You can convert JSON to Java Object.

class A{
        private  String mode;
        private B raw;
        ...
    }
    class B{
        private String service_provider;
        private List<C> data;
        ...
    }
    class C{
        private String v_id;
        private List<D> gpsData;
        ...
    }
    class D{
        private double lat;
        ...
    }

You can use json2csharp. It will help you to convert json objects to pojo

For example the conversion of your json will be:

// import com.fasterxml.jackson.databind.ObjectMapper; // version 2.11.1
// import com.fasterxml.jackson.annotation.JsonProperty; // version 2.11.1
/* ObjectMapper om = new ObjectMapper();
Root root = om.readValue(myJsonString), Root.class); */
public class GpsData{
    public double lat;
    public double lon;
    public String sts;
    public String loc;
    public int spd;
    public String c_nm;
    public String b_nm;
    public String b_id;
    public String v_no;
    public String v_tp;
    public String speed_unit;
    public String time_inMillis;
    public String time;
    public String ign;
    public boolean gps;
    public String _id;
}

public class Datum{
    public String v_id;
    public ArrayList<GpsData> gpsData;
}

public class Raw{
    public String service_provider;
    public ArrayList<Datum> data;
    public String language;
}

public class Options{
    public Raw raw;
}

public class Root{

    public Raw raw;
    public Options options;
