Use SQlite in case of big data, for short information use preferences. — ravidl, Dec 18 '15 at 11:20
@ravidl for this question, its not needed to use `SQLite` as per my knowledge. — Nigam Patro, Dec 18 '15 at 11:24
@Nigam If he is fetching big data from web service then (as per my knowledge) keeping big data in shared preferences is not a good idea, that will take large cache memory. — ravidl, Dec 18 '15 at 11:35
@ravidl Yes you are right, but also with that using `SharedPreference` for storing login status is better. Because it will be faster. — Nigam Patro, Dec 18 '15 at 11:38
@NigamPatro that I mentioned already in the comment, for short information as like user preferences, conditional checks which are needed all time in hte app coulb be stored shared preferences. — ravidl, Dec 18 '15 at 11:41

{
Go to Main 
}else

Go to Login
}

Use SharedPreference which will store a boolean variable as isUserLoggedIn if user has logged in then it will store true otherwise false and then check the value of SharedPreference at splash screen.

You can use SharedPreference for achieving this. You need to implement the logic in your SplashActivity. You need to check whether already logged in or not using the value stored in shared preference and show next activity based on that.

In your SplashActivity (Where you launch the login activity), add the logic like:

// Retrieving your app specific preference
String sharedPrefId     = "MyAppPreference";
SharedPreferences prefs = getSharedPreferences(sharedPrefId, 0);

boolean isLoggedIn      = prefs.getBoolean("isLoggedIn", false);
if(isLoggedIn)
{ 
    // Show Main Activity
}
else
{
    // Show Login activity
}

And in your LoginActivity, after successful login set the value to true:

prefs.edit().putBoolean("isLoggedIn", true).commit();

Not Working :(.....I am editing My Question .. putting code inside that See it... – Atif Patel Dec 19 '15 at 04:28
@AtifPatel: Since you are using global shared preference and not your app specific one, you need to replace : `String sharedPrefId = "MyAppPreference"; SharedPreferences prefs = getSharedPreferences(sharedPrefId, 0);` with `SharedPreferences prefs = PreferenceManager .getDefaultSharedPreferences(Splash.this);` – Midhun MP Dec 19 '15 at 09:45
Salute you sir Thanks again You save my so much work and time – Atif Patel Dec 21 '15 at 05:06
help.......@Mithun Sir ... i wanna set Logout on HomePage ....How does it possible to Logout from global Shared Preference ...... – Atif Patel Dec 23 '15 at 05:23
@AtifPatel: You can clear the preference using `prefs.edit().remove("isLoggedIn").commit();` – Midhun MP Dec 23 '15 at 05:30
Thank you Sir ... Its Working i got ans – Atif Patel Dec 23 '15 at 11:37
