Question

How can i get email address of a user via twitter API? I\'m using Twitter4j for Sign in with twitter

Answer 1

first of all make sure you activated Request email addresses from users in your twitter app Permissions section

then follow Twitter Documentation steps:

1. Installation process: which simply imports the sdk package of twitter

and i'm using only the core package

compile 'com.twitter.sdk.android:twitter-core:3.1.1'

Initialize Twitter Kit on your Activity onCreate method

Twitter.initialize(this);

Add your App id and secret to strings.xml file

XXXXXXXXXXX
XXXXXXXXXXX

2. Add the Button:

HINT: you can use a custom button just follow this simple answer

private TwitterLoginButton twitterBtn;

...

twitterBtn = (TwitterLoginButton) findViewById(R.id.twitter_connect);
twitterBtn.setCallback(new Callback() {
    @Override
    public void success(Result result) {
        // Do something with result, which provides a TwitterSession for making API calls
        // which is do the callback from twitter to get the Email
        TwitterSession session = TwitterCore.getInstance().getSessionManager().getActiveSession();
        TwitterAuthToken authToken = session.getAuthToken();
        String token = authToken.token;
        String secret = authToken.secret;

        TwitterAuthClient authClient = new TwitterAuthClient();
        authClient.requestEmail(session, new Callback() {
            @Override
            public void success(Result result) {
                // Do something with the result, which provides the email address
                // the email is saved in the result variable 'result.data'
                Toast.makeText(getBaseContext(), "Email" + result.data, Toast.LENGTH_LONG).show();
            }

            @Override
            public void failure(TwitterException exception) {
                // Do something on failure
            }
        });
    }

    @Override
    public void failure(TwitterException exception) {
        // Do something on failure
    }
});

Next, pass the result of the authentication Activity back to the button:

// Pass the activity result to the login button.
twitterBtn.onActivityResult(requestCode, resultCode, data);

like so:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    // Pass the activity result to the login button.
    twitterBtn.onActivityResult(requestCode, resultCode, data);
}
