Comparing Current Time In Milliseconds To Time Saved In Shared Preferences

I've shared my current time in sharedPreferences using the following method: Date date = new Date(System.currentTimeMillis()); SharedPreferences pref = getApplicationContext().get

Solution 1:

1st of all, on this line you should change to:

editor.putLong("smstimestamp", System.currentTimeMillis());

there's no need to create a date and then get the millis again.

now to compare it:

//             milli min  hour  day 30day
long days_30 = 1000 * 60 * 60 * 24 * 30;
SharedPreferences pref = getApplicationContext().getSharedPreferences("DataCountService", 0);
long oldTime = pref.getLong("smstimestamp");
if(System.currentTimeMillis() - oldTime > days_30){
      // here, more than 30 days
}
