Android Facebook SDK中的FeedDialog不起作用

Question

我正在嘗試使用FeedDialog在Facebook上發布消息。
參考： http : //developers.facebook.com/docs/howtos/androidsdk/3.0/feed-dialog/

碼：

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");


    FeedDialogBuilder builder = new FeedDialogBuilder(getActivity(), Session.getActiveSession(), params);
    builder.setOnCompleteListener(new OnCompleteListener() {

        @Override
        public void onComplete(Bundle values, FacebookException error) {

            if (error != null) {
                Log.d(TAG, "FeedDialog Error : "+error.getMessage());
            }

            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(getActivity(),"Posted story, id: "+postId,Toast.LENGTH_SHORT).show();
                } else {
                    // User clicked the Cancel button
                    Toast.makeText(getActivity().getApplicationContext(), "Publish cancelled",Toast.LENGTH_SHORT).show();
                }
            } else if (error instanceof FacebookOperationCanceledException) {
                // User clicked the "x" button
                Toast.makeText(getActivity().getApplicationContext(), "Publish cancelled", Toast.LENGTH_SHORT).show();
            } else {
                // Generic, ex: network error
                Toast.makeText(getActivity().getApplicationContext(), "Error posting story",Toast.LENGTH_SHORT).show();
            }
        }
    });

    builder.build().show();

}

按鈕onClickListener：

publishButton.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            publishFeedDialog();

        }
    });

當我單擊“發布”按鈕時，顯示一個等待對話框，一段時間后該對話框Toast ，我Toast說"Error posting story" ，為什么？

logcat的

D/FacebookSDK.WebDialog(3572): Webview loading URL:

當我在瀏覽器中打開上面的鏈接時，它會工作並顯示“張貼到牆上”對話框，例如

D/MainFragment(3150): {Response:  responseCode: unknown, graphObject: null, error: {HttpStatus: -1, errorCode: -1, errorType: null, errorMessage: null}, isFromCache:false}

D/MainFragment(3150): FeedDialog Error : Couldn't find the URL.

這是來自Facebook開發人員頁面，我已經用過了。 就我而言，它有效。 你應該嘗試這樣：

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(getActivity(),
            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(getActivity(),
                            "Posted story, id: "+postId,
                            Toast.LENGTH_SHORT).show();
                    } else {
                        // User clicked the Cancel button
                        Toast.makeText(getActivity().getApplicationContext(), 
                            "Publish cancelled", 
                            Toast.LENGTH_SHORT).show();
                    }
                } else if (error instanceof FacebookOperationCanceledException) {
                    // User clicked the "x" button
                    Toast.makeText(getActivity().getApplicationContext(), 
                        "Publish cancelled", 
                        Toast.LENGTH_SHORT).show();
                } else {
                    // Generic, ex: network error
                    Toast.makeText(getActivity().getApplicationContext(), 
                        "Error posting story", 
                        Toast.LENGTH_SHORT).show();
                }
            }

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

仔細看看這部分：

WebDialog feedDialog = (new WebDialog.FeedDialogBuilder(getActivity(),

但是你用過

FeedDialogBuilder builder = new FeedDialogBuilder(getActivity(),

我認為問題就在這里。
