Question

I have this code:

public class Register extends Activity {

    private LinearLayout layout;
    private TextView debug;
    public static final String USER_CONFIG = "UserConfigs";

    @Override
    public void onCreate (Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.register);

        SharedPreferences settings = getSharedPreferences(USER_CONFIG, MODE_PRIVATE);
        boolean registered = settings.getBoolean("registered", false);

        layout = (LinearLayout) findViewById(R.id.layoutRegister);

        if (!registered) {
            debug = new TextView(this);
            debug.setText("You have to register");
            layout.addView (debug);

            //TO DO user registration

            settings.edit().putBoolean("registered", true);
            settings.edit().commit(); 
        } else {
            debug = new TextView(this);
            debug.setText("You have already registered");
            layout.addView (debug);
            //TO DO skip to next screen
        }
    }
}

But I’m always getting registered as “false” when I restart my app. I have tried to commit it on the onStop() as well and got the same result. I have seen other topics with this problem here but none of them had the same problem as I do.

Any ideas?

You can’t do this:

settings.edit().putBoolean("registered", true);
settings.edit().commit(); 

You need to get the editor object, then make the changes:

Editor editor = settings.edit();
editor.putBoolean(...);
editor.commit();
