Anyway, java have problem with Date and Time.

You should use Joda Time It's date and time library to replace JDK date handling

Download: http://mvnrepository.com/artifact/joda-time/joda-time/2.3

try before() and after() methods of Calender

public boolean isTimeWithinInterval(String lwrLimit, String uprLimit, String time){

    // Time 1 in string - Lower limit
    Date time_1 = new SimpleDateFormat("HH:mm:ss").parse(lwrLimit);
    Calendar calendar_1 = Calendar.getInstance();
    calendar_1.setTime(time_1);

    // Time 2 in string - Upper limit
    Date time_2 = new SimpleDateFormat("HH:mm:ss").parse(uprLimit);
    Calendar calendar_2 = Calendar.getInstance();
    calendar_2.setTime(time_2);

    // Time 3 in String - to be checked
    Date d = new SimpleDateFormat("HH:mm:ss").parse(time);
    Calendar calendar_3 = Calendar.getInstance();
    calendar_3.setTime(d);

    Date x = calendar_3.getTime();
    if (x.after(calendar_1.getTime()) && x.before(calendar_2.getTime())) {
        //checkes whether the current time is between two times
        Log.d(TAG,true+"");
        return true;
    } 

    return false;
}

Update :

 boolean timeChk = isTimeWithinInterval(time1, time2, time3);

 if(timeChk){
   // Success code
   tvTime.setText(" " + time3);
 }
 else{
   // Failure code

 }

You should really try to use Calendar class that is WAY easier and that has that feature with Calendar.before(calendar).
