Q:

Problem launching Google Navigation

i tried since many hours to launch navigation from my app.
I want navigation without destination.
i tried with 
        Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse("google.navigation:q="));
        startActivity(i);

That launches navigation but with destination not found
I tried too to launch processName, packageName with startIntent with com.google.android.apps.maps,
com.google.android.apps.maps:driveabout and 
**com.google.android.maps.driveabout.app.DestinationActivity
with no succes too :/
an idea ?

A:

Google Navigation does not have any documented and supported Intent filters. It is not designed to be integrated from third party apps.

A:

The following code should work... 
String url = "google.navigation:q="+startPos.getLatitude()+","+startPos.getLongitude();
Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse(url));            
startActivity(i);
