如何正确地发出android HttpGet请求

我正在尝试从android向后端Django服务器发出get请求。每次我发出请求时都会引发异常，并且服务器没有显示已与之联系。我怎样才能正确地做到这一点？谢谢

以下是我的尝试：

客户端android：

try{

        URI website = new URI(URL);
        //Request to server
        HttpGet httpget = new HttpGet();
        httpget.setURI(website);
        HttpResponse response = Client.execute(httpget);
        Log.d("EXECUTED",response.toString());
    }catch (Exception ex){
        textView.setText("Fail");
    }

服务器端Django：

def app(request, id):
      context = RequestContext(request)

      fab_categories = Catagories.objects.all()

      return HttpResponse("worked")

根据要求，以下是日志：

我还向清单添加了相应的权限。

您好：）我正在开发一个类似的应用程序，我遵循了本教程

很抱歉在这里删除了一个链接，但它是非常不言自明的，并且代码有很好的文档记录

忽略标题，查看InboxActivity.java代码

什么异常？“例外”太宽泛了。。可能是您从未访问服务器、端口错误、url错误等。。让我们看看你的StackTrace我指的是捕获声明。它在Client.execute函数之后立即失败。我添加了程序的日志。谢谢你的回复。实际上我刚刚解决了这个问题：）。问题是我是从onCreate内部发出请求的。我创建了一个异步类，然后从onCreate实例化了它。
