Question

This is in my onCreate:

sharedPrefs = PreferenceManager.getDefaultSharedPreferences(this);

sharedPrefs being an uninitialized SharedPreferences in the class.

Later, I do this:

sharedPrefs.edit().putString("token", token);
Log.d("asdf", "token is " + token);
Log.d("asdf", "reading prefs: " + sharedPrefs.getString("token", null));

And the log output is as follows:

token is ABC123
reading prefs: null

So token (a string) is definitely getting set correctly. But for some reason.. it just won’t save/read in the sharedPreferences.

Any ideas? I’ll post the full code if you guys want, but I doubt it’ll help.

Answer 1

After the put() method, you should implement sharedPrefs.edit().commit() to commit the data into the sharedpreference.

sharedPrefs.edit().putString("token", token)
                .commit();
