If you're question is regarding the Google Directions API, then you will
have to ask your question on a group or forum related to that API. This has
nothing to do with Android.

Re: [android-developers] Route Google Maps

Sorry again

*What "api"? *

API of Google Maps

*Routes of what? *

Routes between two points, like a GPS

*Who's "he"? What "points"? *
*
*
He = Application, Points that Google generate between two geographic 
localization

I go to try explain again.

I have an application that gets the current position and the user selects a 
destination, these two starting locations, it queries Google:
https://developers.google.com/maps/documentation/directions/ 

And get an xml with the places where I "turn" to reach the destination

After I read the xml, and trace a path between first and second point of 
the xml, and so on

Before the change of API, the path was perfect in the streets, but now 
appears like the image I posted

Sorry but my English is not good

After Google changed the api, I just can not generate more routes properly, 
he does it with points, and not consider the streets

That is incomprehensible.

[android-developers] Route Google Maps

[Jayme Vara]

After the XML query Google and get points, try to trace the route between them, 
but what worked before, now with updating the API. The route is generated not 
agree more, because he draws straight lines between points, not taking into 
consideration the streets on the map.

The code I use to draw:

public void draw(Canvas canvas, MapView mapView, boolean shadow) {
super.draw(canvas, mapView, shadow);

Projection proj = mapView.getProjection();

Point ponto1, ponto2;
Path caminho = new Path();
for (int i = 0; i < geoPoints.size() - 1; i++) {
ponto1 = proj.toPixels(geoPoints.get(i), null);
ponto2 = proj.toPixels(geoPoints.get(i + 1), null);

caminho.moveTo(ponto2.x, ponto2.y);
caminho.lineTo(ponto1.x,ponto1.y);

canvas.drawPath(caminho, paint);
}
}
