                        }

        callbackManager = CallbackManager.Factory.create();
        manager = LoginManager.getInstance();
        manager.logInWithPublishPermissions(
                NextActivity.this,

    }

    private void sharePhotoToFacebook(){

        try{

            Bitmap bm = ((BitmapDrawable)image.getDrawable()).getBitmap();

            SharePhoto photo = new SharePhoto.Builder()
                    .setBitmap(bm)
                    .setCaption("BMW Vision")

                    .build();

            SharePhotoContent content = new SharePhotoContent.Builder()
                    .addPhoto(photo)
                    .build();

            
            ShareApi.share(content, new FacebookCallback<Sharer.Result>() {
                @Override
                public void onSuccess(Sharer.Result result)
                {
                    System.out.println("sammy_publish_result "+result);
                    Toast.makeText(NextActivity.this, "Success in Posting", Toast.LENGTH_SHORT).show();
                }

                @Override
                public void onCancel()
                {
                    System.out.println("sammy_shareapi_canceled");
                }

                @Override
                public void onError(FacebookException e)
                {
                    System.out.println("sammy_shareapi_exception "+e);
                }
            });
            


        }catch (Exception e){
            System.out.println("sammy_exception "+e.toString());
        }

    }


    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        callbackManager.onActivityResult(requestCode, resultCode, data);
    }

}

我正在尝试在后台将图像和文本分享到 Facebook。首先，我检查发布权限是否已被授予。如果不是，我将使用 logInWithPublishPermissions 获取发布权限。但出于某种原因，registerCallback 的响应总是出现在 onCancel() 中。我需要向 logInWithPublishPermissions 添加什么吗？

您必须在 Facebook 开发者网站上授予 publish_actions 权限 https://developers.facebook.com/

请关注link设置您的应用以获取 publish_actions 权限并提交您的应用以供审核。
