i'm trying to make a Facebook app invite in Unity on Android platform. I'm currently using Facebook SDK 4.11.0 and Unity 2017.2.0.
The flow here would be:
- Facebook init at app launch
- User press app invite button
- Check if the user has publish_actions and user_friends read/write permissions.
- Ask for login in case the permissions are not granted.
- If success, then make a Facebook app invite through API.
The code of the app invite looks like this:
public void FbAppInvite(string message)
{
FacebookHelper.AuthenticateWithPublishPermissions(new List<string>() { "publish_actions" },
(bool publishSuccess) =>
{
if (publishSuccess)
{
FacebookHelper.AuthenticateWithReadPermissions(new List<string>() { "user_friends" }, (bool success) =>
{
if (success)
{
FB.Mobile.AppInvite(
new System.Uri("https://mycustomurl"),
new System.Uri("https://mycustomimage.png"),
(IAppInviteResult result) =>
{
if (string.IsNullOrEmpty(result.Error)
&& !result.Cancelled)
{
object o;
if (result.ResultDictionary != null
&& result.ResultDictionary.TryGetValue("did_complete", out o))
{
if (o.Equals(true))
{
// Success
}
}
}
}
);
}
});
}
}
);
}
At this point, the app tries to authenticate (which returns success) and finally makes the app invite call. Then the app freezes in a white screen for a couple of seconds and then nothing happens.. the friend dialog never gets displayed. This is the resumed log:

I'm using a test user (configured in app console) loged in facebook app and my real user configured as administrator.
Looks like there is a file vmstat in the device that is trying to open which it does not have permission, don't really know why.
I've tried granting all permissions asked by Facebook app in my device, still no luck.
I'm using the right permissions for this request? The idea is that the user share the app (install) to their friends.
My device is currently at Android 8.1.0. Could this be an issue?
Any ideas?
