在导航应用中使用模拟位置

我试图开发一个应用程序,将模拟通过谷歌的导航应用程序的路线。 我发现了一些很好的例子,说明如何在本网站的某些其他post中实现模拟位置提供程序( Android设备上的模拟位置? )。
通过对源代码http://www.cowlumbus.nl/forum/MockGpsProvider.zip的简单修改,我的模拟位置显示在Google的地图应用程序中。 (唯一的变化是到LocationManager.GPS_PROVIDER的模拟提供者名称)。
我的问题是,当我打开导航应用程序,它说“searchGPS信号”。 我仍然看到我的位置在地图上移动; 但是,它不会生成到目的地的路线。 我想知道是否有人知道我需要做什么来伪造导航,看到我的模拟位置作为GPS信号。
谢谢。

这是我错过的东西:

 location.setLatitude(latitude); location.setLongitude(longitude); location.setAccuracy(16F); location.setAltitude(0D); location.setTime(System.currentTimeMillis()); location.setBearing(0F); 

另外,重要的是要确定导航方位。 否则,路由更新将不准确。
