每当我点击谷歌地图调试工具上的某个位置时，我都会尝试将gps位置伪装到手机中。 为此，我创建了一个gcm通知项目，并将通知推送到我的手机。 我有以下IntentService假定设置模拟位置。 但它不能正常工作。 假电子GPS应用在我的手机中正常工作。
非常感谢任何帮助。

以下官方教程中的文档缺少重要的一行。 http://developer.android.com/training/location/location-testing.html
newLocation.setElapsedRealtimeNanos(SystemClock.elapsedRealtimeNanos());至关重要。
修改以下函数后，模拟位置工作正常。
public Location createLocation(double lat, double lng, float accuracy) {
// Create a new Location
Location newLocation = new Location(LocationManager.GPS_PROVIDER);
newLocation.setLatitude(lat);
newLocation.setLongitude(lng);
newLocation.setProvider(LocationManager.GPS_PROVIDER);
newLocation.setAccuracy(1);
newLocation.setTime(new Date().getTime());
newLocation.setElapsedRealtimeNanos(SystemClock.elapsedRealtimeNanos());
return newLocation;
}
