I'm trying to get directions using the Google Maps Directions API.

It's pretty much what Google's own documentation shows to do https://developers.google.com/maps/documentation/directions/get-directions#maps_http_directions_toronto_montreal-java

The requested URL works when pasted into a browser, so that's correct.

And I can see an additional Directions API request after running this.

The response has no JSON directions in it.

What am I doing wrong?

private class getDirections extends AsyncTask<LatLng, Void, String> {
        @Override
        protected String doInBackground(LatLng... point) {
            try {
                OkHttpClient client = new OkHttpClient().newBuilder()
                        .writeTimeout(60, TimeUnit.SECONDS)
                        .readTimeout(60, TimeUnit.SECONDS)
                        .build();
                Request request = new Request.Builder()
                        .url("https://maps.googleapis.com/maps/api/directions/json?origin=Toronto&destination=Montreal&key=" MAPS_API_KEY)
                        .method("GET", null)
                        .build();
                    Response response = client.newCall(request).execute();
                    Log.d("response1", response.message());
                    if (response.message() == "") {
                        return "error";
                    }
                    return response.body().string();
                } catch (IOException e) {
                    e.printStackTrace();
                }
                return null;
        }

    }

CodePudding user response：

response.message() is not the body, it's just the string after the 200.

HTTP/1.1 200

check the response numerically or via if (!response.isSuccessful) {

This query is working for me.
