本文介绍了一个基于Android平台的地图路径规划程序。该程序使用Google Maps API获取起点和终点坐标，并显示路径规划结果。用户可以在Android设备上输入起始地点和目的地，程序将返回两地的详细地址并展示路线。

droid = android.Android()

for ad in address:
    print ad['long_name']

location = js['results'][0]['geometry']['location']
startLat = location['lat']
startLng = location['lng']
print js

city = droid.dialogGetInput(u"geocode",u"请输入终点 end:",u'zhuhai').result

for ad in address:
    print ad['long_name']

location = js['results'][0]['geometry']['location']
endLat = location['lat']
endLng = location['lng']
print js

# 路径规划:
url = 'http://maps.google.com/maps?f=d&saddr=%s%%20%s&daddr=%s%%20%s&hl=zh' % (startLat,startLng,endLat,endLng)
print url
droid.startActivity('android.intent.action.VIEW',url)

在 android 4.1 pad 上测试通过.
