You can do following   private Date getMeYesterday         return new Date System currentTimeMillis  -24 60 60 1000       Note  if you want further backward date multiply number of day with 24 60 60 1000 for example   private Date getPreviousWeekDate         return new Date System currentTimeMillis  -7 24 60 60 1000       Similarly  you can get future date by adding the value to System currentTimeMillis    for example   private Date getMeTomorrow         return new Date System currentTimeMillis   24 60 60 1000

There is no direct function to get yesterday s date   To get yesterday s date  you need to use Calendar by subtracting -1

changed from your code    private String toDate long timestamp        Date date   new Date  timestamp   1000 -  24   60   60   1000      return new SimpleDateFormat  yyyy-MM-dd   format date  toString         but you do better using calendar
