我正在开发一个Android应用程序，我试图在Facebook墙上发布。问题是，每次通过我的应用程序发布内容而不是发布新帖子时，我的旧帖子都会被新帖子取代。
以下是我的发布代码
private void publishStory(int item)
{
Session session = Session.getActiveSession();
if (session != null)
{
if(Session.getActiveSession() != null)
{
if (session.isOpened())
{
List<String> permissions = session.getPermissions();
if (!isSubsetOf(PERMISSIONS, permissions)) {
Session.NewPermissionsRequest newPermissionsRequest = new Session.NewPermissionsRequest(this, PERMISSIONS);
session.requestNewPublishPermissions(newPermissionsRequest);
return;
}
}
}
else
{
Toast.makeText(SecondScreen.this, "session not active", Toast.LENGTH_LONG).show();
Log.e("session not active","session not active");
}
Bundle postParams = new Bundle();
postParams.putString("name", String.valueOf(item));
postParams.putString("caption", "test2");
postParams.putString("description","I am @ ");
postParams.putString("link", "http://maps.google.com/maps?q="+12+","+7);
postParams.putString("picture", filepath);
Request.Callback callback = new Request.Callback()
{
public void onCompleted(Response response)
{
FacebookRequestError error = response.getError();
if (error != null)
{
Toast.makeText(SecondScreen.this, "FacebookRequestError "+error, Toast.LENGTH_LONG).show();
Log.e("FacebookRequestError","FacebookRequestError "+error);
}
else
{
try
{
Toast.makeText(SecondScreen.this, "successfully posted!!", Toast.LENGTH_LONG).show();
Log.e("successfully posted!!","successfully posted!!");
}
catch (Exception e)
{
Toast.makeText(SecondScreen.this, "Post Unsuccessful 1 !!!", Toast.LENGTH_LONG).show();
Log.e("Post Unsuccessful 1","Post Unsuccessful 1");
}
}
}
};
Request request = new Request(session, "me/feed", postParams, HttpMethod.POST, callback);
RequestAsyncTask task = new RequestAsyncTask(request);
task.execute();
}
}
请帮忙！谢谢！
