You can calculate the difference in time in miliseconds using this method and get the outputs in seconds, minutes, hours, days, months and years.

You can download class from here: DateTimeDifference GitHub Link

Simple to use

long currentTime = System.currentTimeMillis();
long previousTime = (System.currentTimeMillis() - 864000000); //10 days ago

Log.d("DateTime: ", "Difference With Second: " + AppUtility.DateTimeDifference(currentTime, previousTime, AppUtility.TimeDifference.SECOND));
Log.d("DateTime: ", "Difference With Minute: " + AppUtility.DateTimeDifference(currentTime, previousTime, AppUtility.TimeDifference.MINUTE));

You can compare the example below

if(AppUtility.DateTimeDifference(currentTime, previousTime, AppUtility.TimeDifference.MINUTE) > 100){
    Log.d("DateTime: ", "There are more than 100 minutes difference between two dates.");
}else{
    Log.d("DateTime: ", "There are no more than 100 minutes difference between two dates.");
}

You can generalize this into a function that lets you choose the output format  private String substractDates Date date1  Date date2  SimpleDateFormat format        long restDatesinMillis   date1 getTime  -date2 getTime        Date restdate   new Date restDatesinMillis        return format format restdate       Now is a simple function call like this  difference in hours  minutes and seconds   SimpleDateFormat formater   new SimpleDateFormat  yyyy-MM-dd HH mm ss     try       Date date1   formater parse dateEnd       Date date2   formater parse dateInit        String result   substractDates date1  date2  new SimpleDateFormat  HH mm ss          txtTime setText result     catch  ParseException e        e printStackTrace

Here is the modern answer  It   s good for anyone who either uses Java 8 or later  which doesn   t go for most Android phones yet  or is happy with an external library       String date1    20170717141000       String date2    20170719175500        DateTimeFormatter formatter   DateTimeFormatter ofPattern  yyyyMMddHHmmss        Duration diff   Duration between LocalDateTime parse date1  formatter                                         LocalDateTime parse date2  formatter         if  diff isZero              System out println  0m          else           long days   diff toDays            if  days    0                System out print      days    d                 diff   diff minusDays days                     long hours   diff toHours            if  hours    0                System out print      hours    h                 diff   diff minusHours hours                     long minutes   diff toMinutes            if  minutes    0                System out print      minutes    m                 diff   diff minusMinutes minutes                     long seconds   diff getSeconds            if  seconds    0                System out print      seconds    s                       System out println            This prints  2d 3h 45m    In my own opinion the advantage is not so much that it is shorter  it   s not much   but leaving the calculations to an standard library is less errorprone and gives you clearer code  These are great advantages  The reader is not burdened with recognizing constants like 24  60 and 1000 and verifying that they are used correctly   I am using the modern Java date  amp  time API  described in JSR-310 and also known under this name   To use this on Android under API level 26  get the ThreeTenABP  see this question  How to use ThreeTenABP in Android Project  To use it with other Java 6 or 7  get ThreeTen Backport  With Java 8 and later it is built-in   With Java 9 it will be still a bit easier since the Duration class is extended with methods to give you the days part  hours part  minutes part and seconds part separately so you don   t need the subtractions  See an example in my answer here

When you use Date   to calculate the difference in hours is necessary configure the SimpleDateFormat   in UTC otherwise you get one hour error due to Daylight SavingTime
