changing the filter to remain active if do same search

gistfile1.txt

1. In FlightSearchFormActivity, line FilterActivity.resetFilter() replaced with:
            if (mFlightSearch == null || !isSameFlightSearch(mFlightSearch, mFile)) {
                    FiltersActivity.resetFilters();
            }
2. isSameFlightSearch(FlightSearch flightSearch, File file) is defined in Utils file. I was trying to make this method
            do less calculation in UI thread, so another way is create an AsyncTask, as we did in SaveFlightSearchTask.java
            http://stackoverflow.com/questions/12575068/how-to-get-the-result-of-onpostexecute-to-main-activity-because-asynctask-is-a

   public static boolean isSameFlightSearch(FlightSearch flightSearch, File file) {
        if (flightSearch.isValid() && file != null) {
            return flightSearch.equals(flightSearchFromFile(file.getPath()));
        }
        return false;
    }
    
3. In FlightSearchFormActivity changed the local variable file into private member variable, named mFile.
4. Added unit test in Utils
   testIsSameFlightSearchReturnsTrueIfSameFlightSearchIsPerformed()
   testIsSameFlightSearchReturnsFalseIfNewFlightSearchIsPerformed()
   testIsSameFlightSearchReturnsFalseIfFlightSearchIsNotValid()
   testIsSameFlightSearchReturnsFalseIfDifferentFilePath()
   
5. Added integration test in FlightSearchFormActivityTest
   testToVerifyPerformingSameSearchWillKeepAllSelectedFilters()
   testToVerifyPerformingNewSearchWillResetAllFilters()
   

You don't need to read from file and add any async task. Just have old flight search object in memory and compare it with new flight search. No need to add extra util method. Just oldFlightSearch.equals(newFlightSearch) should do it.

Yeah! That's much better! Thanks!
