[Solved] Retrofit give null pointer exception

by


When you have an error on your response, your response body is null.
You have to use the code from the Response and if you want to get the data from the error use the errorBody():

public void onResponse(Call<SalaryListModel> call, Response<SalaryListModel> response) {
            if (response.isSuccessful()) {
                Log.e(TAG, "onResponse: calling");
                if (response.body().getStatus_code() == 200) {
                    Log.e(TAG, "onResponse: calling 200");

                }
            } else {
                Log.e(TAG, "onResponse: else--");
                if (response.code() == 500) {
                    Log.e(TAG, "onResponse: 500");

                    //and if you want to parse your error body try this

                    /*
                    try {
                        Gson gson = new Gson();
                        YourErrorClass error = gson.fromJson(response.errorBody().charStream(), YourErrorClass.class);

                    } catch (Exception e) {
                         Log.e(TAG, "onResponse error: " + e.getMessage());
                    }*/



                } else if (response.code() == 406) {
                    Log.e(TAG, "onResponse: 406");
                } else {
                    Log.e(TAG, "onResponse: esle");
                }

            }

        }
