Retrofit POJO empty

Question

Can anyone see why my s.getSymbol() error returns null in this code?

The json prints to the terminal fine and there are no runtime errors when creating the 'quote'.

However trying to access it's members throws a null pointer.

Do I need to include all nodes of the JSON in my POJO? For instance if I only wanted the Symbol could I only have that data member as long as it's setter and getter?

Thank you

Answer 1

http://www.jsonschema2pojo.org/ generated the following (shortened) POJOS, that should be parseable:

public class ResultWrapper {
Query query;
(...)
}

public class Query {

private Integer count;
private String created;
private String lang;
private Results results;

(...)
}

public class Results {

// you might wanna make this an array in your json and a List here
private Quote quote;
(...)

}

public class Quote {

private String symbol;
private String Ask;
private String AverageDailyVolume;
private String Bid;
private String AskRealtime;
private String BidRealtime;
private String BookValue;
private String ChangePercentChange;
private String Change;
private Object Commission;
private String Currency;
private String ChangeRealtime;
private String AfterHoursChangeRealtime;
private String DividendShare;
private String LastTradeDate;
private Object TradeDate;
private String EarningsShare;
private Object ErrorIndicationreturnedforsymbolchangedinvalid;
private String EPSEstimateCurrentYear;
private String EPSEstimateNextYear;
private String EPSEstimateNextQuarter;
private String DaysLow;
private String DaysHigh;
private String YearLow;
private String YearHigh;
private String HoldingsGainPercent;
private Object AnnualizedGain;
private Object HoldingsGain;
private String HoldingsGainPercentRealtime;
private Object HoldingsGainRealtime;
private String MoreInfo;
private Object OrderBookRealtime;
private Object MarketCapitalization;

private String LastTradeRealtimeWithTime;

private Object HoldingsValueRealtime;
private String YearRange;
private String DaysValueChange;
private String DaysValueChangeRealtime;
private String StockExchange;
private Object DividendYield;
private String PercentChange;

(...)
}

Then modify your retrofit interface to

public interface StockApiInterface {
        @GET("/yql?q=select%20*%20from%20yahoo.finance.quotes%20where%20symbol%20in%20(\"AIB.IR\")%0A%09%09&format=json&diagnostics=false&env=http%3A%2F%2Fdatatables.org%2Falltables.env&callback=")                               
                 ResultWrapper listQuotes();
}

You can now access the quote with:

ResultWrapper result = RetrofitInterface.getStockApiClient().listQuotes();
Quote q = q.getQuery().getResults().getQuote();

I think you need to parse this model :

public class query {
   int count;
   String created;
   String lang;
   Quote results;
   .
