主线程异常上的android os网络

Question

我让这段代码在单个应用程序中工作，但如果加入其他应用程序，则显示此对话框“主线程异常上的 android 操作系统网络”

           }




      });

      }   
}

允许我激活 <uses-permission android:name="android.permission.INTERNET"/> 仍然无法正常工作

您需要在独立于主 (UI) 线程的线程上运行互联网 Activity ，您可以通过将代码包装在以下 block 中来实现:

new Thread() {
    @Override
    public void run() {
       //your code here
    }
}.start();
