android sharedpreferences return with null

I am developing a "book an appointment" application for android mobiles which have Users I have a User class for it, with properties userID, email, name, password and phonenumber. And I have different activities which are using it. I want to store those data in the Sharedpreference. But something goes wrong, in the storeUserData() in debug mode, there are all the data in the user. And in the setUserLoggedIn() I added to the same preference a boolean, but somehow it returns false. And the end the user = null.... But I call setUserLoggedIn like this: 

private void logUserIn(User returnedUser) {

    userLocalStore.storeUserData(returnedUser);
    userLocalStore.setUserLoggedIn(true);
}

So I give it a true value. What have I missed? How should I get those data from storeUserData? Here's the code:

public void storeUserData(User user){
    SharedPreferences.Editor userLocalDatabaseEditor = userLocalDatabase.edit();
    userLocalDatabaseEditor.putInt("userID", user.userID);
    userLocalDatabaseEditor.putString("name", user.name);
    userLocalDatabaseEditor.putString("email", user.email);
    userLocalDatabaseEditor.putString("password", user.password);
    userLocalDatabaseEditor.putString("phonenumber", user.phonenumber);
    userLocalDatabaseEditor.commit(); //May I should use apply() ?
}

public void setUserLoggedIn(boolean loggedIn){
    SharedPreferences.Editor userLocalDatabaseEditor = userLocalDatabase.edit();
    userLocalDatabase.getString("name", "");
    userLocalDatabaseEditor.putBoolean("LoggedIn", loggedIn);
    userLocalDatabaseEditor.commit();
}

public User getLoggedInUser(){

    if(userLocalDatabase.getBoolean("loggedIn", false) == false){
        return null;
    }

    int userID = userLocalDatabase.getInt("userID", -1);
    String name = userLocalDatabase.getString("name", "");
    String email = userLocalDatabase.getString("email", "");
    String password = userLocalDatabase.getString("password", "");
    String phonenumber = userLocalDatabase.getString("phonenumber", "");
    //String name, String username, String password, String email, String phonenumber
    User user = new User(userID, name, email, password, phonenumber);

    return user;
}

You are getting wrong key here. It must be LoggedIn instead of loggedIn. So your code should be:

public User getLoggedInUser(){
    if(userLocalDatabase.getBoolean("LoggedIn", false) == false){
        return null;
    }
}
