Question

根据这个link here，我安装了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();
}

即使在手机中安装了Fb app，然后调用了publishFeedDialog（），FacebookDialog.canPresentShareDialog总是会变为假。但是应用程序在此之后崩溃了。

这是什么解决方案？当我的手机中有应用程序时，为什么会显示正常的Facebook对话框？（我正在使用Lenevo模型，如果有帮助的话）

您需要一个较新的FB应用才能使共享对话框正常工作。确保下载最新版本！

此外，不，您不需要登录即可启用共享对话框。

Facebook Share Dialog未开通
