如何使用GDK在卡片上显示静态地图？

在 Mirror API 中我们可以使用类似的东西：

<img src="glass://map?w=240&h=360&marker=0;42.369590,
      -71.107132&marker=1;42.36254,-71.08726&polyline=;42.36254,
      -71.08726,42.36297,-71.09364,42.36579,-71.09208,42.3697,
      -71.102,42.37105,-71.10104,42.37067,-71.1001,42.36561,
      -71.10406,42.36838,-71.10878,42.36968,-71.10703"
      height="360" width="240">

它可以在卡片上呈现漂亮的 Glass 优化地图。

如何使用 GDK 在 Activity 中做同样的事情？

我最终编写了这个方法，它将用户当前位置显示为蓝点，将场地位置显示为红点：

public static String getMapUrl(double latitude, double longitude, double currentLat, double currentLon, int width, int height) {
        try {
            String raw = "https://maps.googleapis.com/maps/api/staticmap?sensor=false&size=" + width + "x" + height +
                "&style=feature:all|element:all|saturation:-100|lightness:-25|gamma:0.5|visibility:simplified" +
                "&style=feature:roads|element:geometry&style=feature:landscape|element:geometry|lightness:-25" +
                "&markers=icon:" + URLEncoder.encode("http://mirror-api.appspot.com/glass/images/map_dot.png",
                "UTF-8") + "|shadow:false|" + currentLat + "," + "" + currentLon+"&markers=color:0xF7594A|" + latitude + "," + longitude;
            return raw.replace("|", "%7C");
        } catch (UnsupportedEncodingException e) {
            return null;
        }
    }

它看起来像这样：
