   org.json.JSONException: No value for videoId

Seems like the JSON object doesn’t contain any value/mapping for the parameter "videoId".

To check if the JSON contains a certain key, use has().

Or, you can use optString() to get an empty string if the mapping doesn’t exist.

Here is my JSONObject Code

JSONObject jsonObject = new JSONObject(response);
                    JSONArray jsonArray=jsonObject.getJSONArray("items");
                    for(int i=0;i<jsonArray.length();i++) {
                        JSONObject jsonObject1 = jsonArray.getJSONObject(i);
                        JSONObject jsonVideoId=jsonObject1.getJSONObject("id");
                        JSONObject jsonsnippet= jsonObject1.getJSONObject("snippet");
                        JSONObject jsonObjectdefault = jsonsnippet.getJSONObject("thumbnails").getJSONObject("medium");
                        String videoid=jsonVideoId.getString("videoId");



                        VideoDetails videoDetails=new VideoDetails();
                        videoDetails.setVideoid(videoid);
                        videoDetails.setTitle(jsonsnippet.getString("title"));
                        videoDetails.setDescribtion(jsonsnippet.getString("description"));
                        videoDetails.setUrl(jsonObjectdefault.getString("url"));

                        videoDetailsArrayList.add(videoDetails);

In order to do that I have Generated API key and pasted into my project.
