Question

in my app next to the splash screen i need to show an activity called Tips Page. This activity to be shown once in a day. When the user opens the app again within 24 hrs it should not be shown.

First i tried to show based on the current date, when the first the activity shown i will store the current date in shared preference and next time when the app gets opened i will check whether the current date and date in shared preference are equal or not. If equal i will not show the activity if not i will show the activity.

But here there is a logic mistake, if the user opens the app first in midnight of 11 PM in a date, and again opens the app after t hour the Tips activity will be shown, but i need to show it after 24 hrs, how can it be done. pls help me in this ligic

I think you need such a flow, see this the implementation of Jason Hessley’s Answer

 SharedPreferences settings = getSharedPreferences("Preferences",
            MODE_PRIVATE);

    long timeFromPrefs = settings.getLong("time", System.currentTimeMillis());
    final long TIME_DIFF = 24*60*60*1000; 


    if ((System.currentTimeMillis()-timeFromPrefs)>TIME_DIFF) {
        // show Activity...........
        Editor editor = settings.edit();
        editor.putLong("time", System.currentTimeMillis());
        editor.commit();

    }
