Android warning response.body().string();

Hello.

I am getting this warning in this code: myString = response0.body().string();

Method invocation ‘string’ may produce ‘java.lang.NullPointerException’

The problem appears in string(). This code is inside try-catch.

How can I solve this safety? I searched in StackOverflow but I found nothing.

The app is working perfectly, it is just a warning.

The warning can be suppressed for a normal response. The body is only null for a cached response or network response.

replace response.body().string() with String successResponse = new Gson().toJson(response.body());

full code:

call.enqueue(new Callback<Object>() {
        @Override
        public void onResponse(@NonNull Call<Object> call, @NonNull Response<Object> response) {
            if (response.isSuccessful()) {
                Gson gson = new Gson();
                String successResponse = gson.toJson(response.body());
                Log.d(LOG_TAG, "successResponse: " + successResponse);
            } else {
                try {
                    if (null != response.errorBody()) {
                        String errorResponse = response.errorBody().string();
                        Log.d(LOG_TAG, "errorResponse: " + errorResponse);
                    }
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        }

        @Override
        public void onFailure(@NonNull Call<Object> call, @NonNull Throwable t) {
        }
    });
