Adding Facebook integration to an Android application
Introduction
This tutorial describes how to integrate an Android application with Facebook. We are going to authenticate using OAuth and publish a wall post on Facebook from an Android application. We will be using the Facebook Android SDK to do this.
This article is aimed at Android developers.
UPDATE Dec 04, 2011: The last couple of months there were quite some changes to the Facebook API and the Android Facebook SDK that deprecated the code in this tutorial. The “stream_publish” event was deprecated in favour of the graph API(“me/feed”) and the Facebook class from the SDK needs an app_id in its constructor now(before, it didnt and the app_id needed to be passed every time to the Facebook.authorize and Facebook.request methods). I updated the tutorial below so it is up to date again.
Context
We will implement a ShareOnFacebook activity, which will be usable standalone, and will be callable from code like:
Intent postOnFacebookWallIntent = new Intent(this, ShareOnFacebook.class); postOnFacebookWallIntent.putExtra("facebookMessage", "is integrating stuff again."); startActivity(postOnFacebookWallIntent);
This will result in a Facebook wallpost like this:
Getting an application id from Facebook
First of all, you will need a Facebook application id. To get one, you need a facebook account first, login to that account and go to http://www.facebook.com/developers. After granting permission to the Developer app, there will be a button “Setup new application” available. After pressing this button, you will be asked for the name of your application, after which you will need to provide the application details, as in the following form:
After providing all the details, your app will be added to your (private) “current applications” on Facebook and you will be provided with an application id. Note down that application id somewhere. Note that for now the new app is not yet submitted to Facebook, which is what you want, since it is not finished yet.
The Facebook Android SDK
The facebook website API is always called through http. It will process input parameters and serve response pages/json snippets.
The Facebook Android SDK will wrap these http calls(authenticate, publish wall post,..) in an android dialog box with a webview, and enable developers to register listeners on certain events for these dialog boxes, such as unsuccesful and succesful authentication. That way, it becomes quite easy to integrate the http api in a native android application.
You can get it at http://github.com/facebook/facebook-android-sdk/ through “Downloads”. From the resulting downloaded zip file, add everything under facebooksrc to your own source folder.
ShareOnFacebook activity
Below is the complete source code for our activity. For some people, this will probably be the only interesting part.
public class ShareOnFacebook extends Activity{ private static final String APP_ID = "269876589726953"; private static final String[] PERMISSIONS = new String[] {"publish_stream"}; private static final String TOKEN = "access_token"; private static final String EXPIRES = "expires_in"; private static final String KEY = "facebook-credentials"; private Facebook facebook; private String messageToPost; public boolean saveCredentials(Facebook facebook) { Editor editor = getApplicationContext().getSharedPreferences(KEY, Context.MODE_PRIVATE).edit(); editor.putString(TOKEN, facebook.getAccessToken()); editor.putLong(EXPIRES, facebook.getAccessExpires()); return editor.commit(); } public boolean restoreCredentials(Facebook facebook) { SharedPreferences sharedPreferences = getApplicationContext().getSharedPreferences(KEY, Context.MODE_PRIVATE); facebook.setAccessToken(sharedPreferences.getString(TOKEN, null)); facebook.setAccessExpires(sharedPreferences.getLong(EXPIRES, 0)); return facebook.isSessionValid(); } @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); facebook = new Facebook(APP_ID); restoreCredentials(facebook); requestWindowFeature(Window.FEATURE_NO_TITLE); setContentView(R.layout.facebook_dialog); String facebookMessage = getIntent().getStringExtra("facebookMessage"); if (facebookMessage == null){ facebookMessage = "Test wall post"; } messageToPost = facebookMessage; } public void doNotShare(View button){ finish(); } public void share(View button){ if (! facebook.isSessionValid()) { loginAndPostToWall(); } else { postToWall(messageToPost); } } public void loginAndPostToWall(){ facebook.authorize(this, PERMISSIONS, Facebook.FORCE_DIALOG_AUTH, new LoginDialogListener()); } public void postToWall(String message){ Bundle parameters = new Bundle(); parameters.putString("message", message); parameters.putString("description", "topic share"); try { facebook.request("me"); String response = facebook.request("me/feed", parameters, "POST"); Log.d("Tests", "got response: " + response); if (response == null || response.equals("") || response.equals("false")) { showToast("Blank response."); } else { showToast("Message posted to your facebook wall!"); } finish(); } catch (Exception e) { showToast("Failed to post to wall!"); e.printStackTrace(); finish(); } } class LoginDialogListener implements DialogListener { public void onComplete(Bundle values) { saveCredentials(facebook); if (messageToPost != null){ postToWall(messageToPost); } } public void onFacebookError(FacebookError error) { showToast("Authentication with Facebook failed!"); finish(); } public void onError(DialogError error) { showToast("Authentication with Facebook failed!"); finish(); } public void onCancel() { showToast("Authentication with Facebook cancelled!"); finish(); } } private void showToast(String message){ Toast.makeText(getApplicationContext(), message, Toast.LENGTH_SHORT).show(); } }
In what follows, we will go through the code step by step.
1. onCreate
In the onCreate method we are restoring the previously stored credentials – if any – from the SharedPreferences of the app. As we will see later, these will be set after succesful authentication.
In the onCreate method we are also setting the view to the following layout xml file:
<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="250dp" android:layout_height="125dp"> <LinearLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_gravity="center" android:padding="5dp" android:layout_alignParentTop="true"> <TextView android:text="Do you want to share this on Facebook?" android:padding="5dp" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_horizontal"/> </LinearLayout> <LinearLayout android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_gravity="center" android:layout_alignParentBottom="true"> <Button android:layout_alignParentBottom="true" android:layout_height="wrap_content" android:id="@+id/FacebookShareButton" android:text="Yes" android:layout_width="120dp" android:layout_gravity="center_horizontal" android:layout_centerHorizontal="true" android:onClick="share" android:layout_margin="2dp" android:padding="5dp"/> <Button android:layout_alignParentBottom="true" android:layout_height="wrap_content" android:id="@+id/FacebookShareNotButton" android:text="No" android:layout_width="120dp" android:layout_gravity="center_horizontal" android:layout_centerHorizontal="true" android:onClick="doNotShare" android:layout_margin="2dp" android:padding="5dp"/> </LinearLayout> </RelativeLayout>
In the AndroidManifest.xml file, we are also specifying the activity as:
<activity android:name=".ShareOnFacebook" android:label="@string/app_name" android:screenOrientation="portrait" android:theme="@android:style/Theme.Dialog">
so our activity will be displayed as a dialog box, showing as:
Obviously, when the “No” button is clicked, nothing fancy happens – the activity just finishes. More interesting is the “Yes” button though, which will execute the share method on our activity.
2. share
This share method is implemented as:
public void share(View button){ if (! facebook.isSessionValid()) { loginAndPostToWall(); } else { postToWall(messageToPost); } }
So, if our session is not valid(if we dont have a token or the token is expired, the isSessionValid method will fail, so the user will initiate the login process again), the user will be asked to login to facebook, give the app the necessary permissions and authorize the wallpost. If the session is valid, the user will only be asked to authorize the wallpost. We will assume the user is not logged in yet. The second scenario is just a subset of the first one.
3. loginAndPostToWall
This method consists of just one line:
facebook.authorize(this, PERMISSIONS, Facebook.FORCE_DIALOG_AUTH, new LoginDialogListener());
This method call will present the following dialog box on the left to the user:
after, if the user logs in succesfully, he will be asked to give permission to this app to post to his wall, as shown in the right part of the pic.
Notice how the facebook android api allows us to add custom listeners for certain events, in this case all events related to authentication.
EDIT: If the Facebook app is installed on the phone, the Facebook.FORCE_DIALOG_AUTH parameter makes sure authentication is forced. Without it, all the above will result in an endless spinning wheel, because the app keeps waiting on a login dialog but never gets it.
The implementation of our custom listener looks like this:
class LoginDialogListener implements DialogListener { public void onComplete(Bundle values) { saveCredentials(facebook); if (messageToPost != null){ postToWall(messageToPost); } } public void onFacebookError(FacebookError error) { showToast("Authentication with Facebook failed!"); finish(); } public void onError(DialogError error) { showToast("Authentication with Facebook failed!"); finish(); } public void onCancel() { showToast("Authentication with Facebook cancelled!"); finish(); } }
So, in case of failure, we will show the user a notification of the failure and finish the activity. In case of succesful authentication we are storing the credentials in the shared preferences of the application, and we are posting the message to the wall through the postToWall method.
4. postToWall
Before, the following dialog box used to be presented to the user:
But when using the new Graph API(“me/feed”), the message is directly sent through and posted to the user’s wall, without asking for confirmation.
Our method is a bit longer than the previous one:
Bundle parameters = new Bundle(); parameters.putString("message", message); parameters.putString("description", "integrating stuff"); try { facebook.request("me"); String response = facebook.request("me/feed", parameters, "POST"); Log.d("Tests", "got response: " + response); if (response == null || response.equals("") || response.equals("false")) { showToast("Blank response."); } else { showToast("Message posted to your facebook wall!"); } finish(); } catch (Exception e) { showToast("Failed to post to wall!"); e.printStackTrace(); finish(); }
hey thanks for such nice and easy code..

LikeDislikeI have a question…
How can I post on wall directly from my application code..
I don’t want to wright manually to publish on my wall
Was this answer helpful?
LikeDislikeThe account owner still needs to approve the post if you are going to use the SDK, so there is no way to directly publish from code as far as I know.
The best thing is probably to use an action as in the above post, which takes care of the Facebook SDK details for you, but still goes through the login and approve pages of Facebook itself.

ohh ic.
I’m making android game app right now,
I think if that’s the case, then the players could change the score (my plan is, the real score automatically posted)
thx for providing the tutorial anyway

LikeDislikeHi, thanks for the great tutorial.
Is there a way to post a status on Facebook without user interaction on the last dialog? I.e. facebook.dialog(…) shows dialog on which the user should press Publish to add the status on his wall. I want to skip this part and to publish the message right after the authentication.
Thanks!

LikeDislikeThe thing is that when you put Unicode (UTF) text as message, i.e. some special characters, it sets then scrambled in the dialog, but nice on the wall, just wanna fix this.

but I’ve got some problem while making the request using your codes…
cause everytime i launch the activity, the facebook layout window just pop in a sec and then finish…
it’s seems like my facebook app interupting the sdk(i don’t know really),
cause when i remove my facebook app, your code works and I can post new message on my wall…
I hope you can find the solution for this…
Thank you

LikeDislikePut this in the class and it should work:
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
facebook.authorizeCallback(requestCode, resultCode, data);
}
facing some issues.. however all resolved except one..shareonfacebook activity has a method call facebook.authorize(this, APP_ID, PERMISSIONS, new LoginDialogListener()); on point 3 u have discussed.
but method with these signatures is not available in Facebook.java..
Kindly reply soon also on my id mentioned mca730@gmail.com

LikeDislikeIt seems that an update has managed to mess up something. Was working great but now the Post Message txtbox is now blank and the text sent to it never makes it there. This started occuring somewhere between 8/1/2011 and 8/5/2011.
Was this answer helpful?
LikeDislikeYep, the message parameter cant be passed to the stream_publish event anymore since around that time. We need to use the me/feed event now to be able to do the same.
Hi friends ,
I am not so experienced in coding as of now. I have a task to work on. I have followed the procedure mentioned here. I am getting error in few places in my code. I just wanted to discuss these:
<> Initially I have copied the layout mentioned in this page into the my default main.xml in my project.
Line 53 :
setContentView(R.layout.facebook_dialog);
I am receiving an error here as there is no such layout present. Do I pull the layout mentioned above i this page? Could some one clarify?
<> Line 75:
facebook.authorize(this, APP_ID, PERMISSIONS, new LoginDialogListener());
I get an error at "authorize" in above line. what am I missing.
private static final String APP_ID = "changedtomyappID";
private static final String[] PERMISSIONS = new String[] {"publish_stream"};
private static final String TOKEN = "access_token";
private static final String EXPIRES = "expires_in";
private static final String KEY = "facebook-credentials";
Please let me know what am I missing out. Any resolution would be of really great help to me.
Thanks
Ashwin

LikeDislikeHi, I have this error which is
Description Resource Path Location Type
The method authorize(Activity, String[], int, Facebook.DialogListener) in the type Facebook is not applicable for the arguments (AnotherTestActivity, String[], String, AnotherTestActivity.LoginDialogListener) AnotherTestActivity.java /Integration/src/another/test line 71 Java Problem
How do you solve it?
Was this answer helpful?
LikeDislikeHi qwerty, this is because the old tutorial used an old version of the Android Facebook SDK. In the new one the APP_ID needs to be passed to the Facebook class constructor, and cant/doesnt need to be passed anymore in the authorize and request methods. Hence, there is no authorize(Activity, String[], int, Facebook.DialogListener) method anymore.

LikeDislikeI seem to have the same problem as DK, the textbox is blank, despite the text is transferred correctly to the activity. Does anybody out there have a fix ? It would be highly appriciated.

LikeDislikeHi Pankaj, I had the same – the message not appearing in the box. This is because the “stream_publish” API event was deprecated in favour of the Graph API. You should use “me/feed” now.

LikeDislikeHi Mikkel, this is because we cant pass the “message” parameter anymore to the stream_publish event. We have to use “me/feed” now.

LikeDislikeThank for this nice code. I can’t post anything to facebook, I just got an empty “Post To Wall” dialog, but my message is not passed along to the dialog
Any ideas ??
Hey Leo, yes, me and some others had the same problem. This is because the “stream_publish” event got deprecated. They seem to be still keeping it to show the dialog and everything, but you definitely cant pass it the message parameter anymore. We have to use “me/feed” now.

LikeDislikeHEy thanx for the tutorial.
Seems to work.
When I push the yes button on the dialog I see it opening facebook but then it gives me the same dialog again could this be because my internet connection ist to slow?

LikeDislikeIn your intent in the beggining you wrote :
Intent postOnFacebookWallIntent = new Intent(this, ShareOnFacebook.class);
facebookIntent.putExtra(“facebookMessage”, “is integrating stuff again.”);

is facebookIntent postOnFacebookWallIntent? or is it me not understanding the code?

I am doing exactly as above but i am not able to execute and giving you log cat stack trace please help me out.Thanks in advance..

Just replace the code of the “postToWall” method with the accepted solution and it will work like a charm, you will be able to post a message in facebook’s wall.

LikeDislikeHello mister,
It seems that having the Facebook app from android Market installed on device/emulator creates the problem that David and Ranjeet experienced.
Having the Facebook app installed I get the dialog over and over again and the application does not post anything on my wall
Uninstalling the Facebook applications solved the problem
Is there any solution that ShareOnFacebook to work with Facebook application installed? I’m asking this because there are lots of users that have the application installed
Was this answer helpful?
LikeDislikeI was able to reproduce this. I had the same problem after I updated my Facebook app(I didnt update it for a few months on my Android device).
Basically, the Facebook app seems to intercept the authentication but never passes control again to the app. I think it is an issue with the current Facebook SDK/Facebook app.
There are more people having this problem: http://stackoverflow.com/questions/5960224/post-to-user-facebook-wall-not-working-when-facebook-app-is-installed-on-device and some sdks that are built on top of the Android Facebook SDK, such as the Socialize SDK, appear to have the same problem.
You can check whether the Facebook app is installed on the device by adding this method:
public boolean isFacebookAppInstalled(){
try{
ApplicationInfo info = getPackageManager().getApplicationInfo(“com.facebook.katana”, 0 );
return true;
} catch( PackageManager.NameNotFoundException e ){
return false;
}
}
and go from there. Maybe use the following when the Facebook app is installed:
Intent sendShareIntent = new Intent(Intent.ACTION_SEND);
sendShareIntent.setClassName(“com.facebook.katana”, “com.facebook.katana.ShareLinkActivity”);
sendShareIntent.setType(“text/plain”);
sendShareIntent.putExtra(Intent.EXTRA_TEXT, messageToPost);
startActivity(sendShareIntent);
but the problem with this code is the EXTRA_TEXT has to contain an url. Plain text does not work. In an app of my own I used this method, but I ended up appending a link to the app’s homepage to every message.

LikeDislikeHi I Found a solution for your problem see here
public void loginAndPostToWall() {
facebook.authorize(PostwallActivity.this, PERMISSIONS,new LoginDialogListener());
}
previously tour using this for login replace this line to
public void loginAndPostToWall() {
facebook.authorize(PostwallActivity.this, PERMISSIONS,Facebook.FORCE_DIALOG_AUTH,new LoginDialogListener());
}
you got a optput and get your app login page only but not a main facebook app login page. i Think it is use full for u.

this code is working if the official facebook app is not installed on the phone.
This code does not use the SSO solution of facebook. I dont get it running by my own. Can someone provide an explanation how it should work with sso and facebook app installed.
Hello, you need to replace the line
facebook.authorize(this, PERMISSIONS, new LoginDialogListener());
with
facebook.authorize(this, PERMISSIONS, Facebook.FORCE_DIALOG_AUTH, new LoginDialogListener());
to make it work when the Facebook app is installed.

LikeDislikeHi.. Thanks for this post. It has helped me a lot. I am having a small problem though. I was developing an app and I used your code to successfully implement “post on facebook” feature. I had tested it many times on an actual device and it was always successful. Now the app is published. I tried downloading the app and then tried using this feature. Unfortunately, it does not work. I am using Eclipse. Do we need to make any changes in the code before publishing the app like using a different key etc..? I fail to understand what went wrong the moment I published the app. Please help.

LikeDislikeHi Steffen, first of all thanks for your post, it really help me out.
So after lots of problems I finally can run the program, but now i don’t know where do I have to make the call (That context part tree-line-code) cause my program is mostly about xml pages, so I can’t use the java script.
Should i make a java file with just that code and then make a call from the xml file to open that java file? How can I make that?
I really appreciate your help, thanks for all.

LikeDislikeGood tutorial think I almost have it working although not quite.
Firstly I get a lot of these statements in the log:
03-29 16:17:46.503: W/Bundle(17069): Key access_token expected byte[] but value was a java.lang.String. The default value was returned.
03-29 16:17:46.513: W/Bundle(17069): Attempt to cast generated internal exception:
03-29 16:17:46.513: W/Bundle(17069): java.lang.ClassCastException: java.lang.String
03-29 16:17:46.513: W/Bundle(17069): at android.os.Bundle.getByteArray(Bundle.java:1305)
03-29 16:17:46.513: W/Bundle(17069): at com.facebook.android.Util.openUrl(Util.java:161)
03-29 16:17:46.513: W/Bundle(17069): at com.facebook.android.Facebook.request(Facebook.java:751)
Don’t think they harm. But why are they there? It is as if it expects the bundle to contain byte[] instead of Strings but I tried changing it and it complained more about that.
Secondly: I think my post goes through. I get the toast that says it went through. I get this in the log:
03-29 16:17:05.673: D/Tests(17069): got response: {“id”:”698901756_10150775129091757″}
And if I try and do it again I get:
03-29 16:17:48.023: D/Tests(17069): got response: {“error”:{“message”:”(#506) Duplicate status message”,”type”:”OAuthException”,”code”:506}}
So looks like the first post went through. However I don’t see it anywhere on the wall… Any ideas?

LikeDislikeI would like to ask some problem
I input my facebook account after I run it.
But It is not necessary to input my account when I use it again.
How can I input the facebook account again because I want to allow the user to post their message on different facebook if the user has at least one facebook account.(Now I am using the eclipse to run,but I cannot input the different facebook account when I run the code again and It will post the message on my the first facebook account directly.

LikeDislikeNice post,
anyway using sdk higher than 11 an exception will be thrown.
Replace postToWall() method with these lines to be compatible with HoneyComb
or a NetworkOnMainThreadException will be raised
I use an extension of AsyncTask to post the message
public void postToWall(String message) {
FacebookPoster fp = new FacebookPoster();
fp.execute(message, null, null);
}
private class FacebookPoster extends AsyncTask {
@Override
protected String doInBackground(String… message) {
Bundle parameters = new Bundle();
parameters.putString(“message”, message[0]);
parameters.putString(“description”, “topic share”);
try {
facebook.request(“me”);
String response = facebook.request(“me/feed”, parameters, “POST”);
Log.d(“Tests”, “got response: ” + response);
if (response == null || response.equals(“”)
|| response.equals(“false”)) {
return “Blank response.”;
} else {
return “Message posted to your facebook wall!”;
}
} catch (Exception e) {

But I have one questions here. After the successful login, if the user goes to web and revokes the access for this app, How do we handle it in Andorid code? I tried to see if there will be any error (i mean it returns false) in facebook.isSessionValid() but it still returns true but the posting fails. How can we handle this???
Was this answer helpful?
LikeDislikeThanks for the code. It is great, but in latest devices, it is giving android.os.NetworkOnMainThreadException
To resolve this, change the postToWall function to the one below
public void postToWall(String message)
{
new PostMessage().execute(message);
}
then copy the code below into the class
class PostMessage extends AsyncTask
{
int check = 0;
@Override
protected Void doInBackground(String… params) {
String message = params[0];
Bundle parameters = new Bundle();
parameters.putString(“message”, message);
parameters.putString(“description”, “topic share”);
try {
facebook.request(“me”);
String response = facebook.request(“me/feed”, parameters, “POST”);
Log.d(“Tests”, “got response: ” + response);
if (response == null || response.equals(“”) ||
response.equals(“false”)) {
check = 0;
}
else {
check = 1;
}
//finish();
} catch (Exception e) {
check = 2;
e.printStackTrace();
}
return null;
}
@Override
protected void onPostExecute(Void result) {
// TODO Auto-generated method stub
super.onPostExecute(result);
if(check == 0)
{
showToast(“Blank response.”);
}
else if(check == 1)
{
showToast(“Message posted to your facebook wall!”);
}
else if(check == 2)

LikeDislikeHi there,
I had to do a minor adjustment that I want to share with others: on the postToWall, if the user revokes access to the app on FB, the Android App, as it is, never realizes it. So, I had to add this to the method:
else if(response.indexOf(“OAuthException”) != -1){
Log.i(Globals.INFO_TAG, “Error posting to facebook: ” + response);
// Needs to revalidate
try{
facebook.logout(this);
SharedPreferences.Editor editor = getApplicationContext().getSharedPreferences(KEY, Context.MODE_PRIVATE).edit();
editor.putString(TOKEN, “”);
editor.putLong(EXPIRES, 0);
editor.commit();
}catch(Exception ex){
Log.e(Globals.INFO_TAG, “Error login out of FB: ” + ex.toString());
}
showToast(“There was an error while sharing to Facebook. Try again later.”);
}
else {
showToast(“Route posted to your facebook wall!”);
}
That way, the user can grant access again on a later attempt.
