Can GeoCoder getFromLocation method cause a NetworkOnMainThreadException to be thrown?

Question

I have an app which was tested thoroughly and working fine on Android Gingerbread (and older Android versions). I\'ve noticed from users\' reported crash errors that phones runn

Seems like these Geocoder methods and any networking or i/o calls are going to throw up a NetworkOnMainThreadException. So, if in doubt, stick it in a separate thread!

Here's an example of how to call the GeoCoder.getFromLocation() method from another thread:

new AsyncTask<GeoPoint, Void, Address>()
{
  @Override
  protected Address doInBackground(GeoPoint... geoPoints)
  {
    try
    {
      Geocoder geoCoder = new Geocoder(context);
      double latitude = geoPoints[0].getLatitudeE6() / 1E6;
      double longitude = geoPoints[0].getLongitudeE6() / 1E6;
      List<Address> addresses = geoCoder.getFromLocation(latitude, longitude, 1);
      if (addresses.size() > 0)
        return addresses.get(0);
    }
    catch (IOException ex)
    {
      // log exception or do whatever you want to do with it!
    }
    return null;
  }

  @Override
  protected void onPostExecute(Address address)
  {
    // do whatever you want/need to do with the address found
    // remember to check first that it's not null
  }
}.execute(myGeoPoint);
