I am getting the current date (in format 12/31/1999 i.e. mm/dd/yyyy) as using the below code:

Textview txtViewData;
txtViewDate.setText(\"Today is \" +

I found a very easy way to do this and it's what I'm using in my app.

Let's say you have the dates in Time objects (or whatever, we just need the milliseconds):

Time date1 = initializeDate1(); //get the date from somewhere
Time date2 = initializeDate2(); //get the date from somewhere

long millis1 = date1.toMillis(true);
long millis2 = date2.toMillis(true);

long difference = millis2 - millis1 ;

//now get the days from the difference and that's it
long days = TimeUnit.MILLISECONDS.toDays(difference);

//now you can do something like
if(days == 7)
{
    //do whatever when there's a week of difference
}

if(days >= 30)
{
    //do whatever when it's been a month or more
}
