android - 从 Facebook 链接打开应用程序

Question

我正在开发一个在 facebook 上分享一些信息的应用程序。为此，我这样做:

if (FacebookDialog.canPresentShareDialog(getApplicationContext(), 
            FacebookDialog.ShareDialogFeature.SHARE_DIALOG)) {
    // Publish the post using the Share Dialog
        FacebookDialog shareDialog = new FacebookDialog.ShareDialogBuilder(this)
        .setName(attraction.getName())
        .setLink("http://developer.neosperience.com/")   
        .setDescription(attraction.getDescription())
        .setRef(String.valueOf(id_attraction))
        .setPicture(pictureURLtoShare)
        .build();
        uiHelper.trackPendingDialogCall(shareDialog.present());
    }

我的问题是我需要发送一个参数 (id_attraction)，因此当点击来自 Facebook 的帖子时，它会打开我的应用程序并且我会收到该参数。我认为 setRef 会起作用，但我收到 null。这就是我收到 Intent 的方式:

AppLinkData appLinkData = AppLinkData.createFromActivity(this);
if (appLinkData != null) {
    Bundle arguments = appLinkData.getArgumentBundle();
    //appLinkData.
    if (arguments != null) {
        String targetUrl = arguments.getString("target_url");
        if (targetUrl != null) {
          Log.i("Activity FB", "Target URL: " + targetUrl);
        }
    }
}

我不知道这样做是否正确，但我找到了解决方法。我使用“？”发送附加到 url 的参数所以一切都在右边？将被浏览器忽略。

if (FacebookDialog.canPresentShareDialog(getApplicationContext(), 
            FacebookDialog.ShareDialogFeature.SHARE_DIALOG)) {
    // Publish the post using the Share Dialog
        FacebookDialog shareDialog = new FacebookDialog.ShareDialogBuilder(this)
        .setName(attraction.getName())
        .setLink("http://developer.neosperience.com/?"+id_attraction)   
        .setDescription(attraction.getDescription())
        .setPicture(pictureURLtoShare)
        .build();
        uiHelper.trackPendingDialogCall(shareDialog.present());
    }

然后我像这样收到它:

AppLinkData appLinkData = AppLinkData.createFromActivity(this);
if (appLinkData != null) {
    Bundle arguments = appLinkData.getArgumentBundle();
    //appLinkData.
    if (arguments != null) {
        String targetUrl = arguments.getString("target_url");
        if (targetUrl != null) {
          String[] partOfUrl = targetUrl.split("\\?");
          id_attraction = partOfUrl[1];
          Log.i("Activity FB", "Target URL: " + targetUrl);
        }
    }
