Eclipse將不會在華碩Eee TF101

Question

調試我已經得到了我想要在我的華碩Eee TF101 （不根植）調試應用程序，它不工作。每當我在Esclipse中點擊「調試」，我的華碩顯示「應用程序....意外停止，請重試。」錯誤信息。我能夠在沒有任何問題的情況下在我的EVO（rooted）和DroidX（無根）上運行此操作。我已經確認所有適用的設置已被應用（Setting up a Device for Development），但它仍然不起作用。奇怪的部分是，如果我把一個斷點的代碼onCreate事件二號線，它甚至不破有：

boolean bNetworkConnected = true; 

我想出一個簡單的賦值語句會爲斷點工作，但它不」在那裏打破。

關於發生了什麼的任何想法？

UPDATE

馬克西姆，我不能在釋放模式無論是運行它。我已經確定MainActivity是清單文件中指定的MainActivity（請記住，它在我的evo和droidx上運行）。下面是logcat的副本，當我在釋放模式運行它：

它看起來好像它是在方法GetStringFromWebService示數出來。但奇怪的部分是這個......這個調用是在MainActivity進一步下去之前完成的......我上面的賦值調用（bNetworkConnected = true）是super.onCreate（savedInstance）之後的第二行代碼。這就像它甚至沒有看到我在那裏設置的斷點。

MainActivity代碼

public static final String TAG = "SQLiteDebug";

    creator.open(); 

    //add data to listview through adapter. 
    mListViewIssues.setAdapter(new IssueInfoAdapter(this, creator.queryAll())); 

    creator.close(); 
} 

LoadWithNetworkConnectivity代碼：

private void LoadWithNetworkConnectivity(){ 
    //Set the Titlebar to the stored value in the DB. 
    String SoapAction = "RemoteWebService/GetApplicationTitle"; 
    String MethodName = "GetApplicationTitle"; 
    setTitle(GetStringFromWebService(NameSpace, MethodName, SoapAction, URL, "ApplicationName", "AndroidApp")); 

    //Get the DBVersion. 
    SoapAction = "RemoteWebService/GetDBVersion"; 
    MethodName = "GetDBVersion";

    Editor ePreferences = this.getPreferences(Context.MODE_PRIVATE).edit(); 
    ePreferences.putInt(DBVersionKey, DBVersion); 
    ePreferences.commit(); 

    //Get Issues for this Customer/Location. 
    SoapAction = "RemoteWebService/GetOpenIssues"; 
    MethodName = "GetOpenIssues"; 
    SoapPrimitive xmlData = GetDataFromWebService(NameSpace, MethodName, SoapAction, URL, "ApplicationName", "AndroidApp"); 

    try { 
     GetLatestData(xmlData); 
    } catch (ParserConfigurationException e) { 
     e.printStackTrace(); 
    } catch (SAXException e) { 
     e.printStackTrace(); 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } 

    //Set flag. 
    ConnectedToNetwork = true; 
} 

GetDataFromWebService代碼：

public SoapPrimitive GetDataFromWebService(String NameSpace, String MethodName, String SoapAction, String URL, String argName, String argValue){ 
    try { 
     SoapObject request = new SoapObject(NameSpace, MethodName);   
     HttpTransportSE androidHttpTransport = new HttpTransportSE(URL); 
     SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); 

     envelope.dotNet = true; 

     request.addProperty(argName, argValue); 

     if(MethodName == "GetOpenIssues") 
     { 
      request.addProperty("CustomerCode", "ABC"); 
      request.addProperty("LocationShortName", "KBIF"); 
     } 

     envelope.setOutputSoapObject(request); 
     androidHttpTransport.call(SoapAction, envelope); 

     SoapPrimitive responseData = (SoapPrimitive) envelope.getResponse(); 
     return responseData; 
    } 
    catch (Exception e) { 
     Log.e("GetStringFromWebService ERROR-", new RuntimeException(e).toString()); 
     return null; 
    } 
} 

GetLatestData代碼：

public void GetLatestData(SoapPrimitive xml)throws ParserConfigurationException, SAXException, IOException{ 
    //get the factory 
    DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance(); 

    //Using factory get an instance of document builder 
    DocumentBuilder db = dbf.newDocumentBuilder(); 
    Document doc; 

    //parse using builder to get DOM representation of the XML file 
    InputSource is = new InputSource(new StringReader(xml.toString())); 
    doc = db.parse(is); 

    //Clear out Issues table first. 
    creator = new IssueInfoCreator(this, DBVersion); 
    creator.open(); 
    creator.ClearIssueTable(); 
    creator.close(); 

    NodeList nodes = doc.getElementsByTagName("Table"); 

    for(int i = 0; i < nodes.getLength(); i++) { 
     IssueInfo issue = new IssueInfo(); 

     Element e = (Element)nodes.item(i); 

     issue.setIssueNumber(Long.parseLong(XMLfunctions.getValue(e, "IssueID"))); 
     issue.setIssueSummary(XMLfunctions.getValue(e, "IssueSummary")); 
     issue.setDateReceived(DateFormat.format("MM/dd/yyyy hh:mm:ss", System.currentTimeMillis()).toString()); 

     if(issue.getIssueNumber() > 0 && issue.getIssueSummary() != null){ 
      creator = new IssueInfoCreator(this, DBVersion); 
      creator.open(); 
      creator.InsertIssue(issue.getIssueNumber(), issue.getDateReceived(), issue.getIssueSummary()); 
      creator.close(); 
     } 
    } 
} 

有你的要求....總之代碼，應用程序啓動後，檢查是否有一個有效的網絡連接（在這種情況下，我只是把一個布爾標誌所以我不必拔掉電纜或斷開我的無線網絡以使其工作/不工作），並運行適當的方法。我將該標誌設置爲true，以便它調用LoadWithNetworkConnectivity（）方法....此方法發送到我們的.NET Web服務並獲取應用程序標題，DBVersion和OpenIssues。然後在這個方法中，它調用「GetLatestData」方法並將XML解析爲我創建的Issue對象。再次，所有這些工作都在模擬器，evo和droidx上找到，而不是我的華碩平板電腦。

更新＃2 - 解決方案

我跳過了努力，試圖讓我的平板電腦進行調試並創建了一個模擬器3.2 OS（我之前2.3.3模擬器中運行它）。所以現在我可以調試並查看錯誤來自哪裏。這似乎是第一個錯誤出在下面一行：

setTitle(GetStringFromWebService(NameSpace, MethodName, SoapAction, URL, "ApplicationName", "AndroidApp")); 

如果我把這個字符串，它返回null，我在logcat中得到的錯誤是：

02-14 16:01:21.177: E/GetStringFromWebService ERROR-(510): java.lang.RuntimeException: android.os.NetworkOnMainThreadException 

就像馬克西姆說，你必須把網絡的東西放在它自己的線程上。 Android SDK文檔還解釋了它NetworkOnMainThreadException。不真實的是它在那裏表達......它允許在較老的平臺上，但不能在Honeycomb及以上版本上運行，這就是華碩平板電腦正在運行的，這就是錯誤的原因。

感謝Maxim幫助我！一旦我得到代碼將網絡事件放在它自己的線程上，我會嘗試更新這篇文章，以便其他人知道。

Answer 1

從您的LogCat錯誤說問題可以隱藏的地方。

1. 無法啓動活動ComponentInfo {} com.adacel.app/com.adacel.app.MainActivity：顯示java.lang.NullPointerException，這意味着你得到一個對象某處空，並試圖從東西那個null。

2. 另外ERROR-（5934）：java.lang.RuntimeException：java.lang.NumberFormatException：無效int：「null」。

3. NetworkOnMainThreadException（網絡電話是在主線程中完成的）所有的

首先要在一個單獨的線程中完成確保Web服務調用，因爲（NetworkOnMainThreadException）。其次，您從Service獲得正確的數據。看看LoadWithNetworkConnectivity（）

Answer 2

在我看來，你已經在設備上安裝了相同應用程序的APK。更糟糕的是，如果你是通過市場做到的。你應該簡單地卸載APK。順便說一句，你忘了把Manifest放在這裏。
