Known Issues

Android

Geocoder not working

Errors like Geocoder:getFromLocationName Error: grpc failed, Geocoder is not present on this device/emulator., Geocoder [...] Error or Geocoder Service not available.

Why?: The plugin checks for Geocoder.isPresent() (Android docs). One reason for Geocoder not working on a device could be that you are running your app on an emulator or on a device without Google Play Services. But Geocoder API "[...] requires a backend service that is not included in the core android framework".

Any workaround?: Yes, install Google Play services. Open SDK Tools > Tab SDK Tools > install Google Play services.
