android google.navigation 意图返回旅行时间

Question

导航我使用：

            Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse("google.navigation:q="+url));
        mContext.startActivity(i);  

是否有可能谷歌导航返回旅行时间？

您可以使用Google Directions API 并获得包含持续时间、距离等信息的 JSON。

duration: {
text: "5 hours 22 mins",
value: 19325
},

请求（从多伦多到蒙特利尔的示例路线）
