Unable to call api using retrofit in android

Earlier i was able to call api using this code and but now it is not working
I'm not sure that what went wrong so if you can help it will be great.
i have uploaded my code files of circulareNotice.java,api.java and Retrofitclient.java
check the code and let me know that what is error and also solution of that error.

In your extractData() method you have the following which implies that you are expecting the service response to be a JSONArray:
JsonArrayRequest jsonArrayRequest = new JsonArrayRequest(Request.Method.GET, ...
If you look at the body of the Exception you will see that the service is returning an object (which contains an array).
{ "count":1154
, "next":"https:\/\/pokeapi.co\/api\/v2\/pokemon?offset=151&limit=151"
, "previous":null
, "results":[ ... some array of values]
... you cut it off so there may be more fields ...
}
As such, it looks like you should accept a JSONObject and then extract the value associated with the results key. I'm not sure on the syntax but probably something like...
JsonObjectRequest request = new JsonObjectRequest(...
#Override
public void onResponse(JSONObject response) {
JSONArray results = response.getJSONArray("results");
....

Use Json in Fragment (textView) from OkHttp Request in seperate class

If the button in DietFragment is pressed, it runs the getJson() method in HttpRequestDietPlan. Afterwards the Json(mealId, title) is used in the DietFragment.
Problem: DietFragment doesn't wait for the Request to finish.
Future isn't possible because lowest Android version needs to be 4.4
DietFragment

mealOne = rootView.findViewById(R.id.meal1);
button.setOnClickListener(new View.OnClickListener() {
#Override

hrt.getJson();
// java.lang.IllegalMonitorStateException: object not locked by thread before wait()
mealId = hrt.dietPlan.meals.get(0).mealId;

mealOne.setText(title);

Here are some suggestions:
You don't need to create a new OkHttpClient at each call, so I moved it outside the method.
Then you can pass a callback (CallHandler) to be notified when the result of the call will be available, and update your data after the result is received.
One more thing, about the deserialization, I suggest you to use a library (https://github.com/google/gson) to deserialize your json response to an instance of a class.
PS: I didn't test this code, this is just a implementation suggestion.
