":"+cal.get(Calendar.SECOND);

        fileName= zamanl;
        Log.i("fileName after",fileName);
    }

Output:
fileName before: 2019-04-12-07:14:47 // use SimpleDateFormat
fileName after: 2019-4-12-7:13:12 // use Calender

I ve been looking for an efficient way to do this for quite some time and the best I ve found is   DateFormat getDateInstance DateFormat SHORT  format new Date millis      Advantages    It s localized Been in Android since API 1 Very simple   Disadvantages    Limited format options   FYI   SHORT is only a 2 digit year  You burn a Date object every time   I ve looked at source for the other options and this is a fairly minor compared to their overhead    You can cache the java text DateFormat object  but it s not threadsafe   This is OK if you are using it on the UI thread
