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 its 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

Hi,
Thanks very much it help me lot to solve my problem.
You’re welcome ……
Can Only TwitterApp.java itself can post the message on twitter.
Where is the password getting updated ?
This tutorial is pretty awesome. I m using it in the android facebook app to connect to twitter
Hey are you using Sugree’s API?
i cant connect twitter
when i download yr app
i add external jar then copy and replace
my cunsumer key and consumer secret in yr app but when i run emulator and click
checkbox to connect , app show “Twitter connection failed”
because mTwitter.hasAccessToken() = false
Login dilaog is not show
Hey supertoonz,
I have the same problem with you.
I resolved this problem, i forget to change the callback url.
Try this.
Thanks for this tutorial !
++
thank you . it’s work.
Hey super,
what should be the callback url?
Have you got it working..I am also having the same problem..
Hi, you can put any url as callback url
I also get the same prob.
What is mean by callback Url.
Callback url is used on web based app. If your app is a mobile application, you can put any url as Callback URL.
Is there any way of deleting the recently posted status in twitter from android..?
i am also getting “Twitter connection failed” on device but its working correct on emualator. . . Can you tell me What the mistake i am doing ? ? ?
Thanks in advance.
same prob
Thanks so much, i’m try it :).
I worked but method getAccessToken() return “null” . I trying but not work, please help me. I was post my project on mediafire: http://www.mediafire.com/?0vard7jimbco3rd
I changed call back URL but don’t work.
Hi PvTai, on web settings, have set the ‘Application Type’ to browser? and also on TwitterApp.java, use ” public static final String CALLBACK_URL = “twitterapp://connect” ” instead of public static final String CALLBACK_URL = “http://twitter.com/#!/QGSVietnam”
Ok, I have done. thanks.
but I see you said “you can put any url as Callback URL.”
So why now are you saying to use ” public static final String CALLBACK_URL = “twitterapp://connect” ” instead of public static final String CALLBACK_URL = “http://twitter.com/#!/QGSVietnam”. I really do not understand about this issue.
You can say more to you, please.
Hi..
Article is helpful to begineers like me but when i download ur app i hve error in TwitterApp.java in the CommonsHttpOAuthConsumer and OAuthProvider java class. it ask me to create new class with this name.. how to solve this problem?
Hi, I have downloaded yr app and it works.
Now I am trying to learn it and writing my app. While I have a question, why do u use Handler in TwitterApp.java? Why don’t u authorize directly?
I tried to use startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(url)) and onNewIntent(Intent) to get the verifier. But when I ran it on the TwitterApp.java, it turned out to be NullnotFound? Can you help me
Thats a network operation and may block the main process, so its better to separate it from main thread.
Hi,
thanks for this tutorial, bt im unable see the tweets sent on my twitter account,plz help
Hi,
i solved the issue, i just commented these lines in Testost ie.,
if (review.equals(“”)) return;
postReview(review);
if (postToTwitter) postToTwitter(review);
and called postToTwitter instead,
hope this helps sumbody,
thanks
Hey are you using Sugree’s SDK?
Hey are you using sugree’s SAL?
Hi i got this error:
04-25 14:07:51.188: WARN/System.err(322): oauth.signpost.exception.OAuthCommunicationException: Communication with the service provider failed: Received authentication challenge is null
Can you help me?
Thanks
Hi, the problem caused by oauth-signpost lib. I never got that problem. You may look at this issue: http://code.google.com/p/oauth-signpost/issues/detail?id=21
Hi lorenz,
can you get sugree’s sdk working, as im unable to post tweets using his code.
Can I sign out from the twitter account using your TwitterApp class?
You don’t have to signout, there is no session like facebook. Just delete the token using resetAccessToken method on TwitterApp.java
Hi Lorenz,
This seems to be wrong. Because after i deleted the access token and restarted the application and again tryed to sign in, i still can see the user profile picture and “Signout” option in Twitter WebView Page(on top right corner). And in that web page there are no editfields to receive fresh username and password.
I am guessing that Twitter Webpage has stored there credentials in it’s own shared preferences.
How can we completely clear all login info so that it wont show those details again?
Hi Naga,
You can use webview’s clearCache() method to delete all caches.
Hi,
Thanks for providing the information. I tried working on it. When I connect it to the mobile phone. and Press the Tweet Post button, it does not initiate anything. as in No Response. And it is mentioned that the twitter account is also Not connected. the Callback Url is the new value only. It would be helpful of you.
Did you change the callback url constant in TwitterApp.java ?
the callback url is “twitterapp: //connect”… Do you want me to change this callback url?
Nope, don’t change it
Hi lorenz……
Thanks a lot it works…
i try your code ,it works fine could u pls tell how to add filter API in this apps.
pls help.
Hey ppl , I m not able to debug !!! i m getting Twitter Connection Failed ! I changed callback url !!
I m not getting the dialog box where we have to enter the username password . pls post any perfectly working code !!
Don’t change the callback url in TwitterApp.java
Hi, i am trying your code and i have consumer as well secret key but all the time i am getting System error oauth.singpost.exception.OAuhtCommunicationException: communication with the service provider failed: http//twitter.com/oaut/request_token, i tried to resolve it but i can’t figure it out.
Did you get it working? i am having the same problem.
hello!
thank you very much for this article.
I have 2 question:
1)when “deny” is pressed, should the webview be dismissed or do I have to add some code?
2)my boss wants me to write an application that can post on twitter without user interaction (I have login and password), but I dont think it is possible anymore, since now we have to deal with oauth. Am I right?
regards
Hi everyone,
I would like to close the authorize dialog box, when user clicks on “No Thanks.” How can I make it happen.
thanks
Sameer
still i m facing the same prob !! so please anyone post perfectly working code !!
I figure it out its DefaultOAuther use CommonsHttpOAuth but still getting 401 error.
Hi Piyush, coud you give me your sampe project (delete the keys first)?
Thank you very, very much for a clear and concise description on how to get this working. Well done.
Hi,
I am trying to integrate the Twitter in to my App. I registered the app and got the consumer key as well as the secret key too. Whenever i tried to refer those in the code and execute the app, it gives me the following error.

Hi, could you give me your sample project? (delete your key first)
how can i send it to you? via mail?
thank you it is very helpful. But I didn’t see my statu twitter.
Hi,
I am learning android from learning android book . Thanks for this wonderful post . Can i connect to twitter without registering my application , just by calling the twitter constructor and update status as i don’t have a url to register.
hi, when i try to authorize, dialog box does not open, instead i get twitter connection failed message. My callback url is “twitterapp://connect” . I changed DefaultOAuther to CommonsHttpOAuth .I cant figure out what i am doing wrong.
Could you provide the error log from logcat ?

Hi, you may refer to this discussion:
http://code.google.com/p/oauth-signpost/wiki/TwitterAndSignpost
Thanks a lot for this beneficial tutorial.
I have a problem that when the pin is displayed in the twitter web view , i am trapped and cant return to my application
do i have to add something to get this working or am missing something here?
waiting for your reply
Hi Ahmed, i’m not using pin based auth in this tutorial. have u tried the code in this tutorial ?
Hi lorenz ,
I hace downloaded your application but whenever i run and click on twitter i get a toast twitter connection failed….please help guys
Have u done all the settings correctly? any error log info?
for all those who receive the 401 error: check if the time on the device is set correctly, otherwise it is impossible to receive the authentication for the fact that the validity has expired
Hey, thanks for great tutorial. I have only changed DefaultOAuther to CommonsHttpOAuth and added my own keys. The problem is that t wont work on my device over wifi, but when going over 3G or on the emulator it works just fine.
It just displays loding for a while after i’ve put in my mail and passwor, then it shows “Twitter connection failed”.

Hi!!
Thanks for the awesome twitter app! I only have one question: Why it has to be type “browser”?
A twitter app for android isn’t a client type?
Thanks!
Best Regards,
Thanks for step-by-step process and sample code…
But i have question regarding “Application Type” – as we have implemented twitter related stuff in iPhone where it requires “Application Type” as “Client” – now if i change to “Browser” iPhone implementation stop working… Any help or pointer on this will be appreciated.
This is definitely not working. Twitter has not only changed the addresses, plus now is necessary to register a domain to access the application. I haven’t been able yet to post a solution, hope to make it soon
I’m getting similar errors like one of the members from above. I’ve been on this for awhile, this will be my first time connecting to the internet from an android app. I’m sure it has to do with my Twitter & code configurations. So, your help is greatly appreciated.
Here’s the error when run app example:
‘twitter (not connected)’
Here’s the error after pressing post:
‘post to twitter failed’
Let me know if you need more info. Thanks
Hello, could you give me the log cat error?
I hope you don’t mind the long log:

Hi pvu, this is not what i ment. Copy the logcat error from ddms.
I sent it out twice, but it’s not showing up in the forum. Hmmm, maybe it was too long. Let me know if I can send an attachment to you.
Hi,
Thanks for this awesome post. It is very helpful. Would you like to tell, is it possible to post all these three things (some Text + any image from sd card + any url or link ) in a single post.
Kind regards,
Muhammad Rashid

Hi Lorenz..!
I am getting the following exception while running the app in DEVICE, but where as in EMULATOR it’s working properly..
oauth.signpost.exception.OAuthCommunicationException: Communication with the service provider failed: Received authentication challenge is null
I nedd the solution as early as possible
Kiran Kala
Hi Kiran, i don’t know what exactly cause the problem. Error ‘Received authentication challenge is null’ may raised when
java.net.HttpURLConnection receives a 401 (Unauthorized) from the server. Do you use different sdk on emulator and device?
Hi Lorenz..!
I am eagerly waiting for your response..,and I have one more query
i.e.,whether TWITTER will work in Android 2.1 or not, because..My application is working for 2.2 but not its not supported it 2.1, when I tried to execute in 2.1 I am getting the above error..
Kiran Kala
updateStaus not working using twitter4j-core2.1.6. and throws an exception is there any change that i need to make
Hi guys! I have the same issue as Kiran Kala. 2.2 and above is working and on a 2.1 device or emulator is not. Does somebody have any idea why is this happening?
Thanks!
Andi
Thanks for the guide. I thought I would post my experience.
1) Didn’t work with latest twitter4j-2.2.4 build. Sorry, I didn’t keep the error output, but the problems seems to be that package paths have changed. I used the 2.1.6 branch bundled in the ExtJars file to resolve the problem.
2) Instructions for setting application type have changed. There is no more option for setting application type to Browser. Instead you just need to specify a callback URL or you will see this error in the debug output.
java.io.FileNotFoundException: https://api.twitter.com/oauth/request_token
I found this message in a TCP packet capture.
/oauth/request_token Desktop applications only support the oauth_callback value ‘oob’
Here is some additional information.

Seems like you had problem with authorization, did you finish the authorization process?
yes i did…i got this working, i had a problem with proxy server access.
Thx for quick answer.
Anyway, i need to have option of changing twitter account. How do I do that?
I’ve add a new button, and on click, im doing this:
mTwitter.resetAccessToken();
mTwitter.configureToken();
mTwitter.authorize();
after seting up new user name and password in authorize dialog, im getting “Twitter connecection failed”
in logcat im getting:

Hi, have u tried to create new instance of TwitterApp ?
Hey, yes i did.
This code runs in moment when im logged on twitter with one account. When i click on “change account” button, i need to log out, and sign in as a different user…You know what i mean?
in changeAccount onClickListener i do this:
mTwitter = null;
mTwitter = new TwitterApp(getBaseContext(),
twitter_consumer_key, twitter_secret_key);
mTwitter.resetAccessToken();
if (mTwitter.hasAccessToken()) {
postToTwitter = mTwitterBtn.isChecked();
} else {
mTwitterBtn.setChecked(false);
mTwitter.authorize();
}
The logcat gives me this:

Hi lorenz, it works like a champ! But im having a problem. After I authorize my app on twitter it returns me a PIN… it says i have to go back to my app and type in the given PIN, but… not sure how to do that…
Thanks,!
Nico.
My problem is that..my twitter dialog doesnt get disapper after authorization.
Many thanks Loren’z, your post helped a lot.
Thanks a lot for this lorenz!
The only problem I run into is that using 2.1 API level after I enter my credentials and try to login a blank page appears and nothing is happening.

Do you use Android 2.1? Try to use api.twitter.com instead of twitter.com on:
mHttpOauthprovider = new DefaultOAuthProvider(“http://twitter.com/oauth/request_token”,
“http://twitter.com/oauth/access_token”,
“http://twitter.com/oauth/authorize”);
i always error authencticate at class TestConnect “Twitter Connection Failed”, but if i authenticate at TestPost i always success, why it happen? as i know they use a same function but the result is different? ?
but when i use all of that in my project, two class of them can’t be used, both “Twitter Connection Failed”
what is the actually reason that error? the problem is confused for me, T_T
give me the logcat…
hi its shows twitter connection failed

Hi Lorenz,

Hi Kaushal, sorry i have no experience on Sencha Touch…i can’t give u suggestion
Greetings,
Having an issue w/ TwitterApp.java, line 115:
authURL = mHttpOauthprovider.retrieveRequestToken(mHttpOauthConsumer, CALLBACK_URL);
All that my application is doing, is creating the TwitterApp object, setting the listener, checking for accessToken (authorize if not) and then attempting to post.
If I use https oauth URLs, I get a runtime error:
OAuthCommunicationsException
cause- IOException
detail message- Communication with the service provider failed: Hostname ‘api.twitter.com’ was not verified
If I use http oauth URLs, I get a different error:
OAuthCommunicationsException
cause- FileNotFoundException
detail message- Communication with the service provider failed: http://api.twitter.com/oauth/request_token
I’ve searched and searched and cannot find any solution to this. Any assistance would be appreciated.
Thanks,
Aaron
After a little more experimentation, I was able to get by this by entering a valid URL for the Callback URL on dev.twitter.com/apps and placing the exact same URL in my app.
This only works with http, https still throws the same error.
Regards,
Aaron
Great find..i’ll also try to find the answer..
api.twitter.com should work on android 2.1 and above. If you use twitter.com/oauth you may have issue with android 2.1. Did u test in emulator or on real device?

In TwitterApp.java, the url should be like this;
mHttpOauthprovider = new DefaultOAuthProvider(“http://api.twitter.com/oauth/request_token”,
“http://api.twitter.com/oauth/access_token”,
“http://api.twitter.com/oauth/authorize”);
Hi,
Ive changed to api.twitter.com for the oauth url but i still cant connect to twitter.
Thanks.
Have u set the callaback url on twitter app web settings?
Hi lorenz. Thanks for the great work. I do all of this (I’ve downloaded your zip file and altered it slightly for my consumer key and secret key, but I can’t get the web view to return to the app. It just goes to the callback URL. I use the callback url http://redir.domain.com (domain is actually replaced with my client’s domain name). My web host sends .domain.com to http://www.domain.com, so the webview just shows the http://www.domain.com page.
I hope these screenshots help to explain the situation I’m up against.
#1:

When I run the sample code in the zip file, I get an authorization screen from Twitter in a WebView
#2:
http://www.fountaindew.com/screenshot2.png
When I select to authorize, it says it’s “redirecting you back to the application…”, but it never goes back to the application.
#3:

Instead, the WebView shows the home page that the redirect URL eventually goes to. The WebView never goes away, and I never get a token to store in the preferences of the app.
Hi Jeff,
It should return to app. The callback url has no effect on mobile app, it only works for web app. Where did u run the app? what version of android?
hello, i am getting this error when i click connect button,knowing that i set the consumer key and consumer secret key below this is my log file when i pressed connect button:

Any Luck for help please :)? this is exactly what i need for my app.
Have u set the callback url on twitter web settings page?
Hi lorenz
Great tutorial. I am a noob to android api and eclipse and stuff, I am facing a problem. I downloaded the jar files that you said, added them to my project. I had created a new project by the name flixtermovie. Now to create the classes TestConnection.java, I right click the src folder of my project flixtermovie and click add class and ype in the name, after that I copy pasted your code.
The problem is, there are lots of errors, most of them being “cannot be resolved to type” for various things like Activity, TwitterApp,CheckBox and so on,. Im guessing my libraries are not called properly, how do i solve this issue and get your code working on my computer? Please help me out, thanks a lot.
Regards
I think you forget to import the required class first (Activity,Checkbox etc)..
Can I please have the code to helper classes? Thanks again
What do you mean helper classes? all codes are available on github as referenced in my tutorial.
can tell me import files because it can not declare
private TwitterApp mTwitter;
Hi lorenz,
One thing I noticed is once I logged out, next it will not lead me to login page at all. Why it so? Pls reply me.
Hi Ian, the problem was fixed in the latest version on github. Try to download the source code from github.
Hey Lorenz,
It seems that even with that fix implemented in October for some reason the second log-in is showing a blank WebView. The first time the user logs in, the Redirecting URL receives an oauth verifier as a parameter, where as the second time the Redirecting URL only contains the oauth token.
Any help is appreciated. Thanks for the great tutorial.
Hi Dave,thanks for your info. I’ve tested on nexus s with GB and froyo on emulator they works fine. I’ll try to test it again and find the bug.
I believe I actually fixed it. The problem seemed that the web view still considered me logged in even if I reset my preferences/token. In the shouldOverrideUrlLoading method in the TwitterDialog class it was always returning true even if my URL did not start with the CallBack URL. With this in mind I changed the line:
else if (url.startsWith(“authorize”)) {
return false;
}
to
} else if (url.contains(“authorize”)) {
return false;
}
and it seems to have fixed my problem. I don’t think this will cause other issues but now when the user wants to log out they are technically signed into the browser they just need to sign out of it as well or just re-authorize the application if they wish.
If it helps, I have been testing on a Samsung Galaxy S running Android 2.3.3.
ok thank you Dave..
Ok i see, the problem is on webview. thank you for the solution, i have to test it again and make sure it will not cause other issues.
Hi lorenz,

hi,

Can u plz give me the solution for this.
Thanks & Br,
Yogi
To get this working :
* set the callback url on twitter web settings page to :
https://dev.twitter.com/app
* change this :
mHttpOauthprovider = new DefaultOAuthProvider(”http://twitter.com/oauth/request_token”,
“http://twitter.com/oauth/access_token”,
“http://twitter.com/oauth/authorize”);
to this :
mHttpOauthprovider = new DefaultOAuthProvider(”http://api.twitter.com/oauth/request_token”,
“http://api.twitter.com/oauth/access_token”,
“http://api.twitter.com/oauth/authorize”);
Hi Lorenz,

I got fixed one issue related to posting the tweet. The reason for twitter posting failed is due to app registration in dev.twitter.com which is in read only mode. I updated it to read and write mode which cleared the problem.It worked for me if it is not relevant pls ignore.

Are you getting error code 403 (with duplicate message error)? If your app is sending the same message as in a previous post, try changing the message.
can some one post the full code of this?
can some one post full code of this?
https://github.com/lorensiuswlt/AndroidTwitter
hey lorenze
some fatal expression is showing up and i cant figure it out can u help me with that
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);
THANK U VERY MUCH FOR YOUR POST … i AM TRYING TO RELOGIN INTO TWIITTER FROM 6 MONTHS ………… BUT WHOMEVER I ASK THEY JUST SAY ONE SIMPLE THING IN TWITTER THERE IS SINGLE SIGN IN ON SO U CANNOT RELOGIN AGAIN AND ALSO ONCE YOU HAVE LOGGED IN YOU CANNOT LOGOUT.

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,
Could you give the log cat error message for more detail?

———————————–
Pls solve this,
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 Ramesh, thanks for that trick..thats the right way to solve the problem.
i have same problem that RubyD have.. i have also try the way Ramesh told to make a libs folder and paste all jar packages into it. but error is same on mTwitter on create(Bundle). in TestConnect class.. my logs are

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.

Hi joseph, try to use https instead of http when accessing request token
https://twitter.com/oauth/request_token
I tried to update it but no luck.
Still it doesnt work. Thanks anyway
I’ve set:
REQUEST_TOKEN = “https://api.twitter.com/oauth/request_token”;
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?
Thanks in advance…

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 Lorenz,
I installed your app in my android galaxy y.version 2.3.3.every authorization is done perfectly .when i post a tweet.i m getting a toast that the tweet is posted..but when i check my twitter account..there is no tweet could u help me out

Hi, i’ll update the code soon..;)
i want ask with your code, will access token be expired although user has been login and not logout?and if yes, how to make access token again without login again.
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 try to resolve my problem. I think “TwitterApp.java” not work correctly. I’ll got error when execute “TwitterApp.java”
Help me, Lorenz.
I am getting “Twitter connection failed” error while executing this function:
mTwitter.authorize();
in simulator as well as in device i am getting this error. i have all config jar files and also keys.
Excuse me: how to release the twitter with image?For twitter API 1.1, your code is still valid?
我英语不好，直接用汉语表达吧！在android app怎么发布带有图片的状态（推文）呢？
private TwitterApp mTwitter;
I got error on that…what can i do???
I had done all the steps which stated above but wen i click connect it shows that twitter connection failed.. can anyone help me out wat mistake i had done…
Hello suresh,

Get “Error getting request token” every time. Consumer key and consumer secret are correct!
I found solution for this problem. Developer must enter request url on dev.twitter.com.
i downloaded the code but i’m unable to authroize. when i click on authorize button it redirects me back to first screen and toast a login failed how can i login and post a tweet
The example helped alot . thanks for posting the code…..
How do you log out the user from twitter?
Don’t need to logout, there is no api for logging out. Just clear the saved access token and webview cache.
