Dismiss facebook login dialog android

I've integrated facebook sdk v-4 with my android app. Here I've worked facebook login in 2 activities.
1) In one activity fb login is done via LoginButton. Where after successful login the fb login dialog is dismissed by facebook sdk automatically.
code:
fbLoginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
ProfileTracker profileTracker;
#Override
public void onSuccess(LoginResult loginResult) {
Logger.d("FBLOGIN", "login successful. User ID: "
+ loginResult.getAccessToken().getUserId()
+ "\n" +
"Auth Token: "
+ loginResult.getAccessToken().getToken());
com.facebook.Profile fbProfile = com.facebook.Profile.getCurrentProfile();
if (fbProfile == null) {
profileTracker = new ProfileTracker() {
#Override
protected void onCurrentProfileChanged(com.facebook.Profile oldProfile, com.facebook.Profile currentProfile) {
profileTracker.stopTracking();
doTaskWithFbProfile(currentProfile);
}
};
profileTracker.startTracking();
} else {
doTaskWithFbProfile(fbProfile);
}
}
#Override
public void onCancel() {
Logger.d(TAG, "fb Login attempt canceled.");
}
#Override
public void onError(FacebookException e) {
Logger.e(TAG, "fb Login attempt failed." + e);
Toast.makeText(LoginActivity.this,R.string.str_please_check_your_internet_connection,Toast.LENGTH_LONG).show();
}
});
private void doTaskWithFbProfile(com.facebook.Profile fbProfile) {
Logger.d("FBLOGIN", "id - " + fbProfile.getId());
Logger.d("FBLOGIN", "name - " + fbProfile.getName());
Logger.d("FBLOGIN", "pic - " + fbProfile.getProfilePictureUri(150, 150));
com.android.circlecare.models.common.Profile profile = new com.android.circlecare.models.common.Profile();
profile.setFBID(fbProfile.getId());
profile.setName(fbProfile.getName());
profile.setProfilePhoto(fbProfile.getProfilePictureUri(150, 150).toString());
Intent intent = new Intent(this, LoginWithFacebookActivity.class);
intent.putExtra(LoginWithFacebookActivity.EXTRA_PROFILE, profile);
startActivity(intent);
finish();
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
callbackManager.onActivityResult(requestCode, resultCode, data);
}
2)On the other hand I used LoginManager to log in to fb. Where after successful login the login dialog does not get dismissed, instead it stays in front and again after login the dialog doesn't go.
code:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
FacebookSdk.sdkInitialize(this.getApplicationContext());
mFacebookCallback = new FacebookCallback<LoginResult>() {
ProfileTracker profileTracker;
#Override
public void onSuccess(LoginResult loginResult) {
Profile fbProfile = Profile.getCurrentProfile();
if (fbProfile == null) {
profileTracker = new ProfileTracker() {
#Override
protected void onCurrentProfileChanged(Profile oldProfile, Profile currentProfile) {
profileTracker.stopTracking();
getAllFriends();
}
};
profileTracker.startTracking();
} else {
getAllFriends();
}
}
#Override
public void onCancel() {
Logger.d(TAG, "fb Login attempt canceled.");
}
#Override
public void onError(FacebookException error) {
Logger.d(TAG, "Error : " + error.getMessage());
finish();
}
};
callbackManager = CallbackManager.Factory.create();
if (hasAccess)
getAllFriends();
else
loginWorks();
}
private void loginWorks() {
loginManager = LoginManager.getInstance();
loginManager.registerCallback(callbackManager, mFacebookCallback);
ArrayList<String> publishPermission = new ArrayList<>();
publishPermission.add("publish_pages");
publishPermission.add("publish_actions");
loginManager.logInWithPublishPermissions(this, publishPermission);
ArrayList<String> readPermission = new ArrayList<>();
readPermission.add("user_friends");
readPermission.add("public_profile");
readPermission.add("user_about_me");
loginManager.logInWithReadPermissions(this, readPermission);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
callbackManager.onActivityResult(requestCode, resultCode, data);
}
I've used almost same codes in both the cases, but I wonder why login dialog isn't get dismissed when working with LoginManager.
Can any one point out the problem or is there any api to dismiss fb login dialog(web view).

In your loginWorks() method, you're literally calling login twice, which is probably actually showing 2 different login screens, and why it looks like the dialog is not dismissing after you finish one of them. Try removing the loginWithPublishPermissions call, and put it in the callback from the read permissions call if you really need it.

Android Facebook Log In with AWS Cognito

I'm having trouble authenticating users with Facebook and creating a single new identity with AWS Cognito. Then if that user deletes the app and re-downloads it I want Cognito to return the same identity.
Facebook login works but credentialsProvider.setLogins(logins); creates 4 NEW unauthenticated identities every time.
final CognitoCachingCredentialsProvider credentialsProvider = new CognitoCachingCredentialsProvider(getApplicationContext(), "xxxxxxxx", Regions.US_EAST_1);
loginButton = (LoginButton) findViewById(R.id.login_button);
loginButton.setReadPermissions(Arrays.asList("email", "user_friends"));
callbackManager = CallbackManager.Factory.create();
accessTokenTracker = new AccessTokenTracker() {
#Override
protected void onCurrentAccessTokenChanged(
AccessToken oldAccessToken,
AccessToken currentAccessToken) {
updateWithToken(currentAccessToken);
}
};
loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
#Override
public void onSuccess(LoginResult loginResult) {
Map<String, String> logins = new HashMap<String, String>();
logins.put("graph.facebook.com", AccessToken.getCurrentAccessToken().getToken());
credentialsProvider.setLogins(logins);
Log.d("LogTag", "my ID is " + logins);
}
#Override
public void onCancel() {
Toast.makeText(getBaseContext(), "Login Cancelled", Toast.LENGTH_SHORT).show();
Log.v("LoginActivity", "cancel");
}
#Override
public void onError(FacebookException exception) {
Toast.makeText(getBaseContext(), "Problem connecting to Facebook", Toast.LENGTH_SHORT).show();
Log.v("LoginActivity", exception.getCause().toString());
}
});
}
private void updateWithToken(AccessToken token) {
if (token != null) {
Intent intent = new Intent(LogIn.this, NavDrawer.class);
LogIn.this.startActivity(intent);
}
;
}
#Override
public void onDestroy() {
super.onDestroy();
accessTokenTracker.stopTracking();
}
#Override
protected void onResumeFragments() {
super.onResumeFragments();
updateWithToken(AccessToken.getCurrentAccessToken());
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
callbackManager.onActivityResult(requestCode, resultCode, data);
Intent intent = new Intent(LogIn.this, Buffer.class);
LogIn.this.startActivity(intent);
}
}
Any help would be amazing, thanks you!

I can see you are starting a new activity every time your access token from Facebook is updated. That mean you are creating different instances of CognitoCachingCredentialsProvider every time, which is not right.
Ideally you should have CognitoCachingCredentialsProvider as a singleton in your application and use is in all you activities and app logic. You can use the Cognito sample application as an example to model the flow.

Android Facebook - get null profile

First time with Facebook SDK. I can't get users profile. Its always null. What's wrong?
btnFbWidget = (LoginButton) findViewById(R.id.btnFbWidget);
btnFbWidget.setReadPermissions("public_profile");
// Callback registration
btnFbWidget.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
#Override
public void onSuccess(LoginResult loginResult) {
Profile profile = Profile.getCurrentProfile();
if (profile != null)
Toast.makeText(getApplicationContext(), "LogIN as " + profile.getName(), Toast.LENGTH_SHORT).show();
else
Toast.makeText(getApplicationContext(), "nulll", Toast.LENGTH_SHORT).show();
}
/*...*/
});

use this method also,.....
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
callbackManager.onActivityResult(requestCode, resultCode, data);
}

Try with this method.
Initialize facebook SDK firstly.
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//init facebook sdk and
FacebookSdk.sdkInitialize(getApplicationContext());
setContentView(R.layout.activity_main);
//instantiate callbacks manager
mCallbackManager = CallbackManager.Factory.create();
btnFbWidget=(LoginButton)findViewById(R.id.login_button);
btnFbWidget.registerCallback(mCallbackManager, this);
btnFbWidget.setReadPermissions(Arrays.asList("user_status","email"));
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
//manage login result
mCallbackManager.onActivityResult(requestCode, resultCode, data);
}
public void onSuccess(LoginResult loginResults) {
Toast.makeText(getApplicationContext(), "Success ",
Toast.LENGTH_LONG).show();
}
public void onCancel() {
}
public void onError(FacebookException e) {
}
And then to get the User Profile use this method.
private static String uid,email;
public void getUserProfile() {
GraphRequest request = GraphRequest.newMeRequest(
AccessToken.getCurrentAccessToken(),
new GraphRequest.GraphJSONObjectCallback() {
#Override
public void onCompleted(
JSONObject object,
GraphResponse response) {
// Application code
Log.v("LoginActivity", response.toString());
try {
//and fill them here like so.
uid = object.getString("id");
email = object.getString("email")
} catch (JSONException e) {
e.printStackTrace();
}
getGroups();
}
});
// If you want to pass data to other activity.
Bundle parameters = new Bundle();
parameters.putString("userdata", "email");
request.setParameters(parameters);
request.executeAsync();
}
And do call this method getUserProfile() in your on create.
EDIT 1 :
Change in read permissions.
btnFbWidget.setReadPermissions(Arrays.asList("public_profile", "email", "user_birthday", "user_friends"));
And accordingly you can get further information like.
String email = object.getString("email");
String birthday = object.getString("birthday");

Android facebook isn't able to send/post to a friend using SDK 4.1

Here,I'm getting logged into the app using facebook account using 4.1. But now I want to send message to a friend or post something to a friend's wall but I'm not getting a proper answer for doing it.
onCreate(){
FacebookSdk.sdkInitialize(getApplicationContext());
callbackManager = CallbackManager.Factory.create();
.
.
loginButton = (LoginButton) findViewById(R.id.login);
loginButton.setReadPermissions(Arrays.asList("public_profile, email, user_birthday, user_friends","publish_actions"));
}
loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
#Override
public void onSuccess(LoginResult loginResult) {
}
#Override
public void onCancel() {
Log.d(TAG, "Login Canceled");
}
#Override
public void onError(FacebookException error) {
Log.d(TAG, "Login Error");
}
});
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
// manage login results
callbackManager.onActivityResult(requestCode, resultCode, data);
}

Facebook Login Not Returning User access_token

This is my first post, so please let me know if I'm not abiding by the community rules.
Now to the problem! I've been trying to setup the Facebook login process for an app and I've gotten as far as adding a GUI element (the built-in Facebook login button), and having the button go ahead and ask for a user/pass, granting the app access to the user's account. The problem I'm facing is that when using the following code to get a callback value from the app I receive nothing (no value being printed). Right now I'm printing to LogCat arbitrary values, however as soon as printing works, I look to access the user access_token and other information (which didn't initially work). Any help appreciated!
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_connect_accounts);
Log.i("fromMe", "test1");
FacebookSdk.sdkInitialize(this.getApplicationContext());
callbackManager = CallbackManager.Factory.create();
LoginButton loginButton = (LoginButton)findViewById(R.id.login_button);
loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>(){
public void onSuccess(LoginResult loginResult) {
Log.i("fromMe", "1");
}
public void onCancel() {
Log.i("fromMe", "2");
}
public void onError(FacebookException exception) {
Log.i("fromMe", "3");
}
});
}

if Log.i("fromMe", "1");work so you can call :
AccessToken accessToken = loginResult.getAccessToken();
in your onSuccess().
And in onActivityResult(int requestCode, int resultCode, Intent data)
add :
super.onActivityResult(requestCode, resultCode, data);
callbackManager.onActivityResult(requestCode, resultCode, data);

I never used the built-in facebook button ,instead i used the normal button with a click a listener. and i call this method in the onClick().
myButton.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v){
//Starting facebook signIN
startFbSignIn();
}
});
startFbSignIn();
private void startFbSignIn() {
List<String> permissions = new ArrayList<>();
permissions.add("email");
Session.openActiveSession(this, true, permissions, new Session.StatusCallback() {
#Override
public void call(final Session session, SessionState sessionState, Exception e) {
Log.d("X", "Call Called");
if (session.isOpened()) {
Log.d("X", "SessionOpened" + session.getAccessToken());
//Showing some loading
Request.newMeRequest(session, new Request.GraphUserCallback() {
#Override
public void onCompleted(GraphUser graphUser, Response response) {
//FACEBOOOK SIGNIN SUCCESS
Log.i("X", "Facebook Login Success");
//Log
Log.d("X", "GRAPH USER:" + graphUser.toString());
String name = graphUser.getName();
//.....
}
}).executeAsync();
} else {
Log.d("X", "SessioNOTopened");
}
}
});
}
The above method successfully working for me and your onActivityResult() must look something like this
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
//Facebook Session Manager
Session.getActiveSession().onActivityResult(this, requestCode, resultCode, data);
}

Probably cause of a bug in the facebook SDK you cannot directly get the accessToken. We need to create an accessToken tracker and then get the accessToken
private AccessTokenTracker accessTokenTracker;
accessTokenTracker = new AccessTokenTracker() {
#Override
protected void onCurrentAccessTokenChanged(AccessToken oldAccessToken, AccessToken newAccessToken) {
try {
if (newAccessToken.getToken() != null) {
facebookAccessToken = newAccessToken.getToken();
//this is your accessToken here
}
else if (oldAccessToken.getToken() != null) {
facebookAccessToken = oldAccessToken.getToken();
//this is your accessToken here
}else {
Toast.makeText(getBaseContext(), "Facebook Login Failed", Toast.LENGTH_LONG).show();
}
if(oldAccessToken.getToken()!=null)
Log.e("old", oldAccessToken.getToken());
}catch (Exception e){
e.printStackTrace();
}
}
};
once this is successfully done, overide the onStop method of the activity and make sure you stoptracking the accessToken there.
accessTokenTracker.stopTracking();
