Question

在我的应用程序中，我尝试使用AbstractPhoneListener跟踪来电。调用被跟踪，但问题是它生成错误，我必须退出模拟器

我在设备上进行了测试但是当一个电话到来时没有任何事情发生，因为我试图做到!!!!

ERROR =“从0x00000004读取访问冲突”

代码：

public class CallTrace extends AbstractPhoneListener
{


    CallTrace()
    {

    }


    public void callIncoming(int callId)
    {
        PhoneCall call = Phone.getCall(callId);
        String callNumber = call.getDisplayPhoneNumber();l

        System.out.println("call traced!!!!!!!!");

    }   

}

代码：

public class BackgroundListener extends Thread 
{  
    private static PersistentObject timeStore,NPZstore;
    private static Vector timeVector,mode;
    static CallTrace calltrace;
    String[] time1,time2;
    int time1Flag=0,time2Flag=0;

     public BackgroundListener()
     {   
         calltrace = new CallTrace();
     Phone.addPhoneListener(calltrace); 
         this.start();
     }
     boolean stopThread = false;

     public void run()
     {
          while (!stopThread)
          {   
        //do some coding here like matching of dates etc.that works well    
               try
               {
                   sleep(6000) ;
               }
               catch (Exception e)
               {
                    System.out.println("exception in background thread:"+e);
               }
          }
     }

     public synchronized void stop()
     {
          stopThread = true;
     }
     protected void onExit()
     {
          this.stop();
     }
  }

代码：

public class HomeScreen extends UiApplication implements GlobalEventListener
{
    private static PersistentObject NPZstore;
    private static Vector mode;
    static boolean modeValue=false;
    static BackgroundListener obj;


    public static void main(String[] args)
    {
        if(args!=null && args[0].equals("gui"))
        {
            HomeScreen homescreen = new HomeScreen();
            homescreen.enterEventDispatcher();
        }
        else
        {
          obj = new BackgroundListener();       
        }
    }
    HomeScreen()
    {
        pushScreen(new WorkScreen());
    }


public void eventOccurred(long guid, int data0, int data1, Object object0,
  Object object1)
        {

    }
}
class WorkScreen extends MainScreen 
{
    CustomButtonField REDbutton,GREENbutton;
    HorizontalFieldManager hfmRED,hfmGREEN;
    private static PersistentObject NPZstore;
    private static Vector mode;
    boolean modeValue=false;
    static CallTrace calltrace;
    PopupScreen selectBluetoothType;
    final Bitmap background2;

    public WorkScreen()
    {
    //adding some fields here   
        }       
}

这看起来像是由模拟器崩溃导致的Windows错误。所以这不是你的代码中的错误，但可能是模拟器中的错误。我建议downloading and installing a different simulator - 即使它是相同的模型选择最新版本。随JDE一起提供的模拟器通常很陈旧。
