I've been stuck for days looking for a simple tutorial on making a facebook wall post with an icon or image and some text using the graph API. I've tried countless tutorials and they all seem very complicated and I can't get them to work. Even the samples that come with the SDK do not create sessions.
I have been sucessful in setting up the SDK and getting my APP_ID all that is left is the Java code for a custom button to share my app on the users wall.
You can post image on Facebook in two different ways. If you want to post a picture from a URL, you can post it as below:
Bundle parameters = new Bundle();
parameters.putString("description","your description/message");
parameters.putString("link", "your link");
parameters.putString("name", "Name of your application/ any name you want to post");
// parameters.putString("caption", " caption if any!");
parameters.putString("picture", "Link to your image");
try
{
facebook.request("me");
response = facebook.request("me/feed", parameters, "POST");
Log.d("Tests", "got response: " + response);
}
catch (Exception e)
{
e.printStackTrace();
}
or if you want to post an image from SD card, you can create a Bitmap from the image you want to post and then convert it into ByteArray and post it as below:
Bundle parameters = new Bundle();
Log.e("byte array", ""+mByteArray);
parameters.putString("message", "your message");
parameters.putByteArray("picture", mByteArray);
try
{
facebook.request("me");
response = facebook.request("me/photos", parameters, "POST");
Log.d("Tests", "got response: " + response);
}
catch (Exception e)
{
e.printStackTrace();
}
P.S. The first method is to post image on user's Facebook wall, and the latter is for uploading picture with message in user's photo album on Facebook, which will also be posted as an update!
you can post your image with text from your application in a very simply way.
Call this method while clicking on the button widget say btnImagePostToWall like...
btnImagePostToWall.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
postImageToWall();
}
});
Get Profile information by making request to Facebook Graph API....
public void postImageToWall() {
facebook.authorize(
this,
new String[] { "user_photos,publish_checkins,publish_actions,publish_stream" },
new DialogListener() {
#Override
public void onFacebookError(FacebookError e) {
// TODO Auto-generated method stub
}
#Override
public void onError(DialogError dialogError) {
// TODO Auto-generated method stub
}
#Override
public void onComplete(Bundle values) {
postImageonWall();
}
#Override
public void onCancel() {
// TODO Auto-generated method stub
}
});
}
private void postImageonWall() {
byte[] data = null;
Bitmap bi = BitmapFactory.decodeResource(getResources(),
R.drawable.ic_launcher);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bi.compress(Bitmap.CompressFormat.JPEG, 100, baos);
data = baos.toByteArray();
Bundle params = new Bundle();
params.putString(Facebook.TOKEN, facebook.getAccessToken());
params.putString("method", "photos.upload");
params.putByteArray("picture", data); // image to post
params.putString("caption", "My text on wall with Image "); // text to post
AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(facebook);
mAsyncRunner.request(null, params, "POST", new SampleUploadListener(),
null);
}
Just create a class SampleUploadListener which implements AsyncFacebookRunner.RequestListener...
class SampleUploadListener implements AsyncFacebookRunner.RequestListener {
#Override
public void onComplete(String response, Object state) {
}
#Override
public void onIOException(IOException e, Object state) {
}
#Override
public void onFileNotFoundException(FileNotFoundException e,
Object state) {
}
#Override
public void onMalformedURLException(MalformedURLException e,
Object state) {
}
#Override
public void onFacebookError(FacebookError e, Object state) {
}
}
Hope this will help you a bit.... :-)
here you go. you may have to do some debugging etc, but this worked for me.

I am trying to set text in facebook status from my app, but its not copying in the status dialog box of facebook post dialog box. Dialog box is opening correctly for fb, but message is not copied in the status box. Thanks
My code is :
facebook = new Facebook("my_app_id");
Bundle parameters = new Bundle();
parameters.putString("message", "HI there");
facebook.dialog(this, "feed", parameters,
new PostDialogListener());
PostDialogListener class
public class PostDialogListener implements DialogListener {
#Override
public void onFacebookError(FacebookError e) {
e.printStackTrace();
}
#Override
public void onComplete(Bundle values) {
final String postId = values.getString("post_id");
if (postId != null) {
} else {
}
}
#Override
public void onError(DialogError e) {
e.printStackTrace();
}
#Override
public void onCancel() {
}
}
Try this code and see if it does the job for you. For me it works perfectly because i want to post a custom message.
new Thread(){
public void run(){
Looper.prepare();
Bundle parameters = new Bundle();
parameters.putString("message", "your_message_here");
parameters.putString("caption", "your_caption");
try {
mFacebook.request("me");
String response = mFacebook.request("me/feed", parameters, "POST");
Log.d("Tests", "got response: " + response);
if (response == null || response.equals("")
|| response.equals("false") || response.startsWith("{\"error\"")) {
mActivity.runOnUiThread(failRunnable);
} else {
mActivity.runOnUiThread(successRunnable);
}
} catch (Exception e) {
showToast("Failed to post to wall!");
e.printStackTrace();
}
}
}.start();
mFacebook is my Facebook Object.
I'm having trouble setting up a simple facebook wall post to the user's wall.
I want a facebook dialog box to pop up on clicking a button with a thumbnail, description and title.
I have tried the following code but no dialog box pops up:
shareOnFacebookBtn.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
/*
* Get existing access_token if any
*/
mPrefs ShopDetailActivity.this.getActivity().getPreferences(Context.MODE_PRIVATE);
String access_token = mPrefs.getString("access_token", null);
long expires = mPrefs.getLong("access_expires", 0);
if(access_token != null) {
facebook.setAccessToken(access_token);
}
if(expires != 0) {
facebook.setAccessExpires(expires);
}
/*
* Only call authorize if the access_token has expired.
*/
if(!facebook.isSessionValid()) {
facebook.authorize(ShopDetailActivity.this.getActivity(),new String[] { "publish_stream" }, new DialogListener() {
#Override
public void onComplete(Bundle values) {
SharedPreferences.Editor editor = mPrefs.edit();
editor.putString("access_token", facebook.getAccessToken());
editor.putLong("access_expires", facebook.getAccessExpires());
editor.commit();
//facebook.dialog(ShopDetailActivity.this.getActivity(), "feed", new SampleDialogListener());
Bundle parameters = new Bundle();
parameters.putString("message", "message");// the message to post to the wall
facebook.dialog(context, "feed", parameters, this);
}
#Override
public void onFacebookError(FacebookError error) {}
#Override
public void onError(DialogError e) {}
#Override
public void onCancel() {}
});
}
}
});
The authorize window opens and after clicking allow I'd expect the dialog box to pop up but it just returns to the app.
What am I doing wrong?
facebook = new Facebook("your facebook id");
mAsyncRunner = new AsyncFacebookRunner(facebook);
facebook.authorize(this, new String[]
{ "publish_stream", "offline_access" }, -1,
new DialogListener()
{

{

}

{
}
public void onError(DialogError e)
{
}

{
}
});
//add method into your class

{
if (fb != null)
{
if (fb.isSessionValid())
{
Bundle b = new Bundle();
b.putString("picture", your image url);

"description",

Log.i("Facebook", "Image link submitted.");
}
else
{

Write below two functions into your Activity.
public void postToWall() {
String message="Good Morning to All";
Bundle parameters = new Bundle();
parameters.putString("message", message);
parameters.putString("description", "topic share");
try {
facebook.request("me");

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!");
}
} catch (Exception e) {
showToast("Failed to post to wall!");
e.printStackTrace();
}
}
2)
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();
}
3)
public void loginAndPostToWall() {
facebook.authorize(this, PERMISSIONS, Facebook.FORCE_DIALOG_AUTH, new LoginDialogListener());
}
Write below code into your wall post button click event
facebook = new Facebook(APP_ID);
restoreCredentials(facebook);
if (!facebook.isSessionValid()) {
loginAndPostToWall();
} else {
postToWall();
}
I made a little example for posting messages to facebook feed via Android app.
It works great but i just want to add more content to the post like the facebook page's icon, a link and more stuff..
How can i add these parameters to my facebook dialog to post them as well?
public class MainActivity extends Activity

Facebook facebook = new Facebook("Here i got my app id.");
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);

// Posting my message, maybe here i could add paramterers like icon and a link etc..?
facebook.dialog(MainActivity.this, "feed", new PostDialogListener());
}

}
