Android Twitter oAuth Connect Tutorial

Integrating twitter in your android application will make user easily login into your app using their twitter account which avoids filling a long registration forms. In this tutorial i explained how to integrate twitter in your android application using twitter oAuth procedure. This is very basic tutorial with simple login and updating twitter status message.

Download Code


Registering twitter app – getting Consumer Key & Consumer Secret

In order to implement twitter oAuth in your application you need twitter consumer key and consumer secret which are used to make twitter API calls. So register a new twitter application and get the keys. Check the following video about creating a twitter app

1. Go to https://dev.twitter.com/apps/new and register new application. Fill application name, description and website.
2. Give some dummy url in the callback url field to make the app as browser app. (If you leave it as blank it will act as Desktop app which won’t work in mobile device)

3. Under the settings tab upload icon and change the access type to Read and Write.

4. Copy Consumer Key & Consumer Secret key

Downloading twitter4j library

In this tutorial to integrate twitter i used one of the most popular libraries twitter4j. You can read their official documentation to know more about it.

1. Download & extract twitter4j library from twitter4j-android-2.2.6.zip (slimmed version for Android platform). Here is the direct link

Creating new Project

In this tutorial i explained basic twitter API calls login and updating status only. If you want to integrate more api calls like reading users tweet timeline, sending direct message etc., you need to include other required .jar files too. Read more Code Examples to get know the usage.

1. Create a new project in Eclipse File New ⇒ Android ⇒ Application Project and fill the required details.
After creating project open AndroidManifest.xml file and paste the following code. I added following code to manifest file

- INTERNET Permission
- ACCESS_NETWORK_STATE Permission
- and added an Intent Filter

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.androidhive.twitterconnect"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="15" />

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".MainActivity"
            android:label="@string/title_activity_main" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
            <intent-filter>
                <action android:name="android.intent.action.VIEW" />
                <category android:name="android.intent.category.DEFAULT" />
                <category android:name="android.intent.category.BROWSABLE" />
                <data android:scheme="oauth" android:host="t4jsample"/>
            </intent-filter>
        </activity>
    </application>
    
    <!-- Permission - Internet Connect -->
    <uses-permission android:name="android.permission.INTERNET" />
    
    <!-- Network State Permissions -->
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

</manifest>

2. Copy the required twitter4j .jar files into your project’s libs folder. In this tutorial i copied twitter4j-core-android-2.2.6 as it is the only required file in this tutorial.

android twitter4j jar files
android adding twitter4j jar files to project

3. Before getting into twitter integration i am including two quick class files to the project. Create a new class file called AlertDialogManager.java and paste the following code. This class file used to show alert dialog.

package com.androidhive.twitterconnect;

import android.app.AlertDialog;
import android.content.Context;
import android.content.DialogInterface;

public class AlertDialogManager {
	/**
	 * Function to display simple Alert Dialog
	 * @param context - application context
	 * @param title - alert dialog title
	 * @param message - alert message
	 * @param status - success/failure (used to set icon)
	 * 				 - pass null if you don't want icon
	 * */
	public void showAlertDialog(Context context, String title, String message,
			Boolean status) {
		AlertDialog alertDialog = new AlertDialog.Builder(context).create();

		// Setting Dialog Title
		alertDialog.setTitle(title);

		// Setting Dialog Message
		alertDialog.setMessage(message);

		if(status != null)
			// Setting alert dialog icon
			alertDialog.setIcon((status) ? R.drawable.success : R.drawable.fail);

		// Setting OK Button
		alertDialog.setButton("OK", new DialogInterface.OnClickListener() {
			public void onClick(DialogInterface dialog, int which) {
			}
		});

		// Showing Alert Message
		alertDialog.show();
	}
}

4. Create another class file named ConnectionDetector.java and paste the following code. This class is used to detect internet connection status.

package com.androidhive.twitterconnect;

import android.content.Context;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;
 
public class ConnectionDetector {
 
    private Context _context;
 
    public ConnectionDetector(Context context){
        this._context = context;
    }
 
    /**
     * Checking for all possible internet providers
     * **/
    public boolean isConnectingToInternet(){
        ConnectivityManager connectivity = (ConnectivityManager) _context.getSystemService(Context.CONNECTIVITY_SERVICE);
          if (connectivity != null)
          {
              NetworkInfo[] info = connectivity.getAllNetworkInfo();
              if (info != null)
                  for (int i = 0; i < info.length; i++)
                      if (info[i].getState() == NetworkInfo.State.CONNECTED)
                      {
                          return true;
                      }
 
          }
          return false;
    }
}

5. Open your activity_main.xml file and type the following code. In the following code i am placing login button, update status edittext and update status button. By default all the ui elements will be hidden except login button.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >
    
    <!-- Twitter Login Button -->
    <Button android:id="@+id/btnLoginTwitter"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="Login with Twitter"
        android:layout_marginLeft="10dip"
        android:layout_marginRight="10dip"
        android:layout_marginTop="30dip"/>
    
    <!-- user name label -->
    <TextView android:id="@+id/lblUserName"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:padding="10dip"
        android:layout_marginTop="30dip"/>

    <!-- label update status -->
    <TextView android:id="@+id/lblUpdate" 
        android:text="Update Status"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_marginLeft="10dip"
        android:layout_marginRight="10dip"
        android:visibility="gone"/>
    
    <!-- Tweet EditText -->
    <EditText android:id="@+id/txtUpdateStatus"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_margin="10dip"
        android:visibility="gone"/>
    
    <!-- Tweet Button -->
    <Button android:id="@+id/btnUpdateStatus"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="Tweet"
        android:layout_marginLeft="10dip"
        android:layout_marginRight="10dip"
        android:visibility="gone"/>
    
    <!-- Twitter Logout button -->
    <Button android:id="@+id/btnLogoutTwitter"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="Logout from Twitter"
        android:layout_marginLeft="10dip"
        android:layout_marginRight="10dip"
        android:layout_marginTop="50dip"
        android:visibility="gone"/>

</LinearLayout>

6. Now open your main activity class (In my case MainActivity.java) file and type the following code. In the following code i am declaring required variables.

package com.androidhive.twitterconnect;

import twitter4j.Twitter;
import twitter4j.TwitterException;
import twitter4j.TwitterFactory;
import twitter4j.User;
import twitter4j.auth.AccessToken;

import android.text.Html;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;

public class MainActivity extends Activity {
	// Constants
	/**
	 * Register your here app https://dev.twitter.com/apps/new and get your
	 * consumer key and secret
	 * */
	static String TWITTER_CONSUMER_KEY = "LsCQaPOwd8k7WkyRFRZF4Q";
	static String TWITTER_CONSUMER_SECRET = "KJbJu5IQrlwxW7Cwnax3mMzAc4j3n6Wd2dG125srgk";

	static final String URL_TWITTER_AUTH = "auth_url";
	static final String URL_TWITTER_OAUTH_VERIFIER = "oauth_verifier";
	static final String URL_TWITTER_OAUTH_TOKEN = "oauth_token";

	// Login button

	// Update status button
	Button btnUpdateStatus;
	// Logout button
	Button btnLogoutTwitter;
	// EditText for update
	EditText txtUpdate;

	TextView lblUserName;

	// Progress dialog

	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
		
		cd = new ConnectionDetector(getApplicationContext());

		// Check if Internet present
		if (!cd.isConnectingToInternet()) {
			// Internet Connection is not present
			alert.showAlertDialog(MainActivity.this, "Internet Connection Error",
					"Please connect to working Internet connection", false);
			// stop executing code by return
			return;
		}
		
		// Check if twitter keys are set
		if(TWITTER_CONSUMER_KEY.trim().length() == 0 || TWITTER_CONSUMER_SECRET.trim().length() == 0){
			// Internet Connection is not present
			alert.showAlertDialog(MainActivity.this, "Twitter oAuth tokens", "Please set your twitter oauth tokens first!", false);
			// stop executing code by return
			return;
		}

		// All UI elements
		btnLoginTwitter = (Button) findViewById(R.id.btnLoginTwitter);
		btnUpdateStatus = (Button) findViewById(R.id.btnUpdateStatus);
		btnLogoutTwitter = (Button) findViewById(R.id.btnLogoutTwitter);
		txtUpdate = (EditText) findViewById(R.id.txtUpdateStatus);
		lblUpdate = (TextView) findViewById(R.id.lblUpdate);
		lblUserName = (TextView) findViewById(R.id.lblUserName);

		// Shared Preferences
		mSharedPreferences = getApplicationContext().getSharedPreferences(
				"MyPref", 0);


Login with Twitter Account

Login with twitter account in your android application involves following process.

- First user asked to authenticate into your application using their twitter account.
- Once user successfully logged into his twitter account we will receive his oauth token and oauth secret.
- oauth token and oauth secret will be stored in android application shared preferences.
- Whenever you need oauth tokens, you can read from shared preferences.
- Once user clicks logout button we will delete oauth token & secret from shared prefrences

7. Open your main activity and write click event for login button.

> In click event i am calling loginToTwitter().
> Once the user logins into twitter he will be redirected to your android app again with oauth verifier.
> Using oauth verifier we do another request to get access token and access token secret.

		/**
		 * Twitter login button click event will call loginToTwitter() function
		 * */
		btnLoginTwitter.setOnClickListener(new View.OnClickListener() {

			@Override
			public void onClick(View arg0) {
				// Call login twitter function
				loginToTwitter();
			}
		});

		/** This if conditions is tested once is
		 * redirected from twitter page. Parse the uri to get oAuth
		 * Verifier
		 * */
		if (!isTwitterLoggedInAlready()) {
			Uri uri = getIntent().getData();
			if (uri != null && uri.toString().startsWith(TWITTER_CALLBACK_URL)) {
				// oAuth verifier
				String verifier = uri
						.getQueryParameter(URL_TWITTER_OAUTH_VERIFIER);

				try {
					// Get the access token
					AccessToken accessToken = twitter.getOAuthAccessToken(
							requestToken, verifier);

					// Shared Preferences
					Editor e = mSharedPreferences.edit();

					// After getting access token, access token secret
					// store them in application preferences
					e.putString(PREF_KEY_OAUTH_TOKEN, accessToken.getToken());
					e.putString(PREF_KEY_OAUTH_SECRET,
							accessToken.getTokenSecret());
					// Store login status - true
					e.putBoolean(PREF_KEY_TWITTER_LOGIN, true);
					e.commit(); // save changes

					Log.e("Twitter OAuth Token", "> " + accessToken.getToken());

					// Hide login button
					btnLoginTwitter.setVisibility(View.GONE);

					// Show Update Twitter
					lblUpdate.setVisibility(View.VISIBLE);
					txtUpdate.setVisibility(View.VISIBLE);
					btnUpdateStatus.setVisibility(View.VISIBLE);
					btnLogoutTwitter.setVisibility(View.VISIBLE);
					
					// Getting user details from twitter
					// For now i am getting his name only
					long userID = accessToken.getUserId();
					User user = twitter.showUser(userID);
					String username = user.getName();
					
					// Displaying in xml ui
					lblUserName.setText(Html.fromHtml("<b>Welcome " + username + "</b>"));
				} catch (Exception e) {
					// Check log for login errors
					Log.e("Twitter Login Error", "> " + e.getMessage());
				}
			}
		}

	}

and code for loginToTwitter() function is

/**
	 * Function to login twitter
	 * */
	private void loginToTwitter() {
		// Check if already logged in
		if (!isTwitterLoggedInAlready()) {
			ConfigurationBuilder builder = new ConfigurationBuilder();
			builder.setOAuthConsumerKey(TWITTER_CONSUMER_KEY);
			builder.setOAuthConsumerSecret(TWITTER_CONSUMER_SECRET);
			Configuration configuration = builder.build();
			
			TwitterFactory factory = new TwitterFactory(configuration);
			twitter = factory.getInstance();

			try {
				requestToken = twitter
						.getOAuthRequestToken(TWITTER_CALLBACK_URL);
				this.startActivity(new Intent(Intent.ACTION_VIEW, Uri
						.parse(requestToken.getAuthenticationURL())));
			} catch (TwitterException e) {
				e.printStackTrace();
			}
		} else {
			// user already logged into twitter
			Toast.makeText(getApplicationContext(),
					"Already Logged into twitter", Toast.LENGTH_LONG).show();
		}
	}

	/**
	 * Check user already logged in your application using twitter Login flag is
	 * fetched from Shared Preferences
	 * */
	private boolean isTwitterLoggedInAlready() {
		// return twitter login status from Shared Preferences
		return mSharedPreferences.getBoolean(PREF_KEY_TWITTER_LOGIN, false);
	}
android twitter login
android twitter login oauth
android twitter login get username


Update Twitter Status

8. Once you login with twitter account you can see interface to update the status. Open your main activity class write a click event for update status button.

> In the following code async thread updateTwitterStatus() is called on clicking update status button.

/**
		 * Button click event to Update Status, will call updateTwitterStatus()
		 * function
		 * */
		btnUpdateStatus.setOnClickListener(new View.OnClickListener() {

			@Override
			public void onClick(View v) {
				// Call update status function
				// Get the status from EditText
				String status = txtUpdate.getText().toString();

				// Check for blank text
				if (status.trim().length() > 0) {
					// update status
					new updateTwitterStatus().execute(status);
				} else {
					// EditText is empty
					Toast.makeText(getApplicationContext(),
							"Please enter status message", Toast.LENGTH_SHORT)
							.show();
				}
			}
		});

and code for updateTwitterStatus() async task is

	/**
	 * Function to update status
	 * */
	class updateTwitterStatus extends AsyncTask<String, String, String> {

		/**
		 * Before starting background thread Show Progress Dialog
		 * */
		@Override
		protected void onPreExecute() {
			super.onPreExecute();
			pDialog = new ProgressDialog(MainActivity.this);
			pDialog.setMessage("Updating to twitter...");
			pDialog.setIndeterminate(false);
			pDialog.setCancelable(false);
			pDialog.show();
		}

		/**
		 * getting Places JSON
		 * */
		protected String doInBackground(String... args) {
			Log.d("Tweet Text", "> " + args[0]);
			String status = args[0];
			try {
				ConfigurationBuilder builder = new ConfigurationBuilder();
				builder.setOAuthConsumerKey(TWITTER_CONSUMER_KEY);
				builder.setOAuthConsumerSecret(TWITTER_CONSUMER_SECRET);
				
				// Access Token 
				String access_token = mSharedPreferences.getString(PREF_KEY_OAUTH_TOKEN, "");
				// Access Token Secret
				String access_token_secret = mSharedPreferences.getString(PREF_KEY_OAUTH_SECRET, "");
				
				AccessToken accessToken = new AccessToken(access_token, access_token_secret);
				Twitter twitter = new TwitterFactory(builder.build()).getInstance(accessToken);
				
				// Update status
				twitter4j.Status response = twitter.updateStatus(status);
				
				Log.d("Status", "> " + response.getText());
			} catch (TwitterException e) {
				// Error in updating status
				Log.d("Twitter Update Error", e.getMessage());
			}
			return null;
		}

		/**
		 * After completing background task Dismiss the progress dialog and show
		 * the data in UI Always use runOnUiThread(new Runnable()) to update UI
		 * from background thread, otherwise you will get error
		 * **/
		protected void onPostExecute(String file_url) {
			// dismiss the dialog after getting all products
			pDialog.dismiss();
			// updating UI from Background Thread
			runOnUiThread(new Runnable() {
				@Override
				public void run() {
					Toast.makeText(getApplicationContext(),
							"Status tweeted successfully", Toast.LENGTH_SHORT)
							.show();
					// Clearing EditText field
					txtUpdate.setText("");
				}
			});
		}

	}

andorid update twitter status


Logout from Twitter

9. Open your main activity and write a click event for logout button. Please remember this logout code won’t logout user from the twitter in the browser. It will just clear the access tokens from your application shared preferences.

		/**
		 * Button click event for logout from twitter
		 * */
		btnLogoutTwitter.setOnClickListener(new View.OnClickListener() {

			@Override
			public void onClick(View arg0) {
				// Call logout twitter function
				logoutFromTwitter();
			}
		});

and code for logoutFromTwitter() function is

	/**
	 * Function to logout from twitter
	 * It will just clear the application shared preferences
	 * */
	private void logoutFromTwitter() {
		// Clear the shared preferences
		Editor e = mSharedPreferences.edit();
		e.remove(PREF_KEY_OAUTH_TOKEN);
		e.remove(PREF_KEY_OAUTH_SECRET);
		e.remove(PREF_KEY_TWITTER_LOGIN);
		e.commit();

		// After this take the appropriate action
		// I am showing the hiding/showing buttons again
		// You might not needed this code
		btnLogoutTwitter.setVisibility(View.GONE);
		btnUpdateStatus.setVisibility(View.GONE);
		txtUpdate.setVisibility(View.GONE);
		lblUpdate.setVisibility(View.GONE);
		lblUserName.setText("");
		lblUserName.setVisibility(View.GONE);

		btnLoginTwitter.setVisibility(View.VISIBLE);
	}
