Android Google Map v2 draw a route

I have a Google Map fragment:

<fragment xmlns:android="http://schemas.android.com/apk/res/android"
            xmlns:tools="http://schemas.android.com/tools"
            android:id="@+id/map"
            android:name="com.google.android.gms.maps.SupportMapFragment"
            class="com.google.android.gms.maps.SupportMapFragment"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            tools:context="my.package.MapsActivity"
            android:layout_marginTop="?actionBarSize"/>

I get my location like this:

private void getMyLocation() {
    LatLng latLng = new LatLng(mMap.getMyLocation().getLatitude(), mMap.getMyLocation().getLongitude());
    CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngZoom(latLng, 16);
    mMap.animateCamera(cameraUpdate);
}

You need to show the route to the specified coordinates, as in the photo:

This library helped. My code:

Route supportRoute = new Route();

LatLng source = new LatLng(mMap.getMyLocation().getLatitude(), mMap.getMyLocation().getLongitude());
LatLng dest= new LatLng(destLat, destLog);

                supportRoute.drawRoute(mMap, MapsActivity.this, source, dest, true, "en");
