I am trying to upload a picture to facebook using the sdk for android. When i run the code my app crashes. Can someone help me. I am not too sure how to use the sdk. Is there another way to upload pictures?
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.fragment_main);
bm = BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher);
// start Facebook Login
Session.openActiveSession(this, true, new Session.StatusCallback() {
// callback when session changes state
#Override
public void call(Session session, SessionState state, Exception exception) {
if (session.isOpened()) {
// make request to the /me API
Request.newUploadPhotoRequest(session, bm, new Request.Callback() {
#Override
public void onCompleted(Response response)
{
// TODO Auto-generated method stub
if (isFinishing()) {
return;
}
if (response.getError() != null) { // [IF Failed Posting]
Log.d("", "photo upload problem. Error="+response.getError() );
} // [ENDIF Failed Posting]
Object graphResponse = response.getGraphObject().getProperty("id");
if (graphResponse == null || !(graphResponse instanceof String) ||
TextUtils.isEmpty((String) graphResponse)) { // [IF Failed upload/no results]
Log.d("", "failed photo upload/no response");
} else { // [ELSEIF successful upload]
fbPhotoAddress = "https://www.facebook.com/photo.php?fbid=" +graphResponse;
}
}
} ).executeAsync();
}
}
});
}

When updating current user unique fields, not getting proper exception message from parse.
If i update username with existing username and send update request (save) using parse it is showing correctly.If now i reset the username back and give the existing email and update , it is returning username exists exception message instead of returning email exists message.
public void updateUserData(UserModel userModel) throws ParseException {
ParseUser user = ParseUser.getCurrentUser();
if (user != null && userModel != null){
if(userModel.getFirstName() != null) {
user.put(Constants.FIRST_NAME, userModel.getFirstName());
}
if(userModel.getLastName() != null) {
user.put(Constants.LAST_NAME, userModel.getLastName());
}
if(userModel.getUsername() != null) {
user.setUsername(userModel.getUsername());
}
if(userModel.getEmail() != null) {
user.setEmail(userModel.getEmail());
}
if (userModel.getPassword() != null) {
user.setPassword(userModel.getPassword());
}
if (userModel.getAvatar() != null) {
ParseFile file = new ParseFile(System.currentTimeMillis() + ".jpg", userModel.getAvatar());
file.save();
user.put("imageFile", file);
}
user.save();
}
}
Thanks in advance,
Please post if any have faced such issues.
change this code.
if (userModel.getAvatar() != null) {
final ParseFile file = new ParseFile(System.currentTimeMillis() + ".jpg", userModel.getAvatar());
file.saveInBackground(new SaveCallback() {
#Override
public void done(ParseException e) {
// TODO Auto-generated method stub
if (e == null) {
// success
user.put("imageFile", file);
// exit from one thered
UpdateDatabase(user);
} else {
// fail
e.getMessage();
}
}
});
}
then this code copy & paste.
protected void UpdateDatabase(ParseUser user) {
// TODO Auto-generated method stub
// before update parse table then set user permisson like read & write
user.saveInBackground(new SaveCallback() {
#Override
public void done(ParseException e) {
// TODO Auto-generated method stub
if (e == null) {
// success
} else {
// fail
e.getMessage();
}
}
});

I'm using FB SDK version 4.5.1 with eclipse to login to Facebook. Sometimes it login successfully, but some other times it gives me this error message " CONNECTION FAILURE". Is this a problem with my Internet connection or code?
Here is my code:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
FacebookSdk.sdkInitialize(getApplicationContext());
Log.d(TAG,"Fb initialzed");
callbackManager = CallbackManager.Factory.create();
//LoginButton loginButton= (LoginButton)findViewById(R.id.fb_login_button);
LoginManager.getInstance().registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
#Override
public void onSuccess(LoginResult result) {
// TODO Auto-generated method stub
Log.d(TAG,"Login success");
Intent I = new Intent(getApplicationContext(), Games.class);
startActivity(I);
}
private void showAlert() {
new AlertDialog.Builder(GameSurvey.this)
.setTitle(R.string.cancelled)
.setMessage(R.string.permission_not_granted)
.setPositiveButton(R.string.ok, null)
.show();
}
#Override
public void onCancel() {
// TODO Auto-generated method stub
Log.d(TAG,"Login cancelled");
}
#Override
public void onError(FacebookException error) {
// TODO Auto-generated method stub
if(error instanceof FacebookAuthorizationException)
Log.d(TAG,error.toString());
showAlert();
}
});
Log.d(TAG, "here");
setContentView(R.layout.activity_game_survey);
profileTracker = new ProfileTracker() {
#Override
protected void onCurrentProfileChanged(Profile oldProfile, Profile currentProfile) {
updateUI();
// It's possible that we were waiting for Profile to be populated in order to
// post a status update.
}
};
profilePictureView = (ProfilePictureView) findViewById(R.id.profilePicture);
}
If you get the error in the error handler callback, then you need to react to it (maybe show a notice to the user and request to try again).
A CONNECTION FAILURE error is self-explanatory. If you can find a specific pattern and you are able to repro this consistently on different networks and clients as well (e.g. web), then this might be a bug. Otherwise, this is unlikely to be a bug.
On my main activity, I have the following code:
FacebookSdk.sdkInitialize(getApplicationContext());
I also added a button to create a post on my Facebook timeline:
Button b1 = (Button) findViewById(R.id.button1);
b1.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
ShareLinkContent content = new ShareLinkContent.Builder()
.setContentUrl(Uri.parse("https://developers.facebook.com"))
.build();
ShareApi.share(content, new FacebookCallback<Sharer.Result>() {
#Override
public void onSuccess(Result arg0) {
// TODO Auto-generated method stub
}
#Override
public void onError(FacebookException arg0) {
// TODO Auto-generated method stub
}
#Override
public void onCancel() {
// TODO Auto-generated method stub
}
});
}
When I run my app on my smartphone, and click the button, I always get the following message (onError callback):
Insufficient permissions for sharing content via Api.
I have configured com.facebook.app.FacebookContentProvider, com.facebook.sdk.ApplicationId, com.facebook.FacebookActivity in Manifest file. And also have registered my app on facebook.
What is missing, please? Should I add a facebook Login button on my app?
I have discovered that this error occurs when AccessToken.getCurrentAccessToken() returns null. So I must authenticate to Facebook explicitly before using the ShareAPI.
I saw it in Facebook's source code available at http://android-education-project.googlecode.com/svn/trunk/facebook_4_0_0/src/com/facebook/share/ShareApi.java:

return;
}

try {
ShareContentValidation.validateForApiShare(shareContent);
} catch (FacebookException ex) {
ShareInternalUtility.invokeCallbackWithException(callback, ex);
return;

I want to share the text/image programatically from my app on facebook.How should I proceed for that.After lots of googling I found lots of sample apps but as the latest FB SDK is deprecated those APIs it is hard to find the way using new SDK.Please help me out for this issue.

This is what i get for fb API 3.5 doc & which I have tried but it is crashing the app by saying session is null.
Here your session is null because you have not started it yet.
You have to start your session after login.
You can achieve this by using
Session.openActiveSession(this, true, new Session.StatusCallback() {
// callback when session changes state
});
For more information try going through the tutorials from http://developers.facebook.com/docs/android/scrumptious/authenticate/. These are really helpful.
Here is how I implemented --
This class is used to do initial stuffs to facebook
LoginFacebookClass
/**

* Firstly import FacebookSDK lib project and add in your project as lib project.
* then
* create an instance of this class

* Please do whatever you want in the interface callback methods
* implemented by this class
*
*
* Note: Please write a line exactly in your activity's on activity result as
* -- Session.getActiveSession().onActivityResult(this, requestCode, resultCode, data);
* here, 'Session' is Class of Facebook.
* 'this' is reference of your activity

I implemented Facebook SDK in my Android application. I am using the login function of the SDK. What i am trying to do is the following :
When MainActivity starts, check if there is an active session
If there isn't, give the user the chance to login into facebook
If there is, user has to be redirected to an other Activity (let's call this : HomeActivity).
When my application starts, it starts the MainActivity. My onCreate() method looks like this :
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
this.app = (ApplicationClass)getApplicationContext();
app.setUiHelper(new UiLifecycleHelper(this, callback));
uiHelper = app.getUiHelper();
uiHelper.onCreate(savedInstanceState);
if(this.app.getLoggedIn()) {
setContentView(R.layout.login);
startLoggingIn(); // <-- Makes login button invisible and starts spinner
login();
} else {
setContentView(R.layout.login);
}
}
ApplicationClass is a class where i set all kind of information that can be used throughout the application lifecycle. It doesn't really matter but i thought i include it in the example.
So when MainActivity starts, it should call login() method, which looks like this :
public void login() {
logging_in = true;
Log.i(TAG, "Loggin in");
synchronized (this) {
// start Facebook Login
Session.openActiveSession(this, true, new Session.StatusCallback() {
// callback when session changes state
#Override
public void call(Session session, SessionState state, Exception exception) {
if (Session.getActiveSession().isOpened()) {
// make request to the /me API
Request.executeMeRequestAsync(session, new Request.GraphUserCallback() {
// callback after Graph API response with user object
#Override
public void onCompleted(GraphUser user, Response response) {
if (user != null) { // User is logged in
app.setUser(user);
app.setLoggedIn(true);
// Redirect user to the HomeActivity
Intent intent = new Intent(getBaseContext(), HomeActivity.class);
startActivity(intent);
}
}
});
}
}
});
logging_in = false;
}
}
And finally, my callback for Facebook session looks like this :
private void onSessionStateChange(Session session, SessionState state, Exception exception) {
if (state.isOpened()) {
synchronized (this) {
if( ! logging_in ) {
login();
}
}
} else if (state.isClosed()) {
setContentView(R.layout.login);
}
}
It does it all well, except the login() method gets called about many times. The output in my log is :
Why does it get called so many times? It obviously make sure the HomeActivity intent is started multiple times. I can't figure out why.
Solution
Changed my Session.StateCallback a little bit. It now looks like this :
private void onSessionStateChange(Session session, SessionState state, Exception exception) {
if (state.isOpened()) {
if(state == SessionState.OPENED_TOKEN_UPDATED) {
Log.i(TAG, "OPENED_TOKEN_UPDATED");
login();
} else if (state == SessionState.OPENED) {
if(app.getUser() != null) {
// Redirect user to the HomeActivity
Intent intent = new Intent(getBaseContext(), HomeActivity.class);
startActivity(intent);
} else {
login();
}
}
} else if (state.isClosed()) {
if(state == SessionState.CLOSED_LOGIN_FAILED) {
Log.i(TAG, "CLOSED_LOGIN_FAILED");
setContentView(R.layout.login);
} else if(state == SessionState.CLOSED) {
Log.i(TAG, "CLOSED");
//setContentView(R.layout.login);
}
}
}
Its most likely because you're calling login from onSessionState changed.
When you login what do think is going to happen to the session, it's going to change right.
And when it changes it calls onSessionState change and you call login.
I would expect that to loop infinitely but it seems Facebook have done some handling for this.
I also faced the same problem .. I just changed my activity result code . And it worked ..
