如何解决android studio中不显示地图方向？

Question

当我输入位置时，它没有显示（起点和终点）的路线：

这些是日志：

为了让我们更好地帮助您，您需要提供有关您迄今为止尝试过的内容或无效代码的详细信息。

一般来说，如果你需要打开一张地图，显示从 A 点到 B 点的方向，这里有一个有效的代码。

 Uri.Builder directionsBuilder = new Uri.Builder()
                .scheme("https")
                .authority("www.google.com")
                .appendPath("maps")
                .appendPath("dir")
                .appendPath("")
                .appendQueryParameter("api", "1")
                .appendQueryParameter("destination", latitude + "," + longitude);

        startActivity(new Intent(Intent.ACTION_VIEW, directionsBuilder.build()));
