推荐答案
Google Maps Android API v2不提供任何导航功能。这与Maps API的服务条款相矛盾。看一下10.4的ToS部分（iii）：
The Google Maps Android API v2 doesn't provide any functionality for navigation. It is in contradiction with Terms of Service of Maps APIs. Have a look at section 10.4 c (iii) of ToS:
没有导航。你不会使用（a）实时导航或路线指引的服务或内容;或（b）自动或自动车辆控制。
No navigation. You will not use the Service or Content for or in connection with (a) real-time navigation or route guidance; or (b) automatic or autonomous vehicle control.

如果您需要浏览导航应该创建意图，以导航模式打开Google地图应用。有一个Google地图网址可以构建一个通用的跨平台网址，以便从您的应用程序启动Google地图意图。您可以按照以下文档打开原生应用的导航模式：
If you need navigation you should create an intent that opens the Google Maps app in navigation mode. There is a Google Maps URLs that allows to construct a universal, cross-platform URL to launch Google Maps intents from your application. You can open navigation mode of native app following this documentation:
