我收到错误:

android.os.StrictMode$AndroidBlockGuardPolicy.onNetwork(StrictMode.java:1099).

android.os.StrictMode$AndroidBlockGuardPolicy.onNetwork(StrictMode.java:1099).

我在谷歌上搜索了这个错误并找到了这个链接:DefaultHttpClient to AndroidHttpClient - 这建议我包括在我的 onCreate 方法中使用以下代码.

I googled this error and came upon this link: DefaultHttpClient to AndroidHttpClient - which suggested I include the following code in my onCreate method.

if (android.os.Build.VERSION.SDK_INT > 9) {
  StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
  StrictMode.setThreadPolicy(policy);
}

现在可以工作了.事实上，Android 不再让网络操作在主线程上进行.

Now its working. In fact, Android does not let network operations be performed on the main thread any longer.
