How to Post Twitter Status from Android

Home » Information Technology » Programming » Android » How to Post Twitter Status from Android

While developing one of my Android application, i found it was hard to find a good and simple tutorial on how to integrate Twitter into Android app.  There are some external java libraries over the net that can be used to integrate Twitter into Android app, but they lack of good documentation and tutorial on how to use it on Android. So i  made my own implementation using  Twitter4j and oauth-signpost library. In this tutorial, i create one sample Android project to show how to connect to Twitter, save it’s token and username on shared preferences so it can be used later to post status to Twitter.

I. Register Twitter Application

To enable user to post status to Twitter, first you have to create one Twitter application. Simply go to Twitter Apps page and register your application. Fill the ‘Application Name‘ with your desired name, it has to be unique. If you use a name that already exist (taken by someone), you’ll get a warning message.  On ‘Application Type’ option, choose ‘Browser’ , and because its a browser type application but used in mobile application, you can set it’s callback url on ‘Callback URL‘ field  with any url you want. On ‘Default Access type’, choose ‘Read and Write‘ to enable access to post status. Click save and if all things going well, you’ll get a page showing your consumer key and secret key. Copy these two keys for later use in Android app.

II. Android Integration

To integrate Twitter into Android app, you need four external jar files from two different libraries, Twitter4j and oauth-signpost. You can download latest version from Twitter4j download page or use the one included in my sample project (twitter4j-core-2.1.6.jar) and oauth-signpost from oauth-signpost download page (signpost-core-1.2.1.1.jar, signpost-commonshttp4-1.2.1.1.jar, signpost-jetty6-1.2.1.1.jar). Add the four external jars into your Android project (on Eclipse, right click on your project->properties then on Java Build Path click Add External JARs button to select files)

In my sample project, i create three helper classes (TwitterApp.java,  TwitterDialog.java, and TwitterSession.java) to handle authentication using Webview Dialog and session handler to save token and username on Shared Preferences.

Code implementation

1. Twitter Connection (TestConnection.java)

This example shows how to connect to Twitter, display webview dialog to authorize user then save user’s token and username on shared preference for later use.

public class TestConnect extends Activity {
	private TwitterApp mTwitter;
	private CheckBox mTwitterBtn;

	private static final String twitter_consumer_key = "xxx";
	private static final String twitter_secret_key = "xxx";

	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);

		setContentView(R.layout.main);

		mTwitterBtn	= (CheckBox) findViewById(R.id.twitterCheck);

		mTwitterBtn.setOnClickListener(new OnClickListener() {
			@Override
			public void onClick(View v) {
				onTwitterClick();
			}
		});

		mTwitter 	= new TwitterApp(this, twitter_consumer_key,twitter_secret_key);

		mTwitter.setListener(mTwLoginDialogListener);

		if (mTwitter.hasAccessToken()) {
			mTwitterBtn.setChecked(true);

			String username = mTwitter.getUsername();
			username		= (username.equals("")) ? "Unknown" : username;

			mTwitterBtn.setText("  Twitter (" + username + ")");
			mTwitterBtn.setTextColor(Color.WHITE);
		}

		Button goBtn = (Button) findViewById(R.id.button1);

		goBtn.setOnClickListener(new OnClickListener() {
			@Override
			public void onClick(View v) {
				startActivity(new Intent(TestConnect.this, TestPost.class));
			}
		});
	}

	private void onTwitterClick() {
		if (mTwitter.hasAccessToken()) {
			final AlertDialog.Builder builder = new AlertDialog.Builder(this);

			builder.setMessage("Delete current Twitter connection?")
			       .setCancelable(false)
			       .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
			           public void onClick(DialogInterface dialog, int id) {
			        	   mTwitter.resetAccessToken();

			        	   mTwitterBtn.setChecked(false);
			        	   mTwitterBtn.setText("  Twitter (Not connected)");
			        	   mTwitterBtn.setTextColor(Color.GRAY);
			           }
			       })
			       .setNegativeButton("No", new DialogInterface.OnClickListener() {
			           public void onClick(DialogInterface dialog, int id) {
			                dialog.cancel();

			                mTwitterBtn.setChecked(true);
			           }
			       });
			final AlertDialog alert = builder.create();

			alert.show();
		} else {
			mTwitterBtn.setChecked(false);

			mTwitter.authorize();
		}
	}

	private final TwDialogListener mTwLoginDialogListener = new TwDialogListener() {
		@Override
		public void onComplete(String value) {
			String username = mTwitter.getUsername();
			username		= (username.equals("")) ? "No Name" : username;

			mTwitterBtn.setText("  Twitter  (" + username + ")");
			mTwitterBtn.setChecked(true);
			mTwitterBtn.setTextColor(Color.WHITE);

			Toast.makeText(TestConnect.this, "Connected to Twitter as " + username, Toast.LENGTH_LONG).show();
		}

		@Override
		public void onError(String value) {
			mTwitterBtn.setChecked(false);

			Toast.makeText(TestConnect.this, "Twitter connection failed", Toast.LENGTH_LONG).show();
		}
	};
}

First, create an instance of  TwiterApp class with context, consumer key and secret key as constructor’s parameters. Use hasAccessToken() method to check if there is previously saved session. If there is no saved session, call authorize() to open authorization dialog. If user allows the connection, his access token and user name will be saved on shared preferences. You can setup listener to handle on success and on error event by creating an instance of TwDialogListener and pass it to setListener() method.

2. Post Status (TestPost.java)

This example shows how to post Twitter status. If there is no previously saved session, display authorization dialog to allow user authorize the connection then post status using different thread.

public class TestPost extends Activity {
	private TwitterApp mTwitter;
	private CheckBox mTwitterBtn;
	private String username = "";
	private boolean postToTwitter = false;

	private static final String twitter_consumer_key = "xxxx";
	private static final String twitter_secret_key = "xxxx";

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);

		setContentView(R.layout.post);

		Button postBtn 				= (Button) findViewById(R.id.button1);
		final EditText reviewEdit   = (EditText) findViewById(R.id.revieew);

		postBtn.setOnClickListener(new OnClickListener() {
			@Override
			public void onClick(View v) {
				String review = reviewEdit.getText().toString();

				if (review.equals("")) return;

				postReview(review);

				if (postToTwitter) postToTwitter(review);
			}
		});

		mTwitter = new TwitterApp(this, twitter_consumer_key,twitter_secret_key);

		mTwitter.setListener(mTwLoginDialogListener);

		mTwitterBtn	= (CheckBox) findViewById(R.id.twitterCheck);

		mTwitterBtn.setOnClickListener(new OnClickListener() {
			@Override
			public void onClick(View v) {
				if (mTwitter.hasAccessToken()) {
					postToTwitter = mTwitterBtn.isChecked();
				} else {
					mTwitterBtn.setChecked(false);
					mTwitter.authorize();
				}
			}
		});

		if (mTwitter.hasAccessToken()) {
			username 	= mTwitter.getUsername();
			username	= (username.equals("")) ? "No Name" : username;

			mTwitterBtn.setText("  Twitter  (" + username + ")");
		}
	}

	private void postReview(String review) {
		//post to server

		Toast.makeText(this, "Review posted", Toast.LENGTH_SHORT).show();
	}

	private void postToTwitter(final String review) {
		new Thread() {
			@Override
			public void run() {
				int what = 0;

				try {
					mTwitter.updateStatus(review);
				} catch (Exception e) {
					what = 1;
				}

				mHandler.sendMessage(mHandler.obtainMessage(what));
			}
		}.start();
	}

	private Handler mHandler = new Handler() {
		@Override
		public void handleMessage(Message msg) {
			String text = (msg.what == 0) ? "Posted to Twitter" : "Post to Twitter failed";

			Toast.makeText(TestPost.this, text, Toast.LENGTH_SHORT).show();
		}
	};
	private final TwDialogListener mTwLoginDialogListener = new TwDialogListener() {
		@Override
		public void onComplete(String value) {
			username 	= mTwitter.getUsername();
			username	= (username.equals("")) ? "No Name" : username;

			mTwitterBtn.setText("  Twitter  (" + username + ")");
			mTwitterBtn.setChecked(true);

			postToTwitter = true;

			Toast.makeText(TestPost.this, "Connected to Twitter as " + username, Toast.LENGTH_LONG).show();
		}

		@Override
		public void onError(String value) {
			mTwitterBtn.setChecked(false);

			Toast.makeText(TestPost.this, "Twitter connection failed", Toast.LENGTH_LONG).show();
		}
	};
}

Update 2011-10-01

- Fix authorization failed bug when attempt to authorize after logging out. This was caused by an exception (java.lang.IllegalStateException: consumer key/secret pair already set) was thrown by setOauthConsumer(consumerKey,secretKey) method of Twitter class. This method should be called once.

You can download  the source code here (with external jars) or via github here

    Just in case anyone wanted to know how to clear the user’s credentials from the Twitter webview… (In addition to clearing the access token from the app’s shared preferences, this modification forces the user to re-enter their username and password on the Twitter webview when signing back-on).

    1. In twitterapp.java, replace resetAccessToken function with this:

    public void resetAccessToken(Context context) {
    if (mAccessToken != null) {
    mSession.resetAccessToken();

    //clear webview cookies (in case user saved credentials on Twitter webview)
    CookieSyncManager.createInstance(context);
    CookieManager cookieManager = CookieManager.getInstance();
    cookieManager.removeAllCookie();

    mAccessToken = null;
    }
    }

    2. From main activity, call:

    mTwitter.resetAccessToken(this);

    Hi, I need a help about that codes.

    I downloaded your project. It’s working properly. But I wanted to build my own app. I imported the jar files. There is no problem. Then I take your TwitterApp.java file, TwitterDialog.java file and TwitterSession.java files to my package. I’m trying to login to twitter when I click on a button. When I create the instance of TwitterApp I got a problem. It gives me error on this code;

    mTwitter = new TwitterApp(getApplicationContext(), twitter_consumer_key,
    twitter_secret_key);

    and then crashes the application.

    I couldn’t figure it out

      Hi Rubyd,

      1) Remove the libraries from the standard Java build path :

      Right click on the project name > Properties > Java Build Path > tab Libraries > remove everything except the “Android X.X” (2.3.3 in my case) and the “Android Dependencies”

      2) Copy the jar files into libs folder :

      a. Create “libs” folder in your project directory without double quotes.

      b. Copy all the required jar files and paste in libs folder.

      c. clean the project.

      By doing that, all the libraries in the folder “libs” are found by the Android plugin and are added to the “Android Dependencies” item of the project

      Thanks,
      RAMESH ANNADURAI

    Hi,

    I downloaded your application and just modified the twitter_consumer_key and twitter_secret_key and set it to my app key. Im using android 2.3.3. Looks like its not working perfectly.

    The problem is the app unable to connect to twitter.

    ACCESS_TOKEN = “https://api.twitter.com/oauth/access_token”;
    AUTHORIZE = “https://api.twitter.com/oauth/authorize”;

    and now it works… But i have a problem with CALLBACK_URL… I’ve set it to None when i create twitter app and now it’s not returning token to app, just require user to get pin code into app, and stuck there… What should i do? How should the CALLBACK_URL be?

      I managed to make it work by re-initializing instance, like this..

      mTwitter.resetAccessToken(this);
      mTwitter = new TwitterApp(this, consumerKey,consumerSecret);
      mTwitter.setListener(mTwLoginDialogListener);
      mTwitter.authorize();

      not sure if this is the right way, but works for me :)

    Hi I’m having a problem connecting to twitter (program starts up in my eclipse emulator and when I click on “Twitter (not connected)” and it tries to connect it comes back with “Twitter Connection Failed”)(the emulator does have an internet connection). I’ve set the twitter_consumer_key and twitter_secret_key in both TestPost.java and TestConnect.java with my own. Other than that I have not changed or added anything else to the code (gotten from github).
    Is there anything else I need to set in the code to connect to Twitter. I would assume there would need to be some sort of username and password, though if it connects to twitter then I would assume Twitter would handle that instead of your code.

    - WARNING: Application does not specify an API level requirement!
    - Device API version is 10 (Android 2.3.7)

    What should I do?
    I use debuging usb connection.
    I debug your facebook connection code before. It work correctly. But I got error on your twitter connection code.
    Help me please.

    I’m very new to android, and still learning how to develop an android program.

    I did exactly these steps, but in the end my program is unexpectedly force closed.

    When I checked on the LogCat it show like this:
