Android: grpc failed on Nexus 5

Question

I'm working with geocoder. On all devices the code works fine but on a Nexus 5 phone there is an exception in the logs.

My code:

override fun fromAddress(address: Address): Observable<Geolocation> {
    val location = geocoder.getFromLocationName("${address.street} ${address.number}, ${address.postcode}, ${address.city}", LOCATIONS_MAX_RESULTS).first()
    return Observable.just(Geolocation(latitude = location.latitude, longitude = location.longitude))
}

My Error:

java.io.IOException: grpc failed

I read everywhere the solution reinstall Android studio or update Android studio but this doesn't works for me.

Which version of playservices are you usingg? Which Android version is the Nexus 5 running? Have the other devices you tested with the same Android version installed ? – Huckaby

Is that the only exception in the log? Is there no cause exception? – Burning

Answer 1

I faced the same issue when i was getting address from latitude and longitude. I was using emulator and another truck screen device. On both devices It gives the same problem. GRPC failed. But when I run this code on my mobile and another Samsung device, It worked perfectly. I have to run it on that truck screen device. So I found a solution that to use Google Maps Location API to get location from latitude and longitude.

String url = "https://maps.googleapis.com/maps/api/geocode/json?latlng="+log.getLattitude()+","+log.getLongitude()+"&key="+context.getResources().getString(R.string.geocodeAPiKey);

or simply

String url = "https://maps.googleapis.com/maps/api/geocode/json?latlng=33.25845,75.256489&key=API_KEY;

You can search for this like Reverse Geocoding

By this link you can get API Key for Geocoding

https://developers.google.com/maps/documentation/geocoding/get-api-key

In the result you will get a JSONObject. Get its first element in the JSONArray, and get the address from it like this

    JSONObject info = new JSONObject(result);
    JSONObject locationInfo = info.getJSONArray("results").getJSONObject(0);
    String locationDescription = locationInfo.getString("formatted_address");

This is reverse Geocoding. If you want to do simple Geocoding. Its almost same like this. I had the Reverse Geocoding code so i had shared that with you.

For more help and support please visit this link Google Geocoding API

I faced the same issue on Nexus 5X and a cause was in using VPN.
