我可以從我的活動發送價值廣播接收器，但我不能長時間使用它

Question

實際上在我的應用程序我想發送消息時，我的手機打任何電話......這裏的應用程序安裝時間問父母號碼和它的號碼從我的第一次活動發送到廣播接收器的活動......它在那裏接收並烘烤價值......但是當我撥打電話時它的值變爲空......任何人都可以幫助我訪問那個值手機通話時間..是有可能?? how..thank你我的代碼如下......

在我的第一個活動

發送值廣播接收機：

try 
{ 
    Toast.makeText(getApplicationContext(), "try", Toast.LENGTH_LONG).show(); 

    Intent in = new Intent("my.action.string"); 
    in.putExtra("parent", PARENT);//this string sending to broadcast receiver 
    sendBroadcast(in); 
} 
catch (Exception e) 
{ 
    // TODO: handle exception 
    e.printStackTrace(); 
}   

我的廣播接收器是：

public class myBroadcast extends BroadcastReceiver 
{ 
    String out_number; 
    String myparent; 
    @Override 
    public void onReceive(Context context, Intent intent) 
    { 
     // TODO Auto-generated method stub 
     myparent = intent.getExtras().getString("parent"); //this sting access the number first and then change to null at making phone call 
     final String my=myparent; 
     Toast.makeText(context, "broadcst"+myparent, Toast.LENGTH_LONG).show(); 

     if (intent.getAction().equals("android.intent.action.NEW_OUTGOING_CALL")) 
     { 
      out_number=intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER); 
      Toast.makeText(context, "broadcst"+my+" "+out_number, Toast.LENGTH_LONG).show(); 
      SmsManager sm=SmsManager.getDefault(); 
      sm.sendTextMessage(myparent, "5554", "calling..to"+myparent, null, null); //5554 is my emulator number to check its in emulator 
      Toast.makeText(context, "send"+out_number, Toast.LENGTH_SHORT).show(); 
     } 
    } 
}
