How to get the value store in SharedPreferences

Question

I am storing userId at the time of registration in SharedPreferencesand. Now I want to access the SharedPreferences stored UserId value. Till now I tried this code:

prefrence = PreferenceManager.getDefaultSharedPreferences(this);
edit3 = prefrence.edit();
edit3.putInt("user_id", userid);
Log.e("Commit", "SharedPreferences");
edit3.commit();

And on the next activity I am using this for access:

prefr = PreferenceManager.getDefaultSharedPreferences(this);

value = prefr.getInt("user_id", "");

How do I do this?

On a side note, `Log.e()` should be used to log errors, not generic debug messages like committing preference value. You'd better use `Log.d()` instead. — keaukraine, Jan 03 '14 at 08:09
@keaukraine yeh..but I personally like Log.e() as it shows message in RED color. — Ketan Ahir, Jan 03 '14 at 08:11

You PUT in an INT and GET a STRING... Maybe that's causing a type cast error.

I see you changed your code, to get an int... the WRONG WAY!

You are doing so:

value = prefr.getInt("user_id", "");

Instead you should do so:

value = prefr.getInt("user_id", 0);

(You can't assign "" to an int.)

The above is valid if user_id is an int. If user_id is a string, then you should do a putString and a getString. Like:

edit3.putString("user_id", userid);

And then

value = prefr.getString("user_id", "");

So you grant the necessary type consistency.

Yep, `prefr.getInt("user_id", "")` shouldn't compile. There's no such overloaded `getInt()` method. – keaukraine Jan 03 '14 at 08:13

Try changing

prefr.getString("user_id", "");

to

prefr.getInt("user_id", 0);
