Eclipse不会在华硕eee TF101上调试

时间：2012-02-14 14:49:28

标签： android eclipse adb

我有一个应用程序，我正在尝试在我的ASUS eee TF101 （没有root）上进行调试，但它无法正常工作。每当我在Esclipse中单击“debug”时，我的ASUS会显示“应用程序....已经意外停止。请再试一次。”错误信息。我可以在我的EVO（root）和DroidX（非root）上运行它，没有任何问题。我已确保所有适用的设置都已应用（Setting up a Device for Development），但它仍然无效。奇怪的是，如果我在onCreate事件的第二行代码上放置一个断点，它甚至不会在那里中断：

boolean bNetworkConnected = true;

我认为一个简单的赋值语句可以用于断点，但它不会在那里中断。

关于发生了什么的任何想法？

更新

Maxim，我也无法在发布模式下运行它。我确保MainActivity是清单文件中指定的那个（记住，这在我的evo和droidx上运行）。当我在发布模式下运行时，这是LogCat的副本：

似乎它在方法GetStringFromWebService上出错了。但奇怪的是这个......直到MainActivity中的调用才进行调用...上面的我的赋值调用（bNetworkConnected = true）是第二行代码，就在super.onCreate（savedInstance）之后。 ..所以它甚至看不到我在那里设置的断点。

    creator.open();

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

    creator.close();
 }

LoadWithNetworkConnectivity代码： 

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";
    DBVersion = GetIntFromWebService(NameSpace, MethodName, SoapAction, URL, "ApplicationName", "AndroidApp");

    //Write DBVersion to Preferences.
    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代码： 

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代码： 

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();
       }
   }
}

有你要求的代码....简而言之，应用程序启动，检查是否有有效的网络连接（在这种情况下，我只是放了一个bool标志，所以我不必继续拔掉我的电缆或断开我的wifi使其工作/不工作），它运行适当的方法。我将标志设置为true，因此它调用LoadWithNetworkConnectivity（）方法....此方法转到我们的.NET Web服务并获取应用程序标题，DBVersion和OpenIssues。在此方法中，它然后调用“GetLatestData”方法并将XML解析为我创建的Issue对象。再一次，所有这些都可以在模拟器，evo和droidx上找到，而不是我的华硕平板电脑。

更新＃2 - 解决方案

我试图让我的平板电脑进行调试并为3.2操作系统创建了一个模拟器（我以前在2.3.3模拟器上运行它）。所以现在我可以调试并查看错误的来源。它似乎在以下行中出错：

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

如果我把它放在一个字符串中，它返回null，我在LogCat中得到的错误是：

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

就像Maxim说的那样，你必须将网络内容放在它自己的线程上。 Android SDK文档也解释了它NetworkOnMainThreadException。它在那里所说的不真实...它可以在旧平台上使用，但不能在Honeycomb及以上版本上运行，这就是华硕平板电脑正在运行的原因，这就是错误即将发生的原因。

感谢Maxim帮助我！一旦我得到代码将网络事件放在它自己的线程上，我将尝试更新这篇文章，以便其他人知道。

2 个答案:

答案 0 :(得分：1)

从您的LogCat错误中说出可以隐藏问题的地方。

  1. 无法启动活动ComponentInfo {com.adacel.app/com.adacel.app.MainActivity}：java.lang.NullPointerException，这意味着您将某个null作为对象获取并尝试从中获取某些内容空值。

  2. 另外ERROR-（5934）：java.lang.RuntimeException：java.lang.NumberFormatException：无效的int：“null”。

  3. NetworkOnMainThreadException（网络调用在主线程中完成）

    4. 首先要确保WebService调用是在一个单独的线程中完成的，因为（NetworkOnMainThreadException）。其次，您从服务中获取正确的数据。查看LoadWithNetworkConnectivity（）

    内部

答案 1 :(得分：0)

在我看来，您已经在设备上安装了相同应用程序的APK。更糟糕的是，如果你通过市场做到了。你应该简单地卸载APK。顺便说一下，你忘了把Manifest放在这里。
