Android how to post picture to friend's wall with facebook android sdk

We can post to facebook friend's wall a text message, but how can we post an image, a picture to a friend's wall using Android Facebook SDK?
When I print out the wall variable it does show correctly USER_ID/feed. After posting the onComplete function of the RequestListener does get called, but there is nothing posted to the friends wall.
Here's example code we're trying to use:
Bundle params = new Bundle();
params.putString("method", "photos.upload");
params.putString("caption", photoCaption.getText().toString());
params.putByteArray("picture", data);
AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(facebook);
String wall = null;
wall = fArray.getJSONObject(pos).getString("id").toString() + "/feed";
mAsyncRunner.request(wall, params,"POST", new RequestListener(){
public void onComplete(String response, Object state) {
Log.d("text","facebook post complete");
}
public void onIOException(IOException e, Object state) {
Log.d("text","facebook post onIOException");
}
public void onFileNotFoundException(FileNotFoundException e, Object state) {
Log.d("text","facebook post onFileNotFoundException");
}
public void onMalformedURLException(MalformedURLException e, Object state) {
Log.d("text","facebook post onMalformedURLException");
}
public void onFacebookError(FacebookError e, Object state) {
Log.d("text","facebook post error");
}
}, null);
This is how I get the list of friends:
AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(facebook);
mAsyncRunner.request("me/friends", new RequestListener(){
public void onComplete(String response,Object state) {
try {
jObject = new JSONObject(response);
fArray = jObject.getJSONArray("data");

This is the method i use to post a picture to a wall, it posts a pic from a URL but you can change it to put a byte[] for the pic instead. The message appears above the picture and the caption appears to the right of the picture.
protected void postPicToWall(String userID, String msg, String caption, String picURL){
try {
if (isSession()) {
String response = mFacebook.request((userID == null) ? "me" : userID);
Bundle params = new Bundle();
params.putString("message", msg);
params.putString("caption", caption);
params.putString("picture", picURL);
response = mFacebook.request(((userID == null) ? "me" : userID) + "/feed", params, "POST");
Log.d("Tests",response);
if (response == null || response.equals("") ||
response.equals("false")) {
Log.v("Error", "Blank response");
}
} else {
// no logged in, so relogin
Log.d(TAG, "sessionNOTValid, relogin");
mFacebook.authorize(this, PERMS, new LoginDialogListener());
}
}catch(Exception e){
e.printStackTrace();
}
}
EDIT:
To post a byte[] rather than a url to a pic then replace the line
params.putString("picture", picURL); with
params.putByteArray("picture", getIntent().getExtras().getByteArray("data"));
where data is your array.

Using bundle method.
Bundle params = new Bundle();
params.putString("message", "Test Post from karthick");
params.putString("caption", "Karthick kumar");
params.putString("name", "Hai Dude");
**params.putString("icon", "http://www.facebook.com/images/icons/default_app_icon.gif");**
params.putString("source", link);
And Then Use...
mAsyncRunner.request(wall, params,"POST", new RequestListener());

Post text to Facebook Wall

Im develop a app to post a simple text to facebook.here is the code I'm using..
Bundle parameters = new Bundle();
parameters.putString("message", msgWillPost);
response = mFacebook.request("me/feed", parameters, "POST");
it work... but the problem I'm facing now is when the "msgWillPost" length too longer, then it will return error. here is the error:
{"error":{"type":"OAuthException","message":"(#1) An unknown error occurred"}}
which I get return from response.
May I konw isn't Facebook request have any limit character to post? or it was other issue. Thank you.
P/S: sorry about my english hope u guys understand what I'm talking about.
Thanks.

}
} catch(Exception e) {

}
add permission in authorize method

I know status updates must be less than 420 characters. Have you tried 419 characters to make sure that post succeeds?
If this is really the issue (which is weird that the error message isn't very helpful), then you'll probably want to do input validation in your app prior to posting to Facebook.

Why does my android facebook sdk give a

i am trying to publish something on my wall. i am using this code, called by OnClickListener of a Button
public void postOnWall(String msg) {
mFacebook.authorize(this,new String[] {"publish_stream", "read_stream", "offline_access"},
new DialogListener() {
public void onError(DialogError e) {
}
public void onFacebookError(FacebookError e) {
}
public void onCancel() {
}
public void onComplete(Bundle values) {
}
}
);
Log.d("Tests", "Testing graph API wall post");
try {
Bundle parameters = new Bundle();
parameters.putString("message", msg);
parameters.putString("description", "test test test");
String response = mFacebook.request("me/feed", parameters,
"POST");
Log.d("Tests", "got response: " + response);
if (response == null || response.equals("") ||
response.equals("false")) {
Log.v("Error", "Blank response");
}
} catch(Exception e) {
e.printStackTrace();
}
}
The response string however reads
{"error":{"type":"OAuthException","message":"An active access token must be used to query information about the current user."}}
Also, the Dialog that should be requesting permissions never stays. it starts loading, but then dissapears.

It seems like you haven't properly authenticated the user.
I'm not sure if you just left out that part of your code or you're not doing it at all but I would take a look at the example provided with the API.

Android: How to post update on Facebook wall automatically?

I want my android application to automatically post a preset message when the user click on a button. The preset message will be set by the user, so I am guessing that is not a violation of Facebook policies. How do I do this?

private static final String[] PERMISSIONS =
new String[] {"publish_stream", "read_stream", "offline_access"};
Facebook authenticatedFacebook = new Facebook(APP_ID);
postButton.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
authenticatedFacebook.authorize(Tests.this, PERMISSIONS,
new TestPostListener());
}
});
public class TestPostListener implements DialogListener {
public void onComplete(Bundle values) {
try {
Log.d("Tests", "Testing request for 'me'");
String response = authenticatedFacebook.request("me");
JSONObject obj = Util.parseJson(response);
Log.d("Tests", "Testing graph API wall post");
Bundle parameters = new Bundle();
parameters.putString("message", "Amit Siddhpura");
parameters.putString("description", "Hi Mr. Amit Siddhpura");
response = authenticatedFacebook.request("me/feed", parameters,
"POST");
Log.d("Tests", "got response: " + response);
} catch (Throwable e) {
e.printStackTrace();
}
}
public void onCancel() {
}
public void onError(DialogError e) {
e.printStackTrace();
}
public void onFacebookError(FacebookError e) {
e.printStackTrace();
}
}

You have to create Application on Facebook
And get authenticate from user, then you can get a access_token to post some message through Graph API
I think your application have to request extended permissions : publish_stream, offline_access
There is Facebook-Android-SDK source code on github, you can refer it.

Post on Facebook wall using Facebook Android SDK without opening dialog box

Using the Facebook SDK, I can login and store my access_token into a database. When I try to create a post, the Facebook wall is still empty on both my phone and emulator due to these problems:
1) I fetch an access_token from the database and pass the access_token to Facebook, but I'm not allowed to post on a wall.
2) I cannot post my message without opening a dialog box.
mPostButton.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
String message = "Post this to my wall";
Bundle params = new Bundle();
params.putString("message", message);
mAsyncRunner.request("me/feed", params, "POST", new WallPostRequestListener());
}
});
public class WallPostRequestListener extends BaseRequestListener {
public void onComplete(final String response) {
Log.d("Facebook-Example", "Got response: " + response);
String message = "<empty>";
try {
JSONObject json = Util.parseJson(response);
message = json.getString("message");
} catch (JSONException e) {
Log.w("Facebook-Example", "JSON Error in response");
} catch (FacebookError e) {
Log.w("Facebook-Example", "Facebook Error: " + e.getMessage());
}
final String text = "Your Wall Post: " + message;
Example.this.runOnUiThread(new Runnable() {
public void run() {
mText.setText(text);
}
});
}
}
How can I post to Facebook without opening the dialog box?

i applied following code and could successfully posted my message on wall.
public void postOnWall(String msg) {
Log.d("Tests", "Testing graph API wall post");
try {
String response = mFacebook.request("me");
Bundle parameters = new Bundle();
parameters.putString("message", msg);
parameters.putString("description", "test test test");
response = mFacebook.request("me/feed", parameters,
"POST");
Log.d("Tests", "got response: " + response);
if (response == null || response.equals("") ||
response.equals("false")) {
Log.v("Error", "Blank response");
}
} catch(Exception e) {
e.printStackTrace();
}
}

I updated my tutorial at http://www.integratingstuff.com/2010/10/14/integrating-facebook-into-an-android-application/ and it is now exactly answering this question.
It is based on and basically the same as Ankit's answer, but guides people from start to finish through implementing the whole process.

Well it's not that something gets posted on wall without informing user. When user allows your application, then the Android Facebook sdk presents another page, where there is a text that your applications sends, and a textBox where user can write on his wall, similar to the screenshot i have attached
The actual layout on mobile device is slightly different, but it's in the same format. This process is well shown in the sample examples of facebook android sdk.
Now check the question asked in this post:
Facebook Connect Android -- using stream.publish # http://api.facebook.com/restserver.php'>Facebook Connect Android -- using stream.publish # http://api.facebook.com/restserver.php
In that question look for these : postParams.put(), similar type of lines will be there in some of your JAVA files. These are the lines using which you can post the data to Facebook.
For example:
postParams.put("user_message", "TESTING 123");
is the message,
postParams.put("attachment", "{\"name\":\"Facebook Connect for Android\",\"href\":\"http://code.google.com/p/fbconnect-android/\",\"caption\":\"Caption\",\"description\":\"Description\",\"media\":[{\"type\":\"image\",\"src\":\"http://img40.yfrog.com/img40/5914/iphoneconnectbtn.jpg\",\"href\":\"http://developers.facebook.com/connect.php?tab=iphone/\"}],\"properties\":{\"another link\":{\"text\":\"Facebook home page\",\"href\":\"http://www.facebook.com\"}}}");
is the line where you are providing icon for application, description,caption, title etc.

I used Ankit's code for posting on facebook wall but his code give me error android.os.NetworkOnMainThreadException.
After searching on this problem a solution told me that put your code in AsyncTask to get rid out of this problem. After modified his code it's working fine for me.
The modified code is looks like:
public class UiAsyncTask extends AsyncTask<Void, Void, Void> {
public void onPreExecute() {
// On first execute
}
public Void doInBackground(Void... unused) {
// Background Work
Log.d("Tests", "Testing graph API wall post");
try {
String response = facebook.request("me");
Bundle parameters = new Bundle();
parameters.putString("message", "This test message for wall post");
parameters.putString("description", "test test test");
response = facebook.request("me/feed", parameters, "POST");
Log.d("Tests", "got response: " + response);
if (response == null || response.equals("") || response.equals("false")) {
Log.v("Error", "Blank response");
}
} catch(Exception e) {
e.printStackTrace();
}
return null;
}
public void onPostExecute(Void unused) {
// Result
}
}

This class helps me for sent messages on my Facebook wall WITHOUT dialog:
public class FBManager{
private static final String FB_ACCESS_TOKEN = "fb_access_token";
private static final String FB_EXPIRES = "fb_expires";
private Activity context;
private Facebook facebookApi;
private Runnable successRunnable=new Runnable(){
#Override
public void run() {
Toast.makeText(context, "Success", Toast.LENGTH_LONG).show();
}
};
public FBManager(Activity context){
this.context = context;
facebookApi = new Facebook(FB_API_ID);
facebookApi.setAccessToken(restoreAccessToken());
}
public void postOnWall(final String text, final String link){
new Thread(){
#Override
public void run(){
try {
Bundle parameters = new Bundle();
parameters.putString("message", text);
if(link!=null){
parameters.putString("link", link);
}
String response = facebookApi.request("me/feed", parameters, "POST");
if(!response.equals("")){
if(!response.contains("error")){
context.runOnUiThread(successRunnable);
}else{
Log.e("Facebook error:", response);
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
}.start();
}
public void save(String access_token, long expires){
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(context);
Editor editor=prefs.edit();
editor.putString(FB_ACCESS_TOKEN, access_token);
editor.putLong(FB_EXPIRES, expires);
editor.commit();
}
public String restoreAccessToken(){
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(context);
return prefs.getString(FB_ACCESS_TOKEN, null);
}
public long restoreExpires(){
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(context);
return prefs.getLong(FB_EXPIRES, 0);
}
}
