Google Direction API -REQUEST_DENIED

时间:2013-07-18 03:11:52

标签: android google-maps-android-api-2 google-direction

我非常沮丧 - 我有一个简单的Android应用程序,我试图在渲染地图后使用谷歌地图方向API获取方向。我得到的XML响应是REQUEST_DENIED。

请帮忙!!!我不是android的专家,还在学习技巧......这就是hptts请求: -

https://maps.googleapis.com/maps/api/directions/xml?origin=losgatos&destination=cupertino&sensor=false

我之前也发过这个问题,但没有得到任何回应。 提前谢谢..
