Why does my code not call the api server, and why do I have OpenGLRenderer errors in my logcat?

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    String forecastURL = "https://api.forecast.io/forecast/"
            + apiKey
            + "/"
            + latitude
            + ","
            + longitude;

    if (isNetworkAvailable()) {
        OkHttpClient client = new OkHttpClient();
        Request request = new Request.Builder().url(forecastURL).build();

        Call call = client.newCall(request);
        call.enqueue(new Callback() { //asynchronous call
            @Override
            public void onFailure(Request request, IOException e) {
            }

                try {
                    String jsonDATA = response.body().string();
                    Log.v(TAG, jsonDATA);
                    if (response.isSuccessful()) {
                        mCurrentWeather = getCurrentDetails(jsonDATA);
                    }
                    else {
