android – 仅当设置了opengraphobject.setproperty(“og：url”)时,Facebook SDK无法为用户生成预览
作者：互联网
我有一个应用程序,我想在Facebook上分享历史记录.我的应用程序没有网页.我只想分享带有标题和描述的图像,如果可以点击共享网站,他们会重定向到谷歌播放下载应用程序或Facebook应用程序页面.
我在大多数facebook样本中寻找答案,这里有一些我肯定做错的事情.
我做了所有的Facebook应用程序配置.关键哈希等…我在开放图形中创建一个名为Publicar a Lugar的历史. Action =“Publicar”Object =“Lugar”.
我有这个代码
private void OpenShareDialog(){
Session session = Session.getActiveSession();
if (session != null) {
// Check for publish permissions
List<String> permissions = session.getPermissions();
if (!isSubsetOf(PERMISSIONS, permissions)) {
pendingPublishReauthorization = true;
Session.NewPermissionsRequest newPermissionsRequest = new Session.NewPermissionsRequest(this, PERMISSIONS);
session.requestNewPublishPermissions(newPermissionsRequest);
return;
}
}
OpenGraphObject oplugar = OpenGraphObject.Factory.createForPost("namespace:lugar");
oplugar.setProperty("og:type","namespace:lugar");
oplugar.setProperty("og:title", LugarCargado.getNombre());
//oplugar.setProperty("og:image", "http://estaticos.sport.es/resources/jpg/2/1/1391546433412.jpg");
//oplugar.setProperty("og:url", "http://www.udg.edu/");
oplugar.setProperty("og:description", LugarCargado.getDescripcion());
//Bitmap bitmap;
//List<Bitmap> bitmaps = new ArrayList<Bitmap>();
//bitmap = BitmapFactory.decodeResource(this.getResources(), R.drawable.icoappfacebook2);
//Log.i(TAG, "Imagen: Height:"+bitmap.getHeight()+ " Width:"+ bitmap.getWidth());
//bitmaps.add(bitmap);
//OpenGraphAction action = GraphObject.Factory.create(OpenGraphAction.class);
OpenGraphAction action = OpenGraphAction.Factory.createForPost("namespace:publicar");
action.setProperty("lugar", oplugar);
action.setType("namespace:publicar");
action.setProperty("previewPropertyName", oplugar);
FacebookDialog shareDialog = new FacebookDialog.OpenGraphActionDialogBuilder(this, action, "lugar")
//.setImageAttachmentsForObject("lugar", bitmaps, true)
//.setImageAttachmentsForAction(bitmaps,true);
.build();
uiHelper.trackPendingDialogCall(shareDialog.present());
}
我在智能手机中调试了两个不同的错误：
1-如果我取消注释其中一行
//oplugar.setProperty("og:image", "http://estaticos.sport.es/resources/jpg/2/1/1391546433412.jpg");
//oplugar.setProperty("og:url", "http://www.udg.edu/");
我有一个错误,上面写着“com.facebook.FacebookException：无法为用户生成预览.”.我不能推动网址
2-如果我想添加自定义图像.如果我取消注释此代码
//Bitmap bitmap;
//List<Bitmap> bitmaps = new ArrayList<Bitmap>();
//bitmap = BitmapFactory.decodeResource(this.getResources(), R.drawable.icoappfacebook2);
//Log.i(TAG, "Imagen: Height:"+bitmap.getHeight()+ " Width:"+ bitmap.getWidth());
//bitmaps.add(bitmap);
和
//.setImageAttachmentsForAction(bitmaps,true);
我有一个黑色的窗口似乎重新启动了……

并显示上一个活动.
使用上面的代码,sharedialog向我展示了facebook对话框,我可以分享.但没有链接,没有我的形象.
你能帮助我吗？我尝试了很多不同的东西！
这是我的智能手机？ facebook版本？
您是否有一个简单的示例来共享自定义(为用户制作)图像以及共享对话框中的描述？
谢谢,抱歉我的英语.
解决方法:
如果您没有Web组件,则不要在og对象中设置URL.如果您设置了一个网址,Facebook会尝试抓取该网址,如果从那里抓取的OG元数据与您提供的内容不匹配,则会失败.
如果要向OG操作添加位图,除了当前正在执行的操作之外,还必须向清单添加NativeAppCallContentProvider.请参阅此处的文档：https://developers.facebook.com/docs/reference/android/current/class/NativeAppCallContentProvider/这是Facebook应用程序实际获取您尝试发送的位图的方式.
最后,看看sdk附带的Scrumptious示例应用程序.它有一个选项(如果你“跳过登录”),它创建一个带有图像附件的新OG对象.
