How to format correctly according to the device configuration date and time when having a year, month, day, hour and minute?
Use the standard Java DateFormat class.
For example to display the current date and time do the following:
Date date = new Date(location.getTime());
DateFormat dateFormat = android.text.format.DateFormat.getDateFormat(getApplicationContext());
mTimeText.setText("Time: " + dateFormat.format(date));
You can initialise a Date object with your own values, however you should be aware that the constructors have been deprecated and you should really be using a Java Calendar object.
