It is not possible to get data from the stream in which I request the coordinates of the location.

public void requestCoordinates(final String input, final ICoordinateReceiver receiver, final boolean updateTimezone) { try { final String URL = PLACE_API_BASE_URL + "?key=" + API_KEY + "&address=" + URLEncoder.encode(input, "utf8"); OkHttpClient client = new OkHttpClient(); Request request = new Request.Builder() .url(URL) .build(); Call call = client.newCall(request); call.enqueue(new Callback() { @Override public void onFailure(Request request, IOException e) { Log.d(TAG, "Request to Google Maps Geocoding API failure"); } @Override public void onResponse(Response response) throws IOException { String jsonData = response.body().string(); try { JSONObject jsonObject = new JSONObject(jsonData); JSONArray jsonArray = jsonObject.getJSONArray("results"); String status = jsonObject.getString("status"); if (!status.equals("OK")) { String log = "GoogleMapsGeocoding: url <" + URL + "> response status <" + status + ">"; throw new JSONException(log); } JSONObject jsonGeometry = new JSONObject(jsonArray.getJSONObject(0).getString("geometry")); JSONObject jsonLocation = new JSONObject(jsonGeometry.getString("location")); Coordinate coordinate = new Coordinate(); coordinate.setLatitude(Double.parseDouble(jsonLocation.getString("lat"))); coordinate.setLongitude(Double.parseDouble(jsonLocation.getString("lng"))); receiver.updatePositionCoordinate(input, coordinate); if (updateTimezone) { GoogleMapsTimezone googleMapsTimezone = new GoogleMapsTimezone(); googleMapsTimezone.requestTimezone(input); } } catch (JSONException e) { Log.e(TAG, e.getLocalizedMessage()); AppUtils.showInfoMessage(MyApplication.getAppContext().getString(R.string.invalid_lang_long_used)).show(); if (Fabric.isInitialized()) { Crashlytics.logException(e); } } } }); } catch (UnsupportedEncodingException e) { AppUtils.showInfoMessage(MyApplication.getAppContext().getString(R.string.invalid_lang_long_used)).show(); Log.e(TAG, e.getLocalizedMessage()); } }

I transfer the interface on which it is necessary to return the obtained data. Is it not possible to do this? What is better to do in this case? AsyncTask?

Interface implementation

 GoogleMap map; public void deleteAllMarkers() { map.clear(); } @Override public void updatePositionCoordinate(String city, Coordinate coordinate) { deleteAllMarkers(); setNewMarker(coordinate, city); setCameraPosition(coordinate, getDefaultZoom(), 0, 0); }

    According to the error, you would need to call this method (interface method) in the main application thread. Try passing the Activity to your request (or linking the variable-link to the interface to activate, if the implementation is in activation), call its runOnUiThread() method and already in it call your method, for a fall.
