invite friends to facebook app - android, no invitations sent

I have created a facebook event with my android coding and now I want to invite friends to it.
Below is my code to invite friends:
private void inviteFriends()
{
try
{
Bundle params = new Bundle();
params.putString("title", "invite friends");
params.putString("message", "come join us!");
facebook.dialog(this, "apprequests", params, new DialogListener() {
#Override
public void onComplete(Bundle values) {}
#Override
public void onFacebookError(FacebookError error) {}
#Override
public void onError(DialogError e) {}
#Override
public void onCancel() {}
public void onComplete(String response, Object state)
{
try
{
JSONObject eventResponse = new JSONObject(response);
//event_id = event.getString("id");
Log.i(TAG, "Event Response => "+eventResponse);
Log.w("myapp", friends);
//Toast.makeText(getApplicationContext(), "New Event Created!!", Toast.LENGTH_LONG).show();
}
catch (Exception e)
{
}
}
});
}
catch (Exception e)
{
}
}
The code works up to selecting friends, the title and message comes with the friend list. I can send the invitation but no notifications are sent to selected people.
Please tell me what needs to be done. Thank you in advance!

Have you turned on the App omn Facebbok Tab in your app developer setting like this.
If don't then it will not sent notification to your friends.

Post Photo to Facebook from Android Application, Photo taken from Android Gallery

I am currently developing an Android Application target build is 4.0 Ice-Cream Sandwich.
So far, I am able to post a normal Text onto Facebook with this code:
public void postToWall() {
// post on user's wall.
facebook.dialog(this, "feed", new DialogListener() {
#Override
public void onFacebookError(FacebookError e) {
}
#Override
public void onError(DialogError e) {
}
#Override
public void onComplete(Bundle values) {
}
#Override
public void onCancel() {
}
});
}
However, I am unable to post a photo onto Facebook with Captions. I've search around online and one of the codes I found is this:
public void postToWall() {
// post on user's wall.
byte[] data = null;
Bitmap bi = BitmapFactory.decodeFile(photoToPost);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bi.compress(Bitmap.CompressFormat.JPEG, 100, baos);
data = baos.toByteArray();
Bundle params = new Bundle();
params.putString("method", "photos.upload");
params.putByteArray("picture", data);
AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(facebook);
mAsyncRunner.request(null, params, "POST", new SampleUploadListener(), null);
}
The problem is, the above code is not working as I don't know whats:
1.photoToPost
2.mAsyncRunner.request keeps giving me an error stating that I cannot put "null" as it is an invalid arguement
3.SampleUploadListener, supposedly is from the FacebookSDK is not working as well (I keep getting an error to create a Class)
Is there a simpler code out here ? Or could someone explain to me the errors I am experiencing.
I am using an "On Click" so far to post normal Text onto Facebook and it points to this method. My goal is to upload a Photo with a Caption onto Facebook.
Thank you all for helping !

1-This is your photo that will be send to wall , it can be an image from your SD card or anywhere else
2-This a class from Facebook SDK , that accepts facebook object (one u created before)
3-This a class from Facebook SDK again
it seems there is something wrong with your Facebook SDK
try to set it again using Right Click on Project >> Properties >> Android and see if library exist or not

The problem lies in following line
mAsyncRunner.request(null, params, "POST", new SampleUploadListener(), null);
you are passing null as graph path this should be like this = "me/feed"
Update
write this line of code
mAsyncRunner.request("me/feed", params, "POST", new SampleUploadListener(), null);
then it should work.

public class CardShared extends Activity{
public static final String APP_ID = "YOUR APP ID";
private Facebook mFacebook;
private AsyncFacebookRunner mAsyncRunner ;
boolean isLoggedIn = false;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// setContentView(R.layout.main);
mFacebook = new Facebook(APP_ID);
mAsyncRunner = new AsyncFacebookRunner(mFacebook);
//Implementing SSO
mFacebook.authorize(this, new String[]{"publish_stream"}, new DialogListener(){
public void onComplete(Bundle values) {
sharePicture(values.getString(Facebook.TOKEN));
Toast.makeText(getApplicationContext(), "Picture Shared Successfully", Toast.LENGTH_SHORT).show();
CardShared.this.finish();
}
public void onFacebookError(FacebookError e) {
Log.d("FACEBOOK ERROR","FB ERROR. MSG: "+e.getMessage()+", CAUSE: "+e.getCause());
}
public void onError(DialogError e) {
Log.e("ERROR","AUTH ERROR. MSG: "+e.getMessage()+", CAUSE: "+e.getCause());
}
public void onCancel() {
Log.d("CANCELLED","AUTH CANCELLED");
}
});
}
//updating Status
public void sharePicture(String accessToken){
byte[] data = null;
try {
Bitmap image = BitmapFactory.decodeResource(getResources(), R.drawable.image_to_be_uploaded);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
image.compress(Bitmap.CompressFormat.JPEG, 100, baos);
data = baos.toByteArray();
Bundle params = new Bundle();
params.putString("method", "photos.upload");
params
.putString(Facebook.TOKEN, mFacebook
.getAccessToken());
params.putByteArray("picture", data);
mAsyncRunner.request(null, params, "POST",
new SampleUploadListener(), null);
} catch (Exception e) {
e.printStackTrace();
}
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Log.d("onActivityResult","onActivityResult");
mFacebook.authorizeCallback(requestCode, resultCode, data);
}
public class SampleUploadListener extends BaseRequestListener {
public void onComplete(final String response, final Object state) {
try {
Log.d("Facebook-Example", "Response: " + response.toString());
JSONObject json = Util.parseJson(response);
final String f = json.getString("src");
} catch (JSONException e) {
Log.w("Facebook-Example", "JSON Error in response");
} catch (FacebookError e) {
Log.w("Facebook-Example", "Facebook Error: " + e.getMessage());
}
}
}
}

put like this
mAsyncRunner.request("me/feed", params, "POST", new SampleUploadListener())

See this link. That will show you how to post image on FaceBook wall as how to post text on wall.
Its good to learn.

Can not access Facebook friends via Android application

I have a problem with accessing the graph API through my android application that retrieves a user's friends as JSONObject, extracts their names and displays them on the screen. It is supposed to be a simple and straightforward task but apparently it is not. When I run my application on Android Nexus I, I login to Facebook, then I am asked I click "Allow" button to grant permissions and I am redirected to a blank page. I am expect to see the name of my friends but it does not happen. Could some one assist me.
public class Login extends Activity
{
Facebook mFacebook = new Facebook("201509899926116");
AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(mFacebook);
String FILENAME = "AndroidSSO_data";
private SharedPreferences mPrefs;
View linearLayout;
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
linearLayout = findViewById(R.id.main_layout);
/* Get existing access_token if any */
mPrefs = getPreferences(MODE_PRIVATE);
String access_token = mPrefs.getString("access_token", null);
long expires = mPrefs.getLong("access_expires", 0);
if(access_token != null)
{
mFacebook.setAccessToken(access_token);
}
if(expires != 0)
{
mFacebook.setAccessExpires(expires);
}
/* Only call authorize if the access_token has expired. */
if(!mFacebook.isSessionValid())
{
mFacebook.authorize(this, new String[] {"user_birthday","email",
"user_relationships","user_religion_politics","user_hometown",
"user_location","user_relationship_details","user_education_history",
"user_likes","user_interests", "user_activities"},
new DialogListener()
{
#Override
public void onComplete(Bundle values)
{
SharedPreferences.Editor editor = mPrefs.edit();
editor.putString("access_token", mFacebook.getAccessToken());
editor.putLong("access_expires", mFacebook.getAccessExpires());
editor.commit();
/* access the graph API */
Log.d("Facebook-Example-Friends Request", "Started API request");
mAsyncRunner.request("me/friends", new FriendsRequestListener());
Log.d("Facebook-Example-Friends Request", "Finished API request");
}
#Override
public void onFacebookError(FacebookError error) {}
#Override
public void onError(DialogError e) {}
#Override
public void onCancel() {}
});
}
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
mFacebook.authorizeCallback(requestCode, resultCode, data);
}
public class FriendsRequestListener implements com.facebook.android.AsyncFacebookRunner.RequestListener
{
/**
* Called when the request to get friends has been completed.
* Retrieve and parse and display the JSON stream.
*/
public void onComplete(final String response)
{
try
{
// process the response here: executed in background thread
Log.d("Facebook-Example-Friends Request", "response.length(): " + response.length());
Log.d("Facebook-Example-Friends Request", "Response: " + response);
final JSONObject json = new JSONObject(response);
JSONArray d = json.getJSONArray("data");
int l = (d != null ? d.length() : 0);
Log.d("Facebook-Example-Friends Request", "d.length(): " + l);
for (int i=0; i<l; i++)
{
JSONObject o = d.getJSONObject(i);
String n = o.getString("name");
String id = o.getString("id");
TextView tv = new TextView(Login.this);
tv.setText(n);
((LinearLayout) linearLayout).addView(tv);
}
}
catch (JSONException e)
{
Log.w("Facebook-Example", "JSON Error in response");
}
}
}
}

I think i might've found the issue.. According to the documentation on onComplet;
/**
* Called when a request completes with the given response.
*
* Executed by a background thread: do not update the UI in this method.
*/
And you are trying to update your UI, so addViews don't actually get reflected on the UI thread.. You should create a method in your activity that you can call from onComplete with runOnUIThread.. Something like this;
runOnUiThread(new Runnable() {
public void run() {
inserFacebookNames(facebookContactNames);
}
});
Let me know if this actually fixes it.. I'm curious if that was the reason..

Android: get facebook friends list

I am using the Facebook SDK to post messages on walls.
Now I need to fetch the Facebook friends list. Can anybody help me with this?
-- Edit --
try {
Facebook mFacebook = new Facebook(Constants.FB_APP_ID);
AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(mFacebook);
Bundle bundle = new Bundle();
bundle.putString("fields", "birthday");
mFacebook.request("me/friends", bundle);
} catch(Exception e){
Log.e(Constants.LOGTAG, " " + CLASSTAG + " Exception = "+e.getMessage());
}
When I execute my activity, I'm not seeing anything, but in LogCat there is a debug message like:
06-04 17:43:13.863: DEBUG/Facebook-Util(409): GET URL: https://graph.facebook.com/me/friends?format=json&fields=birthday
And when I tried to access this url directly from the browser, I'm getting the following error response:
{
error: {
type: "OAuthException"
message: "An active access token must be used to query information about the current user."
}
}

You are about half way there. You've sent the request, but you haven't defined anything to receive the response with your results. You can extend BaseRequestListener class and implement its onComplete method to do that. Something like this:
public class FriendListRequestListener extends BaseRequestListener {
public void onComplete(final String response) {
_error = null;
try {
JSONObject json = Util.parseJson(response);
final JSONArray friends = json.getJSONArray("data");
FacebookActivity.this.runOnUiThread(new Runnable() {
public void run() {
// Do stuff here with your friends array,
// which is an array of JSONObjects.
}
});
} catch (JSONException e) {
_error = "JSON Error in response";
} catch (FacebookError e) {
_error = "Facebook Error: " + e.getMessage();
}
if (_error != null)
{
FacebookActivity.this.runOnUiThread(new Runnable() {
public void run() {
Toast.makeText(getApplicationContext(), "Error occurred: " +
_error, Toast.LENGTH_LONG).show();
}
});
}
}
}
Then in your request you can specify the request listener to use for receiving the response from the request, like this:
mFacebook.request("me/friends", bundle, new FriendListRequestListener());

Using FQL Query
String fqlQuery = "SELECT uid, name, pic_square FROM user WHERE uid IN " +
"(SELECT uid2 FROM friend WHERE uid1 = me() LIMIT 25)";
Bundle params = new Bundle();
params.putString("q", fqlQuery);
Session session = Session.getActiveSession();
Request request = new Request(session,"/fql", params,HttpMethod.GET, new Request.Callback(){
public void onCompleted(Response response) {
Log.i(TAG, "Result: " + response.toString());
try{
GraphObject graphObject = response.getGraphObject();
JSONObject jsonObject = graphObject.getInnerJSONObject();
Log.d("data", jsonObject.toString(0));
JSONArray array = jsonObject.getJSONArray("data");
for(int i=0;i<array.length();i++)
{
JSONObject friend = array.getJSONObject(i);
Log.d("uid",friend.getString("uid"));
Log.d("name", friend.getString("name"));
Log.d("pic_square",friend.getString("pic_square"));
}
}catch(JSONException e){
e.printStackTrace();
}
}
});
Request.executeBatchAsync(request);

I was dealing with that and I found the answer.
The problem is that you want to access to your data without previous registration with your facebook token.
First, you must to define your Facebook variable:
Facebook mFacebook = new Facebook(getString(R.string.fb_id));
Later, define your AsyncFacebookRunner:
final AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(mFacebook);
Ok, now you must to authorize your request, with autorize method. Note that you must implement callback methods on DialogListener(), put attention on onComplete() method. On that method you must to run the friend fetch request. Now your request will pass because now you are authenticated.
Now the code:
mFacebook.authorize(this, fb_perms, new DialogListener(){
/**
* Triggered on a successful Facebook registration.
*/
public void onComplete(Bundle values) {
mAsyncRunner.request("me/friends", new FriendListRequestListener());
}
/**
* Triggered on a FacebookError.
*/
public void onFacebookError(FacebookError e) {
}
/**
* Triggered on a DialogError.
*/
public void onError(DialogError e) {
}
/**
* Triggered when the User cancels the Facebook Login.
*/
public void onCancel() {
}
});
You can use the FriendListRequestListener class that was post by #Kon
I hope this helps.
Cheers!

Hi Please check below link
Facebook API for Android: how to get extended info regarding user`s friends?
Post on user's friends facebook wall through android application

I faced the same problem yesterday.
I wondering if you have overriden the onActivityResult() function?
private Facebook mFacebook=null;
...
...
...
#Override
protected void onActivityResult(int requestCode,
int resultCode,
Intent data) {
mFacebook.authorizeCallback(requestCode, resultCode, data);
}

Check this answer in order to know how to get Facebook friend list and who of these friends have installed your app using new Facebook SDK 3.0 for Android.

I'm doing something like this is working good....
jsonObj = Util.parseJson(facebook.request("me/friends"));
JSONArray jArray = jsonObj.getJSONArray("data");
for(int i=0;i<jArray.length();i++){
JSONObject json_data = jArray.getJSONObject(i);
Log.v("THIS IS DATA", i+" : "+jArray.getJSONObject(i));
}
Hope it is helpful...

If somebody is reading this in late 2015, the answer and code is quite simple. Take a look at official documentation here (in the code window click on Android SDK).
Keep in mind that you need to have user_friends permission.
Bro tip for android-rx users - get your friends synchronously, then process message and return Observable:
public Observable<List<Friend>> execute() {
return Observable.defer(new Func0<Observable<List<Friend>>>() {
#Override
public Observable<List<Friend>> call() {
AccessToken a = AccessToken.getCurrentAccessToken();
if (Utils.isValid(a)) {
try {
GraphResponse res = new GraphRequest(AccessToken.getCurrentAccessToken(), "me/friends").executeAndWait();
// process result
return Observable.just(your friend list);
} catch (Exception e) {
// notify user or load again
}
}
// invalid access token -> notify user
}
}).subscribeOn(Schedulers.io()).observeOn(AndroidSchedulers.mainThread());
}

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.
