Twitter APIs

Creating login with twitter button and attach a callback to it

1. Inside your layout, add a Login button with the following code:

    <com.twitter.sdk.android.core.identity.TwitterLoginButton
        android:id="@+id/twitter_login_button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"/>

2. In the Activity or Fragment that displays the button, you need to create and attach a Callback to the Login Buttonas the following:

    import com.twitter.sdk.android.core.Callback;
    import com.twitter.sdk.android.core.Result;
    import com.twitter.sdk.android.core.TwitterException;
    import com.twitter.sdk.android.core.TwitterSession;
    import com.twitter.sdk.android.core.identity.TwitterLoginButton;
    ...
   
    loginButton = (TwitterLoginButton) findViewById(R.id.login_button);
    loginButton.setCallback(new Callback<TwitterSession>() {
        @Override
        public void success(Result<TwitterSession> result) {
            Log.d(TAG, "userName: " + session.getUserName());
            Log.d(TAG, "userId: " + session.getUserId());
            Log.d(TAG, "authToken: " + session.getAuthToken());
            Log.d(TAG, "id: " + session.getId());
            Log.d(TAG, "authToken: " + session.getAuthToken().token);
            Log.d(TAG, "authSecret: " + session.getAuthToken().secret);
        }
   
        @Override
        public void failure(TwitterException exception) {
            // Do something on failure
        }
    });

3. Pass the result of the authentication Activity back to the button:

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        // Make sure that the loginButton hears the result from any
        // Activity that it triggered.
        loginButton.onActivityResult(requestCode, resultCode, data);
    }

   Note, If using the TwitterLoginButton in a Fragment, use the following steps instead:

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
   
        // Pass the activity result to the fragment, which will then pass the result to the login
        // button.
        Fragment fragment = getFragmentManager().findFragmentById(R.id.your_fragment_id);
        if (fragment != null) {
            fragment.onActivityResult(requestCode, resultCode, data);
        }
    }

4. Add the following lines to your build.gradle dependencies:

    apply plugin: 'io.fabric'
   
    repositories {
        maven { url 'https://maven.fabric.io/public' }
    }
   
    compile('com.twitter.sdk.android:twitter:1.14.1@aar') {
        transitive = true;
    }
