What is the best way and how to convert this string "2015-07-18T13:32:56.971-0400" to date and converting to user's phone's local timezone in android?

I listed the duplicate link because you're asking how to parse a date string. That has been answered a gazillion times.

The other link shows that the user's phone's local timezone in android is the default timezone of the JVM, so you don't have to do any conversion.

To see for yourself, run the following code in any JVM (Android, PC, Mac, Linux, ...):

String input = "2015-07-18T13:32:56.971-0400";

Date date = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSZ").parse(input);
String output = new SimpleDateFormat("MM/dd/yyyy hh:mm:ss.SSS a").format(date);
System.out.println(input + "  ->  " + output);

If you're in Los Angeles, CA, USA, you get this:

2015-07-18T13:32:56.971-0400  ->  07/18/2015 10:32:56.971 AM

Note that 13:32 was adjusted to 10:32 AM (10:32).

Just use these to get the time and date 

public String getCurrentDate(){
    Time dtNow = new Time();
    dtNow.setToNow();
    return dtNow.format("%Y.%m.%d %H:%M");    // YYYYMMDDTHHMMSS
}

public String getCurrentTime(){
    Time dtNow = new Time();
    dtNow.setToNow();
    return dtNow.format("%H:%M");    // YYYYMMDDTHHMMSS
}

the first function will return time and the second function returns date
