java - 将数据从Android插入PHP文件，然后插入Mysql错误

Question

我正在使用 Android 应用程序中的一个函数将数据插入到 mysql 数据库中，但每次单击按钮执行它时它都会崩溃。这些是我得到的错误:

这是我的代码

public void insert(){  
    String input_data= "http://www.wolfdoginfo.net/app/dataapp.php"; //URL website anda dengan file insert.php yang telah dibuat  

      HttpClient httpClient = new DefaultHttpClient();  
      HttpPost httpPost = new HttpPost(input_data);  
      ArrayList<NameValuePair> param = new ArrayList<NameValuePair>();  
    final EditText reguser = (EditText) findViewById(R.id.usernamecomplete);
    final EditText regpass = (EditText) findViewById(R.id.passwordcomplete);
    final EditText regemail = (EditText) findViewById(R.id.email);
    String password = regpass.getText().toString();
    password =  md5(password);
      param.add(new BasicNameValuePair("username", reguser.getText().toString()));  
      param.add(new BasicNameValuePair("password", password));  
      param.add(new BasicNameValuePair("email", regemail.getText().toString())); 

      try {  
           httpPost.setEntity(new UrlEncodedFormEntity(param));  
           HttpResponse httpRespose = httpClient.execute(httpPost);  
          HttpEntity httpEntity = httpRespose.getEntity();  
          InputStream in = httpEntity.getContent();  
          BufferedReader read = new BufferedReader(new InputStreamReader(in));  

          String isi= "";  
          String baris= "";  

          while((baris = read.readLine())!=null){  
             isi+= baris;  
          }  

          //Jika isi tidak sama dengan "null " maka akan tampil Toast "Berhasil" sebaliknya akan tampil "Gagal"  
          if(!isi.equals("null")){                    
             Toast.makeText(this, "Berhasil", Toast.LENGTH_LONG).show();  
          }else{  
             Toast.makeText(this, "Gagal", Toast.LENGTH_LONG).show();  
          }  

    } catch (ClientProtocolException e) {  
       // TODO Auto-generated catch block  
       e.printStackTrace();  
    } catch (IOException e) {  
       // TODO Auto-generated catch block  
       e.printStackTrace();  
    }  

}

您需要在单独的线程中发出 HTTP 请求。你会很容易找到一个例子来证明这一点。看看这个:
