I would like to launch Google Maps app from my app so that Google Maps is in car navigation mode, ready for user to tap Start button for the audio navigation turn by turn guide travelling from Point A to Point B. I tried with the following code:
And I got this Error: android.content.ActivityNotFoundException
Could someone kindly show me how to fix it, please?
TIA

Dim intent1 As Intent
Dim uri1 As Uri 'depends on ContentResolver
Dim lat1, lat2, lng1, lng2 As Float
'Point A: double tree by Hilton New York Downtown hotel

'Point B: Wall Street Subway station:
lat2=40.706404373426096

uri1.parse($"http://maps.google.com/maps?saddr=${lat1},${lng1}&daddr=${lat2},${lng2}"$)
intent1.Initialize(intent1.ACTION_VIEW,uri1)
'intent1.SetComponent("googlemaps")
