Joda-Time

Best way is to use Joda-Time, the highly successful open-source library you would add to your project.

String date1 = "2015-11-11";
String date2 = "2013-11-11";
DateTimeFormatter formatter = new DateTimeFormat.forPattern("yyyy-MM-dd");
DateTime d1 = formatter.parseDateTime(date1);
DateTime d2 = formatter.parseDateTime(date2);
long diffInMillis = d2.getMillis() - d1.getMillis();

Duration duration = new Duration(d1, d2);
int days = duration.getStandardDays();
int hours = duration.getStandardHours();
int minutes = duration.getStandardMinutes();

If you're using Android Studio, very easy to add joda-time. In your build.gradle (app):

dependencies {
  compile 'joda-time:joda-time:2.4'
  compile 'joda-time:joda-time:2.4'
  compile 'joda-time:joda-time:2.2'
}
