After upgrading to latest XamarinFacebookAndroid using nuget, I am receiving the following error while building.

My guess is the inclusion of support library custom tab as dependency.

/Library/Frameworks/Mono.framework/External/xbuild/Xamarin/Android/Xamarin.Android.Common.targets: error : Tool exited with code: 2. Output:

Hi,
I tried both samples that are included with the component and both only open the web view :(

Could someone please update the sample so they actually do open the native UI when logging in?
Or maybe there is a bug?!?

Just in case - all works when logging through the web view for both samples. Just the native UI will not show :(

Also - I'm running them from VS and all is setup on the Mac so I can deploy on iPhone device where Facebook app is installed.

Regards.

The only change in my app submission was to update the Xamarin.iOS Facebook nuget package from version 4.27.1 to 4.33.0.

The submission with 4.27.1 passed and the version with 4.33.0 was rejected with the following error:

Missing Info.plist key - This app attempts to access privacy-sensitive data without a usage description. The app's Info.plist must contain an NSBluetoothPeripheralUsageDescription key with a string value explaining to the user how the app uses this data.

I really don't want to ask for Bluetooth permissions when the only Facebook feature I'm using is login. There is no plausible explanation for why my game would need this permission. It doesn't even have advertising to use as an excuse.

Dear,
we have a big issue with FB Audience component.

We have integrating Facebook Audience Network on iOS with a placement but on different devices and FB accounts API answer is always this

[FBAudienceNetworkLog/FBAdProvider:137 ] Ad request error: Error Domain=com.facebook.ads.sdk Code=1001 "No fill" UserInfo={FBAdErrorDetailKey={ msg = "No fill. We are not able to serve ads to this person. Please refer to https://developers.facebook.com/docs/audience-network/faq#a12. If you are integrating Audience Network for the first time, you can use test ads https://developers.facebook.com/docs/audience-network/testing."; }, NSLocalizedDescription=No fill}

We have referred also docs a12 but there are "No limits on iOS ads" and all accounts are logged to Facebook.

We have read carefully documentation and we have check condition of "No fill" on iOS and Android.

We would like to use Facebook Native Ads in our job listing each 5 job advert we want show 1 Facebook Native Ads.

What is strange is this case (on same device):

Installing app in DEBUG MODE Facebook Native Ads are shown correctly
Installing app in RELEASE MODE USING TESTFLIGHT Facebook Native Ads respond "No Fill"
Same TestFlight app installed via APPSTORE Facebook Native Ads LOCK others HTTP requests. We have check it via Charles (http://www.charlesproxy.com/) and API call does not start because is in loading Facebook call. This happens on all devices that download app via APPSTORE.

Our app is developed via Xamarin Component https://components.xamarin.com/view/fbaudiencenetworkios

What seems really strange is same code on same device and same FB user (mine Luigi Saggese) on different release type have different behaviour.
Debug Mode: OK
Release Mode using TestFlight: "No Fill" without locking other API calls
App Store: No response locking other API calls

On TestFlight mode we have found this answer on StackOverflow that seems realistic (http://stackoverflow.com/questions/29779758/facebook-native-ads-on-ios) "Test Flight rotates through a pool of IDFA's and hides the users true IDFA, making it difficult to identify a Facebook user – and that is required for delivering an ad."

Please help us to solve this issue, we have also written to Facebook support and they say as that Xamarin is maintaining component.
https://developers.facebook.com/bugs/1050931391633784

In iOS 12, when you receive an SMS message with an OTP or a verification code, the OS suggests the OTP in the keyboard’s quick type field. This can come in really handy because while it’s obviously possible to view the message and remember the OTP, it’s far easier to just tap on the quick type field and have it automatically entered in.
But AccountKit not support this features. I can't set textContentType of textfield in AccountKit UI. I need set
otpTextField.textContentType = .oneTimeCode to get code from sms to keyboard.

Has AccountKit support it ? Add new feature to new version of AFK ?

Hi people,
I implemented Facebook.ShareKit.ISharingDelegate interface in order to get Callback from the user sharing, In other words, if the user opens the Sharing Webview the app should know the result(DidComplete, DidFail or DidCancel). That's something like IFacebookCallback interface from Xamarin.Facebook.Android. Below, it's my code. MyShareDelegate doesn't execute any of its methods.

Thanks.

Facebook (for iOS at least) is now on 4.20.2: https://github.com/facebook/facebook-ios-sdk/releases

Is there any plans to update these components?

I took a stab at doing it myself by modifying GIT_REPO_TAG in the Makefile, but I get a build error:

cp: ../Bolts-IOS/build/ios/Bolts.framework: No such file or directory

I think this is coming from build_distribution_xamarin.sh.

This is an issue for us, because there is a bug in the iOS Facebook SDK 4.18 that breaks login. Right now we are having to run the 4.16.1 version of the Xamarin.Facebook.iOS NuGet package because of this.

Hello, I created a new Xamarin project and I'm using Xamarin.Facebook.iOS 4.38.0.

At first my application is requesting read permissions to make the registration/login.

public static List<string> FacebookReadPermissions = new List<string> {
            "public_profile",
            "email"
};

.  .  .

loginManager.LogInWithReadPermissions(FacebookReadPermissions.ToArray(), this, (results, errors) => {
    .
    .
    .
}

Then I try to publish so I ask for ["publish_actions"] permissions, but the token is always null and it shows the following message:

public static List<string> FacebookPublishPermissions = new List<string> {
            "publish_actions",
};

.  .  .

loginManager.LogInWithPublishPermissions(AppDelegate.FacebookPublishPermissions.ToArray(), this, (result, error) => 
{
    .
    .
    .
    if (result.Token == null)
    {
        // result is null
    }

    // Manage success
}

Any ideas?

Our iOS users are complaining of the following error while signing in

The operation couldn’t be completed. (com.facebook.sdk.login error 308.)

It appears to have been resolved in 4.38.1
facebook/facebook-ios-sdk#922 (comment)

I would greatly appreciate if you could upgrade the nuget packages.

Thanks 🙏

VS bug #751310

When I update to v4.35, I get a build error The binding library 'Facebook.LoginKit.dll' contains a user framework (Facebook.LoginKit.dll), but embedded user frameworks require iOS 8.0 (the deployment target is FBSDKLoginKit.framework). Please set the deployment target in the Info.plist file to at least 8.0.

So, that means that I can't use v4.35 and newer in my iOS project if I want to keep the deployment target on iOS 7? Why? Until now, I was using a runtime condition to check whether the iOS is 9.0+ and disable Facebook SDK otherwise. But this is now not possible.

Can this be fixed or is it now "iOS7 or v4.35"?

My app has multiple login options; of which FB Login is one of the options. Clicking "cancel" on the "confirm login" page on facebook login causes you to be taken to a troubleshooting page the next time you attempt.

Steps: Open the app that is not currently logged in but has been logged in using facebook in the past.

1 - Click on Login (Existing User)

2 - Click Login with Facebook

3 - You should be taken to a "confirm login" page where is tells you "you previously logged in to App with Facebook"

4 - Click cancel and it takes you to the Login screen

5 - Press "Login with Facebook" again

6 - If done consecutively you will be taken to the Facebook Help Center

Please let me know if this is an expected behaviour or this needs to be handled.

The error I am getting when clicking cancel is:
error_reason=user_denied
&error=access_denied
&error_description=Permissions+error.

More info:
We are using Xamarin.Facebook.iOS.4.27.1 nuget package.

We are logging in to account as per "LoginButtonCompletedEventArgs.Result".
If "LoginButtonCompletedEventArgs.Result.Token" is not null, that is taken forward for successful login and hence proceeded.

In the reported bug scenario, we are getting
"LoginButtonCompletedEventArgs.Result.IsCancelled" as TRUE when we click "Cancel" in login confirmation page as well as "Done" in Help Center page.

Could you kindly try replicating the issue using the above mentioned package?
Also please let me know if this issue, "authorize/?error=access_denied&error_code=200&error_description=Permissions+error&error_reason=user_denied" when triggered multiple times could make Facebook suggest the user to report the app for any suspected attack?

My app (Xamarin Forms) needs to use write permission for GraphRequest and wall-posting.

What I try to do:
Using Xamarin.Facebook.iOS (v 4.35)

    readonly LoginManager _loginManager = new LoginManager();
    readonly string[] _permissions = { @"public_profile", @"email", @"user_posts", @"user_photos"};
    LoginResult _loginResult;
    TaskCompletionSource<LoginResult> _completionSource;
    public Task<LoginResult> LoginWithPublish()
    {
        _completionSource = new TaskCompletionSource<LoginResult>();
        _loginManager.LogInWithPublishPermissions(_permissions, GetCurrentViewController(), LoginManagerLoginHandler);
        return _completionSource.Task;
    }

   void LoginManagerLoginHandler(LoginManagerLoginResult result, NSError error)
    {
        if (result.IsCancelled)
            _completionSource.TrySetResult(new LoginResult { LoginState = LoginState.Canceled });
        else if (error != null)
            _completionSource.TrySetResult(new LoginResult { LoginState = LoginState.Failed, ErrorString = error.LocalizedDescription });
        else
        {
            _loginResult = new LoginResult
            {
                Token = result.Token.TokenString,
                UserId = result.Token.UserId,
                ExpireAt = result.Token.ExpirationDate.ToDateTime()
            };

            var request = new GraphRequest(@"me", new NSDictionary(@"fields", @"email"));
            request.Start(GetEmailRequestHandler);
        }
    }

So, when i try to call LoginWithPublish, handler LoginManagerLoginHandler is never called.
Just nothing is happing.

If I calling LoginWithReadPermissions (and same Handler), i can get login, but when i try call GraphRequest "{user_id}/photos?url="url"" a got this error (and it is quite logical).

Error Domain=com.facebook.sdk.core Code=8 "(null)" UserInfo={com.facebook.sdk:FBSDKGraphRequestErrorCategoryKey=0, com.facebook.sdk:FBSDKGraphRequestErrorHTTPStatusCodeKey=403, com.facebook.sdk:FBSDKErrorDeveloperMessageKey=(#200) Requires extended permission: publish_actions, com.facebook.sdk:FBSDKGraphRequestErrorGraphErrorCode=200, com.facebook.sdk:FBSDKGraphRequestErrorParsedJSONResponseKey={
    body =     {
        error =         {
            code = 200;
            "fbtrace_id" = DBHvrFFmvfB;
            message = "(#200) Requires extended permission: publish_actions";
            type = OAuthException;
        };
    };
    code = 403;
}}

But I unable just to add publish_actions to list of my permissions, that's related to update of FB api.

How I can get write permissions or any another way to do wall-post on FB with Xamarin.Forms?

Hello, for past few days I've been trying to implement ads mediation in my Xamarin.Android app and the first service I wanted to use for this was Facebook. Unfortunately I've run into a multitude of different issues and in the end I've decided to ask here. My problem is:

It could be caused by broken(?) desugar of java 8 as mentioned here. It doesn't even work when I set min-sdk to 26... which is no go anyway.

The first NuGet version that causes this issue is: 4.22.0, earlier ones don't work though as I'm guessing that Facebook deprecated older APIs.
The error occurs only when the components are actually used in code with such class for example:

    [Preserve(AllMembers = true)]
    public class FacebookCustomEventBanner : Java.Lang.Object, ICustomEventBanner
    {
        private AdView _adBanner;

        public void OnDestroy()
        {
            _adBanner?.Destroy();
        }
        ...
        public void RequestBannerAd(Context context,
            ICustomEventBannerListener listener,
            string serverParameter,
            AdSize size,
            IMediationAdRequest mediationAdRequest,
            Bundle customEventExtras)
        {
            _adBanner = new AdView(context, "<>", Xamarin.Facebook.Ads.AdSize.BannerHeight50);
            _adBanner.SetAdListener(new FacebookCustomEventBannerForwarder(listener, _adBanner));
            _adBanner.LoadAd();
        }
    }

Am I missing something obvious here? Or is it just impossible to use it right now?

VS bug #732196

VS bug #724981

https://www.facebook.com/audiencenetwork/news-and-insights/required-changes-for-audience-network-publishers

The Facebook SDK is moving towards a more modular sdk. With that said, a redesign for the Xamarin.FacebookComponents might be in order for continued support of this binding library. This seems very similar to what happened with the now deprecated GooglePlayServices package.

I would like this issue to serve as an enhancement request for breaking out the FacebookComponent into more modular/manageable packages.

Currently the facebook sdk v4.26, at least on Android, is the last version before changing the architecture.

As noted in #19, this repo might not be Xamarin's highest priority at this time. However, I do want to get this issue going so that the community might start it.

Currently AudienceNetwork/AccountKit are not wrapped under this issue, they remain outside Facebook's core sdk grouping. However, it might make sense to break AudienceNetwork out of the Android Facebook solution once it starts adapting to the new facebook sdk architecture.

Thanks.

is it possible to support MonoAndroid v8.0 ?

I now using the 4.34 for Android, but seems doesn't working.

I added this to AndroidManifest.xml, but couldn't found fb_codeless_debug in event debug.
<meta-data android:name="com.facebook.sdk.CodelessDebugLogEnabled" android:value="true" />

Can't Connect?
Check this list then close and reopen your app and try again.
Your app has Facebook SDK v.4.34 or higher.
You're using the latest version of your app.
You're shaking your phone firmly enough.
If your WiFi is unreliable, connect to high-speed Internet.

The iOS 4.35 is working perfectly for fb_codeless_debug.

Thank you very much.

Hello.

I'd like to display interstitialAd using Audience Network.
However, I found a little problem with iOS.
With IInterstitialAdDelegate, the Delegate method (InterstitialAdWillClose () or InterstitialAdDidClose ()) should be called when the ad is closed, but sometimes the Delegate method is not called.
We prepared all methods that we can export, but even IntersitialDidFail () is not called.

Is this a bug?
There was no particular problem when using AdMob's mediation.
I want hints to solve if it is not a bug.

I am sorry if this is a Google translation, so it makes sense for me.

Thank you.

Facebook xamarin android version:- 4.26.0
Issue: Cannot login via Facebook when the facebook app is installed in the phone.
Actual behaviour:- Facebook button does not respond
Expected behaviour:- app should properly launch and return result from Facebook

In Kitkat device i noticed that if the Activity LaunchMode is SingleInstance it wont show the facebook page, If i change it back to SingleTop or SingleTask it works as expected.
How does the launch mode of the activity dependent on the facebook login?

Why Xamarin Facebook iOS binding don't binding [[FBSDKSettings accessTokenCache] fetchAccessToken]?

I'm writing to see if there are any plans to include the FBNotifications library to take advantage of in-app notifications. Thank you.

I upgraded my iOS project's Facebook component from Nuget (v4.33.0), and sent a new build to iTunes for review. The binary was immediately rejected.

The email from iTunes stated that:

Missing Info.plist key - This app attempts to access privacy-sensitive data without a usage description. The app's Info.plist must contain an NSBluetoothPeripheralUsageDescription key with a string value explaining to the user how the app uses this data.

I was totally puzzled because there is no single line of code related to Bluetooth usage in my code. After some trial and error, I downgraded Facebook component version and the new build got accepted.

I don't think that Facebook's official libraries use any Bluetooth functions. Is this a Xamarin-specific issue? Why are we supposed to add NSBluetoothPeripheralUsageDescription key just for Facebook-related activities?

The binding for Facebook.CoreKit.ApplicationDelegate.SharedInstance.OpenUrl has a NSDictionary<NSString, NSObject> options parameter, but the iOS binding for AppDelegate.OpenUrl provides a non-generic NSDictionary.

This means any use of OpenUrl has to cast the NSDictionary before it can call the URL, which is pretty user-unfriendly, especially as this is the only place that OpenUrl would be called from.

Would be nice to have an overload which takes the standard NSDictionary and converts it.

Facebook style resources dont load when running application.
App instantly crashes with the follow error
Java.Lang.NoClassDefFoundError: Failed resolution of: Lcom/facebook/R$style;

Sharing link using ShareLinkContent.Builder was working fine then, until few weeks ago.

Everything is still working just like the same , except the link I am sharing is getting this "Message could not be sent.Tap for details" at the messenger.

SDK Upgrade: iOS v4.37.0  

{AppName} currently uses Facebook SDK for iOS v4.27.1, which relies on the recently deprecated Version 2.7 of the Graph API.

As a result, there is a risk that your app will no longer function if you don't upgrade to Facebook SDK for iOS v4.37.0.As an admin of this app, please upgrade to the latest SDK as soon as possible to ensure your app's continued performance and to take advantage of new features.

 Any plans upgrading?

I installed the facebook account kit via nuget and getting below error while building the application.
version: 4.28.0

error: OnSpinnerEventsListener is not public in CountryCodeSpinner;
cannot be accessed from outside package
com.facebook.accountkit.ui.CountryCodeSpinner.OnSpinnerEventsListener
App8
..\obj\Debug\android\src\mono\com\facebook\accountkit\ui\CountryCodeSpinner_OnSpinnerEventsListenerImplementor.java

it says the OnSpinnerEventsListener is not public in CountryCodeSpinner. But how can i modify it? Or is there anything need to be added in the xamarin application to build it successfully.

VS bug #844214

Hi, when I use this:

PhoneLogin.AsIViewControllerProtocol()

The registrar found an invalid interface 'Facebook.AccountKit.IViewController': The interface must have a Protocol attribute specifying its wrapper type

In debug works fine

Hi,

any chance we get Facebook AudienceNetwork iOS SDK on nuget ?

I can see the SDK for Android, but not the one for iOS.

Thanks !

Hello is it possible to run this again and have the latest SDK from facebook ? if yes how can we do that ?

Step 4 of Migration Steps in the SDK 4.99 Upgrade Guide states:

NativeAd interface changes:
registerViewForInteraction(View) is replaced by registerViewForInteraction(View, MediaView, AdIconView) where AdIconView is optional.
registerViewForInteraction(View, List) is replaced by registerViewForInteraction(View, MediaView, AdIconView, List) where AdIconView is optional.

It appears that during the upgrade to 5.0.1 these methods were lost. The NativeBannerAd class also appears to be missing this method handler.

Please update the SDK to support Native Ads.
Thanks 🙂

VS bug #792686

Hi guys

after updating this component to last available 4.18.0.1 in Xamarin components portal we started to have an issue with AccessToken.CurrentAccessToken. It returns null after a successful login followed by an app restart.
Of course that we do have all things that fb tell us to do

public override bool FinishedLaunching
...

Profile.EnableUpdatesOnAccessTokenChange(true);
Settings.AppID = FacebookAppId;
Settings.DisplayName = DisplayName;

return ApplicationDelegate.SharedInstance.FinishedLaunching(app, options);

This seems to be related to permissions or so. Any guess?

cheers
Manuel

Facebook fixed some bugs in the new release and it'd be great to have related xamarin sdk version. Thanks.

VS bug #792688

Hi,

I'm unable to login into my App using Facebook API because this library's SDK is out of date. In the output console the following message appears: "Your Facebook SDK is out of date. We recommend upgrading to the latest Version 4.37.0, to ensure your app's performance is not affected and to take advantage of our newest features!".

Please, could you update this library to the latest SDK? Thank you in advance.

The crash "Xamarin.iOS: Received unhandled ObjectiveC exception: NSInvalidArgumentException *** setObjectForKey: object cannot be nil (key: logging_token)" is received when attempting to sign into Facebook on a device running iOS8. This crash will not occur if the same project setup is used on a just an Xcode project. The quickest way to repo the issue is to use the Facebook sample while using the latest Xamarin.Facebook.iOS package in the nuget store. Simply hitting the Continue with Facebook causes the issue.

My app has multiple login options; of which FB Login is one of the options. Clicking "cancel" on the "confirm login" page on facebook login causes you to be taken to a troubleshooting page the next time you attempt.

Steps: Open the app that is not currently logged in but has been logged in using facebook in the past.

1 - Click on Login (Existing User)

2 - Click Login with Facebook

3 - You should be taken to a "confirm login" page where is tells you "you previously logged in to App with Facebook"

4 - Click cancel and it takes you to the Login screen

5 - Press "Login with Facebook" again

6 - If done consecutively you will be taken to the Facebook Help Center

Please let me know if this is an expected behaviour or this needs to be handled.

The error I am getting when clicking cancel is:
error_reason=user_denied
&error=access_denied
&error_description=Permissions+error.

More info:
We are using Xamarin.Facebook.iOS.4.33.0 nuget package.

We are logging in to account as per "LoginButtonCompletedEventArgs.Result".
If "LoginButtonCompletedEventArgs.Result.Token" is not null, that is taken forward for successful login and hence proceeded.

In the reported bug scenario, we are getting
"LoginButtonCompletedEventArgs.Result.IsCancelled" as TRUE when we click "Cancel" in login confirmation page as well as "Done" in Help Center page.

Could you kindly try replicating the issue using the above mentioned package?
Also please let me know if this issue, "authorize/?error=access_denied&error_code=200&error_description=Permissions+error&error_reason=user_denied" when triggered multiple times could make Facebook suggest the user to report the app for any suspected attack?

NOTE:- I have tried all the changes mentioned in an issue closed recently. (#88)

Can you give an example how to use the method AppLinkData.FetchDeferredAppLinkData(...) in Xamarin.Facebook.Android v.4.26.0?

We got an email from facebook for API upgrade. It ask to upgrade to Facebook API v3.1 from current 2.7.

Currently we used Xamarin.facebook.android 4.34 and Xamarin.facebook.iOS 4.35
So when can we expect that upgraded FB API 3.1 in nugget package for Xamarin.android and Xamarinn.iOS?

Thanks.

Add iOS and Android binding libraries for Facebook's Account Kit

Every time I try to log in on iOS 7 and 8, the app crashes, right after clicking the Facebook button.
So iOS 7 and 8 is now not supported? Why, could this be fixed?
I am using version 4.27.1.

I find this quite odd, in order to make use of the builder in order to share a post with facebook, you're having to cast the result of a builder operation.

var builder = new ShareLinkContent.Builder()
    .SetQuote(postCaption)
    .SetContentUrl(Android.Net.Uri.Parse(postImageUrl)) as ShareLinkContent.Builder;

var shareContent = builder.Build();

This is nuts! Is this caused by a binding issue in the Android sdk?

I have tried using this plugin on ios under the version 4.26.0.

What has been going on is that it is supposed to open a webview asking if the user would like to proceed with the facebook app installed or login with phone or email.

What is happening now is that the open with phone or email (Webview) is being shown without the option to open the facebook app.

I already setted up the behavior to system account

LoginManager manager = new LoginManager();
manager.LoginBehavior = LoginBehavior.SystemAccount;

Any one have been throught this?
Any solving?

I get this exception when trying to call

var result = await loginManager.LogInWithReadPermissionsAsync(Constants.Constants.FacebookPermissions, vc);

I am using version 4.27.1, and according to the Getting Started article here:

It should only be necessary to add the following:
