android - Facebook 分享对话框未打开

Question

根据这个link here ，我已经安装了 SDK 3.2.1 并实现了一个 uiHelper，以及像这样的 FacebookDialog:

if (FacebookDialog.canPresentShareDialog(getApplicationContext(),
            FacebookDialog.ShareDialogFeature.SHARE_DIALOG)) {
        // Publish the post using the Share Dialog
        Toast.makeText(this, "if", Toast.LENGTH_LONG).show();
        FacebookDialog shareDialog = new FacebookDialog.ShareDialogBuilder(
                this).setLink("https://developers.facebook.com/android")
                .build();
        uiHelper.trackPendingDialogCall(shareDialog.present());

    } else {
        Toast.makeText(this, "else", Toast.LENGTH_LONG).show();
        // Fallback. For example, publish the post using the Feed Dialog
        publishFeedDialog();
    }

对于 publishFeedDialog() 我有:

    private void publishFeedDialog() {
    Bundle params = new Bundle();
    params.putString("name", "Facebook SDK for Android");
    params.putString("caption",
            "Build great social apps and get more installs.");
    params.putString(
            "description",
            "The Facebook SDK for Android makes it easier and faster to develop Facebook integrated Android apps.");
    params.putString("link", "https://developers.facebook.com/android");
    params.putString("picture",
            "https://raw.github.com/fbsamples/ios-3.x-howtos/master/Images/iossdk_logo.png");

    WebDialog feedDialog = (new WebDialog.FeedDialogBuilder(this,
            Session.getActiveSession(), params)).setOnCompleteListener(
            new OnCompleteListener() {

                @Override
                public void onComplete(Bundle values,
                        FacebookException error) {
                    if (error == null) {
                        // When the story is posted, echo the success
                        // and the post Id.
                        final String postId = values.getString("post_id");
                        if (postId != null) {
                            Toast.makeText(getApplicationContext(),
                                    "Posted story, id: " + postId,
                                    Toast.LENGTH_SHORT).show();
                        } else {
                            // User clicked the Cancel button
                            Toast.makeText(getApplicationContext(),
                                    "Publish cancelled", Toast.LENGTH_SHORT)
                                    .show();
                        }
                    } else if (error instanceof FacebookOperationCanceledException) {
                        // User clicked the "x" button
                        Toast.makeText(getApplicationContext(),
                                "Publish cancelled", Toast.LENGTH_SHORT)
                                .show();
                    } else {
                        // Generic, ex: network error
                        Toast.makeText(getApplicationContext(),
                                "Error posting story", Toast.LENGTH_SHORT)
                                .show();
                    }
                }

            }).build();
    feedDialog.show();
}

现在 FacebookDialog.canPresentShareDialog 始终为 false，即使在手机中安装了 Facebook 应用程序然后调用 publishFeedDialog() 也是如此。但是应用程序在此之后崩溃了。

解决这个问题的方法是什么？当应用程序在我的手机中时，为什么会显示正常的 facebook 对话框？ (如果有帮助，我正在使用 Lenevo 模型)

您需要更新的 FB 应用程序才能使用共享对话框。确保下载最新的!

此外，不，您不需要登录即可启用共享对话框。
