问题描述
我开发了一款可以在FB上共享视频的游戏，该游戏之前运行良好，但是我不知道现在如何得到此错误.另外，我获得了所有许可，但现在没有给我任何许可. 在FB RequestAsyncTask类中，我对AlertDialog进行了一些修改，以显示上传视频的过程.
I developed a game that shares video on FB, it was working well before but I dunno how now I'm getting this error. Also I was getting all permission and now it's not giving me any. And in FB RequestAsyncTask class I made some modifications for AlertDialog that show process of uploading video.
这是我执行AsyncTask的地方
Here is where I'm executing AsyncTask
Request request = new Request(session, "me/videos", postParam, HttpMethod.POST, callback);
RequestAsyncTask reqTask = new RequestAsyncTask(Result.this, request);
reqTask.execute();
和Logcat

如果有人想看看代码的其他部分，请告诉我，我会给你的.我需要尽快对其进行调试，然后上传到Google Play
if anyone wanna look at any other part of code just let me know I'll give you. ASAP I need to debug this and upload to Google Play

这是我正在使用fb post的完整代码，将项目替换为新项目后，它可以正常工作，但是当我在FB Developer上更改应用程序名称后，它询问了正常的权限，然后又开始再次给我同样的错误./p>
here is whole code where I'm using fb post, After replace project into new one it was working but after I change application name on FB Developer it ask permission that is normal then it start to give me same error again.

推荐答案
AsyncTask只能执行一次.您在代码中的其他地方调用执行吗?
An AsyncTask can only be executed once. Are you calling execute somewhere else in your code?
