I need the navigation function inside my app. I was using the intent google.navigation to launch the external navigator but I want to abandon it, I have some troubles and also it is not official, maybe it will disappear at all in some future Google update ....
So, I have now the route with Google api and the polyline drawn on the map. needs just to manage the vocal instruction.
Yes, with GPS I can know when I'm close to a point, but I don't have the separate instruction to repeat.
Suppose the first segment is from A to B, I just have the instruction to say at point A " go ahead for 0.5 km then turn left" but I don't have the text to repeat when I'm close to B, that should be "turn left".
Did I explain clear ?
