4,762 Pointsmaking http get request with OkHttp call.execute() crashes app
I was following along the video, but as soon as I made the get request the app instantly crashes. The logs are not that helpful to me.
the relevant log message is just:

my code at that section is
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
String apiKey = "blanked out ******";
Double latitude = 37.8267;
Double longtitude = -122.4233;
String forecastUrl = "https://api.darksky.net/forecast/" +
apiKey + "/" + latitude + "," + longtitude;
Request request = new Request.Builder()
.url(forecastUrl)
.build();
Call call = client.newCall(request);
try {
Response response = call.execute();
} catch (IOException e) {
Log.e(TAG, "IO Exception caught: ", e);
}
Does anyone have any idea what's going on?
Thanks in advance

4,762 Pointshey I figured it out, sorry for the stupid question. Should've just watched until the end of the video.
