Java HashMap Error: java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.String

I am fetching HashMap from JSONArray and sending it to SQLite. Its giving me.java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.String. HashMap conversion issue.

The type is HashMap>.

for(int i=0;i<adsarray.length();i++){
      JSONObject obj=adsarray.getJSONObject(i);
      HashMap mapReceivedAdDetails=new HashMap();
      HashMap mapBusinessInfo=new HashMap();



      //mapBusinessInfo.put
      mapReceivedAdDetails.put("RecAdId", obj.getInt("received_ad_id"));
      mapReceivedAdDetails.put("RecBusinessId",obj.getInt("business_id"));
      mapReceivedAdDetails.put("RecBusinessId",obj.getInt("user_id"));
      mapReceivedAdDetails.put("RecAdtitle",obj.getString("received_ad_title"));
      mapReceivedAdDetails.put("RecAdDetail",obj.getString("received_ad_detail"));
      mapReceivedAdDetails.put("RecBusinessZip",obj.getString("business_zip"));
      mapReceivedAdDetails.put("RecBusinessCountry", obj.getString("business_country"));
      mapReceivedAdDetails.put("AdCreated", obj.getString("adreceived_created"));
      mapReceivedAd.put(i, mapReceivedAdDetails);

     //Log.i("ReceivedId",mapReceivedAd.toString());

      mapBusinessInfo.put("BusinessId",obj.getInt("business_id"));
      mapBusinessInfo.put("BusUserId",obj.getInt("user_id"));
      mapBusinessInfo.put("BusName",obj.getString("business_name"));
      mapBusinessInfo.put("BusSt1",obj.getString("business_street1"));
      mapBusinessInfo.put("BusSt2",obj.getString("business_street2"));
      mapBusinessInfo.put("BusCity",obj.getString("business_city"));
      mapBusinessInfo.put("BusState",obj.getString("business_state"));
      mapBusinessInfo.put("BusCountry",obj.getString("business_country"));
      mapBusinessInfo.put("BusZip",obj.getString("business_zip"));
      mapBusinessInfo.put("BusContactNo",obj.getString("business_contactno"));
      mapBusinessInfo.put("BusWebsite",obj.getString("business_website"));
      mapBusinessInfo.put("BusCreated",obj.getString("business_created"));
      mapBusinessDetail.put(i,mapBusinessInfo);
    // Log.i("BusinessDetail",mapBusinessDetail.toString());



     /* ad_business_id=obj.getInt("business_id");
      ad_user_id=obj.getInt("user_id");

      ad_business_country=obj.getString("business_country");*/
      //ad_date_created=obj.getString("date_created");
      //Log.i("+ad_business_id+"+"+ad_user_id+" "+receive_ad_title+" "+receive_ad_detail+" "+ad_business_zip+" "+ad_business_country+" ");
