Android Web服務連接錯誤

我創建了java soap web服務並嘗試將其與android app連接。我創建了一個表im數據庫作爲登錄並給出fields.The問題是我的android應用程序代碼不connectctimg並獲取數據。它顯示沒有錯誤的xml登錄頁面os加載，但在按鈕沒有動作。如果我檢查logcat沒有錯誤。我已經發布的代碼和logcat請儘快幫我。Android Web服務連接錯誤

請將您的所有網絡資料放在自己的主題中。例如。 AsyncTask查看一些內容：http://developer.android.com/training/basics/network-ops/connecting.html –

您是否包含Internet權限？ – ZealDeveloper

@ZealDeveloper雅我做到了 –

你需要檢查你所有的logcat.First包括 - Log.i("MyApp", e.getMessage()); in your catch and then you see the error and post your logcat to see what error you get

顯然你沒有看到任何錯誤，因爲你沒有在catch子句中的任何代碼。要看到可能出現的錯誤的詳細說明修改代碼以這種方式（添加logcat的過濾器MyApp的在DDMS）：

try { 
     androidHttpTransport.call(SOAP_ACTION, envelope); 
     SoapPrimitive response = (SoapPrimitive)envelope.getResponse(); 

     TextView result = (TextView) findViewById(R.id.tv_status); 
     result.setText(response.toString()); 

} 
catch(Exception e){ 
     Log.i("MyApp", e.getMessage()); 
}

..ya感謝那個大錯誤..以及我糾正它，現在它顯示錯誤「http請求失敗」 –

請不要那樣做

catch(Exception e){ 

     }

您的logcat是空的，因爲那

您可以使用

catch (Exception ex) { 
    ex.printStackTrace(); 
}

，而不是

不要忘記添加權限來訪問互聯網，您的清單
檢查參數情況是否與 Web服務中的參數情況相同
檢查您是否已將您的庫路徑添加到buil.gradle
