您正试图在当前代码中的主UI线程上执行网络操作。所以，避免UI挂起和应用程序崩溃使用

将所有facebook网络操作代码放入

doInBackground

中，并将所有更新UI内容的代码放入

AsyncTask

的

onPostExecute

中，以避免“不幸的是，AppName已停止。”消息您可以在授权方法之前添加这些代码行

StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);

尝试你的应用程序超越蜂巢。在3.0以下的较低版本中，它不会显示此异常。在2.2或2.3上尝试它，它会起作用。

将对您有所帮助。

它不会无缘无故地停止。。。读logcat logcat logcat说什么？你的网络视图代码是什么？
