String key = "Key";
LatLng[] fLatLong = getLatLong(fromPoint);
LatLng[] tLatLong = getLatLong(toPoint);
try{    
    GeoApiContext distCalcer = new GeoApiContext.Builder()
        .apiKey(key)
        .build();

    DistanceMatrixApiRequest req = DistanceMatrixApi.newRequest(distCalcer); 
    DistanceMatrix result = req.origins(fLatLong)
           .destinations(tLatLong)
           .await();
   DistanceMatrixElement[] row =  result.rows[0].elements;
   System.out.println(row[0].toString());

}catch(Exception e){
    e.getStackTrace();
}

please help thank you!
