    Hi All,
    I started getting this error on my Android cloud build recently. (working with Unity 5.6)
    Nothing have been changed in the Facebook sdk, can anyone please give me a hint about how to solve it?

    Here is the colud build log:

    We're also experiencing this error on Unity 5.6. From what we can tell it's because Unity 5.6 introduced the Facebook Game Room build target. If you have that module installed on your build machine it will cause a collision with your existing Facebook SDK, even if you are not targeting the Game Room platform. However, you also can't compile your game if you remove your duplicate Facebook SDK. It seems like the Facebook.Unity namespace is available to all targets if the Game Room module is installed.

    Same here. This is really annoying. Is there any workaround for this? Do I need to reinstall Unity without game room?!

    I've found a workaround..
    1. Close Unity Editor
    2. Remove the Facebook folder in C:\Program Files\Unity\Editor\Data\PlaybackEngines
    3. Remove the FacebookSDK folder in your project's Library folder
    4. Import FacebookSDK
    5. Profit?

    Thanks # blumersolutions, and what about the cloud building is there any solution ?
    has anyone tried the cloud build with 5.6.0p1 or 5.6.0p2 ?

    Cloud build started working for us after we updated our Facebook SDK to 7.9.4. I'm not sure if they fixed something on their end while we were testing since one build failed and then all subsequent builds were fine.

    Unity version is 5.6.0f3. using the same version to build on cloud build. To update the Facebook SDK I just removed the old FacebookSDK folder, imported the new package, and reapplied our settings.

    Not for me, I just imported FB 7.9.4 fresh and then created a new Cloud Build project, and I get the error... Is there anything else you did?

    alright guys here is some updates, after the long battle with the cloud build system,
    i have made some changes as follow:
    * first i updated to FB 7.9.4 as @ESG_Brad said and that worked very well no more already imported error when building for ios.
    * Secondly i rolled back to Unityv 5.6.03 and luckelly for me nothing broke i guess they used the same serialization system between 5.6.03 and 5.6.03p1 or 2
    * Lastly i removed all unresolved errors like undefined objects and hundled most of my exceptions, and removed all extra assets in my project and i've found that some of the build errors where happening due to some # *.dds Textures# and i've learnd that, when i tried to build locally and checked the Console on XCode.

    Moral of the story 5.6.3 works on cloud and locally you have just to clean your project(specially the *.dds files they cause lot of truble when creating materials in ios), handle all exceptions and update your plugins .

    Thanks everybody for your help .

    We are still unable to successfully build, we've upgraded Facebook SDK 7.9.4 and are using 5.6 Latest to build. Builds work on WebGL and iOS, but fail on Android:

    Is there a definite fix for this? Seems like people are randomly tampering with things and eventually getting lucky.

    I think I might have fixed this problem by changing the ProjectSettings.asset file value for "facebookSdkVersion" to "plugin"

    blumersolutions solution's works for me as well.
    When I deleted the Facebook folder from Unity\Editor\Data\PlaybackEngines then unity did not created the file 'Library/FacebookSDK/Facebook.Unity.Settings.dll'.
    Actually it did not created any file related to 'Facebook' i Library folder.

    We're having a similar issue with our jenkins automated builder.
    Seems that building from command line is broken when the Facebook Gameroom module is installed and the Facebook SDK is added to the project, we tested building for both Android and iOS.

    Our solution was to uninstall the Gameroom platform from Unity, delete Library/FacebookSDK folder from the project and rebuild.

    In my case I didn't install the Facebook Gameroom and the problem happens anyway.

    An response from Unity guys? We are currently being unable to build a working FB integration as we are being unable to edit the FacebookSettings.asset

    Tried removing the Facebook folder from PlaybackEngines but same error persists.

    As a workaround, removing the Unity's "native" FacebookSettings.dll from the Library folder seems to do the trick. in mac should be:

    PROJECT_ROOT>Library>FacebookSDK

    I have found that even though I get this error, this is not what makes my build fail.
    My actual reason is a missing dylib link that I need for iOS...

    It seems that cloud build treats this more like a warning and not a critical error.

    A lot of the lack of response from Unity Technologies itself is the fact that Facebook made the Facebook SDK. And, Facebook changes their platform every Sunday. (If you watch the Platform Update stream on Facebook, you'll notice that Facebook regularly breaks their own service.) Their patch day is Wednesday (so from Sunday to Wednesday is a horrible time to try to use Facebook usually)... Having actually talked to people from Facebook, I have the distinct impression that they are great at php, but not so great at other programming languages. (Read: They didn't know their anatomy from holes in the ground, and offered no help even on the simplest of questions.)
    I would imagine that Unity is still waiting to hear back from Facebook, and Facebook is scratching their heads like monkeys.
    Anyway, Same issue here but with Facebook.Unity.Arcade.dll.

    Well, apparently if you remove the dll in Facebook.Unity.Gameroom.dll in \Assets\FacebookSDK\Plugins\Gameroom\Facebook.Unity.Gameroom.dll it also works, since it's now including the one on the Unity install. However, I'm not sure if there's any inconsistence because of the different versions..

    For me iOS is working and Android stopped working a few days ago...
    This seems to be inconsistent.
    Trying to remove the Facebook.Unity.Gameroom.dll and see what happens.

    Yep - made the same change using text editor in ./ProjectSettings/ProjectSettings.asset

    Funny thing is that is was set to
    facebookSdkVersion: 7.10

    then I saved while Unity editor was closed
    facebookSdkVersion: plugin

    But inspecting the file again it has gone back to
    facebookSdkVersion: 7.9.4

    ... since a build.

    Going in to the settings I get a little info area telling me to go in to player settings and set it to 7.10.1
    I think that's what I did when I got in to this mess in the first place.

    Also my app id and upload token also disappeared after making that "facebookSdkVersion: plugin" change.

    So as I've got the thing building and deploying again I'm going to leave it as-is for the moment.

    I didn't see a "plugin" option in the drop-down menu so I suspect when it encounters "plugin" it just resets down to that default 7.9.4 and clears the other settings. Absolutely no proof on that though.

    Pretty shocking the support level from Unity on this issue.
