Android HTTPGet錯誤

Question

Android新手。嘗試做一個簡單的應用程序來執行一個httpget請求時，按下按鈕的某個網站。按鈕的工作和敬酒工作，但我得到錯誤時，httpget執行。感謝您的幫助....

以下是我有：

package com.example.impdmxcontroller; 

import java.io.IOException; 

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

import android.os.Bundle; 
import android.app.Activity; 
import android.util.Log; 
import android.view.Menu; 
import android.view.View; 
import android.widget.Toast; 

public class MainActivity extends Activity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    } 

    public void Ch1on(View view) throws ClientProtocolException, IOException { 
    Toast.makeText(this, "Ch 1 On!", Toast.LENGTH_SHORT).show(); 
    try { 
     HttpClient client = new DefaultHttpClient(); 
     String getURL = "https://www.google.com"; 
     HttpGet get = new HttpGet(getURL); 
     HttpResponse responseGet = client.execute(get); 
     HttpEntity resEntityGet = responseGet.getEntity(); 
     if (resEntityGet != null) { 
     //do something with the response 
     Log.i("GET RESPONSE",EntityUtils.toString(resEntityGet)); 
     } 
    } catch (Exception e) { 
     e.printStackTrace(); 
    } 
    } 

    public void Ch1off(View view) throws ClientProtocolException, IOException { 
    Toast.makeText(this, "Ch 1 Off!", Toast.LENGTH_SHORT).show(); 
    try { 
     HttpClient client = new DefaultHttpClient(); 
     String getURL = "https://www.google.com"; 
     HttpGet get = new HttpGet(getURL); 
     HttpResponse responseGet = client.execute(get); 
     HttpEntity resEntityGet = responseGet.getEntity(); 
     if (resEntityGet != null) { 
     //do something with the response 
     Log.i("GET RESPONSE",EntityUtils.toString(resEntityGet)); 
     } 
    } catch (Exception e) { 
     e.printStackTrace(); 
    } 
    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
    // Inflate the menu; this adds items to the action bar if it is present. 
    getMenuInflater().inflate(R.menu.main, menu); 
    return true; 
    } 
}

HTTP GET是在主視圖線程。兩種方式來處理它。要麼創建一個新的線程來運行網絡任務，要麼在onCreate（）方法中添加這兩行

StrictMode.ThreadPolicy ourPolicy = new StrictMode.ThreadPolicy.Builder().permitAll().build(); 
     StrictMode.setThreadPolicy(ourPolicy);
