throwing java.lang.UnsupportedOperationException on some devices

问题

I've found out, that my app, that uses the yandex map kit, on some devices crashes with such an exception. What does this "java.lang.UnsupportedOperationException" exception means???

Here is the doInBackground method:

  private class SetRightMapDisplayAddress extends AsyncTask<String, Void, List<Address>> {

        @Override
        protected List<Address> doInBackground(String... params) {
            Log.d(TAG, "doinbackground SetRightMapDisplayAddress started");
            long startTime= System.currentTimeMillis();
            long threadId = Thread.currentThread().getId();
            Log.d(TAG, String.format("The thread id is: %d", threadId));

            context = getActivity();
            String placeName = params[0];
            Geocoder geocoder = new Geocoder(context);
            List<Address> addressList = null;
            try {
                addressList = geocoder.getFromLocationName(placeName, 3);
            } catch (IOException e) {
                e.printStackTrace();  //To change body of catch statement use File | Settings | File Templates.
            }
            int returnedAddresses = addressList.size();
            Log.d(TAG, String.valueOf(returnedAddresses));
            long endTime = System.currentTimeMillis();
            Log.d(TAG, String.valueOf(startTime-endTime));
            Log.d(TAG, "doinbackground SetRightMapDisplayAddress ended");
            return addressList;
        }

Thanks in advance for your answers!!

回答1:

java.lang.UnsupportedOperationException: query: Not supported yet - content://ru.yandex.device.id.maps/device_id

Based on the exception description, I can suggest that the method isn't implemented yet by the framework authors, so you might contact the support team for clarifications.
