AsyncTask и RuntimeException в doInBackground

Question

Ошибка возникает, когда она вызывает две функции connecttask и connecttaskproperty. Если вы только вызываете connecttask, он работает. Может ли кто-нибудь помочь?

частный класс DelayedTask расширяет TimerTask {

@Override 
    public void run() { 
     String url = "..."; 
     Log.i("Tag","Timer Task executing"); 

     // code for updating sqlite database 
     try { 

      int k = db.getReportsCount(); 
      Log.d("send0","getReports"); 
      for(int i = 1; i < k+1; i++){ 
       Log.d("send2","getReports"); 
       Report report = new Report(); 
       report = db.getReport(i); 
       Log.d("send1","getReport"); 
       int posted; 
       posted = report.getPosted(); 
       Log.d("send", String.valueOf(posted));

Answer 1

doPostProperty(Map<Integer,Report> localHashmap){ 

    String url = "..."; 
} 

, если вы передаете неверное значение URL-адреса, как вы получите результат?
