我要在我的Android应用中访问linkedin个人资料。我使用下面的代码，它在Android设备上工作正常，但在模拟器上崩溃。不知道问题出在哪里。我的代码如下。

在onCreate（）中的setContentView（）之后添加以下函数。
if (android.os.Build.VERSION.SDK_INT > 9) {
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build(); StrictMode.setThreadPolicy(policy);
}
这对我有用。希望它能为你效劳。

顺便说一下
将AsyncTask用于后台任务会更好。
