java - Android HTTP GET 错误

Question

对不起，我是 java 和 android 的新手。我想了解为什么它总是响应错误。谢谢!

try {
            HttpClient client = new DefaultHttpClient();  
            String getURL = "http://www.google.com";
            HttpGet get = new HttpGet(getURL);
            HttpResponse responseGet = client.execute(get);  
            HttpEntity resEntityGet = responseGet.getEntity();  
            if (resEntityGet != null) {  
            Toast.makeText(getApplicationContext(), "ok", Toast.LENGTH_LONG).show();
             }
    } catch (Exception e) {
        //e.printStackTrace();
        Toast.makeText(getApplicationContext(), "error", Toast.LENGTH_LONG).show();
    }

导入

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.DefaultHttpClient;

是的，我进入了互联网许可

您似乎正试图在UI 线程 中发出http 请求。

将您的请求放在另一个线程中。
