[GraphHopper] Android: Unload graph

[Peter K]

Hey Emux,

yes graph and locationIndex don't get null but they are lightweight and
no longer usable. But I'll check if proper exceptions are thrown if they
are still used. Maybe a better solution for Android can be:

onDestroy(...) { // as you suggested
  hopper.close()
  // include the following, so that a new instance has to be created for
a new onCreate call:
  hopper=null
  System.gc()
}

Regards,
Peter.
