Unity高德LBS

一、准备

高德开发者页面注册产品 

1.1 http://www.cnblogs.com/U-tansuo/archive/2013/04/25/unity3d_android_sign.html

1.2填写应用应用信息

1.3下载Android 定位SDK 

http://lbs.amap.com/api/android-location-sdk/locationsummary

解压得到 AMap_Location_V3.6.1_20171012.jar

二．新建Eclipse项目

2.1首先新建一个Android工程，在最小SDK版本里选4.0以上，不然在Unity打包的时候会报错。

2.2导入AMap_Location_V3.6.1_20171012.jar和Unity提供的JAR库classes.jar

2.5Eclipse选中我们的工程文件夹，可以先点击工具栏的Project->clean，再Project->Build Project。然后右键Export，选导出为JAR文件导出jar包

2.6Unity部分

将安卓工程的文件拷贝到Unity工程的Plugins->Android文件夹里。没有这个目录的话需要自己创建一个。文件夹目录如下，把我们刚刚导出的JAR文件放在的bin文件夹中，另外还需要把我们的安卓工程目录里把libs文件夹和res文件夹以及AndroidManifest文件拷贝进去，注意拷贝完要把libs文件夹里面的classes.jar文件删掉，不然文件会冲突

   

2.7代码GetLocationInfo.CS

using UnityEngine;
using UnityEngine.UI;

public class GetLocationInfo : MonoBehaviour {
    public Text text;
    // Use this for initialization
    void Start()
    {
        InvokeRepeating("StartLocation", 1, 5);
    }

    public void StartLocation()
    {
        AndroidJavaClass jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
        AndroidJavaObject jo = jc.GetStatic<AndroidJavaObject>("currentActivity");
        text.text = jo.Call<string>("GetInfo");
    }
}

2.8运行结果

2.9Unity打包配置

三根据返回错误代码判断错误

3.1错误代码对照表
