的Android客戶端的Socket關閉本身

-1

可能重複：
android.os.NetworkOnMainThreadException
Android Socket Client didn’t send and closes itself 的Android客戶端的Socket關閉本身

我是新來的Java和Android編程，我試圖將程序的Android客戶端和服務器我的電腦（Windows 7）。有了這個連接，我想發送一個字符串從PC到Android應用程序，也從應用程序到PC。我檢查了我的服務器，它是否編程正確，是否正確。所以我必須在我的客戶中出現錯誤。當我啓動應用程序。該應用程序啓動，但是當我想從我的應用程序發送一個字符串到PC應用程序只是關閉自己。現在我確實需要你的幫助。我一直在應用程序上編程超過2天。

這是我的LogCat，我真的希望你能告訴我在哪裏可以找到我的錯誤。

鑑於堆棧跟蹤這個異常'android.os.NetworkOnMainThreadExcept離子'我期待着你在主線程中進行網絡活動，而Android似乎並不喜歡這種活動。做一個例外搜索，你一定會發現大批犯了同樣錯誤的人，以及他們如何修復它。 –

好的。謝謝。我會尋找這個。 – Lukas5060

這聽起來像你可能正在做的主界面，而不是像的AsyncTask 後臺網絡的東西這裏是它是如何設置的

public class MyNetworkTask extends AsyncTask<String, String, String> { 
@Override 
protected void onPreExecute() { 
    super.onPreExecute(); 
} 

@Override 
protected void onProgressUpdate(String... values) { 
    super.onProgressUpdate(values); 

} 

@Override 
protected String doInBackground(String... params) { 
//do your work here 
    return something; 
} 

@Override 
protected void onPostExecute(String result) { 
    super.onPostExecute(result); 
     // do something with data here-display it or send to mainactivity

}

這裏一個基本的例子是一個鏈接到它的文檔： http://developer.android.com/reference/android/os/AsyncTask.html
