Question

I have this simple piece of code:

        SharedPreferences settings = getSharedPreferences(Constants.USER_DETAILS, 0);
        SharedPreferences.Editor editor = settings.edit();

        //editor.putLong(Constants.USER_DETAILS_SIGNEDINON, registerResponse.getSignedInOn()); // signed in on

        editor.putLong(Constants.USER_DETAILS_SIGNEDINON, 1); // signed in on
        long test = settings.getLong(Constants.USER_DETAILS_SIGNEDINON, 2);

        if (settings.edit().commit()) {
            System.out.print("ok");
        } else {
            System.out.print("not ok");
        }

as you can see I have been playing around to understand what is going on.

So, I have checked the /data/data/… and the preferences file is indeed created but is empty (just the Map tag)

The test long variable returns 2, even if I set it to 1 the line before.
The commit returns true.

Am I missing something?

I have set uses-permission android:name=android.permission.WRITE_EXTERNAL_STORAGE
though I believe this is only needed when I truly do external storage.

Regards.
David.

Try this piece of code.

    SharedPreferences settings = getSharedPreferences(Constants.USER_DETAILS, 0);
    SharedPreferences.Editor editor = settings.edit();

    //editor.putLong(Constants.USER_DETAILS_SIGNEDINON, registerResponse.getSignedInOn()); // signed in on

    editor.putLong(Constants.USER_DETAILS_SIGNEDINON, 1); // signed in on

    if (editor.commit()) {
        System.out.print("ok");
    } else {
        System.out.print("not ok");
    }
    long test = settings.getLong(Constants.USER_DETAILS_SIGNEDINON, 2);
