Twitter Digits check if the authentication was already made

Question

I managed to integrate twitter digits and the authentication is working, but I want to check if the user already added his number and code.

For now I only have the authentication part:

    final TwitterAuthConfig authConfig = new TwitterAuthConfig(TWITTER_KEY, TWITTER_SECRET);
    Fabric.with(this, new Crashlytics(), new Twitter(authConfig));

And the button event:

  digitsButton = (DigitsAuthButton) findViewById(R.id.auth_button);
    digitsButton.setCallback(new AuthCallback() {
        @Override
        public void success(DigitsSession session,
                            String phoneNumber) {
            // Do something with the session
            Toast.makeText(WelcomeActivity.this,"Registration Successful",Toast.LENGTH_SHORT).show();
        }

        @Override
        public void failure(DigitsException exception) {
            // Do something on failure
            Toast.makeText(WelcomeActivity.this,"Registration Failed",Toast.LENGTH_SHORT).show();
        }
    });

How can I check if the user already made these steps?

Answer 1

You can save the fact that an authentication was successful by storing the data somewhere. Storage Options

Using SharedPreferences, to check if an authentication was successful you would use isAuthenticated below:

SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);
boolean isAuthenticated = settings.getBoolean("ALREADY_AUTHENTICATED", false);

And to set that an authentication was successful (true), you could put this in the callback's success method

// We need an Editor object to make preference changes.
// All objects are from android.context.Context
SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);
SharedPreferences.Editor editor = settings.edit();
editor.putBoolean("ALREADY_AUTHENTICATED", true /** or false */);

// Commit the edits!
editor.commit();
