带有回调的Facebook SDK 4.0 AppInviteDialog

Question

在新的Fb SDK 4.0 for Android中，您可以根据文档注册LoginButton的回调。 https://developers.facebook.com/docs/facebook-login/android/v2.3

问题是AppInviteDialog也可以吗？或者有没有其他方法来确定App-Invite是否成功？

Answer 1

是的，这是可能的。

public static void openDialogInvite(final Activity activity)
{
    String appLinkUrl, previewImageUrl;

    appLinkUrl = "your app link url";
    previewImageUrl = "https://www.example.com/my_invite_image.jpg";

    if (AppInviteDialog.canShow())
    {
        AppInviteContent content = new AppInviteContent.Builder()
                .setApplinkUrl(appLinkUrl)
                .setPreviewImageUrl(previewImageUrl)
                .build();

        AppInviteDialog appInviteDialog = new AppInviteDialog(activity);
        CallbackManager sCallbackManager = CallbackManager.Factory.create();
        appInviteDialog.registerCallback(sCallbackManager, new FacebookCallback<AppInviteDialog.Result>()
        {
            @Override
            public void onSuccess(AppInviteDialog.Result result)
            {
            }

            @Override
            public void onCancel()
            {
            }

            @Override
            public void onError(FacebookException e)
            {
            }
        });

        appInviteDialog.show(content);
    }
}
