I am working on an android app in which i send an http response to a server and get a response in string which is in JSON format, now on the basis of this response i need to generate a stacked column chart using AChartEngine for different equipments. The response string looks like as follows

[{"ChartDate":null,"CycleStatus":null,"Cycle_Duration":0,"Cycle_Percent":0,"Duration":0,"EquipmentDescription":"MTConnect","EquipmentId":5,"EquipmentName":"MTC 1","EquipmentStatusColor":null,"EquipmentStatusDescription":null,"EquipmentStatusId":0,"EquipmentStatusIdentifier":null,"EquipmentStatusTypeId":0,"EquipmentStatusTypeName":null,"EquipmentStatusTypeName_resourceKey":null,"EquipmentTimeZoneId":null,"EventData":null,"GeneralStatusState":0,"IsFirstRowData":false,"Percentage":0,"ReportGroupId":0,"ReportGroupName":null,"ReportGroupValue":null,"StatusAction":0,"StatusDuration":[{"ChartDate":null,"CycleStatus":null,"Cycle_Duration":0,"Cycle_Percent":0,"Duration":561.60722222222023,"EquipmentDescription":"MTConnect","EquipmentId":5,"EquipmentName":"MTC 1","EquipmentStatusColor":"#008000","EquipmentStatusDescription":"In Cycle","EquipmentStatusId":0,"EquipmentStatusIdentifier":null,"EquipmentStatusTypeId":1,"EquipmentStatusTypeName":null,"EquipmentStatusTypeName_resourceKey":"EquipmentStatusTypeName.InCycle","EquipmentTimeZoneId":null,"EventData":null,"GeneralStatusState":0,"IsFirstRowData":false,"Percentage":0,"ReportGroupId":0,"ReportGroupName":null,"ReportGroupValue":null,"StatusAction":0,"StatusDuration":null,"TimeStamp":{"DateTime":"\/Date(-62135596800000)\/","OffsetMinutes":0},"UnknownDowntime_Duration":0,"UnknownDowntime_Percent":0},{"ChartDate":null,"CycleStatus":null,"Cycle_Duration":0,"Cycle_Percent":0,"Duration":134.57583333333525,"EquipmentDescription":"MTConnect","EquipmentId":5,"EquipmentName":"MTC 1","EquipmentStatusColor":"#FFFF00","EquipmentStatusDescription":"In Cycle","EquipmentStatusId":0,"EquipmentStatusIdentifier":"","EquipmentStatusTypeId":2,"EquipmentStatusTypeName":null,"EquipmentStatusTypeName_resourceKey":"EquipmentStatusTypeName.UnknownDowntime","EquipmentTimeZoneId":null,"EventData":null,"GeneralStatusState":0,"IsFirstRowData":false,"Percentage":0,"ReportGroupId":0,"ReportGroupName":null,"ReportGroupValue":null,"StatusAction":0,"StatusDuration":null,"TimeStamp":{"DateTime":"\/Date(-62135596800000)\/","OffsetMinutes":0},"UnknownDowntime_Duration":0,"UnknownDowntime_Percent":0}],"TimeStamp":{"DateTime":"\/Date(-62135596800000)\/","OffsetMinutes":0},"UnknownDowntime_Duration":0,"UnknownDowntime_Percent":0},{"ChartDate":null,"CycleStatus":null,"Cycle_Duration":0,"Cycle_Percent":0,"Duration":0,"EquipmentDescription":null,"EquipmentId":1,"EquipmentName":"PCS Loop 1","EquipmentStatusColor":null,"EquipmentStatusDescription":null,"EquipmentStatusId":0,"EquipmentStatusIdentifier":null,"EquipmentStatusTypeId":0,"EquipmentStatusTypeName":null,"EquipmentStatusTypeName_resourceKey":null,"EquipmentTimeZoneId":null,"EventData":null,"GeneralStatusState":0,"IsFirstRowData":false,"Percentage":0,"ReportGroupId":0,"ReportGroupName":null,"ReportGroupValue":null,"StatusAction":0,"StatusDuration":[{"ChartDate":null,"CycleStatus":null,"Cycle_Duration":0,"Cycle_Percent":0,"Duration":495.61333333332925,"EquipmentDescription":null,"EquipmentId":1,"EquipmentName":"PCS Loop 1","EquipmentStatusColor":"#008000","EquipmentStatusDescription":"In Cycle","EquipmentStatusId":0,"EquipmentStatusIdentifier":null,"EquipmentStatusTypeId":1,"EquipmentStatusTypeName":null,"EquipmentStatusTypeName_resourceKey":"EquipmentStatusTypeName.InCycle","EquipmentTimeZoneId":null,"EventData":null,"GeneralStatusState":0,"IsFirstRowData":false,"Percentage":0,"ReportGroupId":0,"ReportGroupName":null,"ReportGroupValue":null,"StatusAction":0,"StatusDuration":null,"TimeStamp":{"DateTime":"\/Date(-62135596800000)\/","OffsetMinutes":0},"UnknownDowntime_Duration":0,"UnknownDowntime_Percent":0},{"ChartDate":null,"CycleStatus":null,"Cycle_Duration":0,"Cycle_Percent":0,"Duration":200.56972222222623,"EquipmentDescription":null,"EquipmentId":1,"EquipmentName":"PCS Loop 1","EquipmentStatusColor":"#FFFF00","EquipmentStatusDescription":"In Cycle","EquipmentStatusId":0,"EquipmentStatusIdentifier":"","EquipmentStatusTypeId":2,"EquipmentStatusTypeName":null,"EquipmentStatusTypeName_resourceKey":"EquipmentStatusTypeNam

Now this is a response for five different equipments and how can i use this JSON string to an array so that i can extract the data of each equipment and send it to AChartEngine for drawing of chart?

    You can convert the response string to JSONObject. The response you posted is JSONArray.

         JSONArray jsonArray = new JSONArray(responseString);
     int size = jsonArray.length();
     ArrayList<JSONObject> arrayList = new ArrayList<JSONObject>();
     for(int i= 0; i< size; i++) {
          JSONObject jsonObject = jsonArray.optJSONObject(i);
          // use this jsonObject to get the value by passing the keys.
           String value = jsonObject.optString(key);

           //here is your array list of jsonobjects
           arrayList.add(jsonObject);
     }
