(1) Yes, it;' absolutely fine.... I am also using that
(2) You can do that like this:
user_data_in_shared = mPrefs.getString("Your_Key", "NOT_EXIST");
If you have already defined your value for the key "Your_key",
than it will return the value. If no value is set on key "Your_Key",
then it will simple return the defalut value (whatever you set as
second parameter. here "NOT_EXIST")
(3) Simply replace the value with null.
