Please help me to solve this.

Try to remove the "?" in the request. Retrofit manages the query params. — Federico De Gioannini, Jul 03 '16 at 10:56
Where can i find it?I think above logcat is retrofit debug log.. — Mohit Gaur, Jul 03 '16 at 11:18
I guess error is because of this line `Call> call = alfa.meaning(api_key,word);` this should be like `Call> call = alfa.meaning(word,api_key);` — Murli Prajapati, Jul 03 '16 at 11:18
Set loglevel to Full in your retrofit configuration. So we can check if the url is correct. — Federico De Gioannini, Jul 03 '16 at 11:46
Thank u all it is now working,my mistake was in base url..I have changed my base url from Retrofit retrofit=new Retrofit.Builder().baseUrl("http://api.wordnik.com/v4/") to Retrofit retrofit=new Retrofit.Builder().baseUrl("http://api.wordnik.com/") and my end point from @GET("/word.json/{word}/definitions") to @GET("/v4/word.json/{word}/definitions") — Mohit Gaur, Jul 03 '16 at 11:52

from the JSON response got from your api, try changing the pojo to the one below -

public class Dictionary {
    private List<Object> textProns = new ArrayList<Object>();
    private String sourceDictionary;
    private List<Object> exampleUses = new ArrayList<Object>();
    private List<Object> relatedWords = new ArrayList<Object>();
    private List<Object> labels = new ArrayList<Object>();
    private List<Object> citations = new ArrayList<Object>();
    private String word;
    private String partOfSpeech;
    private String attributionText;
    private String sequence;
    private String text;
    private Double score;

    public List<Object> getTextProns() {
    return textProns;
    }

    public void setTextProns(List<Object> textProns) {
    this.textProns = textProns;
    }

    public String getSourceDictionary() {
    return sourceDictionary;
    }

    public void setSourceDictionary(String sourceDictionary) {
    this.sourceDictionary = sourceDictionary;
    }

    public List<Object> getExampleUses() {
    return exampleUses;
    }

    public void setExampleUses(List<Object> exampleUses) {
    this.exampleUses = exampleUses;
    }

    public List<Object> getRelatedWords() {
    return relatedWords;
    }

    public void setRelatedWords(List<Object> relatedWords) {
    this.relatedWords = relatedWords;
    }

    public List<Object> getLabels() {
    return labels;
    }

    public void setLabels(List<Object> labels) {
    this.labels = labels;
    }

    public List<Object> getCitations() {
    return citations;
    }

    public void setCitations(List<Object> citations) {
    this.citations = citations;
    }

    public String getWord() {
    return word;
    }

    public void setWord(String word) {
    this.word = word;
    }

    public String getPartOfSpeech() {
    return partOfSpeech;
    }

    public void setPartOfSpeech(String partOfSpeech) {
    this.partOfSpeech = partOfSpeech;
    }

    public String getAttributionText() {
    return attributionText;
    }

    public void setAttributionText(String attributionText) {
    this.attributionText = attributionText;
    }

    public String getSequence() {
    return sequence;
    }

    public void setSequence(String sequence) {
    this.sequence = sequence;
    }

    public String getText() {
    return text;
    }

    public void setText(String text) {
    this.text = text;
    }

    public Double getScore() {
    return score;
    }

    public void setScore(Double score) {
    this.score = score;
    }
}

Theres a great site called http://www.jsonschema2pojo.org/ which can help u with the generation of POJO's.

Alright...I dint see you're solution when posting the answer. My Bad! — niranjan_b, Jul 03 '16 at 12:12
