谷歌导航（Android 1.6的）意图回调 [英] Google Navigation (Android 1.6) intent callback

问题描述

我使用的意图来启动谷歌导航：

I'm using intents to launch Google Navigation:

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

位置是一个字符串，GPS坐标。

location is a string with GPS coordinates.

谷歌导航弹出很好，绘制了路线。他们可以返回一些类型的回调，当用户到达目的地？实施任何方式 startActivityForResult（）？

Google Navigation pops up nicely and plots the route. Can they return some type of callback when the user has reached their destination? Any way of implementing startActivityForResult()?

如果没有，这将是我最好的选择？我一直在考虑在不断位置标签后台运行的服务和结束谷歌导航，回到我的应用程序，当GPS注册，它的目标附近（因为我知道纬度/经度）。

If not, what would be my best bet? I've been considering running a service in the background that keeps tabs on the location and ending Google Navigation and returning to my app when the GPS registers that it's near the destination (because I know the latitude/longitude).

推荐答案

我想后我如何设法得到这个工作。我不使用活动回调，但我首先是一个 LocationManager 服务挂在里面。当用户得到接近目的地的坐标，我只是终止谷歌导航，并开始我的活动恢复正常。

I wanted to post how I managed to get this to work. I'm not using activity callbacks, but I am starting a service with a LocationManager hanging out in it. When the user gets close to the destination coordinates, I just terminate Google Navigation and start my activity back up.
