离线导航软件Android的 - 什么是在那里？ [英] Offline navigation software for Android - what is out there?

问题描述

进出口寻找导航软件为Android平台，我有几个要求：

Im looking for navigation software for the Android platform and I have a few requirements:

• 离线地图。该地图应存储，以便不需要互联网连接的设备/存储卡

• Offline maps. The maps should be stored on the device/memory card so no Internet-connection is required

应该有一些方法与应用通过code的互动;发送路由请求​​，获取当前位置也许将应用到前景/背景等的API，因此它可以从另一个应用程序进行控制。

There should be some way to interact with the application "through code"; sending route requests, getting current location perhaps, bringing app to foreground/background, etc. An API so it can be controlled from another application.

没有月租费

唯一一个我发现至今，以匹配上面是 Sygic导航。但是，我还没有尚未能与应用程序通信，即使他们说，是可以做到的。仍在调查这...

The only one I found so far to match the above is Sygic Navigation. However, I havent yet been able to communication with the app even though they say that it can be done. Still investigating that...

推荐答案

这是API将很难获得，主要是由于数据的权限。

An API will be difficult to obtain, mostly due to data rights.

例如，谷歌地图Android版的部分原因有一堆它的API限制，是因为谷歌并不拥有所有需要，使他们的地图数据，并尽自己的导航。他们许可了一些数据，他们不得不忍受这些许可条款。

For example, part of the reason Google Maps for Android has a bunch of its API restrictions is because Google does not own all the data needed to make their maps and do their navigation. They license some of that data, and they have to live with those license terms.

最好的答案长期可能是一些掠走的 OpenStreetMap的，因为这是人群来源和创意共享许可。不过，我不认为他们有一个解决方案，涵盖您的要求为present，至少在Android上。

The best answer long-term may be something made off of OpenStreetMap, since that's crowd-sourced and Creative Commons-licensed. However, I don't think they have a solution that covers your requirements at present, at least on Android.
