我开发了一款在FB上分享视频的游戏，之前运行良好，但我不知道现在我是如何得到这个错误的。我也获得了所有的许可，现在它没有给我任何许可。 在FB RequestAsyncTask类中，我对AlertDialog做了一些修改，显示了上传视频的过程。
这是我执行AsyncTask
的地方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任何其他部分，请告诉我我会给你。我需要调试并上传到Google Play
修改
这里是整个代码，我使用fb post，将项目更换为新的后它正在工作但是我在FB Developer上更改应用程序名称之后它会问正常的权限然后再开始给我同样的错误

答案 0 :(得分：11)
AsyncTask只能执行一次。你在代码中的其他地方调用执行程序吗？
答案 1 :(得分：9)
类AsyncTask的实例只能执行一次。因此，每次调用execute（）时都必须创建新实例。
new ClassName().execute();
答案 2 :(得分：2)
您可以通过新的CLASS_NAME（）多次使用AsyncTask。执行（） CLASS_NAME扩展了AsyncTask，没有来自CLASS_NAME的创建实例
答案 3 :(得分：-1)
只需在异步任务线程池
中执行Async任务即可new RequestAsyncTask(Result.this,
new Request(session, "me/videos", postParam, HttpMethod.POST, callback))
.executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR);
