通過服務發佈數據導致應用程序崩潰

功能PostData將數據發送到服務器，但是當我添加它的程序顯示：

不幸的是，程序停止工作

這裏是我的代碼：

package com.yahya.trackingsysem; 
import java.io.IOException; 
import java.util.ArrayList; 
import java.util.List; 

import org.apache.http.NameValuePair; 
import org.apache.http.client.ClientProtocolException;

import org.apache.http.client.methods.HttpPost; 
import org.apache.http.impl.client.DefaultHttpClient; 
import org.apache.http.message.BasicNameValuePair; 

import android.app.Service; 
import android.content.Intent; 
import android.os.Handler; 
import android.os.IBinder; 
import android.widget.Toast; 

public class MyService extends Service { 

    Handler handler=new Handler(); 
    String info; 

    @Override 
    public void onCreate() { 
hello(); 
    } 

    void hello(){ 

     final Runnable r = new Runnable() 
     { 
      public void run() 
      { 
       Toast.makeText(getApplicationContext(), "Starting service", Toast.LENGTH_LONG).show(); 
      //////////////////// 
       postData(); 
      //////////////////// 
       handler.postDelayed(this, 10000); 
      } 
     }; 

     handler.postDelayed(r, 10000); 

    } 

    //********************* فنكشن الارسال 
    public void postData() { 
     // Create a new HttpClient and Post Header 
     HttpClient httpclient = new DefaultHttpClient(); 
     HttpPost httppost = new HttpPost("http://www.webserver.net/tracker.php"); 

     try { 
      // Add your data 
      List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1); 
      nameValuePairs.add(new BasicNameValuePair("name", "Hi")); 
      httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); 

      // Execute HTTP Post Request 
      httpclient.execute(httppost); 

     } catch (ClientProtocolException e) { 
      // TODO Auto-generated catch block 
     } catch (IOException e) { 
      // TODO Auto-generated catch block 
     } 
    } 
    //**************************************** 



    @Override 
    public IBinder onBind(Intent intent) { 
     // TODO Auto-generated method stub 
     return null; 
    } 


}

和堆棧跟蹤：

你不能在線程中使用任何與UI相關的東西，在這裏你會在線程中顯示Toast消息，說明它爲什麼會崩潰。爲此，您必須使用處理程序來顯示吐司消息。

例..

Runnable runnable = new Runnable() { 
      public void run() { 
       Message msg = handler.obtainMessage(); 
       Bundle bundle = new Bundle();     
       bundle.putString("myKey", dateString); 
       msg.setData(bundle); 
       handler.sendMessage(msg); 
      } 
     }; 

private final Handler handler = new Handler() { 

     public void handleMessage(Message msg) { 

      String aResponse = msg.getData().getString("message"); 

      Toast.makeText(getApplicationContext(), ""+msg, Toast.LENGTH_LONG).show(); 

      } 
};

//寫上您的服務類的代碼。

if (android.os.Build.VERSION.SDK_INT > 9) { 
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build(); 
StrictMode.setThreadPolicy(policy); 
}

// Mainfest

<uses-permission android:name="android.permission.INTERNET"/>

我不需要烤麪包，所以我刪除它埠問題仍然相同 – 2014-10-27 10:11:21

你可以發佈錯誤日誌。 – samsad 2014-10-27 10:15:22

我添加了logcat的錯誤 – 2014-10-27 10:19:45

這個問題可能與吐司有關。

刪除TOAST.show（）。

敬酒工作正常，直到我添加的功能踵（）雖然我試圖消除烤麪包，但同樣的問題惜售 – 2014-10-27 09:34:59

你能後的錯誤日誌。 – Akhil 2014-10-27 09:38:26

你可以看到現在的logacat – 2014-10-27 10:17:19
