what error informing? why occur?

i have few cursors in application, , did close them, after work done. error still shows up. reason?

here code :::

private string fetchcontactidfromphonenumber(string phonenumber) {     // todo auto-generated method stub      uri uri = uri.withappendedpath(phonelookup.content_filter_uri,             uri.encode(phonenumber));     cursor cfetch = getcontentresolver().query(uri,             new string[] { phonelookup.display_name, phonelookup._id },             null, null, null);      string contactid = "";       if (cfetch.movetofirst()) {          cfetch.movetofirst();              contactid = cfetch.getstring(cfetch                     .getcolumnindex(phonelookup._id));      }      //system.out.println(contactid);     if(cfetch != null)     {         cfetch.close();     }     return contactid;         }   public uri getphotouri(long contactid) {     contentresolver contentresolver = getcontentresolver();      cursor cursor;     try {         cursor = contentresolver                 .query(contactscontract.data.content_uri,                         null,                         contactscontract.data.contact_id                                 + "="                                 + contactid                                 + " , "                                  + contactscontract.data.mimetype                                 + "='"                                 + contactscontract.commondatakinds.photo.content_item_type                                 + "'", null, null);          if (cursor != null) {             if (!cursor.movetofirst()) {                 return null; // no photo             }         } else {             return null; // error in cursor process         }      } catch (exception e) {         e.printstacktrace();          return null;     }      if(cursor != null)    {        cursor.close();    }      uri person = contenturis.withappendedid(             contactscontract.contacts.content_uri, contactid);     return uri.withappendedpath(person,             contactscontract.contacts.photo.content_directory); } 

this code use cursors. have contentresolver object. should close well?

and finally, impact on error on application, because, doesn't seem interrupt application's execution.
