[Wear OS Q&A, Help & Troubleshooting] andy.belgium:
Hello, i'm trying to display a Google map on my Sony SmartWatch3.

In my wear layout, i'm using a MapFragment with this code :

<fragment
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/mapFragment"
class="com.google.android.gms.maps.MapFragment"/>

My wear main activity implements OnMapReadyCallback :

@Override
public void onMapReady(GoogleMap map) {
SupportMapFragment fragment = ( SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.mapFragment);
// Getting Google Map
GoogleMap googleMap = fragment.getMap();

Finally, i've got this error :

Is it really possible to display a map on a watch ? If yes, can you tell me how ? :)

Thanks in advance :)
